Proposal for Designation of F38-Type Caprine Mycoplasmas as Mycoplasma capricolum subsp. capripneumoniae subsp. nov. and Consequent Obligatory Relegation of Strains Currently Classified as M. capricolum (Tully, Barile, Edward, Theodore, and Erno 1974) to an Additional New Subspecies, M. capricolum subsp. capricolum subsp. nov.

Abstract
A subspecies relationship with the existing species Mycoplasma capricolum is appropriate for the F38 group of mycoplasmas, the causative agent of classical contagious caprine pleuropneumonia. We believe that this classification is justified on the basis of the close DNA-DNA relationship recently reported for isolates belonging to the two groups and the other known serological and biological similarities and differences of these organisms. Strain F38T (T = type strain) and taxonomically indistinguishable strains are therefore proposed as members of a new subspecies of M. capricolum, M. capricolum subsp. capripneumoniae. Strain F38 (= NCTC 10192) is the type strain of M. capricolum subsp. capripneumoniae subsp. nov. As a consequence of this subdivision of the species M. capricolum, strains previously classified as M. capricolum are now necessarily relegated to subspecies status, as M. capricolum subsp. capricolum subsp. nov. Strain California kid (= ATCC 27343 = NCTC 10154) is the type strain of M. capricolum, as well as of M. capricolum subsp. capricolum. A taxonomic description of M. capricolum subsp. capripneumoniae and a brief amended description of M. capricolum subsp. capricolum are presented.
