Abstract
This paper concerns the taxonomic status of the F38-like group (MacOwan), a prime determinant of contagious caprine pleuropneumonia (CCPP). Extensive biochemical and serological investigations on strain F38 are reported. Some complex serological relationships with other mycoplasma species are revealed. The results, taken in conjunction with earlier published work on geno-typic characters, lead to the conclusion that final classification of these organisms should await further comparative studies of a number of field strains with a related group of strains classified as M. capri-colum.
The characterization of F38 confirms its partial relationship to the “M. mycoides group” of ovine/caprine/bovine mycoplasmas, and has also revealed a very close phenotypic relationship to the bovine mycoplasma serogroup 7, a finding of potential diagnostic and epidemiological importance.
Sammendrag
Artiklen omhandler den taksonomiske placering af den caprine gruppe F38 (MacOwan), en vigtig determinant for smitsom, ondartet lungesyge hos geder (CCPP). Omfattende biokemiske og serologiske undersøgelser af stamme F38 rapporteres. Der findes komplicerede, serologiske relationer til andre arter af mykoplasmer. Resultaterne, sammenstillet med tidligere publicerede arbejder af genetisk karakter, fører til den konklusion, at den endelige klassification af disse mikroorganismer bør afvente udvidede sammenlignende studier af et større antal stammer med en relateret gruppe, klassificeret som M. capri-colum.
Undersøgelscerne af F38 bekræfter dens partielle relation til „M. mycoides gruppen” af ovine, caprine og bovine mykoplasmer. Der ses endvidere et meget naert phaenotypisk slægtskab til bovin gruppe 7, hvilket er af potentiel diagnostisk og epidemiologisk betydning.
