Abstract

The purpose of this investigation was to give a survey of the classification of ovine/caprine mycoplasmas as a basis for the identification of strains isolated from sheep and goats. A total of 13 strains representing 13 species and/or serogroups were biochemically examined, and serological cross-titrations were performed using metabolism inhibition, growth inhibition and immunofluorescence. Serogroup 6 (Al-Aubaidi) was found to be identical with Mycoplasma capricolum.

The results of identification of 57 isolates, sent to the reference centre from different countries, are given.

On the basis of the above investigations and a comparison of some of the classification systems described in the literature, it is concluded that the following species have been isolated from goats and/or sheep: M. agalactiae, M. arginini, M. bovis, M. capricolum, M. conjunctivae, M. mycoides subsp. capri, M. mycoides subsp. mycoides, M. ovipneumoniae, M. putrefaciens, Acholeplasma granularum, A. laidlawii and A. oculi. In addition, both Ureaplasmas and strains representing 6 serogroups (groups 5, 7, 10 and 11 of Al-Aubaidi and groups 17 and 18 of Cottew) have been isolated. These serogroups ought to be finally species-classified as soon as possible. kw|Keywords|k]ovine/caprine mycoplasmas; k]classification; k]identification
