The risk of salmonellae shedding by dogs fed Salmonella-contaminated commercial raw food diets.
ABSTRACT Twenty-eight research dogs were enrolled to determine the prevalence of salmonellae shedding after consumption of 1 Salmonella-contaminated commercial raw food diet meal. Sixteen dogs were exposed to Salmonella-contaminated commercial raw food diets and 12 to Salmonella-free commercial raw food diets. Seven of the exposed dogs shed salmonellae 1-7 days after consumption of Salmonella-contaminated raw food diets. None of the dogs fed Salmonella-free diets shed salmonellae. No clinical signs were observed in either group. Five of the 7 dogs shed the same serotypes as those recovered from food samples used for feeding. Results showed the same serotypes and antimicrobial resistance pattern in 2 of the 7 shedders. Dogs fed Salmonella-contaminated raw food diets can shed salmonellae and may, therefore, be a source of environmental contamination potentially leading to human or animal illness.

ABSTRACT: Abstract: Salmonella infection is one of the most important diseases that affect all animal species and is the leading cause of foodborne infections worldwide. One of the challenges in the control and prevention of salmonellosis is the recognition of potential carriers. To assess the potential role of shepherd dogs in the epidemiology of salmonellosis, fecal samples were taken from 38 shepherd dogs in Garmsar Province. Salmonella strains were isolated from 4 dogs (10.5%) related to 3 sheep flocks. All of the strains were confirmed at the genus level using invA virulence gene PCR. Serotyping confirmed all of the strains as Salmonella Reading. To study the clonal relatedness of the isolates, the strains were subjected to RAPD-PCR, and antimicrobial resistance patterns were also determined using 9 antibacterials. The similar RAPD-PCR profiles and resistance patterns strongly suggested that the shepherd dogs in the present study shed a similar clone of S. Reading; therefore, shepherd dogs can be recognized as a common source for this serotype in Garmsar.Turkish Journal of Veterinary and Animal Sciences 01/2013; 37:102-105.

ABSTRACT: Aims: Salmonellosis continues to be a major public health concerned globally. The objective of the study was to determine the occurrence and antimicrobial resistance pattern in Salmonella isolated from non-diarrheic stray and pet dogs in Klang Valley, Malaysia. Methodology and results: A total of 162 dogs were sampled, 15 (9.3%) were positive for Salmonella (stray dogs, n=12; pet dogs, n=3). All the isolates were identified as Salmonella using conventional culture methods and confirmed by PCR-targeting the invA gene. Four different Salmonella serovars were identified upon serotyping including Salmonella Corvallis (53.3%), S. Typhimurium (13.3%), S. Mbandaka (20%), and S. Agona (6.7%). Salmonella isolates were resistant to tetracycline (86.7%), sulphamethazole-trimethoprim (40%), ampicillin (40%), chloramphenicol (33.3%), streptomycin (33.3%), and enrofloxacin (26.7%). None of the isolates was resistant to gentamycin, cephalexin and amoxicillin-clavulanic acid. Eight isolates (53.3%) were multiple drugs resistant. Conclusion, significance and impact study: High number of canine Salmonella isolates developed resistance and this may likely be public health concern.
