Abstract
The One Health approach of antimicrobial resistance highlighted the role of the aquatic environment as a reservoir and dissemination source of resistance genes and resistant bacteria, especially due to anthropogenic activities. Resistance to extended-spectrum cephalosporins (ESC) conferred by extended-spectrum beta-lactamases (ESBLs) in E. coli has been proposed as the major marker of the AMR burden in cross-sectoral approaches. In this study, we investigated wastewater, surface water and seawater that are subjected to official water quality monitoring in Monastir, Tunisia. While all but one sample were declared compliant according to the official tests, ESC-resistant bacteria were detected in 31 (19.1 %) samples. Thirty-nine isolates, coming from urban, industrial and surface water in Monastir, were collected and characterized using antibiograms and whole-genome sequencing. These isolates were identified as 27 Escherichia coli (69.3 %) belonging to 13 STs, 10 Klebsiella pneumoniae (25.6 %) belonging to six STs, and two Citrobacter freundii (5.1 %). We observed the persistence and dissemination of clones over time and in different sampling sites, and no typically human-associated pathogens could be identified apart from one ST131. All isolates presented a blaCTX-M gene - blaCTX-M-15 (n = 22) and blaCTX-M-55 (n = 8) being the most frequent variants - which were identified on plasmids (n = 20) or on the chromosome (n = 19). In conclusion, we observed ESC resistance in rather ubiquitous bacteria that are capable of surviving in the water environment. This suggests that including the total coliform count and the ESBL count as determined by bacterial growth on selective plates in the official monitoring would greatly improve water quality control in Tunisia.

Abstract
OBJECTIVES Wild birds are vectors of antimicrobial resistance. Birds living in close contact with humans or other animals, like feral pigeons (Columba livia), might be especially prone to acquire resistance genes such as those encoding extended-spectrum beta-lactamases (ESBLs) and carbapenemases. METHODS Cloacal samples (n = 206) of free-living feral pigeons (C. livia) were collected in Sousse and Monastir, Tunisia. Antimicrobial susceptibility profiles were determined by disc-diffusion, and resistant isolates were short- and long-read whole-genome sequenced. Sequence analysis was performed using tools of the Centre for Genomic Epidemiology, and Phylogenetic analysis was performed based on the core-genome MLST. RESULTS Fourteen (14/206, 6.8%) pigeons harboured Enterobacterales resistant to last-generations cephalosporins, of which 10 were CTX-M-15- or CTX-M-27-producers, while two (1.0%) carried a VIM-2-producing Pseudomonas putida. Positive pigeons lived on four different livestock farms. Three STs (ST206, ST5584, ST8149) were identified among E. coli, of which ST5584 and ST8149 were found in two different farms. Genetic diversity was also observed in Enterobacter cloacae and P. putida isolates. The blaCTX-M-27 genes were chromosomally encoded, while the blaCTX-M-15 genes were carried on highly similar IncF/F-:A-:B53 plasmids. The blaVIM-2 gene was located on a class 1 integron co-harbouring several resistance genes. CONCLUSION Pigeons living on livestock farms carried clinically important resistance genes encoding ESBLs and carbapenemases. Our results evidenced that both clonal (ST8149 and ST5584) and plasmidic (IncF/F-:A-:B53) transfers played a role in the spread of resistance genes among pigeons. Further studies are needed to identify factors favouring the transfer and persistence of resistance genes within the pigeon communities.

Abstract
The Acinetobacter baumannii clonal lineage ST25 has been identified in humans and animals and found associated with outbreaks globally. To highlight possible similarities among ST25 A. baumannii of animal and human origins and to gather clues on the dissemination and evolution of the ST25 lineage, we conducted a phylogenetic analysis on n = 106 human and n = 35 animal A. baumannii ST25 genomes, including 44 sequenced for this study. Resistance genes and their genetic background were analyzed, as well. ST25 genomes are clustered into four clades: two are widespread in South America, while the other two are largely distributed in Europe, Asia and America. One particular clade was found to include the most recent strains and the highest number of acquired antibiotic resistance genes. OXA-23-type carbapenemase was the most common. Other resistance genes such as blaNDM-1, blaPER-7, and armA were found embedded in complex chromosomal regions present in human isolates. Genomic similarity among multidrug resistant ST25 isolates of either animal or human origin was revealed, suggesting cross-contaminations between the two sectors. Tracking the clonal complex ST25 between humans and animals should provide new insights into the mode of dissemination of these bacteria, and should help defining strategies for preserving global health.

Abstract
Carbapenem-resistant Acinetobacter baumannii (CRAB) strains can cause severe and difficult-to-treat infections in patients with compromised general health. CRAB strains disseminate rapidly in nosocomial settings by patient-to-patient contact, through medical devices and inanimate reservoirs. The occurrence of CRAB in patients residing in the intensive care units (ICUs) of the Sahloul University hospital in Sousse, Tunisia is high. The objective of the current study was to determine whether the surfaces of items present in five ICU wards and the medical personnel there operating could serve as reservoirs for CRAB strains. Furthermore, CRAB isolates from patients residing in the ICUs during the sampling campaign were analyzed for genome comparison with isolates from the ICUs environment. Overall, 206 items were screened for CRAB presence and 27 (14%) were contaminated with a CRAB isolate. The items were located in several areas of three ICUs. Eight of the 54 (15%) screened people working in the wards were colonized by CRAB on the hands. Patients residing in the ICUs were infected with CRAB strains sharing extensive genomic similarity with strains recovered in the nosocomial environment. The strains belonged to three sub-clades of the internationally disseminated clone (ST2). A clone emerging in the Mediterranean basin (ST85) was detected as well. The strains were OXA-23 or NDM-1 producers and were also pan-aminoglycoside resistant due to the presence of the armA gene. Hygiene measures are urgent to be implemented in the Sahloul hospital to avoid further spread of difficult-to-treat CRAB strains and preserve health of patients and personnel operating in the ICU wards.

