Spiroplasma as facultative bacterial symbionts of stinkbugs
Many insects are associated with facultative symbiotic bacteria, and their infection prevalence provides an important clue to understand the biological impact of such microbial associates.

Interaction between Spiroplasma and Trypanosoma Prevalence of co-infections The results of the analysis showed that 12.56% of the flies were infected both with Spiroplasma and Trypanosoma, regardless of country, location, and sex. However, the prevalence of single infections of Spiroplasma (35.83%) was higher than that of Trypanosoma (17.46%) (Fig. 4).

The Kinky Propulsion of Spiroplasma [PDF]
Bacteria have evolved many different means of generating movement. In this issue of Cell, Shaevitz et al. (2005) describe the swimming movement of a helical bacterium called Spiroplasma. They discover that Spiroplasma propels itself by generating two temporally distinct kinks that travel the length of the bacterium. These results point to the existence

Spiroplasma Isolated From Third-Generation Laboratory Colony Ixodes persulcatus Ticks
Spiroplasma are vertically-transmitted endosymbionts of ticks and other arthropods. Field-collected Ixodes persulcatus have been reported to harbour Spiroplasma, but nothing is known about their persistence during laboratory colonisation of this tick ...

Male-killing Spiroplasma induces sex-specific cell death via host apoptotic pathway. [PDF]
Some symbiotic bacteria cause remarkable reproductive phenotypes like cytoplasmic incompatibility and male-killing in their host insects. Molecular and cellular mechanisms underlying these symbiont-induced reproductive pathologies are of great interest ...

Spiroplasma membrane lipids [PDF]
Membranes of six spiroplasma strains belonging to different Spiroplasma species and subgroups were isolated by a combination of osmotic lysis and sonication in the presence of EDTA to block endogenous phospholipase activity. Analysis of membrane lipids showed that in addition to free and esterified cholesterol the spiroplasmas incorporated exogenous ...

Tsetse flies (Glossina spp.) house a population-dependent assortment of microorganisms that can include pathogenic African trypanosomes and maternally transmitted endosymbiotic bacteria, the latter of which mediate numerous aspects of their host's ...

Characterization of the recA gene regions of Spiroplasma citri and Spiroplasma melliferum [PDF]
In previous studies (A. Marais, J. M. Bove, and J. Renaudin, J. Bacteriol. 178:862-870, 1996), we have shown that the recA gene of Spiroplasma citri R8A2 was restricted to the first 390 nucleotides of the N-terminal part. PCR amplification and sequencing studies of five additional strains of S.

Nutritional requirements of two flower spiroplasmas and honeybee spiroplasma [PDF]
A chemically defined medium (CC-494) was used to study the nutritional requirements of three spiroplasmas representing three distinct serogroups: flower spiroplasmas [Spiroplasma floricola and FS (SR-3)] and honeybee spiroplasma [HBS (AS-576)]. Glucose, fructose, and mannose were utilized by all three spiroplasmas. In addition, the honeybee spiroplasma

Male-killing bacteria in insects: mechanisms, incidence and implications [PDF]
Bacteria that are vertically transmitted through female hosts and kill male hosts that inherit them were first recorded in insects during the 1950s. Recent studies have shown these "male-killers" to be diverse and have led to a reappraisal of the biology
