Abstract
Background and Aim: The bacterium Escherichia coli, which is naturally isolated from the human and animal digestive tract, is considered one of the most important microbiotas (natural flora) members of the device, and its pathogenic form causes very important complications in humans and animals. Pathogenic strains are divided into two groups: intestinal and extracorporeal pathogens. The aim of this study is to determine the resistance and sensitivity of Escherichia coli bacteria isolated from healthy camels.
Materials and Methods: The study collected 26 swabs of healthy camels from the city of Mashhad. Anal swabs were cultivated on the McConkey agar culture medium, and the separations obtained were confirmed by biochemical tests. The resistance and sensitivity of the separations were examined by the disk diffusion method.
Results: The results of the study showed that the highest resistance of the studied separations related to the antibiotic penicillin was 46.88%, followed by the antibiotics streptomycin (38.15%), amoxicillin (53.11%) and gentamycin (69.7%).
Conclusion: The results of this study show that the agar diffusion disc method can be used as a primary screening method to determine the sensitivity and antibiotic resistance of Escherichia coli bacteria compared to various antibiotics.