Abstract
European starlings are widespread migratory birds that have already been described as carrying bacteria resistant to extended-spectrum cephalosporins (ESC-R). These birds are well known in Tunisia because they spend the wintertime in this country and are hunted for human consumption. The goal of our study was to estimate the proportion of ESC-R in these birds and to characterize the collected isolates using whole-genome sequencing. Results showed that 21.5% (42/200) of the birds carried either an extended-spectrum beta-lactamase (ESBL) or an acquired AmpC gene. Diverse bla CTX-M genes were responsible for the ESBL phenotype, bla CTX-M-14 being the most prevalent, while only bla CMY-2 and one bla CMY-62 were found in AmpC-positive isolates. Likewise, different genetic determinants carried these resistance genes, including IncHI2, and IncF plasmids for bla CTX-M genes and IncI1 plasmids for bla CMY-2 genes. Three chromosomally encoded bla CTX-M-15 genes were also identified. Surprisingly, species identification revealed a large proportion (32.7%) of Escherichia marmotae isolates. This species is phenotypically indistinguishable from Escherichia coli and has obviously the same capacity to acquire ESC-R genes. Our data also strongly suggest that at least the IncHI2/pST3 plasmid can spread equally between E. coli and E. marmotae. Given the potential transmission routes between humans and animals, either by direct contact with dejections or through meat preparation, it is important to closely monitor antimicrobial resistance in European starlings in Tunisia and to set up further studies to identify the sources of contamination of these birds. IMPORTANCE The One Health concept highlighted knowledge gaps in the understanding of the transmission routes of resistant bacteria. A major interest was shown in wild migratory birds since they might spread resistant bacteria over long distances. Our study brings further evidence that wild birds, even though they are not directly submitted to antibiotic treatments, can be heavily contaminated by resistant bacteria. Our results identified numerous combinations of resistance genes, genetic supports, and bacterial clones that can spread vertically or horizontally and maintain a high level of resistance in the bird population. Some of these determinants are widespread in humans or animals (IncHI2/pST3 plasmids and pandemic clones), while some others are less frequent (atypical IncI1 plasmid and minor clones). Consequently, it is essential to be aware of the risks of transmission and to take all necessary measures to prevent the proportions of resistant isolates from increasing uncontrollably.

Abstract
Resistance to extended-spectrum cephalosporins (ESC) and carbapenems in Enterobacterales is a major issue in public health. Carbapenem resistance in particular is associated with increased morbidity and mortality. Moreover, such resistance is often co-harbored with resistance to non-beta-lactam antibiotics, and pathogens quickly become multi-drug-resistant (MDR). Only a few studies have been published on AMR in Libyan hospitals, but all reported worrisome results. Here, we studied 54 MDR isolates that were collected from 49 patients at the Tripoli University Hospital between 2019 and 2021. They were characterized using phenotypic methods, PCR and PFGE, and a sub-set of isolates were short- and long-read whole-genome sequenced. The results showed the frequent occurrence of Klebsiella pneumoniae (49/54), among which several high-risk clones were responsible for the spread of resistance, namely, ST11, ST17, ST101 and ST147. ESC and carbapenem resistance was due to a wide variety of enzymes (CTX-M, OXA-48, NDM, KPC), with their corresponding genes carried by different plasmids, including IncF-IncHI2 and IncF-IncR hybrids. This study highlights that implementation of infection prevention, control and surveillance measures are needed in Libya to fight against AMR.

Abstract
Despite the fact that the selective pressure of antibiotics on wild birds is supposed to be very weak, they are considered potential vectors of antimicrobial resistance (AMR). Obligate scavengers such as vultures can present high proportions of resistance to extended-spectrum cephalosporins (ESC) and multi-drug-resistant (MDR) bacteria, partially due to feeding stations that are provisioned with livestock carcasses from intensive farming. Here we investigated whether griffon vultures (Gyps fulvus) from two populations located in the French Alps, which feed on livestock carcasses from extensive farms, may carry such resistant bacteria. Phenotypic and genotypic characterization showed an 11.8% proportion of ESC-resistant bacteria, including five extended-spectrum beta-lactamase (ESBL)-producing and one AmpC-producing E. coli. The five ESBL-positive E. coli were clonal and all came from the same vulture population, proving their spread between animals. The ESBL phenotype was due to a blaCTX-M-15 gene located on the chromosome. Both ESBL- and AmpC-positive E. coli belonged to minor STs (ST212 and ST3274, respectively); interestingly, ST212 has already been identified in wild birds around the world, including vultures. These results suggest that actions are needed to mitigate the spread of MDR bacteria through wild birds, particularly in commensal species.

