Dogs that participate in animal-assisted interventions (AAIs), often called 'therapy dogs', commonly interact with humans whose immune systems are not functioning optimally. [] Key Method Two hundred healthy therapy dogs from Ontario and Alberta were enrolled. Between May 2005 and November 2006, fecal specimens were collected from each dog every 2 months for 1 year, along with a log of places visited, antimicrobial use within the home, dog health status and diet.

The Occurrence and Antimicrobial Susceptibility of Salmonellae Isolated from Commercially Available Canine Raw Food Diets in Three Canadian Cities

The potential risk of raw food diets, especially for immunocompromised individuals, is demonstrated, and the need for implementing regulatory guidelines for the production of these diets is stressed in order to help control and ideally eliminate the bacterial risks associated with their use and consumption.

Salmonella in companion animals

The investigations carried out suggest that asymptomatic carriage of Salmonella in UK dogs is low however the microorganism remains as a zoonotic and anthroponotic pathogen based on phenotypic and genotypic characterisation however there may be potential for particular serotype to become host restricted as observed in invasion assays.

Fecal Shedding of Multidrug Resistant Escherichia coli Isolates in Dogs Fed with Raw Meat-Based Diets in Brazil

It is suggested that feeding an RMBD can affect the dog’s microbiota, change the frequency of certain phylogroups, and increase the shedding of diarrheagenic E. coli.

Fecal shedding of Salmonella spp., Clostridium perfringens, and Clostridioides difficile in dogs fed raw meat-based diets in Brazil and their owners’ motivation

The present work revealed that the owners have a tendency to ignore or are unaware of the risks associated with raw meat diets for dogs, and the higher fecal shedding of important enteropathogens in dogs fed RMBD suggests that this diet poses a risk for the animals and the people in contact with them.

Isolation of Salmonella species of public health concern from commonly fed dried meat dog treats.

Dog owners, pet food retailers and veterinary professionals should be aware of the potential zoonotic disease risk associated with these treats, and appropriate hygiene measures, including thorough hand washing, should be utilised if they are fed.

Risk factors for carriage of antimicrobial-resistant Salmonella spp and Escherichia coli in pet dogs from volunteer households in Ontario, Canada, in 2005 and 2006.

Several potentially important pet-related risk factors for the carriage of antimicrobial-resistant Salmonella spp and E coli in pet dogs were identified and may lead to development of evidence-based guidelines for safe and responsible dog ownership and management.

Septicaemia and thrombocytopenia caused by Salmonella gallinarum in a dog fed a raw meat-based diet

The case of a 5-month-old female French Bulldog referred for investigation of acute vomiting, diarrhoea and pyrexia is reported, the first report of septicaemia with positive blood culture for Salmonella gallinarum, with secondary severe thrombocytopenia in a dog that was fed a raw meat diet.

Presence of pathogenic bacteria in faeces from dogs fed raw meat-based diets or dry kibble

There was a significant difference in excretion of zoonotic and resistant bacteria in faeces between dogs fed RMBD and dogs fed dry kibble, confirming that R MBD can pose a microbiological risk not only for dogs, but also for people handling RMBd and faece from dogs.

Salmonella serotypes and their antimicrobial susceptibility in apparently healthy dogs in Addis Ababa, Ethiopia

This study demonstrated high carriage rate of Salmonella serotypes known for causing human salmonellosis and large proportion of them were resistant to antimicrobials used in public and veterinary medicine for management of various bacterial infections, suggesting the possible risk of infection of human population in close contact with these dogs by drug resistant pathogens.

Incidence of acquisition of methicillin-resistant Staphylococcus aureus, Clostridium difficile, and other health-care-associated pathogens by dogs that participate in animal-assisted interventions.

Among dogs that visited human health-care facilities, those that licked patients or accepted treats during visits were more likely to be positive for MRSA and C difficile than were dogs that did not lick patients or accept treats.

The Occurrence and Anti‐microbial Susceptibility of Salmonellae Isolated from Commercially Available Pig Ear Pet Treats

The prevalence observed during this study is lower than the prevalence observed in 1999, but pig ear treats should still be considered as a possible source of Salmonella and anti‐microbial resistant bacteria to humans and dogs in Canada.

Prevalence of zoonotic agents in dogs visiting hospitalized people in Ontario: implications for infection control.

Evaluation of the association between feeding raw meat and Salmonella enterica infections at a Greyhound breeding facility.

Investigating Salmonella enterica infections at a Greyhound breeding facility suggested that several strains of S. enterica existed at the facility, but there was a high degree of relatedness among many of the Newport isolates.

Evaluation of bacterial and protozoal contamination of commercially available raw meat diets for dogs.

Bacterial contamination is common in commercially available raw meat diets, suggesting that there is a risk of foodborne illness in dogs fed these diets as well possible risk for humans associated with the dogs or their environments.

The risk of salmonellae shedding by dogs fed Salmonella-contaminated commercial raw food diets.

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.

Characterization of SalmonellaAssociated with Pig Ear Dog Treats in Canada

P pig ear pet treats are established as the cause of an outbreak of human disease caused by Salmonella enterica serotype Infantis and several otherSalmonella serotypes were also isolated from pet treats, suggesting these products may be an important source of enteric infection in both humans and dogs.

Human health implications of Salmonella-contaminated natural pet treats and raw pet food.

Pet owners can reduce their risk of acquiring Salmonella organisms by not feeding natural pet treats and raw food diets to their pets, whereas individuals who investigate cases of salmonellosis or interpret surveillance data should be aware of these possible sources of Salmonelli organisms.

Bacteriological evaluation of commercial canine and feline raw diets.

Twenty-five commercial raw diets for dogs and cats were evaluated bacteriologically; however, E. coli O157 was not detected and a toxigenic strain of C. difficile was isolated from one turkey-based food.

Vancomycin resistance and antibiotic susceptibility of enterococci in raw meat.

Resistance to vancomycin was significantly associated to methicillin, teicoplanin, erythromycin, tetracycline, and chloramphenicol, and further investigations about enterococcal colonization and infections in community and hospital subjects are needed.
