Bacterial respiratory tract infection in dog

Abstract

The research entitled “Bacterial Respiratory Tract Infection in Dog” was undertaken w.e.f. October 2022 to June 2023 in the Veterinary Clinical Complex, College of Veterinary Science, Assam Agricultural University, Khanapara, and Guwahati with the objective of isolation and identification of bacterial isolates along with therapeutic regimen based on in-vitro antibiotic sensitivity test. Nasal swab samples were collected by using sterile swabs aseptically from the suspected animals for isolation, identification of the bacteria and performed in-vitro antibiotic sensitivity test and rendered treatment in the three treatment groups (Group B, Group C and Group D). The most common clinical findings observed were moist cough, inappetence and wheezing sound of the lung elicited through thoracic auscultation. Staphylococcus spp. concurrently with Escherichia coli (30.00%) were common isolates. In in-vitro antibiotic sensitivity test Staphylococcus spp., Klebsiella pneumoniae, Pseudomonas spp. and Bacillus spp. showed highest sensitive to Ceftriaxone. Escherichia coli and Bacillus spp. showed highest sensitive to Doxycycline. Ceftriaxone sodium was found (100.00%) effective followed by Doxycycline hydrochloride and Enrofloxacin (90.00%).
