“…However, its implication in human diseases is rare and sporadic (49)(50)(51)(52)(53). C. hyointestinalis has also been reported in developed countries, more precisely in feces collected from dairy farms in Canada (19.3%), in Finland (10.8%) and from dairy goat farms in New Zealand (2%), and in 3.2% milk samples collected from dairy farms in Italy (45,47,48,54). C. hyointestinalis, as well as, other Campylobacter species were also isolated from wild boar in Japan and dogs in Canada (55,56).…”

High Campylobacter prevalence during early childhood has been associated with stunting and environmental enteric dysfunction (EED), especially in low resource settings. This study assessed the prevalence, diversity, abundance, and co-occurrence of Campylobacter spp. in stools from children in a rural area of eastern Ethiopia and their association with microbiome, diarrhea, and EED in children. Stool samples (n = 100) were collected from randomly selected children (age range: 360-498 days) in five kebeles in Haramaya District, Ethiopia. Diarrhea, compromised gut permeability, and gut inflammation were observed in 48, 45, and 57% of children, respectively. Campylobacter prevalence and species diversity were assessed using PCR and meta-total RNA sequencing (MeTRS). The prevalence of Campylobacter spp. in the children's stools was 50% (41-60%) by PCR and 88% (80-93.6%) by MeTRS (P < 0.01). Further, seven Campylobacter species (Campylobacter jejuni, Campylobacter upsaliensis, Campylobacter hyointestinalis, Campylobacter coli, Campylobacter sp. RM6137, uncultured Campylobacter sp., and Campylobacter sp. RM12175) were detected by MeTRS in at least 40% of children stools in high abundance (>1.76-log read per million per positive stool sample). Four clusters of Campylobacter species (5-12 species per cluster) co-occurred in the stool samples, suggesting that Campylobacter colonization of children may have occurred through multiple reservoirs or from a reservoir in which several Campylobacter species may co-inhabit. No associations between Campylobacter spp., EED, and diarrhea were detected in this cross-sectional study; however, characteristic microbiome profiles were identified based on the prevalence of Campylobacter spp., EED severity, and diarrhea. Forty-seven bacterial species were correlated with Campylobacter, and 13 of them also correlated with gut permeability, gut inflammation and/or EED severity. Forty-nine species not correlated with Campylobacter Terefe et al. Campylobacter and Microbiome in Stools were correlated with gut permeability, gut inflammation, EED severity and/or diarrhea. This study demonstrated that (1) in addition to C. jejuni and C. coli, multiple nonthermophilic Campylobacter spp. (i.e., Campylobacter hyointestinalis, Campylobacter fetus, and Campylobacter concisus) were frequently detected in the children's stools and (2) the Campylobacter, gut permeability, gut inflammation, EED severity, and diarrhea were associated with characteristic microbiome composition. Additional spatial and longitudinal studies are needed to identify environmental reservoirs and sources of infection of children with disparate Campylobacter species and to better define their associations with EED in low-income countries.

“…in feces thereby contaminating the farms environment, which can be the source of Campylobacter to the wild birds. According to numerous studies in different animal farms, such as pigs (Thakur and Gebreyes, 2010;Carrique-Mas et al, 2014), cattle (Sanad et al, 2011), sheep (Salihu et al, 2009), goats (Rapp and Ross, 2012) and poultry (Hermans et al, 2012) they showed that these farm animals play an important role in contamination of the environment.…”

Aims: Campylobacter is a major cause of gastroenteritis in humans worldwide, particularly in developed countries and is reported to show an increased trend in antibiotic resistance. The purpose of this study was to determine the occurrence of Campylobacter in wild birds, poultry and in poultry environments in Selangor, Malaysia as well as to determine the rate of antibiotic resistance among Campylobacter isolates from poultry and wild birds. Methodology and results: The wild birds were trapped near poultry farm areas and in open areas which were more than 5 km away from poultry farms (refered to as open environment). Of 57 wild birds trapped near the farm environment, 17.5% were positive for Campylobacter and out of these, 90% were Campylobacter jejuni. Of a total of 77 birds in the open environment, 22.1% were positive for Campylobacter and of these 88.7% were C. jejuni. The poultry farms consisted of 3 chicken and 2 duck farms. About 60% of the chickens and 44.8% of the ducks were positive for Campylobacter of which 80% were C. jejuni, while 20% were Campylobacter coli. The Campylobacter isolates were subjected to antibiotic susceptibility test using disk diffusion method against 12 antibiotics. All the isolates (100%) from wild birds around poultry houses were resistant to at least one antibiotic. Conclusion, significance and impact of study: The findings showed 93% of the isolates from wild birds were resistant to at least two antibiotics. Campylobacter isolates from poultry in the farms were resistant to at least one antibiotic. The antibiotic resistant Campylobacter is of public health importance.

“…A total of 730 samples comprising of poultry caeca (210), poultry meat (111) along with faeces of poultry (180), goat (26), sheep (23), pigs (78), calves (20) and humans (82) were collected from Pantnagar and nearby areas (Haldwani and Bareilly). All the samples were collected in sterile sample collection vials (Tarsons) and brought in ice packs to the laboratory where they were processed immediately for the isolation of Campylobacter spp.…”
