Mycobacterium bovis infection in a wild sow ( Sus scrofa ): the first case in Korea

View Article: PubMed Central - PubMed

ABSTRACT

Mycobacterium (M.) bovis causes tuberculosis and has a broad host range, including humans, livestock, and wild animals. M. bovis infection of wild boar has been reported in several European countries. We report here the first case of M. bovis infection in a domesticated wild sow in Korea. Granulomatous and necrotizing lesions with small numbers of acid-fast bacilli were observed in nodules of the lung of wild sow. Furthermore, the M. bovis isolate from the wild sow had spoligotype SB0140 and a novel MIRU-VNTR allelic profile, which is not found in cattle and deer in Korea.

Visible lesions and Ziehl-Neelsen staining of the lungs of wild sow. (A) Visible lesions in the nodules of the lung from a wild sow showing well-demarcated yellow caseous nodules (arrowheads) at the cut surface. (B) Ziehl–Neelsen staining of a lung section nodule shows acid-fast bacilli (arrows) in a granuloma. Scale bar = 10 µm.

Figure 1: Visible lesions and Ziehl-Neelsen staining of the lungs of wild sow. (A) Visible lesions in the nodules of the lung from a wild sow showing well-demarcated yellow caseous nodules (arrowheads) at the cut surface. (B) Ziehl–Neelsen staining of a lung section nodule shows acid-fast bacilli (arrows) in a granuloma. Scale bar = 10 µm.

Mentions: The nodules in the lung were very firm (panel A in Fig. 1), and their cut surface revealed thick yellow caseous material. The histopathology of lymph node sections revealed granulomatous and necrotizing lesions with small numbers of acid-fast bacilli (panel B in Fig. 1).
