Abstract
The emergence and spread of methicillin-resistant Staphylococcus aureus (MRSA) in hospitals is a major global public health concern. The current study sought to characterize 25 MRSA clinical isolates collected in a Tunisian hospital from December 2015 to September 2016, with the genetic lineages, virulence factors, and antibiotic resistance mechanisms determined for these isolates. Three spa-types were detected: t037 (23 isolates), t932, and t2235 (one isolate each). Isolates were ascribed to agr I (n = 20), agr II (n = 1), with four nontypeable isolates. Depending on sequence type (ST), the 25 MRSA isolates were assigned to two clonal complexes (CC8 and CC5), with a predominance of the lineage ST239-CC8 (n = 24; 96%). All isolates belonging to CC8 had the SCCmec type III, while the unique CC5 isolate had SCCmec type IV. Antimicrobial susceptibility testing revealed high levels of resistance to aminoglycosides, tetracycline, ciprofloxacin and rifampicin for the majority of isolates belonging to the ST239-CC8 lineage. The ST149-CC5 isolate was susceptible to non-β-lactam antibiotics. One isolate harbored the tsst-1 gene (4%); however, lukS/LukF-PV, eta and etb genes were not detected. The MDR ST239-CC8 clone would seem to be widespread in this hospital. Therefore, a rigorous hygienic control system is urgently required.

Abstract
The O/ME-SA/Ind-2001d has been the main foot-and-mouth disease virus (FMDV) lineage responsible for FMD epidemics outside the Indian subcontinent from 2013 to 2017. In 2014, outbreaks caused by this FMDV lineage were reported in Maghreb, where it was initially detected in Algeria and Tunisia and later in Morocco. This was the first incursion of an FMDV type O of exotic origin in the Maghreb region after 14 years of absence. In this study, we report analyses of both VP1 and whole-genome sequences (WGSs) generated from 22 isolates collected in Algeria and Tunisia between 2014 and 2015. All the WGSs analysed showed a minimum pairwise identity of 98.9% at the nucleotide level and 99% at the amino acid level (FMDV coding region). All Tunisian sequences shared a single putative common ancestor closely related to FMDV strains circulating in Libya during 2013. Whereas sequences from Algeria suggest the country experienced two virus introductions. The first introduction is represented by strains circulating in 2014 which are closely related to those from Tunisia, the second one, of which the origin is more uncertain, includes strains collected in Algeria in 2015 that gave origin to the 2015 outbreak reported in Morocco. Overall, our results demonstrated that a unique introduction of O/Ind-2001d FMDV occurred in Maghreb through Tunisia presumably in 2014, and from then the virus spread into Algeria and later into Morocco.

Abstract
INTRODUCTION Ectopic breast tissue is present in 2-6% of women. Ectopic breast cancer represents an uncommon disease accounting for about 0.3% of all breast neoplasms, limiting the available evidence. Thus, we aim to report long-term outcomes in five cases treated at our institution. CASE SERIES Our Tunisian patients' median age was 48 years (33-60 years), and the median follow-up was 8 years (4-10 years). The ectopic breast tissue was located four times in the right axilla. The median tumor size was 25 mm (15-55 mm). Four of the patients underwent a wide local excision and axillary lymph node dissection. Three of those women had positive lymph nodes; thus, they received adjuvant chemotherapy, radiation therapy, and hormone therapy. The patient with a negative lymph node (case 5) had adjuvant radiation therapy and hormonal therapy. One of the patients (case 1) had a positive supraclavicular lymph node and received radiation therapy, chemotherapy, and hormonal therapy. The latter developed a locoregional relapse after 4 years and was treated with mastectomy and chemotherapy. One patient (case 4) had a distant metastasis after 2 years of follow-up and received chemotherapy. The three other patients were free of relapse during their follow-up period. CONCLUSION Primary axillary breast carcinoma is a rare entity. Despite the paucity of literature, our findings and authors' recommendations suggest that local excision can be performed safely with promising outcomes in this subset of patients.

