| Summary: | In this study, a case of exudative type tuberculosis due to
M. bovis infection was identified in a 2 month-old Holstein
female calf that was treated with antibiotic treatment due
to cough and respiratory problems in the neonatal period.
Systemic necropsy revealed caseific nodules scattered across
the entire lung, except the dorsal parts of the caudal lobes
of the lung, and prominent interlobular edema was observed
in the dorsal caudal regions. Histopathologically, exudative
lesions that extensive caseification necrosis and calcification
with diffuse inflammatory cells and Langhans type giant cells
without fibrous capsule were seen in the lung parenchyma.
Smaller and lesser number of similar granulomas was found
in the liver and brain. Acid resistant bacteria in Ziehl-Neelsen
staining were determined to be Mycobacterium bovis in immunohistochemical
staining. It is aimed to draw attention to
the fact that bovine tuberculosis should be considered as one
of the important diseases affecting the calves in the neonatal
period and may cause serious economic losses if no measures
are taken. |
