prevalence and pathogenic potential of campylobacter isolates from free-living, human-commensal american crows.recent studies have suggested a potential role for wild birds in zoonotic transmission of campylobacter jejuni, the leading cause of gastroenteritis in humans worldwide. in this study, we detected campylobacter spp. in 66.9% (85/127) of free-ranging american crows (corvus brachyrhyncos) sampled in the sacramento valley of california in 2012 and 2013. biochemical testing and sequence analysis of 16s rrna revealed that 93% of isolates (n = 70) were c. jejuni, with cytolethal distending toxin (cdt) ...201424375131
influence of host ecology and behavior on campylobacter jejuni prevalence and environmental contamination risk in a synanthropic wild bird species.campylobacter jejuni is a foodborne pathogen that often leads to human infections through the consumption of contaminated poultry. wild birds may play a role in the transmission of c. jejuni by acting as reservoir hosts. despite ample evidence that wild birds harbor c. jejuni, few studies have addressed the role of host ecology in transmission to domestic animals or humans. we tested the hypothesis that host social behavior and habitat play a major role in driving transmission risk. c. jejuni in ...201627260356
genomic comparison of campylobacter spp. and their potential for zoonotic transmission between birds, primates, and livestock.campylobacter is the leading cause of human gastroenteritis worldwide. wild birds, including american crows, are abundant in urban, suburban, and agricultural settings and are likely zoonotic vectors of campylobacter their proximity to humans and livestock increases the potential spreading of campylobacter via crows between the environment, livestock, and humans. however, no studies have definitively demonstrated that crows are a vector for pathogenic campylobacter we used genomics to evaluate t ...201627736787
