Plain-English summary
A male Thoroughbred fetus was aborted at 251 days into the pregnancy. Doctors found serious infections in many parts of the body, including the lymph nodes, liver, lungs, and gastrointestinal tract, along with inflammation in the placenta and amniotic fluid. Tests showed that the fetus was infected with a type of bacteria called Mycobacterium avium. This case is notable because it is the first time such an infection in a horse fetus has been reported in Japan.
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.
