In ultrastructural studies, individual cells varied in diameter from 300 to 1200 nm, were surrounded by a cytoplasmic membrane and showed no evidence of cell wall. The organisms were readily filterable through membrane filters with mean pore diameters of 450 and 300 nm, with unusually large numbers of organisms filterable through 200 nm pore membrane filters. Growth occurred over a temperature range of 15–32 °C with optimum growth at 30 °C. The organism fermented glucose and hydrolysed arginine but did not hydrolyse urea. Strain BARC 318T was insensitive to 500 U penicillin ml–1 and required serum or cholesterol for growth. It was serologically distinct from all currently described sterol-requiring, fermentative Mycoplasma species and from 12 non-sterol-requiring Mesoplasma species, 13 non-sterol-requiring Acholeplasma species and 5 previously described sterol-requiring Entomoplasma species. Strain BARC 318T was shown to have a G+C content of 34 mol% and a genome size of 870 kbp. The 16S rDNA sequence of strain BARC 318T was compared to 16S rDNA sequences of several other Entomoplasma species and to other representative species of the genera Spiroplasma and Mycoplasma, and to other members of the class Mollicutes. These comparisons indicated that strain BARC 318T had close phylogenetic relationships to other Entomoplasma species. On the basis of these findings and other similarities in morphology, growth and temperature requirements and genomic features, the organism was assigned to the genus Entomoplasma. Strain BARC 318T (ATCC 51999T) is designated the type strain of Entomoplasma freundtii sp. nov.", }
