title: Klebsiella oxytoca as a cause of equine abortion--short communication.
abstract: Klebsiella (K.) oxytoca infection induced the abortion of a female equine fetus in the 10th month of pregnancy. Bacteria were cultured from the liver, lung and stomach content. They were labelled with an anti-Mycobacterium bovis antibody in the thymus, liver and lungs and were stained with Giemsa and Brown-Brenn staining in the thymus and lung. The diffusely consolidated lungs contained numerous grey-whitish foci 2-4 mm in diameter, which corresponded to severe pyogranulomatous pneumonia characterised by numerous intraalveolar neutrophils and macrophages and multinucleated Langhans' giant cells. K. oxytoca was located in the cytoplasm of these cells, and extracellularly in the lumen of alveoli, bronchioles and bronchi, in the capsule of thymus and in the sinusoids of the liver. The results indicate that K. oxytoca can cause sporadic equine abortion.
