Observations of Bordetella bronchiseptica infections in dogs

摘要

The aim of the study was to present and develop a comprehensive diagnosis of B. bronchiseptica infections in dogs from Lublin Voivodeship and to determine whether these animals were infected with one or multiple genotypes of the bacteria. Thirty-five dogs with bordetellosis confirmed by bacteriological and molecular tests were included in the study. Samples of blood for hematology and biochemistry, as well as bronchial alveolar lavage for cytological and molecular tests, were taken from all animals. Seven dogs showed a decreased hematocrit and a decreased number of red blood cells. In 16 dogs, leukocytosis was found. Increased AST activity, increased ALT activity, elevated serum concentrations of urea, and increased creatinine concentrations were observed in 3, 5, 3, and 3 dogs, respectively. Endoscopy showed inflammation in the trachea and bronchi in 15 dogs. Cytological examination of bronchoalveolar lavages revealed a large number of macrophages (in 18 dogs), lymphocytes (in 8 dogs), and eosinophil granulocytes (in 2 dogs).
