Abstract

Escherichia coli, which is naturally isolated from the gastrointestinal tract of humans and animals, is one of the most important members of the microbiota (natural flora) of this system and its pathogenic form can cause very serious complications in humans and animals. The germs are divided into two groups of intestinal and extra-intestinal pathogens. The aim of this study was to determine the resistance and susceptibility of Escherichia coli isolated from healthy camels.
In this study, 26 intestinal swabs were collected from healthy camels in Mashhad. Anal swabs were cultured on MacConkey agar medium and the isolates were confirmed by biochemical tests. The resistance and susceptibility of the isolates were determined by disk diffusion method.
The results of this study showed that the most resistant isolates were penicillin antibiotic (88.46%) and streptomycin (15.38%), amoxicillin (11.53%) and gentamicin. (7.69%) followed.
The results of this study indicate that disk diffusion agar method can be used as a primary screening method to determine the sensitivity and antibiotic resistance of Escherichia coli to various antibiotics
