“…Fuerteventura showed intermediate values and Cádiz showed the lowest affinity, probably because of the high consumption of wild prey instead of livestock carrion by those vultures. The antibiotic resistance rate among bacterial isolates found in this study was very high compared with the available data from wild birds (Tsubokura et al, 1995;DeBoer et al, 2001;Livermore et al, 2001;Nascimento et al, 2003;Dobbin et al, 2005), especially in Segovia where the proportion of stabled livestock in the diet was highest. High consumption by vultures of stabled livestock carrion was associated with increasing antimicrobial resistance in animal pathogens (e.g.…”

The impact on wildlife health of the increase in the use of antimicrobial agents with the intensification of livestock production remains unknown. The composition, richness and prevalence of cloacal microflora as well as bacterial resistance to antibiotics in nestlings and full-grown Egyptian vultures Neophron percnopterus were assessed in four areas of Spain in which the degree of farming intensification differs. Differences in diet composition, especially the role of stabled livestock carrion, appear to govern the similarities of bacterial flora composition among continental populations, while the insular vulture population (Fuerteventura, Canary Islands) showed differences attributed to isolation. Evidence of a positive relationship between the consumption of stabled livestock carrion and bacterial resistance to multiple antibiotics was found. Bacterial resistance was high for semisynthetic penicillins and enrofloxacin, especially in the area with the most intensive stabled livestock production. The pattern of antibiotic resistance was similar for the different bacterial species within each area. Bacterial resistance to antibiotics may be determined by resistance of bacteria present in the livestock meat remains that constituted the food of this species, as indicated by the fact that resistance to each antibiotic was correlated in Escherichia coli isolated from swine carrion and Egyptian vulture nestlings. In addition, resistance in normal faecal bacteria (present in the microflora of both livestock and vultures) was higher than in Staphylococcus epidermidis, a species indicator of the transient flora acquired presumably through the consumption of wild rabbits. Potential negative effects of the use of antimicrobials in livestock farming included the direct ingestion of these drug residues and the effects of bacterial antibiotic resistance on the health of scavengers.

Wild birds have been postulated as sentinels, reservoirs, and potential spreaders of antibiotic resistance. Antibiotic-resistant bacteria have been isolated from a multitude of wild bird species. Several studies strongly indicate transmission of resistant bacteria from human rest products to wild birds. There is evidence suggesting that wild birds can spread resistant bacteria through migration and that resistant bacteria can be transmitted from birds to humans and vice versa. Through further studies of the spatial and temporal distribution of resistant bacteria in wild birds, we can better assess their role and thereby help to mitigate the increasing global problem of antibiotic resistance.

“…In the past, Enterobacteriaceae have been isolated regularly from healthy omnivorous, piscivorous and carnivorous birds (Bangert et al 1988;Gl€ under 2002;Ajuri et al 2004;Dobbin et al 2005;Gibbs et al 2007), since animal protein as part of the diet seems to be a factor that favours the colonization of the digestive tract with Enterobacteriaceae (Gl€ under 2002). Other authors state that they usually do not belong to the normal gastrointestinal flora of granivorous and herbivorous birds (Brittingham et al1988;Gerlach 1994).…”

“…Although E. coli is often implicated in avian disease processes (Gerlach 1994;Fudge 2001), it is a well-documented member of the normal pharyngeal or gastrointestinal flora of many nonpasserine avian species, including anatids (Aguirre et al 1992;Ewers et al 2009), cormorants (Dobbin et al 2005), various seabirds (Steele et al 2005), grey herons (Gl€ under 1989) and carnivorous birds (Bangert et al 1988), in which it usually represents one of the most prevalent bacterial species. In contrast, presence of E. coli in passerine birds is considered abnormal, and the prevalence uses to be low (Brittingham et al 1988;Gerlach 1994).…”

“…Knowledge of the normal gastrointestinal flora is limited for the majority of free-living bird species. Most studies are concentrating on few bacteria that are known to be zoonotic or related to outbreaks of avian disease, or on avian species with commercial interest as falconry, pet or game birds (Bangert et al 1988;Brittingham et al 1988;Gl€ under 1989;Lamberski et al 2003;Dobbin et al 2005;Gibbs et al 2007). Various species of wild birds have been also incriminated as reservoirs for bacterial pathogens able to cause disease in humans, or to contribute to microbial contamination and eutrophication of surface waters (Wi sniewska et al 2007;Ewers et al 2009).…”
