Prevalence and antimicrobial resistance of Campylobacter jejuni and C. coli identified in a slaughterhouse in Argentina. Curr Res Food Sci 2022; 5:590-597. [PMID: 35340997 PMCID: PMC8943338 DOI: 10.1016/j.crfs.2022.03.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2021] [Revised: 03/04/2022] [Accepted: 03/08/2022] [Indexed: 11/21/2022] Open
Abstract
The aim of this study was to evaluate the percentage of Campylobacter (C. jejuni and C. coli) from samples collected at the slaughterhouse to describe the prevalence of resistance to selected antimicrobials, and to characterize the genetic determinants. In total, from 333 samples analyzed, 31% were positive for Campylobacter. More positive samples were detected before the chiller (46%) than after the chiller (16%). C. coli (59%) was more prevalent than C. jejuni (41%). Antimicrobial resistance differences between C. jejuni and C. coli were found (p < 0.001). Multidrug resistance was found in 72% of C. coli isolates and 69% of C. jejuni isolates (p < 0.001). Most C. jejuni isolates (57%) had the three genes of the cmeABC efflux pump. The tet(O) gene and resistance-associated point mutations within both the gyrA and 23S rRNA genes were detected in 100% of C. coli isolates. On the other hand, C. jejuni only had more prevalence of the blaOXA-61 gene than C. coli (p < 0.001), and most of the C. jejuni isolates (70–80%) had the tet(O) and gyrA point mutation. These results could contribute to knowledge about the status of thermotolerant Campylobacter resistant to antimicrobials isolated from food animals in Argentina and to develop an antimicrobial resistance surveillance system. From samples analyzed, 31% were positive for Campylobacter. More positive samples were detected before the chiller (46%) than after it (16%). Multidrug resistance was found in 72% of C. coli isolates and 69% of C. jejuni isolates. The tet(O) gene was detected in 100% of the tetracycline-, resistantC. coliisolates. C.jejuni only had more prevalence of the blaOXA-61 gene than C. coli (p < 0.001).

Molecular epidemiology of Campylobacter jejuni isolates from the broiler production chain: first report of MLST profiles in Argentina. Rev Argent Microbiol 2020; 53:59-63. [PMID: 32736818 DOI: 10.1016/j.ram.2020.06.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Revised: 02/26/2020] [Accepted: 06/16/2020] [Indexed: 11/24/2022] Open
Abstract
Campylobacter jejuni is an important foodborne pathogen with global distribution. We describe a genotyping study of a collection of C. jejuni (n=137) isolated from different broiler farms and from multiple sites along the processing line in a slaughterhouse in Argentina during 2011, 2012 and 2015. The isolates were genotyped using pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). Based on the PFGE results, the isolates were grouped into 26 pulsotypes. Subsequently, the isolates representing these 26 pulsotypes were chosen for MLST genotyping, which identified 16 different sequence types (STs) and 6 clonal complexes (CCs) (21, 45, 48, 353, 354, 446). Several of the STs (n=7) have not been previously reported in the PubMLST.org database. The most prevalent CCs were 21, 45 (both associated with human campylobacteriosis worldwide) and 353. This study showed high genetic diversity among C. jejuni in the broiler production environment in Argentina with novel MLST genotypes.

Abstract
We studied and compared the prevalence of Campylobacter jejuni and Campylobacter coli in chicken carcasses from conventional and kosher broiler abattoirs and retail stores. The prevalence of thermotolerant Campylobacter-positive carcasses was 94.0 (kosher) and 32.0% (conventional) (p<0.0001), while the prevalence of samples contaminated with C. jejuni, C. coli and simultaneously with both species was 36.0, 2.0 and 56.0% (kosher) and 26.0, 4.0 and 2.0% (conventional) (p<0.0001), respectively. Samples of chicken carcasses (n=25) and food contact surfaces (tables, n=25; knives, n=25) from 25 retails were collected and risk quantification was performed. Retails were categorized as high-risk (n=11), moderate-risk (n=11) and low-risk (n=3). Nineteen (76.0%) carcasses, 20 (80.0%) tables and 18 (72.0%) knives were Campylobacter-positive. Retails and abattoirs proved to be sources of carcass contamination with Campylobacter spp. Carcasses from kosher abattoirs were mostly contaminated with Campylobacter spp., whereas C. coli was the most prevalent species isolated from carcasses in retail stores.

