Morphological and sequence analysis of Mycoplasma sp. isolated from the oral cavity of a house musk shrew (Suncus murinus).

Mycoplasma sp. strain EDS-4 was isolated from the oral cavity of EDS line of a house musk shrew (Suncus murinus) originated from Bangladesh, and was distinguished from all previously described mollicutes. It lacks a cell wall; ferments glucose; does not produce film and spots; and does not hydrolyse arginine and urea. The strain could be distinguished from all previously described mollicutes by 16S rRNA gene sequence comparisons. The results suggest that the isolate is new species of mollicutes originated from the shrew. The strain EDS-4 has been deposited with Japan collection of Microorganisms, Bioresource Center, RIKEN in Japan (JCM15930). The 16S rRNA gene sequence of strain EDS-4 is available through the DDBJ under accession number (AB469852).
