A mycoplasma designated strain 1219T (T, type strain) was isolated from the phallus of a gander in Hungary. It was assigned to the class Mollicutes, order Mycoplasmatales, on the basis of morphological, cultural, and physical studies. The base composition of its deoxyribonucleic acid was 25 mol% guanine plus cytosine. It was dependent on sterol for growth, and its growth was inhibited by digitonin. The organism was assigned to the genus Mycoplasma since it did not hydrolyze urea and there was no evidence of helical forms. It hydrolyzed arginine, but other biochemical tests were negative. Strain 1219T could not be identified as any of 77 accepted Mycoplasma species by growth inhibition, immunofluorescence, or metabolism inhibition tests and thus appeared to be a new species. We propose the name Mycoplasma anseris for this organism, for which the type strain is strain 1219.
