“…On the other hand, strains 3C and 6C were isolated from the same country region (Lubelskie voivodship) and at the same time but belong to different clonal groups -I and III, respectively. Previous studies have also shown that several Campylobacter genotypes can coexist among individual chickens (Schouls et al 2003) and that individual farms can be contaminated with multiple clones (Stanley and Jones 2003;Rivoal et al 2005).…”

Campylobacter infection is one of the most common enteric human diseases world-wide but the mechanism of Campylobacter pathogenicity has not been exactly explained yet. One of the main reasons is genotypic, hence phenotypic diversity of the bacterial isolates. The aim of the present study was to perform a molecular characterization of randomly selected C. jejuni and C. coli strains isolated from poultry faeces and carcasses in Poland. Several virulence gene markers were identified by polymerase chain reaction (PCR). Furthermore, genetic typing has also been used by the macrorestriction profiling with pulsed-field gel electrophoresis (PFGE). The results of the present study showed that all analyzed isolates of C. jejuni (n = 24) and C. coli (n = 24) contained the flaA and cadF sequences. On the other hand, the virB11 gene was present only in 6 of 48 (12.5%) of the analyzed isolates, whereas most of the strains contained the cdt genes. Other virulence gene iam linked to Campylobacter invasiveness was present in 34 of 48 (72.9%) strains. The restriction analysis of the whole genome digested with SmaI produced three main clonal groups designed as I, II (with two subgroups IIa and IIb), and III obtained by the comparison of macrorestriction profiling patterns. The results showed a poor correlation between Campylobacter profiles generated by a clonal molecular technique and the presence of virulence markers. Therefore, PCR detection of Campylobacter virulence markers can be utilized as a simple and rapid tool to discriminate stains recovered from different sources, especially when used in conjunction with the PFGE profile analysis as a complex strategy. These kinds of analyses had not been previously carried out in Poland and these results may generate more knowledge regarding the genetic diversity and molecular relationship of Campylobacter.

“…and assists in keeping this agent, since grow best in environments where temperatures around 42 °C (HORROCKS et al, 2008). Stern and Ro Bach (2003) evaluated the presence of Campylobacter spp. in broiler carcasses in North Georgia, and compared the results obtained in 1995 and 2001, obtaining a lower bacterial count in the collections of 2001, which was attributed to the implementation of the Hazard Analysis System and Critical Control industry (HACCP ).…”

Campylobacteriosis: an emerging zoonosis, underdiagnosed and underreported by public health agencies in Brazil

ABSTRACT:The infection by Campylobacter spp. constitutes a zoonosis of worldwide distribution, with serious repercussions for public health and a significant socio-economic impact. The Campylobacter species that most often are implicated in outbreaks of gastrointestinal disease are C. jejuni and C. coli. Both are recognized as the most important and with greater pathogenic potential from the viewpoint of food safety. This review aims to clarify and discuss, based on literature, the epidemiology of Campylobacter spp. and the main challenges in their control, to assist in better understanding of the risk posed to human health. Due to the difficulty of isolating and cultivating of Campylobacter spp., the high cost and not mandatory, laboratory diagnosis by traditional cultivation techniques is not widely used in Brazil, resulting in lack of accurate data on the occurrence of the disease in the country. This factor has been identified as responsible for underdiagnosing and underreporting of the disease, which means that data on contamination of animal products or outbreaks are not statements of actual national situation. The epidemiology of Campylobacter spp. is considered complex presenting multiple determinants in the spread of this microorganism. Chickens are important reservoirs of Campylobacter sp. and the main target of control measures, however, other vehicles of transmission, such as raw cow milk, drinking water and other foods of animal origin must also be considered in the set of measures to be taken to control disease. The infection by Campylobacter spp. cause gastroenteritis in humans and occurred by oral contact with infected animals. In fact, are pets or production and food consumption, the most important pathways. The clinical manifestations of the disease can be from mild to severe symptoms, including watery diarrhea, sometimes with blood, abdominal pain, fever, headache and nausea. Sometimes the infection can get complications after the diarrhea stops and starts a progressive paralysis that can result in respiratory failure and severe neurological dysfunction and may even lead to death. The occurrence of campylobacteriosi's outbreaks should be mandatory to the authorities of surveillance, to provide an investigation of common sources and transmission control through preventive measures , thereby minimizing the potential risks to human health.

“…isolation from the fecal and bile samples of ruminants in these reports are relatively high, i.e., 4%-91% from fecal samples and 16%-97% from bile samples. Variables such as herd size; type, season, and age of the animal; sample site; sample frequency; isolation method; geography; and diet and husbandry practices have been suggested as reasons for the differences in rates of isolation [14,24,25]. Our present data demonstrated that only 1.6% of the caecum samples and 1.0% of the bile samples from the buffaloes were positive for C. jejuni and C. fetus; no Campylobacter spp.…”

ABSTRACT. This is the first report regarding isolation of Campylobacter in caecum and bile samples obtained from ruminants in Vientiane, Lao PDR. Campylobacter was isolated from 3 (1.6%) of the 184 caecum samples and 1 (1.0%) of the 100 bile samples obtained from buffaloes. Three of the 4 isolates were determined to be C. jejuni, which was detected in 2 caecum samples and 1 bile sample; the other caecum sample contained C. fetus. Campylobacter was not isolated from any of the 82 cattle caecum samples. Our results suggest that cattle and buffaloes may not be important sources of Campylobacter food poisoning in Lao PDR.
