In this study we aimed to investigate salmonella and E. coli serovars from fecal swabs collected
from apparently healthy and diarrheic dogs and cats by bacteriological examination. 150 fecal
samples of dogs and cats were examined for salmonella and E. coli species. Salmonella species
were isolated from 40 cases out of 150, 30 of the salmonella positive samples were from dogs
(31.6%), and 10 were from cats (18.2%) while 45 samples were positive for E. coli, 25 from
dogs (26.4 %) and 20 from cats (36.4 %). E. coli and salmonella positive samples were
subjected to antimicrobial disc diffusion susceptibility test by using 10 different antibiotic
discs. Molecular investigation was done to detect the virulent gene of salmonella (inv A) and
E. coli (eae A) and antibiotic resistant gene for both salmonella and E. coli (blaTEM) using PCR.
