In our retrospective study we executed a comparative microbiological evaluation of airway fluid samples of dogs with respiratory tract infection. The 367 dogs investigated were referred to SZIE ÁOTK, Department and Clinic of Internal Medicine between 2008 and 2013.

Nasal swabs, and airway fluid samples gained via trachea lavage and bronchoalveolar lavage (BAL) was sent to microbiological examination in transport medium.

Sampling from the lower airways was performed under general anaesthesia with flexible endoscope.

Our results show that the most common isolate was Staphylococcus pseudointermedius (28,69%) followed by ß-haemolysed Streptococcus (16,39), and Staphylococcus aureus from the nasal cavity (15,57%). From the trachea lavage the results were Coliforms (33,33%), Bordetella bronchiseptica (23,08%) and Pseudomonas aeruginosa (12,82%) in order of frequency.

In BAL samples Pseudomonas aeruginosa was found in the biggest number (28,16%) , which was followed by Coliform bacteria ( 24,27%), and Bordetella bronchiseptica (22,33%).

Beside the bacterium species cultured from the samples we discuss the antibiotics resistance relations and the diagnostic difficulties focused on the ‘de facto’ role of bacteria cultures from not inherently sterile airways in a direct touch with the external environment.

This study is pioneer in the Hungarian veterinary practice. Beside the veterinary therapy it is significant even at a human public health context.