Abstract
Introduction Colistin-resistance widely disseminated in food-producing animals due to decades of colistin use to treat diarrhea. The plasmid-borne mcr-1 gene has been extensively reported from bovine, swine and chicken worldwide, but smaller productions such as the goat farming sector were much less surveyed. Methods We looked for colistin-resistant isolates presenting plasmid-borne genes of the mcr family in both breeding (n=80) and fattening farms (n=5). Localization of the mcr-1 gene was performed using Southern blot analysis coupled to short-read and long-read sequencing. Results Only the mcr-1 gene was identified in 10% (8/80) of the breeding farms and four over the five fattening farms. In total, 4.2% (65/1561) of the animals tested in breeding farms and 60.0% (84/140) of those tested in fattening farms presented a mcr-1-positive E. coli. The mcr-1 gene was located either on the chromosome (32.2%) or on IncX4 (38.9%) and IncHI2 (26.8%) plasmids. As expected, both clonal expansion and plasmidic transfers were observed in farms where the mcr-1 gene was carried by plasmids. Tn6330 transposition was observed in the chromosome of diverse E. coli sequence types within the same farm. Discussion Our results show that the mcr-1 gene is circulating in goat production and is located either on plasmids or on the chromosome. Evidence of Tn6330 transposition highlighted the fact that chromosomal insertion does not impair the transmission capability of the mcr-1 gene. Only strict hygiene and biosecurity procedures in breeding farms, as well as a prudent use of antibiotics in fattening farms, can avoid such complex contamination pathways.

Abstract
BACKGROUND Compared with healthcare settings, the role of veterinary hospitals in the spread of extended-spectrum cephalosporin- and carbapenem-resistant (ESC-R/CP-R) bacteria has been overlooked. OBJECTIVES To investigate using genome-based approaches the dynamics of ESC-R and CP-R Enterobacterales among 125 dogs admitted to the same veterinary hospital over a 4 month period. METHODS Dogs (n = 125) were sampled within 48 h of admission and at discharge. ESC-R/CP-R were phenotypically characterized and whole-genome sequenced using short- and long-read technologies. Phylogenetic analyses were performed using appropriate pipelines. RESULTS ESC-R/CP-R prevalence in dogs was 4.8% (6/125) upon admission and reached 24.8% (31/125) at discharge, reflecting multiple acquisitions of ESBL/AmpC and OXA-48-positive Enterobacterales during hospitalization. Indistinguishable or closely related isolates were found within dogs, shared between dogs, and shared between dogs and their environment, suggesting numerous clonal and plasmid spreads. Even though carbapenems are not licensed for use in companion animals, a wide distribution of the blaOXA-48/IncL plasmid was evidenced across different bacterial species and dogs. CONCLUSIONS This study highlights nosocomial acquisitions of ESBL/AmpC and carbapenemase-producing Enterobacterales by companion animals and the risk of further transmission within the community in a One Health perspective. Reinforced infection prevention and control measures and screening procedures are urgently needed in small animal veterinary settings where advanced therapeutics and intensive care is provided.

Abstract
Aquaculture is a rapidly expanding sector in which it is important to monitor the occurrence of multi-drug resistant (MDR) bacteria. The presence of extended-spectrum β-lactamase (ESBL-) or carbapenemase-producing Enterobacterales is a commonly used indicator of the resistance burden in a given sector. In this study, 641 pieces of farmed fish (sea bream and sea bass), as well as 1075 Mediterranean clams, were analyzed. All ESBL- and carbapenemase-producing Enterobacterales collected were whole-genome sequenced. The proportion of ESBL-producing Enterobacterales was 1.4% in fish and 1.6% in clams, carried by Escherichia coli (n = 23) and Klebsiella pneumoniae (n = 4). The ESBL phenotype was exclusively due to the presence of blaCTX-M genes, the most frequent one being blaCTX-M-15. The blaCTX-M-1 gene was also identified in six E. coli, among which four were carried by IncI1/pST3 plasmids, possibly betraying an animal origin. Carbapenemases were absent in fish but identified in two K. pneumoniae isolates from clams (blaNDM-1 and blaOXA-48). Several sequence types (STs) identified were associated with human MDR clones such as E. coli ST131 and ST617, or K. pneumoniae ST307 and ST147. Our results might indicate that bacteria from hospital or farm effluents can reach the open sea and contaminate seafood and fish that are living or raised nearby. Therefore, monitoring the quality of water discharged to the sea and the presence of MDR bacteria in seafood is mandatory to ensure the quality of fishery products.

Abstract
Necrotoxigenic Escherichia coli 2 (NTEC2) are defined as E. coli producing the toxin known as cytotoxic necrotizing factor 2 (CNF2), a potent toxin primarily found in bovine but also in humans. NTEC2 are mostly associated with bovine, and cnf2 is known to be carried by pVir-like plasmids. In this study, we looked for NTEC2 in a collection of E. coli collected between 2011 and 2018 in French bovine. Thirty-two isolates, collected from both sick (n=19) and healthy (n=13) animals, were identified and characterized using whole-genome sequencing. One F74 plasmid of this bacterial collection was long-read sequenced: its size was 138 121 bp and it carried the cnf2, F17cA-eG, cdtB, iutA, iucC, and ompP virulence factors (VFs), but no resistance gene. A large variety of genetic backgrounds was observed, but all cnf2-carrying plasmids belonged to the IncF family, and most of them (78.1%) were of the F74 group. Similar F74 plasmids were also reported from bovine in the United Kingdom and USA, as identified in the publically available databases. Consequently, these F74 plasmids, which are widely disseminated among E. coli from cattle in the French territory, are vectors of virulence determinants that largely went unnoticed until now.