Abstract
Abstract
Introduction
The sentinel lymph node (SLN) concept represents advancement in the management of the endometrial cancer (EC).
We aim to assess the performance of the SLN procedure; its positive predictive value (PPV) and negative predictive value (NPV); in stage I of EC (FIGO2009).
Method
A prospective study is conducted in our institution. We perform a double detection of the SLN (radiolabel Tc 99 microsulfur colloid and a color method using patent blue) followed by pelvic lymphadenectomy with or without paraaortic lymphadenectomy. A pelvic MRI is performed to determine myometrial invasion and nodal status. The injection of Tc 99m colloid occurs the day prior to surgery. The injection into the stroma of the cervix at the 3 and 9 o'clock positions was performed by an oncologist surgeon with the assistance of a nuclear medicine physician. Preoperative lymphoscintigraphy was obtained after 90-120 minutes. We inject into the cervical stroma 2cc of patent blue similar to the Tc99 injection. A gamma detecting probe is used to locate radioactive lymph nodes. The SLNs identified then are labelled as radioactive and/or blue. No frozen-section analysis was performed.
Results
For the pathological analysis of the SLN, Haematoxylin Eosin is used. If there is no metastasis detected, an ultra staging protocol using different anti-cytokeratines is conducted. Studies have shown that this approach is possible having satisfactory results when conducted by dedicated surgical, radiology and pathology team. We look forward to our outcomes to illustrate those results.

Abstract
Introduction : À l’heure actuelle, le retentissement des cancers utérins, ainsi que leur traitement sur l’image du corps, demeure un sujet peu étudié en Tunisie et souvent négligé aussi bien par les praticiens, les malades et leurs partenaires.
Méthodes : Il s’agit d’une étude transversale descriptive colligeant 100 patientes tunisiennes suivies à l’institut Salah- Azaïez pour un cancer de l’endomètre ou du col utérin confirmés histologiquement et non métastatiques, avec un recul supérieur à six mois. Nous avons utilisé l’échelle Body Image Scale (BIS) et Female Sexual Function Index (FSFI). Nous avons collecté les antécédents personnels et familiaux, et différentes données sociodémographiques des patientes.
Résultats : Dans notre étude, 40 % des patientes ont des troubles de l’image du corps. La moyenne du score BIS était de 12,03 avec des extrêmes allant de 0 à 30 avec un écarttype de 7,88. En analyse univariée, l’absence du soutien familial, l’altération de la relation de couple et de la relation sexuelle, la mauvaise tolérance de la chirurgie et la curiethérapie utérovaginale étaient significativement associées à l’altération de l’image corporelle. En analyse multivariée, le bas niveau socio-économique était le facteur indépendant protecteur du trouble de l’image du corps, et la dysfonction sexuelle était le facteur indépendant prédicteur de ce trouble.
Conclusions : Le manque de communication des patientes avec leur conjoint et avec l’équipe de soin constitue l’un des principaux obstacles lorsqu’il s’agit de reconnaître et de traiter ce problème. Des stratégies préventives visant à maintenir une image corporelle positive chez ces femmes devraient être entreprises.

Abstract
Over the last 20 years, Italy has experienced multiple incursions of different serotypes of Bluetongue virus (BTV), a Culicoides‐borne arbovirus, the causative agent of bluetongue (BT), a major disease of ruminants. The majority of these incursions originated from Northern Africa, likely because of wind‐blown dissemination of infected midges. Here, we report the first identification of BTV‐3 in Sardinia, Italy. BTV‐3 circulation was evidenced in sentinel animals located in the province of Sud Sardegna on September 19, 2018. Prototype strain BTV‐3 SAR2018 was isolated on cell culture. BTV‐3 SAR2018 sequence and partial sequences obtained by next‐generation sequencing from nucleic acids purified from the isolate and blood samples, respectively, were demonstrated to be almost identical (99–100% of nucleotide identity) to BTV‐3 TUN2016 identified in Tunisia in 2016 and 2017, a scenario already observed in past incursions of other BTV serotypes originating from Northern Africa.

