Features of clinical manifestations and pathomorphological characteristics of Bordetellosis in dogs

The results of the studies showed that the clinical signs of Bordetella infection in dogs are pronounced and have characteristic manifestations. These signs typically last for three to four months and then disappear. The most pronounced symptom was coughing, ranging from a rare, mild, productive cough to a severe, dry cough accompanied by suffocation attacks and vomiting. We recorded the most pronounced damage and typical pathomorphological changes in the respiratory organs of all dead dogs. The mucous membranes of the trachea and bronchi were hyperemic, and their lumens contained foamy sputum. Signs of catarrhal or catarrhal-purulent inflammation, emphysema, and hyperemia were detected in the lungs. A heterogeneous, spotted, marbled pattern was observed on the surface of the lungs, especially in the dorsal regions, which is characteristic of this infection. According to our studies, the infection was found in animals of all age groups. However, it was more frequently recorded and proceeded particularly severely in puppies aged two to five weeks and six months. In most cases, bordetellosis resulted in recovery following adequate etiological and symptomatic therapy; however, complications and animal deaths were frequently reported. According to our observations, mortality was low in complicated cases, ranging from 7% to over 22%
