BACKGROUND: Food infections caused by Campylobacter are one of the gastrointestinal inflammations in humans is health and economic losses in the community is important. OBJECTIVES: To determine the prevalence of Campylobacter contamination in chicken skin samples of Urmia, using bacterial culture and polymerase chain reactions.                 METHODS: 80 samples of chicken skin from the Protein Gostare Sina slaughter house located in the city of Urmia in equal numbers in the winter and spring seasons were collected. The survival of Campylobacter after 24 hours in refrigerated conditions  was studied in samples. Positive samples were used for DNA extraction and PCR. To investigate the phylogenetic isolates, positive samples PCR were sequenced. RESULTS: 58/75% of chicken skin using bacterial cultures, Campylobacter were positive. The Results study the survival Campylobacter in cold conditions after 24 hours, showed that no significant decrease in the survival Campylobacter as well as contamination levels were significantly higher in spring than in winter, which may be due to the high temperature of environment that created the favorable conditions for Campylobacter. CONCLUSIONS: Chicken skin is the reservoir  of Campylobacter. This issue of public health care and control at all stages of production and supply of poultry products, also the transfer of it to other parts of poultry carcasses should be considered.

Campylobacter are the most common cause of food poisoning, which manifests itself in diarrhoea of varying severity. Additionally, because of the increasing number of people with immune deficiencies, more frequent serious complications of Campylobacter infections are being observed. The main source of infection is the consumption of contaminated poultry meat, which is a consequence of the insufficiency of current hygiene and biosecurity to control Campylobacter or eliminate it from the poultry food chain.

Campylobacteriosis is the most common human foodborne bacterial infection worldwide and is caused by bacteria of the Camplylobacter genus. The main source of these bacteria is poultry, but other food-producing animals such as pigs are also responsible for human infections. An increasing number of strains with resistance to fluoroquinolones and other antimicrobials such as macrolides were recently noted. The aim of the study was to investigate Campylobacter contamination of porcine carcasses and determine the antimicrobial resistance of the obtained isolates.

Campylobacter is the commonest reported bacterial cause of infectious intestinal disease. To study the epidemiology of Campylobacter infection among children, 100 stool samples along with patients anamnesis were collected from the clinical diarrheic reported to Enterology unit of Institute for child Health and centre for Children, Egmore, Chennai, Tamil Nadu between May 2013 to June 2013. Samples were subjected to traditional culture and modern PCR techniques, both of which revealed same results of 13% prevalence of Campylobacter sps (8% C.jejuni & 5% C.coli). Analyzing the patients anamnesis to study the epidemiological determinants, sex has a significance (P<0.05). Age and residential area have no significance and summer season and cross contamination could be probable determinants for the infection.

Poultry has been identified as a reservoir of foodborne enteric pathogens and antimicrobial resistant bacteria. The objective of this study was to describe and compare antimicrobial resistant isolates from an Ontario broiler chicken farm-level baseline project (2003 to 2004) to the Canadian Integrated Program for Antimicrobial Resistance Surveillance (CIPARS) Ontario abattoir and retail surveillance data from 2003, and to the most recent (2015) CIPARS Ontario chicken surveillance data in order to assess the impact of an industry-wide policy change in antimicrobial use. Ceftiofur resistance (TIO-R) prevalence in Salmonella decreased by 7% on farm between 2003 and 2004 and 2015. During the same timeframe, TIO-R E. coli prevalence decreased significantly by 16%, 11%, and 8% in farm, abattoir, and retail samples, respectively. Gentamicin resistant (GEN-R) E. coli, however, increased by 10% in farm and 15% in retail-derived isolates, and trimethoprim-sulfamethoxazole resistant (TMSm-R) E. coli increased significantly by 20%, 18%, and 5% in farm, abattoir, and retail isolates, respectively. Similarly, ciprofloxacin-resistant (CIP-R) Campylobacter spp. significantly increased in retail isolates by 11% and increased in farm (33%) and abattoir isolates (7%). The decrease in TIO-R Salmonella/E. coli in recent years is consistent with the timing of an industry-led intervention eliminating the preventive use of ceftiofur, a third generation cephalosporin and class of antimicrobials deemed critically important to human medicine. The rise in GEN-R and TMSm-R prevalence is indicative of recent shifts in antimicrobial use. Our study highlights the importance of integrated surveillance in detecting emerging trends and determining the efficacy of interventions to improve food safety.

Twenty-four isolates representing 6 species of Campylobacter were screened for plasmids. A large plasmid with an approximate molecular weight of 38 Mdal was detected in 5 C jejuni isolates originally recovered from diarrheic human beings, in one isolate of C coli recovered from diarrheic pigs, and in 1 isolate of C sputorum ssp mucosalis and 2 isolates of C hyointestinalis recovered from pigs with proliferative enteritis. One isolate of C coli and 1 isolate of C hyointestinalis contained an additional smaller plasmid with an approximate molecular weight of 1.6 Mdal; this plasmid was partially mapped by restriction endonuclease digestion. Fifteen Campylobacter isolates contained no detectable plasmids: 2 C coli, 2 C sputorum ssp mucosalis, 2 C fecalis, 1 C fetus ssp fetus, and 8 C hyointestinalis isolates. In summary, 37.5% of the Campylobacter isolates contained a 38-Mdal plasmid, with 8% having both 38 Mdal and 1.6-Mdal plasmids; 62.5% contained no detectable plasmids.
