“…A higher prevalence rate has been reported by Giacoboni et al (9) in Japan (46.7%). In addition, lower prevalence rates have been found by Cabrita et al (3) in Portugal (19.5%), and Tresierra et al (15) in Peru. These results indicate, from the epidemiological stand point that intestinal carriage may be conditioned by the environment in each place.…”

“…Waterfowl have been reported as carriers of a wide range of pathogenic viral, bacterial, fungal, and parasitic microorganisms ( , ). Among bacterial pathogens, Campylobacter species have been frequently isolated from the feces and/or cloacal swabs of apparently healthy ducks and geese worldwide ( − ). Campylobacter jejuni , which is responsible for most Campylobacter infection in humans, was found to be more prevalent in the feces of waterfowl than C. coli and C. lari ( 12 , 15 − 17 , 24 , 26 , 27 ).…”

Campylobacters are emerging as one of the most significant causes of human infections worldwide, and the role that waterfowl and the aquatic environment have in the spread of disease is beginning to be elucidated. On a world scale campylobacters are possibly the major cause of gastrointestinal infections. Campylobacters are common commensals in the intestinal tract of many species of wild birds, including waterfowl. They are also widely distributed in aquatic environments where their origins may include waterfowl as well as sewage effluents and agricultural runoff. Campylobacters have marked seasonal trends. In temperate aquatic environments they peak during winter, whereas spring-summer is the peak period for human infection. Campylobacter species may survive, and remain potentially pathogenic, for long periods in aquatic environments. The utility of bacterial fecal indicators in predicting the presence of campylobacters in natural waters is questionable. Viable but nonculturable Campylobacter cells may occur, but whether they have any role in the generation of outbreaks of campylobacteriosis is unclear. The routine detection of Campylobacter spp. in avian feces and environmental waters largely relies on conventional culture methods, while the recognition of a particular species or strain is based on serotyping and increasingly on molecular methods. Thus, PCR combined with selective enrichment enhances the detection of campylobacters in water and feces, while DNA sequencing facilitates recognition of particular species and strains.

“…In a similar work, Tresierra-Ayala et al (30) isolated C. jejuni in 27% of the fecal samples of free range chickens, belonging to families of low social-economic level (Iquitos city, Peru). In another study, the same authors reported the presence of C. coli (17%) and C. lari (10%) in fecal samples of domestic chicken (29). Here in Brazil, Levi and Ricciardi (16) reported that C. jejuni was isolated in 64% of 168 fecal chicken samples, and Carvalho et al (4) found that 42% of the samples collected in poultry meat factories were contaminated with C. jejuni.…”

The aim of this study was to evaluate the occurrence of thermophilic Campylobacter species in broiler flocks from 26 small properties located near the campus of Federal University of Pelotas, RS, Brazil. A total of 404 chicken fecal samples were analyzed and after isolation, identification and biotyping was performed according to Lior´s scheme. Twenty one strains (5.2%) of Campylobacter jejuni biotype II were isolated from animals from seven properties (26.9%), with a variation from 3% to 34.6% among the positive properties. We also analyzed twelve C. jejuni isolates by polymerase chain reaction (PCR), using specific primers that generate a fragment of 402 pb. Our study allowed us to observe that chickens raised in non-industrial establishments without sanitary attention can harbour C. jejuni in their intestinal tract, and by doing so, they could be a serious health risk to humans.
