“…There is no such earlier data concerning pig and cattle samples, thus, it is not possible to compare the present results. However, the studies performed in other countries showed that such food producing animals at the slaughterhouse level were also often positive for Campylobacter, although the percentage of such samples was lower than identified during the present survey, and 81 (26.0%) samples out of 311 tested were positive (2,8,19). Biasi et al (2) demonstrated that 18.9% of pig carcasses were Campylobacter-positive (37 samples tested), whereas in Belgium 17% of 383 similar samples were contaminated (8).…”

A total of 2668 swabs from poultry (n = 2166), pig (n = 311), and cattle (n = 191) carcasses were collected in slaughterhouses all over Poland and tested for the presence of Campylobacter. It was found that 1319 (49.4%) of them were contaminated with these bacteria. The percentages of the positive samples were different in each year of the study and the highest proportion of Campylobacter contaminated samples occurred in 2009, when 64.1% of investigated carcasses were positive. On the other hand, the lowest prevalence of Campylobacter was observed in 2013, in the last year of the survey. In all kind of carcass samples both C. jejuni and C. coli were identified, although the pork meat was more contaminated with C. coli (75.3% of positive samples) than with C. jejuni (24.7%), whereas poultry was nearly equally positive for C. jejuni and C. coli (50.6% and 49.4% respectively). The analysis of seasonal contamination of the carcasses revealed that more positive results were found during the second half of year than between January and June. The prevalence of Campylobacter showed that in all provinces, except one (Pomorskie), the mean percentage of the positive samples was above 40%. The most contaminated samples were identified in Lubelskie (69.3%) and Zachodniopomorskie (66.3%) regions. The obtained results showed that slaughtered animals in Poland, especially broilers, were often contaminated with Campylobacter, either C. jejuni or C. coli.

“…Similar results were obtained by Inglis et al (2004), who identified less than 1% of Campylobacter ciprofloxacin-resistant strains of cattle origin. In general, antibiotic resistance, including MAR, in Campylobacter recovered from these food-producing animals is much less frequent than in those isolated from poultry and pigs (Englen et al 2007, Rozynek et al 2008, Szygalski Biasi et al 2011. However, in the present study most of the multi-resistant isolates were of C. coli and they were predominantly found in pigs.…”

“…On the other hand, cattle, and to a lesser extent pigs, are carriers of Campylobacter bacteria; however, there is little information concerning the contamination of their carcasses at the slaughterhouse level (Bae et al 2007, Englen et al 2007). As described by many authors, pigs carry a higher proportion of C. coli than C. jejuni; however, the carcasses are not as frequently contaminated with these bacteria as compared to poultry (Qin et al 2011, Szygalski Biasi et al 2011, Quintana-Hayashi and Thakur 2012. Recently, we have shown that bovine hides and carcasses tested in Poland at the slaughterhouse level were positive for Campylobacter at 25.6% and 2.7%, respectively (Wieczorek et al 2013).…”

“…On the other hand, Ghafir et al (2008) reported 17% of pig carcasses positive for Campylobacter tested from 1997 to 1999 in Belgium. Recently, Szygalski Biasi et al (2011) identified a high level of swine Campylobacter-positive carcasses (18.9%) but only 37 animals were investigated. A broader investigation performed in Alberta, Canada with 1,070 pork carcasses sampled at the slaughterhouse level with a swab method revealed that 8.8% of animals were positive for these bacteria (Bohaychuk et al 2011).…”

A total of 70 Campylobacter isolates recovered from 114 cattle and 177 pig carcasses at the slaughterhouse level were characterized by the presence of 7 putative virulence genes and antimicrobial susceptibility using the microbroth dilution method and minimal inhibitory concentration (MIC). The prevalence of Campylobacter was 14.9% and 29.9% in cattle and pig samples, respectively. The majority of cattle carcasses were contaminated with C. jejuni (64.7%), whereas pig carcasses were mainly positive for C. coli (77.4%). Most of the strain, irrespective of origin, possessed at least one pathogenic gene marker tested, mainly flaA and cadF genes responsible for motility and adherence to host epithelial cells, respectively. Several isolates also possessed the cdtA and cdtB genes responsible for the production of cytolethal distending toxin. Antibiotic profiling showed that campylobacters were most frequently resistant to quinolones (nalidixic acid and ciprofloxacin, total 57.1% of isolates) followed by streptomycin (52.9%, only C. coli strains) and tetracycline (51.4%). Resistance to erythromycin was demonstrated only in 4 C. coli strains of pig origin. None of the isolates, irrespective of origin, was resistant to gentamycin. Multi-resistance patterns, defined as resistance to antimicrobials of at least two different classes, were observed among 65.4% of the isolates, mainly C. coli recovered from pig carcasses.

“…There is no published information on tetracycline-resistant Campylobacter from pigs in other Caribbean islands. Tetracycline resistance was 100% in pig Campylobacter in Brazil (Biasi et al, 2011). On the other hand, of seven C. coli isolates from pigs, five were resistant to erythromycin, but sensitive to tetracycline (Harrow et al, 2004).…”

Infections caused by Campylobacter species pose a severe threat to public health worldwide. However, in Grenada, the occurrence and characteristics of Campylobacter in food animals, including pigs, remain mostly unknown. In this study, we identified the sequence types (STs) of Campylobacter from young healthy pigs in Grenada and compared the results with previous studies in Grenada and other countries. Antimicrobial resistance patterns and diversity of the Campylobacter clones were evaluated. Ninety-nine Campylobacter isolates (97 Campylobacter coli and 2 Campylobacter jejuni) were analyzed by multilocus sequence typing. Eighteen previously reported STs and 13 novel STs were identified. Of the 18 previously reported STs, eight STs (ST-