Abstract
The aim of this work was the genetic characterization of cefotaxime-resistant enterobacteria from animals (53 samples), the surface water of rivers (17 samples), and wastewater treatment plants (43 samples) in Tunisia. A total of 48 (42.4%) cefotaxime-resistant isolates were recovered. An extended spectrum beta-lactamase (ESBL) phenotype with a positive double-disk synergy test (DDST) was exhibited by 34 (70.8%) and 14 (29.1%) isolates from water and animal origins, respectively. Isolates from water were identified as: Escherichia coli (n = 17), Hafnia spp. (n = 13), Citrobacter spp. (n = 1), Enterobacter cloacae (n = 1), Klebsiella pneumoniae (n = 1), and K. oxytoca (n = 1). Animal isolates were identified as: E. coli (n = 11), E. cloacae (n = 1), Hafnia spp. (n = 1), and K. pneumoniae (n = 1). PCR investigation of blaCTX-M, blaTEM, and blaSHV genes showed that amongst the 48 isolates with a positive DDST, 41 (87.5%) carried the blaCTX-M gene, 1 isolate harbored the blaSHV gene, and 1 isolate coharbored blaCTX-M with blaSHV genes. The class 1 and 2 integrons were detected in 27 (56.2%) and 1 (2%) isolates, respectively. Our study showed a significant occurrence of ESBL-producing enterobacteria in animals and aquatic environments with a predominance of blaCTX-M genes.

Abstract
Eighty percent of brain metastases (BM) are diagnosed in patients with known primary site of cancer. BM of unknown primary represents a difficult diagnosis. In up to 15% of patients with BM, the site of the primary tumor will not be detected despite investigations. The prognosis of this entity is very poor. We report here a case of a long survival of a patient with brain metastasis of unknown primary. The conclusion that can be drawn is that within BM of unknown primary exist patients with a very good prognosis that must be collected and published in order to base recommendations.

Abstract
The objective was to characterize Staphylococcus aureus isolated from two wastewater treatment plants (WWTPs) located in Tunis City (Tunisia), during the period 2014-2015. Genetic lineages, antibiotic resistance mechanisms and virulence factors were determined for the recovered isolates. S. aureus isolates were recovered from 12 of the 62 wastewater samples tested (19.35%), and one isolate/sample was characterized, all of them being methicillin-susceptible (MSSA). Six spa types (t587, t674, t224, t127, t701 and t1534) were found among the 12 isolates, and the spa-t587, associated with the new sequence type ST3245, was the most predominant one (7 isolates). The remaining isolates were assigned to five clonal complexes (CC5, CC97, CC1, CC6 and CC522) according to the sequence-type determined and/or the spa-type detected. S. aureus isolates were ascribed to agrI (n = 3), agrII (n = 7) and agrIII (n = 1); however, one isolate was non-typeable. S. aureus showed resistance to (number of isolates): penicillin (12), erythromycin (7), tetracycline (one) and clindamycin (one). Among the virulence factors investigated, only one isolate harboured the tst gene, encoding the TSST-1 (toxic shock syndrome toxin 1). Despite the low number of studied isolates, the present study reports the occurrence of both human- and animal-associated S. aureus clonal complexes in WWTPs in Tunisia.

Abstract
Staphylococcus aureus is a versatile bacterium, which can infect or colonize a variety of host species. The objective of this study was to characterize S. aureus isolates recovered from nasal swabs of 167 healthy ewes sampled from 12 farms in different areas of Tunisia during the period of 2014-2015. Genetic lineages, virulence factors and antibiotic resistance mechanisms were determined for recovered isolates. S. aureus was detected in 45 out of 167 tested samples (26.9%). All isolates were methicillin-susceptible (MSSA) and the majority of them were susceptible to tested antibiotics with few exceptions (% of resistance): penicillin (8.8), ciprofloxacin (4.4), and tobramycin or tetracycline (2.2, each). Twelve different spa types were detected (t15098, t15099, t1773, t3576, t1534, t5428, t3750, t5970 t254, t2883, t127 and t933), two of them were new (t15098 and t15099). S. aureus isolates were ascribed to agrI (n=23), agrII (n=1) and agrIII (n=20), and one was non-typeable. According to the sequence-type (ST) determined and/or the spa-type detected, the 45S. aureus isolates were assigned to six clonal complexes, with CC522 (44.4%) and CC130 (37.7%) being the most common lineages. Twenty-one (46.6%) and two (4.2%) isolates harbored the tst and eta genes encoding TSST-1 and ETA, respectively. In conclusion, nares of healthy ewes could be a reservoir of MSSA CC522 and CC130, lineages associated with TSST-1 and ETA that might represent a risk to human health.

Abstract
Since 1998, southern Europe has experienced multiple incursions of different serotypes and topotypes of Bluetongue virus, a vector-borne transmitted virus, the causative agent of Bluetongue (BT), a major disease of ruminants. Some of these incursions originated from northern Africa, likely because of wind-blown dissemination of infected midges. In this report, we describe the detection and whole genome characterization of a novel BTV-3 strain identified in a symptomatic sheep in Tunisia. Sequences were immediately deposited with the GenBank Database under Accession Nos KY432369-KY432378. Alert and preparedness are requested to face the next vector seasons in northern Africa and the potential incursion of this novel strain in southern Europe.

