Nonrequiring Member of the Mycoplasmatales

چکیده
Mycoplasmas recovered from tissue cultures and previously shown to belong to the sterol-nonrequiring group of mycoplasmas have been further characterized. The biological and serological properties of these strains show them to be clearly distinct from Acholeplasma laidlawii and A. granularum, two species of sterol-nonrequiring mycoplasmas recently reclassified. It is proposed that the newly described mycoplasmas be designated Acholeplasma axanthum, sp. n.

Characteristics of a new sterol-nonrequiring Mycoplasma.
Two Mycoplasma strains recovered from tissue culture environments were found to grow in complex media devoid of serum or serum fractions containing cholesterol and in a cholesterol-free synthetic medium. Neither strain was capable of synthesizing pigmented carotenoids, although these compounds are present in, and characteristic of, other sterol-nonrequiring mycoplasmas. Serological tests and an...
متن کاملCholesterol incorporation into bacterial membranes.
The wall-covered bacteria Micrococcus lysodeikticus, Bacillus megaterium, and Proteus mirabilis incorporated exogenous cholesterol into their cytoplasmic membrane in quantities resembling those incorporated by sterol-nonrequiring mycoplasmas. Cholesterol incorporation into the outer membrane of P. mirabilis was much more restricted than into the cytoplasmic membrane.
متن کاملOrigins of the mycoplasmas: sterol-nonrequiring mycoplasmas evolved from streptococci.
We report the establishment of a phylogenetic relationship between the sterol-nonrequiring mycoplasmas (Acholeplasma species) and streptococci. Three specific antisera prepared against purified Streptococcus faecalis fructose diphosphate aldolase and glyceraldehyde-3-phosphate dehydrogenase and Pediococcus cerevisiae glyceraldehyde-3-phosphate dehydrogenase were used for comparative enzyme immu...
