Abstract
Cultures for Ureaplasma isolation were made from the oral cavity, nasal cavity, eye, rectum, prepuce and vagina of 62 goats of 3 separate herds and 11 sheep of 1 herd. All animals were apparently healthy. Ureaplasmas were obtained from the prepuce (6/16, 37.5%) and vagina (18/46, 39.1%) of goats and from the prepuce (1/5, 20%) and vagina (2/6, 33.3%) of sheep, but not from any other organ. The caprine and ovine Ureaplasma strains were examined serologically by the growth inhibition and metabolism inhibition tests. Of the caprine strains, 23 formed a single serological group and 21 ovine strains were divided serologically into 20 forming a group and 1 distinct from these strains. Two groups of Ureaplasma strains isolated from the goats and sheep and 1 ovine strain had a common antigen. Neither caprine nor ovine strains had any serological relationship with human, bovine, canine, simian or avian strains. Since caprine and ovine strains have an antigenic similarity, the host-specificity of Ureaplasma may be an exception for the caprine and ovine strains.
