Surveys on some bacterial respiratory diseases of dogs in Can Tho city

Abstract

This study was conducted to diagnose the bacterial respiratory diseases of dogs in Can Tho city by using clinical examination, X-ray and bacterial isolation and to determine the antibiotic susceptibility of the isolated bacteria strains by antibiotic susceptibility test.The studied results showed that there were 211 out of 2010 examined dogs suffered with respiratory diseases, accounted for 10.49%. The rate of acute respiratory diseases (72.04%) was higher than that of chronic ones (27.96%). The acute respiratory disease in dogs showed clinical signs clearer than chronic ones. The common symptoms were observed in the diseased dogs including increase of respiratory rhythm (76.30%), cough (49.76%), nasal fluid discharge (47.39%) and fever (41.23%). The respiratory disease often occurred in the puppies from 2-6 months old (12.78%) and in the dogs over 2 years old (11.11%). The rate of respiratory diseases in the exotic dogs (12.75%) was higher than that in the local ones (7.99%). The higher rate of respiratory disease was found in the free-ranging dogs (13.12%) and in seasonal change (25.66%).The common bacteria isolated from the respiratory disease dogs in Can Tho city were Staphylococcus, E. coli, Streptococcus, Pseudomonas and Pasteurella, of which Staphylococcus accounted for the highest rate (39.07%). The common bacteria species were Staphylococcus aureus, Staphylococcus intermedius, Staphylococcus epidermidis, Streptococcus zooepidemicus, Streptococcus agalactiae, Streptococcus pyogenes, Pseudomonas aeruginosa, Pasteurella multocida and Pasteurella haemolytica. Norfoxacin and gentamycin were found as the effective antibiotics for respiratory disease treatment caused by bacteria in dogs.