Abstract
Staphylococcus aureus is a major agent of bovine mastitis in dairy herds, causing economic losses in dairy industry worldwide. In addition, milk and milk-products contaminated by Staph. aureus can cause harmful human diseases. The aim of this study was to characterize Staph. aureus strains isolated from dairy farms in Tunisia. Bulk tank milk (n = 32) and individual cow milk (n = 130) samples were collected during the period of 2013-2014. Forty-three Staph. aureus isolates were recovered and typed by spa typing, 16S-23S rRNA intergenic spacer (RS-PCR) and multiplex PCRs for 22 virulence genes. Antimicrobial resistance was also investigated with a disc diffusion test. A selected subsample of 22 strains was additionally genotyped by multilocus sequence typing. Seventeen spa types were recovered, and t2421 (n = 10), t521 (n = 6) and t2112 (n = 5) were the most common. Fourteen different RS-PCR genotypes grouped into 11 clusters were detected in our study, with predominance of the RVI genotype (n = 24). Eight sequence types were identified and Clonal Complex 97, corresponding to RS-PCR cluster R, was the most common (n = 10), followed by CC1 (n = 4), CC15 (n = 3) and other four accounting for one or two strains. Different combinations of virulence genes were reported, and enterotoxin genes were present in few strains (seh, n = 4; sea, n = 2; sea and seh, n = 2; sec and sel, n = 2). The majority of strains were resistant only to penicillin; only one strain was found to be multiresistant and no methicillin-resistant Staph. aureus was demonstrated. Our study reported the isolation of CC97 from bovine milk in Tunisia for the first time and confirmed the relevance of this lineage in intramammary infection in cows. SIGNIFICANCE AND IMPACT OF THE STUDY This paper describes the characteristics of Staphylococcus aureus isolated from bulk tank and individual cow milk in Tunisia. All strains were genotyped by spa typing and RS-PCR, a method based on the amplification of the 16S-23S rRNA intergenic spacer region, and multiplex PCRs for 22 virulence genes. A selected subsample of strains was also genotyped by multilocus sequence typing. All strains were tested for antimicrobial resistance. Our study evidences a predominance of strains belonging to Clonal Complex 97. Methicillin-resistant strains were not detected, and overall low level of antimicrobial resistance was reported.

Abstract
Avian ESBL-producing Escherichia coli isolates have been increasingly reported worldwide. Animal to human dissemination, via food chain or direct contact, of these resistant bacteria has been reported. In Tunisia, little is known about avian ESBL- producing E. coli and further studies are needed. Seventeen ESBL-producing Escherichia coli isolates from poultry feces from two farms (Farm 1 and farm 2) in the North of Tunisia have been used in this study. Eleven of these isolates (from farm 1) have the same resistance profile to nalidixic acid, sulfonamides, streptomycin, tetracycline, and norfloxacine (intermediately resistant). Out of the six isolates recovered from farm 2, only one was co-resistant to tetracycline. All isolates, except one, harbored blaCTX-M-1 gene, and one strain co-harbored the blaTEM-1 gene. The genes tetA and tetB were carried, respectively, by 11 and 1 amongst the 12 tetracycline-resistant isolates. Sulfonamides resistance was encoded by sul1, sul2, and sul3 genes in 3, 17, and 5 isolates, respectively. The qnrB1 was detected in nine strains, one of which co-harbored qnrS1 gene. The search for the class 1 and 2 integrons by PCR showed that in farm 1, class 1 and 2 integrons were found in one and ten isolates, respectively. In farm 2, class 1 integron was found in only one isolate, class 2 was not detected. Only one gene cassette arrangement was demonstrated in the variable regions (VR) of the 10 int2-positive isolates: dfrA1- sat2-aadA1. The size of the VR of the class 1 integron was approximately 250 bp in one int1-positive isolate, whereas in the second isolate, no amplification was observed. All isolates of farm 1 belong to the phylogroup A (sub-group A0). However, different types of phylogroups in farm 2 were detected. Each of the phylogroups A1, B22, B23 was detected in one strain, while the D2 phylogroup was found in 3 isolates. The virulence genes iutA, fimH, and traT were detected in 3, 7, and 3 isolates, respectively. Two types of gene combination were detected: iutA+fimH+traT in 3 isolates and iutA+fimH in one isolate. The isolates recovered in farm 1 showed the same profile of PFGE macro-restriction, while isolates of farm 2 presented unrelated PFGE patterns. We conclude that these avian ESBL-producing E. coli isolates show homo- and heterogenic genetic background and that plasmids harboring ESBL genes could be involved in the dissemination of this resistance phenotype.

