Dogs identified as spreaders of antimicrobial-resistant Salmonella
Antibiotic-resistant Salmonella is a serious public health concern that has increased recently as the bacteria has developed ways to survive drugs. According to the U.S. Centers for Disease Control and Prevention, people can get Salmonella from eating contaminated food products or from infected people or animals — typically via unintentional contact. A team of Penn State researchers has now discovered that household dogs are an overlooked transmission point for zoonotic pathogens that cause Salmonella. This can cause diarrhoea, fever, and abdominal cramps, and some infections can potentially have life-threatening complications. The researchers reported that, given dogs’ proximity to humans and the use of critically important antibiotics in companion animal medicine, household dogs represent a risk for the spread of antimicrobial-resistant Salmonella. They found that better awareness of the risk and proper hygiene could potentially help mitigate cross-species infections. How dogs spread antimicrobial-resistant Salmonella Salmonella infections in dogs can be clinical — showing signs or symptoms — or asymptomatic, with numerous studies reporting Salmonella isolation from clinically healthy dogs, according to team leader Erika Ganda.
