Investigation on the bacterial of dog's hemorrhagic enteritis and determining their antibiotic resistance in Rasht veterinary clinics

The goal of this experiment was to separate the elements producing hemorrhagic enteritis in dogs and determining resistance or sensitivity to antibiotic compared with the common antibiotics (gentamicine, tetracycline, nalydixic acid, cefexim, cefriaxon, penicillin, chloramphenicol, cotrimoxazole). In this research, feces samples had been taken from 80 dogs in ages between 6 months to 2 years that suffer from hemorrhagic enteritis and did not receive antibiotics. In order to recognizing producing bacterial elements, samples moved to various culture medias and after bacteriologic investigation, four bacteria including Escherichia coli, clostridium, campylobacter and salmonella were spread from the samples which were taken from 80 dogs. The results show that 21.25% of dogs are contaminated to salmonella, 8.75% to clostridium, 26.25% to campylobacter, and 43.75% to E coli The hemorrhagic enteritis are indicated from the other bacteria, as well as the resistance of these bacteria to the most studied antibiotic groups, but this antibiotic indicates well sensitivity than cefriaxone and cefixim antibiotics. The other bacteria also indicates well sensitivity to these two drugs.