Abstract
Background WHO considers ESBL- and carbapenemase-producing Klebsiella pneumoniae a major global concern. In animals, ESBL- and carbapenemase-producing K. pneumoniae of human-related ST11, ST15 and ST307 have been reported, but not in the context of large WGS-based One Health investigations. Objectives To perform comparative phylogenomics on a large collection of multidrug-resistant (MDR) K. pneumoniae recovered from diseased companion animals and humans. Methods MDR K. pneumoniae (n = 105) recovered from companion animals in France during 2010–18 were phenotypically characterized. All isolates were whole-genome sequenced using the NovaSeq technology and phylogenomic analysis across animal and human K. pneumoniae was performed using appropriate pipelines. Results blaCTX-M-15, blaDHA-1 and blaOXA-48 were strongly associated with IncFIIk, IncR and IncL plasmids, respectively. When compared with human K. pneumoniae genomes, four groups of closely related French human and animal isolates belonging to ST11, ST15 and ST307 were detected, suggesting the circulation of clones between the human and animal sectors at country level. A large cluster of 31 ST11-KL105 animal isolates from France and Switzerland suggested it corresponds to a sub-lineage that is particularly well-adapted to the animal host. Conclusions This study demonstrates the spread of blaCTX-M-15-carrying ST15 and ST307, and blaDHA-1-carrying ST11 K. pneumoniae clones in animal populations. ST11 was the main vector of blaOXA-48/IncL, despite the absence of carbapenem use in French animals. Comparative phylogenomics suggests cross-transmission of K. pneumoniae sub-lineages more prone than others to colonize/infect the animal host. Our data also evidenced the emergence of convergent hypervirulent and MDR K. pneumoniae in animals.

Abstract
OBJECTIVES Knowledge on the dynamic of MDR Escherichia coli in the human community is still limited, especially in low- and middle-income countries. Our goal was to decipher the dynamics of E. coli lineages and plasmids resistant to ESC, carbapenem and colistin within and between food workers in Lebanon using genomic-based approaches. METHODS Eighty-four healthy adults working in three bakeries were sampled twice at a 6 monthly interval. E. coli resistant to ESC (ESC-E), carbapenem (CP-E) and colistin (CO-E) were collected on selective plates. Non-duplicate isolates were whole-genome sequenced using the Illumina technology and plasmid transmission was assessed by long-read sequencing. Data were analysed using bioinformatics tools and SNP-based phylogeny. RESULTS ESC-E carriage rate reached 34.5% (t0) and 52.9% (t6), and 15 workers were positive at both t0 and t6. Carbapenem resistance (blaOXA-181, blaOXA-204, blaNDM-5) was found in five workers at t0 and two at t6, while colistin resistance (mcr-1.1) was found in five workers at t0 and one at t6. Forty-seven different STs were identified, of which three STs were predominant (ST131, n = 9; ST10, n = 5; ST69, n = 5). One worker presented the same ESC-E clone at t0 and t6. Twelve different events of clonal transmission among individuals were exemplified while plasmid transmission was only shown once. CONCLUSIONS Our study revealed a high carriage rate of MDR E. coli (60.7%) and the emergence of CP and colistin resistance in the Lebanese community. Incidental and long-term ESC-E carriage was observed in 41.7% and 17.9% of the workers, respectively. The high clonal diversity suggests an important dynamic of acquisition and loss of MDR E. coli and limited plasmid spread.

Abstract
Poultry and poultry meat are important contributors to the global antimicrobial burden. Unregulated and illegal use of extended-spectrum cephalosporins (ESC) in this sector has long been identified as a major cause of massive spread of ESC-resistant Escherichia coli, and colistin usage is considered a main driver of plasmid-mediated mcr genes dissemination. In Lebanon, the first mcr-1-positive E. coli found in poultry dates back to 2015, followed by a few reports of mcr-1-positive E. coli in poultry, swine, humans, and the environment. On the contrary, a comprehensive picture of the population structure of mcr-1-positive E. coli and mcr-1-bearing plasmids carrying the mcr-1 gene using whole-genome analysis is largely lacking. This study reports the prevalence of mcr-1-positive E. coli in poultry originating from 32 farms across three Lebanese governorates and slaughtered in the same place. We report 27/32 (84.4%) mcr-1 positive farms, leading to a total of 84 non-duplicate E. coli collected, of which 62 presented the mcr-1 gene. Numerous associated resistances were identified, including to ESC through the presence of bla CTX-M or bla CMY genes. The mcr-1 gene was mostly carried by IncX4 (n = 36) and IncI2 (n = 24) plasmids, which are both known for their efficient transfer capacities. A high genetic diversity was detected, arguing for the lack of contamination during the slaughter process. ST744 and ST1011 were the most widely identified clones, which have been both regularly associated to mcr-1-carrying E. coli and to the poultry sector. The wide dissemination of colistin-resistance, coupled to resistances to ESC and numerous other molecules, should urge authorities to implement efficient guidelines for the use of antibiotics in the poultry sector in Lebanon.

