| Abstract: | A male Thoroughbred fetus was
aborted on day 251 of pregnancy. Gross and histological examinations detected systemic
granulomatous lesions in many superficial and visceral lymph nodes and organs including
the liver, tonsils, lungs, thymus, spleen, right thyroid gland and gastrointestinal tract,
and suppurative placentitis, pyogranulomatous amnionitis and intralesional acid-fast
bacilli were also detected. An examination of the DNA base sequence of the β subunit of
RNA polymerase demonstrated that Mycobacterium avium strain 104 had
infected several organs. To the best of our knowledge, this is the first report of equine
fetal mycobacterial infection in Japan. |
