Investigate and determine the sensitivity and antibiotic resistance of bacteria isolated from feces of diarrheal healthy dogs and cats

Objectives: Antibiotic resistance due to the worldwide usage of antibiotics is one of the biggest failures in antibiotic treatment. The aim of this study is determine bacteria and also investigate the sensitivity and antibiotic resistance of bacteria isolated from feces of diarrheal healthy dogs and cats in Tabriz city in 2015.Materials Methods: In this study 50 cases of bacteria isolated from feces of diarrheal and 50 cases of healthy dogs and cats were determined. As well as the effect of oxytetracycline, azithromycin, cefixime, tetracycline, tylosin, gentamaicin, sulphadiazine, chloramphenicol antibiotics were evaluated on bacteria isolated by disc diffusion method. Campylobacter were confirmedby multiplex PCR and salmonella by PCR and using invA gene specified primers.Results Conclusion: Results related to studied antibiotics effects showed that all isolated bacteria were sensitive with high percentageto sulphadiazine, cefixime andtylosin. On resistance of isolated bacteria to antibiotics, they were resistant topenicillin (94 percent), chloramphenicol (62 percent), gentamaicin (45 percent), tetracycline (34 percent), oxytetracycline (25 percent) and azithromycin (15 percent). E. coli bacteria had full resistance to penicillin and azithromycin. Results were also indicated that the percentage of E. coli, pseudomonas aeruginosa, proteus, lactobacillus, clostridium perfringens in healthy dogs and cats were more than diarrheal ones. In other hand, the percentage of staphylococcus aureus, corynebacterium, salmonella and bacillus cereus in diarrheal dogs and cats were more than healthy. Also, cats given campylobacter were more than dogs.