Abstract
The main goal of this preliminary study was to quantify airborne particles and characterize the dominant cultivable bacterial species as well as some Gram-positive species, and their antibiotic resistance pattern, from environmental samples taken inside and outside of a dairy milking parlour. Sampling was performed over 2 days, in different seasons. The small viable particulate matter < 10 μm (bioaerosols) and cultivable bacteria reached their highest concentrations in the milking parlour. The majority of airborne bacteria in the milking parlour belonged to the genera Staphylococcus (41.9%) and Bacillus (20.9%). A total of 32 different bacterial species of Staphylococcus, Aerococcus, Bacillus, Pseudomonas, Serratia and Acinetobacter were identified. Many of these bacteria may be opportunistic pathogens, causing disease in humans or animals. We found low levels of acquired resistance to the antibiotics commonly used in human or animal infections caused by these opportunistic bacteria. More specifically, resistance to tetracyclines (13.4%), penicillin G (13.4%) and macrolides (7.5%) was identified in Staphylococcus sp. as was a methicillin-resistant S. hominis and resistance to spiramycin (n = 1), lincomycin (n = 1) and streptomycin (n = 2) in Aerococcus sp. An assessment of the occupational risk run by dairy farmers for contracting infections after long- or short-term exposure to micro-organisms requires further studies on the concentration of opportunistic pathogenic bacteria in dairy farm environments.

Abstract
Wildlife has recently been pinpointed as one of the drivers of dissemination of genes conferring resistances to clinically important antimicrobials. The presence of both extended-spectrum beta-lactamase- (ESBL) and carbapenemase-encoding genes has notably been reported in wild birds, that can act as sentinels of antimicrobial resistance (AMR) contamination but also as long-distance spreaders in case of migratory birds. Here, 424 wild birds brought to a rescue center in France were sampled over a 6-month period. These birds encompassed 62 different sedentary or migratory species. A further 16 wild mammals present in the center were also investigated. No carbapenemase-producer was found, but we identified a surprisingly high proportion (24.1%) of ESBL-positive isolates. A total of 144 non-duplicate isolates were collected, including Escherichia coli (n = 88), Enterobacter cloacae (n = 51), and Citrobacter freundii (n = 5), of which 123 carried the blaCTX–M–9 gene. PFGE, phylogroup, and MLST revealed the presence of a limited number of ESBL-positive clones circulating in these animals, all presenting multiple associated resistances. Next-generation sequencing on a subset of isolates, followed by Southern blot hybridization, showed the wide dissemination of an IncHI2/ST1 plasmid carrying the blaCTX–M–9, blaSHV–12 and mcr-9 genes. In all, our results undoubtedly reflect cross transmissions of ESC-resistance (ESC-R) Enterobacteriaceae within the rescue center – similarly to nosocomial spreads observed at hospital, rather than the true bacterial flora of birds. We also showed that the spread of ESC-R in this rescue center did not only rely on clonal but also on a highly successful plasmidic transmission. Since most animals are intended to get back to nature after a few days or weeks, this is obviously an issue with regard to ESBL dissemination in natural environments.

Abstract
AIMS The goal was to explore the effects of subinhibitory concentration (SIC) (0·5 MIC = 20 µg l-1 ) of ciprofloxacin on the transcriptome of enterohaemorrhagic Escherichia coli O26:H11 isolate by 60 minutes of exposure. MATERIALS AND RESULTS We used a combination of comparative genomic and transcriptomic (RNAseq) analyses. The whole genome of the E. coli O26:H11 #30934 strain of bovine origin was sequenced and assembled. This genome was next used as reference for the differential gene expression analysis. A whole-genome-based analysis of 36 publicly available E. coli O26:H11 genomes was performed to define the core and the accessory transcriptome of E. coli O26:H11. Using RNAseq and RT-qPCR analysis we observed overexpression of the SOS response and of T3SS effectors, together with the inhibition of specific motility-associated genes. Among the large set of transposases present, only three were activated, suggesting moderate transposition of genes with low doses of ciprofloxacin. Our results illustrated that transcriptional repressors, such as the CopG family protein, belonging to the core genome of E. coli O26:H11, are altered in response to fluoroquinolone exposure. The gene ontology enrichment analysis showed SIC of ciprofloxacin induced binding functions and catalytic activities, including mostly transferase and hydrolase proteins. The amino acid pathways involved in metabolic processes were significantly enhanced after the treatment. CONCLUSIONS Although the core genome of E. coli O26:H11 constituted only 54·5% of the whole genome, we demonstrated that most differentially expressed genes were associated with the core genome of E. coli O26:H11, and that effects on the mobile genetic element, phage, and plasmid-related genes were rare. SIGNIFICANCE AND IMPACT OF THE STUDY For the first time the effect of low dose of ciprofloxacin on the core transcriptome of E. coli O26:H11 was described. The effects on the main biological functions and protein classes including transcriptional regulators were illustrated.

