Isolation and Characterization of Mycoplasma columbinum and Mycoplasma columborale, Two New Species from Pigeons

Abstract
Eighteen arginine-positive and 32 glucose-fermenting Mycoplasma strains were isolated from tracheas and oropharynxes of pigeons. Biochemical and serological studies revealed that these isolates were distinguished from all of the currently accepted Mycoplasma species and serogroups. The 18 arginine-positive pigeon strains appear to constitute a new species, for which the name Mycoplasma columbinum is proposed. The type strain of M. columbinum is MMP1 (= ATCC 29257 = NCTC 00000). The 32 glucose-fermenting pigeon strains constitute another new species, for which the name Mycoplasma columborale is proposed. The type strain of M. columborale is MMP4 (= ATCC 29258 = NCTC 00000).
