Frequency of Salmonella spp. in feces of domestic dogs in the city of Puebla, Mexico

Abstract

The disease caused by Salmonella spp. is called salmonellosis and can make humans and animals sick; These bacteria can be expelled through fecal matter and are acquired by contact with it or by ingestion of contaminated food. It is estimated that approximately 9% of cases in people are attributable to contact with animals, due to the frequency of Cases of infection by this bacteria can be called a public health problem and represent a greater risk for immunocompromised people, the elderly and children. With the objective of determining the frequency of Salmonella spp. in feces of domestic dogs in the city of Puebla, Mexico; 100 samples of canine feces were collected regardless of the sex, breed and age of the dog. Subsequently, the search for Salmonella was carried out by conventional microbiological methods, the strains identified as Salmonella were identified by agglutination of antisera and antimicrobial sensitivity tests were performed. The results determined a Salmonella frequency of 2% (2/100). The two Salmonella strains belong to serogroup B, one of them showed high sensitivity to all antibiotics tested including 3rd and 4th generation cephalosporins and carbapenems while the second Salmonella strain showed resistance to cefepime.