Abstract
Escherichia coli is a ubiquitous commensal and pathogen that has also been recognized as a multi-sectoral indicator of antimicrobial resistance (AMR). Given that latter focus, such as on resistances to extended-spectrum cephalosporins (ESC) and carbapenems, the reported population structure of E. coli is generally biased toward resistant isolates, with sequence type (ST)131 being widely reported in humans, and ST410 and ST648 being reported in animals. In this study, we characterized 618 non-duplicate E. coli isolates collected throughout France independently of their resistance phenotype. The B2 phylogroup was over-represented (79.6%) and positively associated with the presence of numerous virulence factors (VFs), including those defining the extra-intestinal pathogenic E. coli isolates (presence of ≥2 VFs: papA, sfaS, focG, afaD, iutA, and kpsMTII) and those more specifically related to uropathogenic E. coli (cnf1, hlyD). The major STs associated with clinical isolates from dogs were by far the dog-associated ST372 (20.7%) and ST73 (20.1%), a lineage that had commonly been considered until now as human-associated. Resistance to ESC was found in 33 isolates (5.3%), along with one carbapenemase-producing isolate, and was mostly restricted to non-B2 isolates. In conclusion, the presence of virulent E. coli lineages may be the issue, rather than the presence of ESC-resistant isolates, and the risk of transmission of such virulent isolates to humans needs to be further studied.

Abstract
The Eurasian wild boar (Sus scrofa) is increasingly considered as a relevant actor in the epidemiology of animal tuberculosis (TB). Therefore, monitoring TB in this species is key when establishing comprehensive control schemes for this disease still present in Europe. No data are available on direct and indirect TB diagnostic methods in wild boars in epidemiological contexts where TB is endemic in cattle and detected in wild boars at low prevalence. We aimed to estimate and compare sensitivity and specificity values for bacterial culture, PCR and three commercial ELISAs, i.e. the TB ELISA-VK (using the bPPD antigen), INgezim TB Porcine and IDEXX M. bovis Ab Test (both using the MPB83 and MPB70 antigens), under field conditions in France. We used frequentist methods, with bacteriology as the gold standard, and a Bayesian formulation of the latent class analysis (LCA), without using a gold standard. Submandibular lymph nodes and sera from 495 wild boars hunter-harvested in three endemic areas (Aquitaine region, Côte d’Or region, and Corsica region) were collected between 2014 and 2016. Only eight individuals were positive for M. bovis by bacteriology (1.61%; CI95% 0.70–3.51%). The LCA method provided high specificities (99.2%; CI95% 98.2–99.8% for INgezim TB Porcine and 99.7%; CI95% 98.8–100% for IDEXX M. bovis Ab Test) and sensitivities (78.5%; CI95% 65.1–88.8% for INgezim TB Porcine and 83.9%; CI95% 58.9–97.2% for IDEXX M. bovis Ab Test) for both ELISAs using the MPB83 and MPB70 antigens. Bacterial culture showed limited sensitivity (42.8%; CI95% 19.0–70.6%), estimated as the probability of a positive result in an animal exposed to M. bovis. PCR and ELISA using the bPPD antigens demonstrated high specificities, and sensitivities intermediates between culture and the ELISAs using the MPB83 and MPB70 antigens. These results suggest that ELISA tests using the MPB83 and MPB70 antigens are useful to detect and monitor TB exposure of wild boar populations in field conditions in France.

Abstract
To evaluate the routine complement fixation test (CFT) used to detect Burkholderia mallei antibodies in equine sera, an interlaboratory proficiency test was held with 24 European laboratories, including 22 National Reference Laboratories for glanders. The panels sent to participants were composed of sera with or without B mallei antibodies. This study confirmed the reliability of CFT and highlighted its intralaboratory reproducibility. However, the sensitivity of glanders serodiagnosis and laboratory proficiency may be improved by standardising critical reagents, including antigens, and by developing a standard B mallei serum.

Abstract
The Eurasian wild boar (Sus scrofa) is increasingly considered as a relevant actor in the epidemiology of animal tuberculosis (TB). Therefore, monitoring TB in wild boar becomes a key tool for establishing comprehensive control schemes for this disease. To estimate the exposure of free living wild boar to Mycobacterium tuberculosis complex (MTC) in France, a bovine-purified protein derivative based ELISA was used to test 2,080 archived serum samples of hunter-harvested animals in 58 French “départements”. Two cut-off values were used for diagnostic interpretation: 0.2, recommended by the manufacturer (specificity: 96.43%; sensitivity: 72.6%), and 0.5 (specificity: 100%; sensitivity: 64%). During the same period, at the 0.2 cut-off, global true seroprevalence was 5.9% (IC95%: 4.3%-7.7%) and 76% of the sampled “départements” had seropositive wild boar, including seven cattle TB-free “départements. At the 0.5 cut-off, global true seroprevalence was 2.2% (IC95%: 1.5-3.2) and positive wild boar belonged to 21% of the “départements”. All but one of these positive “départements” had reported at least one cattle TB outbreak since 2000. A good consistence between seropositive wild boar and TB outbreaks in cattle was found, especially at the 0.5 cut-off value (the mean distance to the nearest cattle TB outbreak was 13km and 27km for seropositive and seronegative wild boar, respectively; P<0.05). The use of an ELISA to detect MTC antibodies in wild boar has permitted the description of the geographic distribution of MTC contact in wild boar in France. Our results suggest that the ELISA could be used as a first screening tool to conduct TB surveillance in wild boar at a population level. High-risk wild boar populations (e.g. overabundant) could be tested and if identified positive by ELISA they should be surveyed in detail by combining pathology and culture.