Res Vet Sci 2020; 132:69-77. [PMID: 32521281 DOI: 10.1016/j.rvsc.2020.05.017] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2018] [Revised: 03/25/2020] [Accepted: 05/20/2020] [Indexed: 12/21/2022]
Abstract
The objective of this meta-analysis was to summarize available information on the prevalence of thermotolerant Campylobacter in different animal food products. A number of multilevel random-effect meta-analysis models were fitted to estimate mean prevalence of thermotolerant Campylobacter and to compare them among animal food products (cattle, pigs, broiler, hen, goat, sheep). The mean prevalence of Campylobacter spp. in animal food products was 29.6% (95% CI 27.6%-31%), and the mean prevalence of C. jejuni and C. coli were 19.3% and 9.7%, respectively. The prevalence of Campylobacter spp. was higher in products whose sources were broiler meat (p-estimate = 47.8%; 95% CI 44.9%-50.6%). C. jejuni was mainly observed in broiler meat where prevalence estimate (p-estimate) was 33.7% (95% CI 30.7%-36.8%). On the other hand, C. coli was observed in broiler meat (p-estimate = 14.1%; 95% CI 12.3%-16.1%) and sheep meat (p-estimate = 11.0%; 95% CI 3.6%-29.1%). The animal food products with the lowest prevalence of Campylobacter spp. were milk and dairy products (p-estimate = 3.5%; 95% CI 1.8%-6.5%), eggs (p-estimate = 4.0%; 95% CI 1.4%-10.7%), sausage (p-estimate = 9.4%; 95% CI 3.3%-24.0%), This meta-analysis concluding that C. jejuni is the most prevalent species worldwide and broiler meat is the main contamination source for human. The prevalence of Campylobacter species has public health importance and national authorities must monitor the situation in each country with the aim to establish the appropriate risk management measures.

Abstract
The poultry meat supply chain is complex and therefore vulnerable to many potential contaminations that may occur. To ensure a safe product for the consumer, an efficient traceability system is required that enables a quick and efficient identification of the potential sources of contamination and proper implementation of mitigation actions. In this study, we explored the use of graph theory to construct a food supply chain network for the broiler meat supply chain in the Netherlands and tested it as a traceability system. To build the graph, we first identified the main actors in the supply chain such as broiler breeder farms, broiler farms, slaughterhouses, processors, and retailers. The capacity data of each supply chain actor, represented by its production or trade volumes, were gathered from various sources. The trade relationships between the supply chain actors were collected and the missing relationships were estimated using the gravity model. Once the network was modeled, we computed degree centrality and betweenness centrality to identify critical nodes in the network. In addition, we computed trade density to get insight into the complexity of sub-networks. We identified the critical nodes at each stage of the Dutch broiler meat supply chain and verified our results with a domain expert of the Dutch poultry industry and literature. The results showed that processors with own slaughtering facility were the most critical points in the broiler meat supply chain.

Abstract
Campylobacter is a public cause of globally identified human gastrointestinal disease. Nonetheless, in Iraq many sides of the epidemiology of campylobacteriosis and its impact on public health remain poorly understood. Hence, this study was taken to offer reference information on the prevalence rate, sensitivity to antibiotics and biotyping of Campylobacter in poultry products sold in the Wasit markets. A total of 85 samples were collected including chicken (n = 45) and turkey (n =40) meat were surveyed for isolation and identification. Thermotolerant Campylobacter was detected in 54 samples by which Campylobacter jejuni (C. jejuni) was recognized as a main species accounting for 37(68.5%),while Campylobacter coli (C. coli) had 17 (31.5%) of the positive samples. Highest resistance was perceived to oxacillin and tetracycline as (94.4% and 85.2%), respectively. While lowest rate of resistance, 29.6% was detected against gentamicin. Campylobacter coli isolates showed higher resistance rate than C. jejuni isolates towards the selected antibiotics. In addition, multiple drug resistance (MDR) to at least three antibiotics was detected in the vast majority (90.7%) of the experienced isolates. Forty- three (79.6%) of the isolates had multiple antibiotic resistance index (MAR-index) 0.4 and above. Results of biotyping showed that biotype I was the predominant biotype in the two species as 70.2 and 76.5 proportions in C. jejuni and C. coli, respectively. Our results proposed that the presence of Campylobacter in poultry with greater resistance to erythromycin and/ or ciprofloxacin triggers the public health alarm and accentuates the education of consumers on the quality and safety of such foods.

Comparative restriction enzyme mapping of Campylobacter jejuni isolates from turkeys and broilers based on flaA flagellar gene using HpyF3I endonuclease. Folia Microbiol (Praha) 2018; 64:189-195.