Abstract
In the last fifteen years, West Nile Virus (WNV) has dramatically expanded its geographic range and is now considered the most widespread arbovirus in the world. In Tunisia, West Nile Fever (WNF) outbreaks were reported in humans in 1997, 2003 and 2012. Usutu Virus (USUV), which is a 'new' emerging Flavivirus antigenically close to WNV, has never been reported in Tunisia. A serological investigation in 284 equids was conducted in 2012 in the southern west region of the country to assess the presence and prevalence of the WNV and USUV infection. Of the 284 samples tested by competitive enzyme-linked immunoassay, 129 were positive. Of these, 120 (42.3%) had WNV-specific neutralizing antibodies. The prevalence was significantly higher in areas closer to the oasis compared with that of the surrounding arid areas. Antibody titres against USUV were also reported in 10 equids. This was the first evidence of USUV circulation in Tunisia. Data recorded by this study indicate that WNV and USUV have circulated/are circulating in the region and that there is an urgent need to adapt the current surveillance programmes to this new scenario.

Abstract
Since 2000, several incursions of bluetongue virus (BTV) occurred in the Mediterranean Basin involving European and surrounding Countries. The Middle East represents one of the most important gateways for the access of BTV in Europe. Limited data on the BTV situation in this area are available. In this perspective, an epidemiological survey on the presence of BTV in Lebanon was conducted. Of the 181 serum samples tested, 97 (mean = 53.6%; 95% CI: 46.3-60.7) resulted positive when tested for the presence of BTV antibodies by c-ELISA, of these 42 (mean = 42%; 95% CI: 32.8-51.8) serum samples were from sheep and 55 (mean = 67.9%; 95% CI: 57.1-77.1) serum samples were from goats. Fourteen blood samples (14/110; mean = 12.7%; 95% CI: 7.8-20.3), 6 (6/66; mean = 9.1%; 95% CI: 4.4-18.5) from sheep and 8 (8/44; mean = 18.2%; 95% CI: 9.6-32.0) from goats, were positive by qRT-PCR. The results with serum-neutralization assay and typing performed by RT-PCR confirmed that six BTV serotypes are currently circulating in Lebanon, and these serotypes are as follows: 1, 4, 6, 8, 16 and 24. This study is the first report that confirms the presence and circulation of BTV in Lebanon.

Abstract
A duplex real-time reverse transcription-polymerase chain reaction (qRT-PCR) assay was developed for a simple and rapid diagnosis of Peste des petits ruminants (PPR). qRT-PCR primers and TaqMan probe were designed on a conserved region of nucleocapsid protein (Np) of PPR virus (PPRV) genome. An in vitro transcript of the target region was constructed and tested to determine analytical sensitivity. Commercial heterologous Armored RNA(®) was used as an internal positive control (IPC) for either RNA isolation or RT-PCR steps. The detection limit of the newly designed duplex real-time RT-PCR (qRT-PCR PPR_Np) was approximately 20 copies/μl with a 95% probability. No amplification signals were recorded when the qRT-PCR PPR_Np was applied to viruses closely related or clinically similar to PPRV- or to PPR-negative blood samples. A preliminary evaluation of the diagnostic performance was carried out by testing a group of 43 clinical specimens collected from distinct geographic areas of Africa and Middle East. qRT-PCR PPR_Np showed higher sensitivity than the conventional gel-based RT-PCR assays, which have been used as reference standards. Internal positive control made it possible to identify the occurrence of 5 false-negative results caused by the amplification failure, thus improving the accuracy of PPRV detection.

Abstract
This study involved 13 cases of patients fitted with intra-uterine contraceptive devices which migrated in the abdominal cavity. Laparoscopy enabled localization of the IUCD and full lesion assessment. It was removed by celio-surgery in all 13 cases. Difficulties encountered were due to parietoepiploic adhesions and IUCD impacted in the wall of the rectum.
