The genus Spiroplasma and its non-helical descendants: phylogenetic classification, correlation with phenotype and roots of the Mycoplasma mycoides clade.
The genus Spiroplasma (helical mollicutes: Bacteria: Firmicutes: Mollicutes: Entomoplasmatales: Spiroplasmataceae) is associated primarily with insects. The Mycoplasma mycoides cluster (sensuExpand
Nucleotide sequence of the Spiroplasma citri fibril protein gene.
Electron microscopic observation of spiroplasmas lysed by detergent (sodium deoxycholate) revealed the release of bundles of fibrils from the cells. Individual fibrils are 4 nm in diameter andExpand
Spiroplasma poulsonii sp. nov., a new species associated with male-lethality in Drosophila willistoni, a neotropical species of fruit fly.
Progenies from some wild-caught females of Drosophila willistoni and three other sibling species are entirely female. The proclivity for production of unisexual female progeny by these flies wasExpand
Pathogenic mycoplasmas: cultivation and vertebrate pathogenicity of a new spiroplasma.
A spiroplasma recovered from allantoic fluids of chick embryos infected with the tick-derived suckling mouse cataract agent was grown in continuous passage on a new artificial culture medium. TheExpand
Cultivation of the Drosophila Sex-Ratio Spiroplasma
Uncultivable for more than 25 years, the sex-ratio spiroplasma of Drosophila willistoni grew in a tissue culture medium (H-2) containing an embryo-derived lepidopteran cell line (IPLB-TN-R2). AfterExpand
Suckling mouse cataract agent is a helical wall-free prokaryote (spiroplasma) pathogenic for vertebrates
THE suckling mouse cataract agent (SMCA) is a filterable organism originally isolated from a pooled extract of rabbit ticks (Haemaphysalis leporis-palustris) collected near Atlanta, Georgia in AprilExpand
Spiroplasma melliferum, a New Species from the Honeybee (Apis mellifera)
Twenty-eight strains of spiroplasma subgroup I-2 isolated from insects and flower surfaces were similar in their serological properties. Strain BC-3T (T = type strain), which was isolated from theExpand
Revised Group Classification of the Genus Spiroplasma (Class Mollicutes), with Proposed New Groups XII to XXIII
Fourteen spiroplasma strains, primarily of insect origin, were analyzed according to criteria previously proposed for description of new serogroups of the genus Spiroplasma. When tested by reciprocalExpand
The spiroplasma deformation test, a new serological method
The deformation test is a simple and highly sensitive technique capable of demonstrating significant antigenic differences among helical, wall-less prokaryotes (spiroplasmas). Specific identified.Expand
