Antimicrobial resistance of staphylococci and streptococci isolated from dogs.

A study was conducted for the examination of bacterial species isolated in dogs from Animal Clinics of Nanjing Agricultural University, China. Forty nasal swabs were taken from dogs having respiratory signs. Staphylococcus pseudintermedius was the most frequently isolated pathogen (37.50 %) followed by Staphylococcus aureus (18.75%), Streptococcus pluranimalium (10.93%), Streptococcus canis (9.37%), Staphylococcus schleiferi (9.37%), Staphylococcus intermedius (6.25%), Staphylococcus cohnii (4.71%) and Staphylococcus hominis (3.12%). S. pseudintermedius and S. pluranimalium were subjected to commonly used antibiotics for determination of resistant drugs. Antimicrobial resistance in S. pseudintermedius was common in gentamicin (70.83%) and tetracycline (50%) while in S. pluranimalium was common in enrofloxacin (71.42%) and gentamicin (57.14%).