Abstract
Background Brucella ovis causes an infectious disease responsible for infertility and subsequent economic losses in sheep production. The standard serological test to detect B. ovis infection in rams is the complement fixation test (CFT), which has imperfect sensitivity and specificity in addition to technical drawbacks. Other available tests include the indirect enzyme-linked immunosorbent assays (I-ELISA) but no I-ELISA kit has been fully evaluated. The study aimed to compare an I-ELISA kit and the standard CFT. Our study was carried out on serum samples from 4599 rams from the South of France where the disease is enzootic. A Bayesian approach was used to estimate tests characteristics (diagnostic sensitivity, Se and diagnostic specificity, Sp). The tests were then studied together in order to optimise testing strategies to detect B. ovis. Results After optimising the cut-off values in order to avoid doubtful results without deteriorating the concordance between the results of the two tests, the I-ELISA appeared to be slightly more sensitive than CFT (Se I-ELISA = 0.917 [0.822; 0.992], 95% Credibility Interval (CrI) compared to Se CFT = 0.860 [0.740; 0.967], 95% CrI). However, CFT was slightly more specific than I-ELISA (Sp CFT = 0.988 [0.947; 1.0], 95% CrI) compared to Sp I-ELISA =0.952 [0.901; 1.0], 95% CrI). The tests were then associated with two different interpretation schemes. The series association increased the specificity of screening and could be used for pre-movement testing in rams from uninfected flocks. The parallel association increased sequence sensitivity, thus appearing more suitable for eradicating the disease in infected flocks. Conclusions The high sensitivity and acceptable specificity of this I-ELISA kit support its potential interest to avoid the limitations of CFT. The two tests could also be used together or combined with other diagnostic methods such as semen culture to improve the testing strategy. The choice of test sequence and interpretation criteria depends on the epidemiological context, screening objectives and the financial and practical constraints.

Abstract
Seclusion with or without restraint is a measure used to manage patients with challenging behaviours. Although controversial, the intervention remains poorly documented, especially in Canadian psychiatric hospitals. The purpose of this study is to assess the prevalence of the measure and identify any correlated demographic characteristics and psychiatric disorders. Episodes of seclusion with or without restraint were extracted from a computerized, hospital-based system introduced specifically to track such interventions. Of 2721 patients hospitalized during that time, 23.2% (n = 632) were secluded with or without restraint, and 17.5% (n = 476) were secluded with restraint. Younger age, schizophrenia or other psychosis, bipolar and personality disorder, and longer stay in hospital are predictors of an episode of seclusion with or without restraint. Younger age, bipolar and personality disorders and a longer stay in hospital are predictors of an episode of seclusion with restraint. For patients who spent longer in seclusion and under restraint, there is a positive association with longer stay in hospital. In this inpatient psychiatric facility, seclusion with or without restraint thus appears to be common. More research is warranted to better identify the principal factors associated with seclusion and restraint and help reduce resort to these measures.

Abstract
OBJECTIVES [corrected] This analysis estimated the gender-specific associations between work stress, major depression, anxiety disorders and any mental disorder, adjusting for the effects of demographic, socioeconomic, psychological and clinical variables. METHODS Data from the Canadian national mental health survey were used to examine the gender-specific relationships between work stress dimensions and mental disorders in the working population (n = 24,277). Mental disorders were assessed using a modified version of the World Mental Health - Composite International Diagnostic Interview. RESULTS In multivariate analysis, male workers who reported high demand and low control in the workplace were more likely to have had major depression (OR 1.74, 95% CI 1.12 to 2.69) and any depressive or anxiety disorders (OR 1.47, 95% CI 1.05 to 2.04) in the past 12 months. In women, high demand and low control was only associated with having any depressive or anxiety disorder (OR 1.39, 95% CI 1.05 to 1.84). Job insecurity was positively associated with major depression in men but not in women. Imbalance between work and family life was the strongest factor associated with having mental disorders, regardless of gender. CONCLUSIONS Policies improving the work environment may have positive effects on workers' mental health status. Imbalance between work and family life may be a stronger risk factor than work stress for mental disorders. Longitudinal studies incorporating important workplace health research models are needed to delineate causal relationships between work characteristics and mental disorders.

Abstract
This study investigated the relationship of emotional disturbance and pre- and postmigration environment to the scholastic achievement of adolescent refugees of very different cultural backgrounds. One hundred fifty-two Central American and Cambodian students in six Canadian high schools, as well as their parents, were interviewed to assess the students' emotional problems (using the Youth Self-Report and Child Behavior Checklist) and to determine the pre- and postmigration family environment. The findings indicated that the relationship between the emotional problems and scholastic achievement of teenaged refugees was tenuous. It was concluded that a connection between young refugees' symptomatology and their functional capacity should not be assumed. Nonetheless, certain pre- and postmigration variables, particularly trauma experienced in the homeland, seem to be associated with the academic achievement of some refugees.

