Abstract
The present study was undertaken on dogs presented to the Veterinary Clinical Complex of F.V.Sc and A.H., R.S. Pura, to find out the occurrence, diagnosis and therapeutic management of bacterial respiratory tract infections in dogs. A total of 2754 dogs were presented out of which 51 dogs (1.85%) were affected with respiratory tract diseases. Out of these 43.14% were of bacterial origin. The highest occurrence of bacterial respiratory infections was seen in the <2-year age group (54.54%) and in the winter months (40.90%). Sex-wise males were reported in higher numbers (72.72%). Breed-wise Labrador retrievers were seen in the highest numbers (36.36%). The major clinical signs seen were cough, nasal discharge, exercise intolerance, presence of abnormal respiratory sounds, inappetence, lethargy and weight loss. Physical examination revealed tachypnoea, dyspnoea, fever, crackles, wheezes and harsh lung sounds. Hematological study revealed leucocytosis with neutrophilia along with increased plasma fibrinogen. Thoracic radiography revealed alveolar, interstitial, and bronchial patterns. Staphylococcus spp. and E. coli followed by Streptococcus spp, Klebsiella spp., were the most commonly isolated bacteria. The comparative cellular findings of tracheal aspirates revealed a significant increase in neutrophils. Blood gas analysis revealed significantly increased pCO2 levels. Bacteria were found to be most susceptible to gentamicin, chloramphenicol, doxycycline and levofloxacin and least sensitive to ampicillin on antibiotic sensitivity testing. Significant improvement in the clinical signs, haemato-biochemical parameters and physiological parameters was seen on 14 days post-treatment.
