“…The results obtained during the present study support the conclusion of Jones & Twigg ( 1976) that infections with Salmonella in populations of small wild mammals are very rare and that such mammals are unlikely to constitute an important reservoir of infection for domestic animals. The bacteria other than Salmonella identified by the API 20-E system are almost all common inhabitants of the mammalian gut.…”

“…Despite various attempts, no Salmonella isolate was detected in any of the fecal samples tested. These results support the finding of other researchers that Salmonella occurs very infrequently in wild small animals (13,15,28). The low rate of occurrence of E. coli and the absence of Salmonella in the gastrointestinal tracts of wild small mammals may be attributable to the diet of these animals, which can vary depending on the geographic location, the population density, and seasonal variations in the food supply (21,38).…”

Wild animals not normally exposed to antimicrobial agents can acquire antimicrobial agent-resistant bacteria through contact with humans and domestic animals and through the environment. In this study we assessed the frequency of antimicrobial resistance in generic Escherichia coli isolates from wild small mammals (mice, voles, and shrews) and the effect of their habitat (farm or natural area) on antimicrobial resistance. Additionally, we compared the types and frequency of antimicrobial resistance in E. coli isolates from swine on the same farms from which wild small mammals were collected. Animals residing in the vicinity of farms were five times more likely to carry E. coli isolates with tetracycline resistance determinants than animals living in natural areas; resistance to tetracycline was also the most frequently observed resistance in isolates recovered from swine (83%). Our results suggest that E. coli isolates from wild small mammals living on farms have higher rates of resistance and are more frequently multiresistant than E. coli isolates from environments, such as natural areas, that are less impacted by human and agricultural activities. No Salmonella isolates were recovered from any of the wild small mammal feces. This study suggests that close proximity to food animal agriculture increases the likelihood that E. coli isolates from wild animals are resistant to some antimicrobials, possibly due to exposure to resistant E. coli isolates from livestock, to the resistance genes of these isolates, or to antimicrobials through contact with animal feed.

“…Whilst it is not possible to identify any vector with certainty, the possibilities would include farm visitors 304 Salmonella infection in calves 305 and farm personnel whose work may take them onto different farms in the same area. Another possibility is wild-life, and although salmonellas have been isolated from many species of animals [12] such infection generally appears to indicate a contaminated environment [13].…”

SUMMARYSalmonellas were detected in the environment of 10 of the 12 calf dealers' premises studied. The cleaning and disinfection routines were often ineffective and salmonellas were isolated from 7-6 % and 5-3 % of the wall and floor samples before disinfection and 6-8 % and 7-6 % afterwards. Eight different salmonella serotypes were detected, of which the commonest were Salmonella typhimurium, predominantly phage type DT204C, and S. dublin. Plasmid profiles were used to fingerprint S. typhimurium DT204C and the results indicated that with the exception of one of the premises, prolonged salmonella-persistence in the environment was not occurring.Three separate epidemics of salmonellosis in calves were studied by use of plasmid profile analysis. The results illustrated the role of dealers, and their subcontractors, in the dissemination of salmonellas. The study concludes with suggestions for methods to reduce the spread of salmonellas in the calf marketing chain.
