Rapid polyvalent screening for largescale environmental Spiroplasma surveys
نویسندگان
چکیده
Surface serology is an important determinant in Spiroplasma systematics. Reciprocal antigen/antibody reactions between spiroplasmas and individual antisera delineate the 38 described groups and species. However, reciprocal serology is impractical for large-scale studies. This report describes a successful, streamlined polyvalent screening approach used to examine isolates from an environmental survey.

Rapid fluorescence-based screening for Wolbachia endosymbionts in Drosophila germ line and somatic tissues.
Wolbachia is a globally distributed bacterial endosymbiont present in arthropods and nematodes. The advent of sensitive PCR-based approaches has greatly facilitated the identification of Wolbachia-infected individuals and analysis of population infection levels. Here, a complementary visual fluorescence-based Wolbachia screening approach is described. Through the use of the fluorescent dye Syto...
متن کاملPrevalence of a non-male-killing spiroplasma in natural populations of Drosophila hydei.
Male-killing phenotypes are found in a variety of insects and are often associated with maternally inherited endosymbiotic bacteria. In several species of Drosophila, male-killing endosymbionts of the genus Spiroplasma have been found at low frequencies (0.1 to 3%). In this study, spiroplasma infection without causing male-killing was shown to be prevalent (23 to 66%) in Japanese populations of...
متن کاملChemically defined medium for cultivation of several epiphytic and phytopathogenic spiroplasmas.
A chemically defined medium, LD82, was formulated for in vitro cultivation of spiroplasmas. Medium LD82 supported good growth for four epiphytic and insect-pathogenic spiroplasmas, Spiroplasma floricola 23-6, Spiroplasma sp. strain SR3, Spiroplasma sp. strain brevi, and Spiroplasma sp. strain AS576, and of the phytopathogenic spiroplasmas Spiroplasma citri Maroc R8A2 and PC1. Titers of all six ...
متن کاملSpiroplasma symbiont of the pea aphid, Acyrthosiphon pisum (Insecta: Homoptera).
From a laboratory strain of the pea aphid, Acyrthosiphon pisum, we discovered a previously unknown facultative endosymbiotic bacterium. Molecular phylogenetic analysis based on 16S ribosomal DNA revealed that the bacterium is a member of the genus Spiroplasma. The Spiroplasma organism showed stable vertical transmission through successive generations of the host. Injection of hemolymph from inf...
متن کاملMultiple introductions of the Spiroplasma bacterial endosymbiont into Drosophila.
Bacterial endosymbionts are common in insects and can have dramatic effects on their host's evolution. So far, the only heritable symbionts found in Drosophila have been Wolbachia and Spiroplasma. While the incidence and effects of Wolbachia have been studied extensively, the prevalence and significance of Spiroplasma infections in Drosophila are less clear. These small, gram-positive, helical ...
