Campylobacter is a foodborne pathogen found in the gut of poultry and other animals, which thereby act as reservoirs for human infection. Campylobacter produces various virulence factors which contribute to the establishment of disease. The aim of this study was to detect virulence genes in Campylobacter isolated from chicken faeces. A total of 408 poultry cloacal samples were analysed through culture, PCR and DNA sequencing. Campylobacter were detected in 24 (5.9 %) of the samples, of which 21 were C. jejuni while 3 were C. coli. The cdtB gene was detected in all Campylobacter isolates while cdtA and cdtC genes were detected in 20 (83.3%) and 18 (75.0%) of the isolates, respectively. The cadF gene was detected in 18 (85.7%) C. jejuni but not in C. coli. Eight genotypes designated G1 to G8 were detected among the isolates. Genotypes G1 and G7 possessed all three cdt genes, a potential for producing functionally active toxins. A large proportion (70.8%) of the isolates possessed both genes for toxin production and adhesion. The high prevalence of cdt and cadF genes in Campylobacter species in this study indicates the pathogenic potential of the isolates. There is a need to implement control measures to curb the spread of these virulent strains.

Introduction: There is a dearth of surveillance data on clinical Campylobacter in South Africa, particularly in the private healthcare environment. We investigated the prevalence of resistance to first-line antibiotics used to treat campylobacterioses in clinical Campylobacter isolates from a private pathology laboratory. Methodology: Identification of the Campylobacter specific genes were confirmed by PCR. Minimum inhibitory concentrations were determined using the broth micro-dilution method against macrolides (erythromycin, azithromycin), fluoroquinolones (ciprofloxacin, gatifloxacin) and tetracycline. Results: Seventy-two Campylobacter isolates were identified by PCR, with 54 (75%) being classified as C. jejuni and 18 (25%) as C. coli. Of these, 11 (20.4%) C. jejuni and six (33.3%) C. coli strains were resistant to ciprofloxacin and three (7.41%) C. jejuni and three (16.7%) C. coli strains were resistant to gatifloxacin. The number of C. jejuni strains resistant to erythromycin and azithromycin was 17 (31.5%) and 36 (50%) respectively, while the resistance of C. coli strains to erythromycin and azithromycin were seven (38.9%) and 14 (77.8%) respectively. Resistance to tetracycline was detected in 10 (55.6%) C. coli and 14 (25.9%) C. jejuni strains. Conclusion: In the light of these resistant profiles, the lack of a South African Campylobacter surveillance program is of concern. Relatively high prevalence of resistance in clinical isolates of C. jejuni and C. coli to the fluoroquinolones, macrolides and tetracycline used in first line treatment is of great concern. The efficacy treating human campylobacteriosis should thus be revisited.

“…More worrisome, poultry are also a well-established source of food-borne campylobacteriosis in humans. In South Africa, 32.3% of the carcasses were reported to harbour Campylobacter , but no significant differences in contamination levels between fresh or frozen samples or within samples from butcheries, supermarkets or street vendors were detected (Mabote et al ., 2011 ). Surprisingly, more fresh carcasses from butcheries than from other outlets were contaminated with Salmonella , while a greater proportion of fresh carcasses from supermarkets were contaminated with Campylobacter (Mabote et al ., 2011 ).…”

Irrespective of the existence of potentially pathogenic organisms carried by animals, foods of animal origin remain the prime nutrition of humans world-wide. As such, food safety continues to be a global concern primarily to safeguard public health and to promote international trade. Application of integrated risk-based quality assurance procedures on-farm and at slaughterhouses plays a crucial role in controlling hazards associated with foods of animal origin. In the present paper we examine safety assurance systems and associated value chains for foods of animal origin based on historical audit results of some Southern African countries with thriving export trade in animal products, mainly to identify areas for improvement. Among the key deficiencies identified were: i) failure to keep pace with scientific advances related to the ever-changing food supply chain; ii) lack of effective national and regional intervention strategies to curtail pathogen transmission and evolution, notably the zoonotic Shiga toxin-producing Escherichia coli; and iii) a lack of effective methods to reduce contamination of foods of wildlife origin. The introduction of foods of wildlife origin for domestic consumption and export markets seriously compounds already existing conflicts in legislation governing food supply and safety. This analysis identifies gaps required to improve the safety of foods of wildlife origin.