Abstract
Turkeys and broilers have been identified as important reservoirs for Campylobacter jejuni which is of public health significance. The evaluation of the genotypes among C. jejuni strains within different reservoirs is critical for our understanding of the epidemiology of this infectious agent. The present study aimed to compare the genetic diversity and differences of C. jejuni isolates from turkeys and broilers using flagellin PCR-RFLP typing (flaA typing) technique, in terms of the ease of use and discriminatory power. Sixty C. jejuni isolates were detected biochemically and confirmed by duplex-PCR from turkeys and broilers (30 strains from each bird species). Then, a flaA gene fragment (1725 bp) of C. jejuni isolates was amplified and amplicons were digested with HpyF3I enzyme. Restriction analysis by HpyF3I gave four different flaA patterns (H1, H2, H3, H4) among all tested C. jejuni isolates. In broiler isolates, all four patterns were observed but in turkey isolates, only H2 and H4 patterns were present. The results clearly demonstrated that distribution of the flaA typing patterns differed depending on the host species (broiler/turkey). H1 and H3 flaA types are more prevalent in broiler than turkey isolates, while H2 type is significantly more prevalent within isolates from turkey (p < 0.05). The flaA typing technique by digestion with HpyF3I enzyme can almost give us a clue to the source of infection in local outbreaks.

Abstract
The objective of this study was to investigate a clonal relationship among thermotolerant Campylobacter spp. isolates from different stages of the poultry meat supply chain in Argentina. A total of 128 thermotolerant Campylobacter spp. (89 C. jejuni and 39 C. coli) isolates from six poultry meat chains were examined. These isolates were from: a) hens from breeder flocks, b) chickens on the farm (at ages 1 wk and 5 wk), c) chicken carcasses in the slaughterhouse, and d) chicken carcasses in the retail market. Chickens sampled along each food chain were from the same batch. Campylobacter spp. isolates were analyzed using pulsed-field gel electrophoresis to compare different profiles according to the source. Clustering of C. jejuni isolates resulted in 17 profiles, with four predominant genotypes and many small profiles with just a few isolates or unique patterns, showing a very high degree of heterogeneity among the C. jejuni isolates. Some clusters included isolates from different stages within the same chain, which would indicate a spread of strains along the same poultry meat chain. Moreover, twenty-two strains of C. coli clustered in seven groups and the remaining 17 isolates exhibited unique profiles. Evidence for transmission of thermotolerant Campylobacter spp. through the food chain and cross contamination in the slaughterhouses were obtained. This collective evidence should be considered as the scientific basis to implement risk management measures to protect the public health.

Abstract
Thermotolerant Campylobacter spp. are a major cause of foodborne gastrointestinal infections worldwide. The linkage of human campylobacteriosis and poultry has been widely described. In this study we aimed to investigate the prevalence, antimicrobial resistance and genetic diversity of C. coli and C. jejuni in broilers from Ecuador. Caecal content from 379 randomly selected broiler batches originating from 115 farms were collected from 6 slaughterhouses located in the province of Pichincha during 1 year. Microbiological isolation was performed by direct plating on mCCDA agar. Identification of Campylobacter species was done by PCR. Minimum inhibitory concentration (MIC) values for gentamicin, ciprofloxacin, nalidixic acid, tetracycline, streptomycin, and erythromycin were obtained. Genetic variation was assessed by RFLP-flaA typing and Multilocus Sequence Typing (MLST) of selected isolates. Prevalence at batch level was 64.1%. Of the positive batches 68.7% were positive for C. coli, 18.9% for C. jejuni, and 12.4% for C. coli and C. jejuni. Resistance rates above 67% were shown for tetracycline, ciprofloxacin, and nalidixic acid. The resistance pattern tetracycline, ciprofloxin, and nalidixic acid was the dominant one in both Campylobacter species. RFLP-flaA typing analysis showed that C. coli and C. jejuni strains belonged to 38 and 26 profiles respectively. On the other hand MLST typing revealed that C. coli except one strain belonged to CC-828, while C. jejuni except 2 strains belonged to 12 assigned clonal complexes (CCs). Furthermore 4 new sequence types (STs) for both species were described, whereby 2 new STs for C. coli were based on new allele sequences. Further research is necessary to estimate the impact of the slaughter of Campylobacter positive broiler batches on the contamination level of carcasses in slaughterhouses and at retail in Ecuador.

Abstract
Avian hosts constitute a natural reservoir for thermophilic Campylobacter species, primarily Campylobacter jejuni and Campylobacter coli, and poultry flocks are frequently colonized in the intestinal tract with high numbers of the organisms. Prevalence rates in poultry, especially in slaughter-age broiler flocks, could reach as high as 100% on some farms. Despite the extensive colonization, Campylobacter is essentially a commensal in birds, although limited evidence has implicated the organism as a poultry pathogen. Although Campylobacter is insignificant for poultry health, it is a leading cause of food-borne gastroenteritis in humans worldwide, and contaminated poultry meat is recognized as the main source for human exposure. Therefore, considerable research efforts have been devoted to the development of interventions to diminish Campylobacter contamination in poultry, with the intention to reduce the burden of food-borne illnesses. During the past decade, significant advance has been made in understanding Campylobacter in poultry. This review summarizes the current knowledge with an emphasis on ecology, antibiotic resistance, and potential pre- and postharvest interventions.
