This study confirms the role of birds of prey as a reservoir of enteropathogenic bacteria (i.e. Campylobacter spp., Escherichia coli, Salmonella spp.). Wild birds can contaminate environment with their faeces and play a crucial role in the transmission of pathogens to poultry and livestock farms and aquifers supplying water to humans. Furthermore, wild birds could disseminate pathogens within rescue and rehabilitation centres where they are admitted.

“…Antimicrobial‐resistant bacteria have been reported in the absence of antibiotic therapy, for example, in wild animals (e.g. Mare, 1968; Pagano et al., 1985; Gilliver et al., 1999; Costa et al., 2008; Guenther et al., 2010a,b; Molina‐Lopez et al., 2011) and insects (Rahuma et al., 2005). Bacteria resistant to antimicrobial substances are also found in environmental samples (e.g.…”

The occurrence of emerging infectious diseases and their relevance to human health has increased the interest in bats as potential reservoir hosts and vectors of zoonotic pathogens. But while previous and ongoing research activities predominantly focused on viral agents, the prevalence of pathogenic bacteria in bats and their impact on bat mortality have largely neglected. Enteric pathogens found in bats are often considered to originate from the bats' diet and foraging habitats, despite the fact that little is known about the actual ecological context or even transmission cycles involving bats, humans and other animals like pets and livestock. For some bacterial pathogens common in human and animal diseases (e.g. Pasteurella, Salmonella, Escherichia and Yersinia spp.), the pathogenic potential has been confirmed for bats. Other bacterial pathogens (e.g. Bartonella, Borrelia and Leptospira spp.) provide evidence for novel species that seem to be specific for bat hosts but might also be of disease importance in humans and other animals. The purpose of this review is to summarize the current knowledge of bacterial pathogens identified in bats and to consider factors that might influence the exposure and susceptibility of bats to bacterial infection but could also affect bacterial transmission rates between bats, humans and other animals.

“…Raptors that usually prey on sick or dead animals may be infected with Salmonella spp. at higher proportions than non‐predators birds (Millan et al., 2004; Molina‐Lopez et al., 2011; Reche et al., 2003). Likewise, birds feeding on the ground may have higher chances of getting infected than those feeding from hanging feeders (Refsum et al., 2003).…”

“…Salmonella is considered a ubiquitous agent that usually colonizes asymptomatically the guts of birds and can be further excreted through their faeces (Connolly et al., 2006). It is also relatively common to associate avian salmonellosis with die‐offs of backyard passerine birds (Alley et al., 2002; Refsum et al., 2003) or with sick birds arriving to wildlife rehabilitation centres (Molina‐Lopez et al., 2011; Reche et al., 2003). Reports on unapparent Salmonella carriers are less common, although from a zoonotic point of view, these birds would be the most problematic animals for people and livestock because of the potential risk they pose.…”

The epidemiology of subclinical salmonellosis in wild birds in a region of high Salmonella prevalence in pigs was studied. Three hundred and seventy-nine faecal samples from 921 birds trapped in 31 locations nearby pig premises, and 431 samples from 581 birds of 10 natural settings far from pig farms were analysed for the presence of Salmonella spp. Positive samples were serotyped and analysed for antimicrobial resistance (AR). Phage typing and pulsed-field gel electrophoresis (PFGE) on Salmonella Typhimurium isolates were also carried out. The overall proportion of Salmonella-positive samples was 1.85% (95% CI=0.93, 2.77). Salmonella isolation was positively associated with samples collected from birds in the proximity of a pig operation (OR=16.5; 95% CI=5.17, 52.65), and from non-migratory (or short-distance migration) birds (OR=7.6; 95% CI=1.20, 48.04) and negatively related to mostly granivorous birds (OR=0.4; 95% CI=0.15, 1.13). Salmonella Typhimurium was the most prevalent serotype and four different XbaI PFGE patterns were observed that matched the four phage types identified (U310, U311, DT164 and DT56). Only 20% of the strains showed multi-AR. In three farms, a high degree of homogeneity among isolates from different birds was observed. These findings suggested that pig farms may act as amplifiers of this infection among wild birds, and the degree of bird density may have much to do on this transmission. Some of the Salmonella serotypes isolated from bird faeces were of potential zoonotic transmission and associated with AR. Monitoring salmonellosis in wild bird is advised.
