Prevalence and Antimicrobial Resistance of Bacteria Isolated From Stray Dogs and Cats of District Hyderabad

The present study was conducted to know the prevalence and antimicrobial resistance of bacteria isolated from stray dogs and cats in Hyderabad and Tandojam regions. A total of 100 samples (saliva, tail wound, otitis, skin wound, nasal discharge, fecal samples were collected. The samples were identified by morphological, cultural and biochemical tests. The antibiogram of the isolated species were conducted using disk diffusion method. The results demonstrated that prevalence of bacterial pathogens in saliva was 0.06% in stray cats and dogs of Tandojam and Hyderabad respectively. From tail wound prevalence of 02 (0.2%) in cats of Tandojam and Hyderabad, while in dogs 03 (0.3%) in Hyderabad and 02 (0.2%) in Tandojam was observed. From otitis 1 (0.09%) in cats of Tandojam and Hyderabad, while in dogs 02 (0.18%) in Hyderabad and 01 (0.09%) in Tandojam was observed. From skin wound 03 (0.39%) in cats of Hyderabad region and 02 (0.26%) from Tandojam region, while in dogs 02 (0.26%) in dog of Hyderabad region and 03 (0.39%) from Tandojam region was observed. From nasal discharge 01 (0.05%) cat and dog of Hyderabad and Tandojam regions were observed. From fecal sample 01 (0.07%) in cat and dogs of Hyderabad and Tandojam regions was observed. Antibiotic resistance tests revealed that erythromycin and ofloxacin exhibited high resistance against Staphylococcus aureus. Ampicillin and gentamycin were identified as highly resistance against Bacillus cereus. Pasteurella canis displayed high resistance to ampicillin, enrofloxacin, and ofloxacin. Escherichia coli exhibited high resistance to enrofloxacin and ofloxacin. Micrococcus luteus showed high resistance to ampicillin and enrofloxacin. Pseudomonas aeruginosa and Streptococcus pyogens demonstrated high resistance to enrofloxacin. Based on the findings of the current study, it was concluded that the higher prevalence was observed in saliva, tail, otitis, skin, nasal discharge, and fecal samples. The isolates were Staphylococcus aureus, followed by Micrococcus luteus, Escherichia coli, Bacillus cereus, Pasteurella canis, Pseudomonas aeruginosa, and Streptococcus pyogens, respectively.