Abstract
OBJECTIVE To compare Cambodian and Central American adolescent refugees to Quebec with their Quebec-born peers in regard to emotional and behavioural problems, feelings of competence, and risk-behaviour profiles, and to examine relations between emotional variables and living conditions in the 3 groups. METHOD The sample consisted of 76 Cambodian, 82 Central American and 67 Québécois youth living in the Montreal area. The teenagers' internalization and externalization symptoms were assessed using the Child Behaviour Checklist (CBCL) and the Youth Self-Report (YSR); the YSR also provided a measure of their feelings of competence. Risk behaviour was reported by the teenagers. The socioeconomic status of the teenagers' households was taken into account in multiple regression analyses conducted for each group. RESULTS The level of emotional and behavioural problems reported by teenagers was lowest in Central Americans and highest in Québécois; the latter group also reported more risk behaviours than did either refugee group. The socioeconomic status of the Cambodian and Central American refugee households was lower than that of the Québécois. Living conditions were not a major determinant of emotional distress in young Cambodians, but low annual income was associated with internalizing symptoms among Central American youth. The most powerful predictor of externalizing symptoms among the Québécois youth was having a single-parent household. CONCLUSION This study underscores the contrast between the living conditions of young Cambodian and Central American refugees to Quebec and those of Quebec-born youth. These refugees' precarious socioeconomic status is not accompanied by an increase in adolescents' emotional and behavioural problems.

Abstract
OBJECTIVE The main aim of this study was to investigate the effect of war-related trauma on the subsequent social adjustment and functioning of young Cambodian refugees. METHOD This longitudinal study of 67 young Cambodian refugees in Montreal interviewed in the first year of high school and then 2 years later examines a family's exposure to war related premigration trauma and its association with an adolescent's emotional and behavioral problems and social adjustment. Emotional and behavioral problems were assessed using the Youth Self-Report and an inventory of risk behavior. Social adjustment was assessed in terms of academic achievement, peer relations, and feeling of competence. RESULTS The trauma a family suffered before leaving their homeland and prior to the teenager's birth seems to play a protective role at various times in adolescence with regard to externalized symptoms, risk behavior, and school failure in boys, and foster positive social adjustment in girls. CONCLUSIONS These reactions may be understood as overcompensation by the children of the survivors of a massacre, to whom the implicit duty to succeed has been passed on. They suggest that a broader range of posttraumatic responses to war situations should be investigated and that trauma's dual nature as both burden and source of strength should be examined more closely.

Abstract
OBJECTIVE To compare the types and rates of psychiatric symptoms of young Central American and Cambodian refugees, as reported by both parents and children, and to examine parent-child agreement in reporting symptoms. METHOD Interviews were conducted with 123 children aged 8 to 12 years and 158 adolescents aged 12 to 16 years and their parents. Parents assessed psychiatric symptoms via the Child Behavior Checklist, the 8- to 12-year-olds responded to the Dominic, and the adolescents answered the Youth Self-Report. Means of Internalizing and Externalizing scores were compared on the basis of ethnic origin, parent's sex, and child's sex, as were the Spearman correlation coefficients of parents' and children's ratings. RESULTS The Cambodian parents reported few symptoms in their children, and the Central Americans reported almost as many symptoms as did parents in U.S. clinical samples. The Cambodian children reported less symptoms than the Central Americans, but the interethnic difference was not significant in the adolescents' self-reports. Parent-child agreement varied considerably by sex and ethnic origin of the informant. CONCLUSIONS The results underscore the need to involve multiple informants in assessing psychiatric symptoms of refugee children in spite of the difficulties inherent in field research with this population. They also show that data on multiple informants gathered from Western samples are not universally valid.

Abstract
Pre- and post-migration contexts of refugee children from Central America and Southeast Asia were compared. The results suggest that the culture of origin radically modulates the relationship between the pre-migration experience and the developing post-migration universe. In the case of the Central American children, the state-sponsored violence suffered in the country of origin is strongly associated with subsequent family conflicts, whereas in the case of the Southeast Asians, conflict is associated with an active social network in the community of origin, suggesting that there is a delicate balance between the support provided and the burden imposed by the extended family.

Abstract
The relationship between school performance and emotional problems was assessed in a general population sample of refugee children from Southeast Asia and Central America. Results suggested that learning difficulties and levels of academic achievement were associated with emotional problems in both groups but that, despite comparable academic records, remedial measures were more often prescribed for Central American children.

Abstract
Risk factors associated with women's reproductive life and sexual growth do not adequately predict cancer incidence of the breast, uterus and ovary. The heterogeneous worldwide distribution of these cancers could imply that some environmental and cultural risk factors are involved in their cancerogenesis. The few attempts made so far to unravel their spatial structures at a geographic scale facilitating the search for exogenous risk factors have proved inconclusive. This study reports the results of a spatial analysis of the cancer incidence rates for breast, cervix, endometrium and ovary among Community Health Departments (CHD) in Quebec using a spatial autocorrelation method. Correlograms built according to four definitions of the inter-CHDs distance indicate that breast and ovary incidence rates follow quite similar spatial gradients attesting to their etiologic affinity. They also suggest that the spatial distribution of endometrial cancer follows a gradient divergent from that of breast and ovary cancers, and that the CHDs' spatial scale does not suitably describe the distribution of cervical cancer. The demonstration of a structured spatial distribution for breast, endometrium and ovary cancers in Québec strengthen the hypothesis that cultural or environmental risk factors are involved in their etiology. But, the observed disparities in the spatial structure of these cancers imply that their etiologic specificity may be greater than their biologic bond would suggest.
