Abstract

Summary: A new Mycoplasmatales virus, referred to as MV-O1, was isolated during cloning of 19L. The virus formed plaques only on strains of , i.e. the original clone, 19L, a subclone of 19L (-i), Goat 5 and a wild isolate (K-2) of , but not on other acholeplasmas, including strains of , nor on five human mycoplasma species tested. The virus required horse serum for multiplication as well as for plaque formation and passed through a 100 nm filter. Electron microscopy revealed enveloped, spherical particles 80-130 nm in diameter. The buoyant density of purified virus was 1.23 g ml in CsCl, and agarose gel electrophoresis indicated that the viral nucleic acid was DNA.
