“…Consistently with these observations, we detected V. cholerae in all our study species from different genera, but the prevalence in some species (e.g. 45% in the dunlin) was clearly higher than usually reported for wild birds (Hubálek 2004 , Ayala and Ogbunugafor 2023 ).…”

“…Vibrio cholerae is one of the most important bacterial pathogens in terms of public health, as it can be transmitted to humans, causing acute diarrheal illness (Lipp et al 2002 , Vezzulli et al 2010 ). Available information suggest that V. cholerae may be occasionally present in wild birds, mostly in species found in aquatic habitats, including shorebirds (Ogg et al 1989 , Hubálek 2004 , Ayala and Ogbunugafor 2023 ). Consistently with these observations, we detected V. cholerae in all our study species from different genera, but the prevalence in some species (e.g.…”

Long-distance host movements play a major regulatory role in shaping microbial communities of their digestive tract. Here, we studied gut microbiota composition during seasonal migration in five shorebird species (Charadriiformes) that use different migratory (stopover) habitats. Our analyses revealed significant interspecific variation in both composition and diversity of gut microbiome, but the effect of host identity was weak. A strong variation in gut microbiota was observed between coastal and inland (dam reservoir and river valley) stopover habitats within species. Comparisons between host age classes provided support for an increasing alpha diversity of gut microbiota during ontogeny and an age-related remodeling of microbiome composition. There was, however, no correlation between microbiome and diet composition across study species. Finally, we detected high prevalence of avian pathogens, which may cause zoonotic disease in humans (e.g. Vibrio cholerae) and we identified stopover habitat as one of the major axes of variation in the bacterial pathogen exposure risk in shorebirds. Our study not only sheds new light on ecological processes that shape avian gut microbiota, but also has implications for our better understanding of host-pathogen interface and the role of birds in long-distance transmission of pathogens.

“…Free-living birds may also be noticed as a significant vector of pathogenic Vibrio spp. Around 12 of the roughly 100 species in the genus Vibrio are related to clinical illnesses, such as cholera and vibriosis [ 100 ]. Authors found that the burden of disease in birds was most associated with V. cholerae , followed by V. metschnikovii and V. parahaemolyticus .…”

Birds that roam freely, particularly those that migrate, have the potential to carry a range of diseases that can be passed on to humans. The vast movement of these birds across diverse environments and urban areas can contribute to the spread of bacteria over long distances, impacting both human and animal populations. Stress, overcrowding, and human interaction can also play a role in the transmission of infectious diseases among birds and humans. Therefore, it is crucial to comprehend the intricate connections between birds, vectors, zoonotic pathogens, and the environment, especially given the increasing urbanization and emergence of zoonotic illnesses. This review aims to provide a systematic overview of the significance of avian species in transmitting bacterial pathogens that pose a risk to public health.

Atlantic salmon (Salmo salar) when exposed to heat stress have reduced voluntary feeding and exhibit changes in digesta consistency. This study was performed to determine what bacterial species occur and the overall bacterial abundance in the gut microbiome in heat stressed Atlantic salmon. For this Atlantic salmon in seawater tanks at 15°C were fed for 2 to 4 weeks. Tank temperatures were increased to 19°C until voluntary feeding abated at which point tank temperatures were cooled to 15°C for 4 weeks. At the end of each temperature phase the fish were stripped of feces and microbiome profiles were determined using 16S rRNA V1-V3 metabarcoding. The tank experiment was repeated three times in successive years. Vibrionaceae comprised most reads after the warm phase completed. The prominent levels of Vibrionaceae were accompanied by a large predominance of cast (sloughed intestinal mucosa) containing fecal samples. qPCR estimated Vibrionaceae cell populations increased 1.9-3.4 log units/g after the warm phase but and slightly decreased by 0.3-1.1 log units/g after the 15°C recovery phase. The results indicated heat stress induced inappetence corresponds to increased cast production accompanied by predominance of Vibrionaceae. Vibrionaceae colonizing the Atlantic salmon gut should be the focus of studies on the microbiology of thermally induced inappetence and dysbiosis in Atlantic salmon.
