Differential gene expression in a tripartite interaction: Drosophila, Spiroplasma and parasitic wasps [PDF]
PeerJ, 2021 Background Several facultative bacterial symbionts of insects protect their hosts against natural enemies. Spiroplasma poulsonii strain sMel (hereafter Spiroplasma), a male-killing heritable symbiont of Drosophila melanogaster, confers protection against

The toxins of vertically transmitted Spiroplasma
Frontiers in Microbiology, 2023 Vertically transmitted (VT) microbial symbionts play a vital role in the evolution of their insect hosts. A longstanding question in symbiont research is what genes help promote long-term stability of vertically transmitted lifestyles.

Microorganisms, 2021 Members of the genus Spiroplasma are Gram-positive bacteria without cell walls. Some Spiroplasma species can cause disease in arthropods such as bees, whereas others provide their host with resistance to pathogens.

Nutritional requirements of two flower spiroplasmas and honeybee spiroplasma [PDF]
Journal of Bacteriology, 1983 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

Integrative and free Spiroplasma citri oriC plasmids: expression of the Spiroplasma phoeniceum spiralin in Spiroplasma citri [PDF]
Journal of Bacteriology, 1995 The replication region (oriC) of the Spiroplasma citri chromosome has been recently sequenced, and a 2-kbp DNA fragment was characterized as an autonomously replicating sequence (F. Ye, J. Renaudin, J. M. Bové, and F. Laigret, Curr. Microbiol. 29:23-29, 1994).

, 2023 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).

Spiroplasma membrane lipids [PDF]
Journal of Bacteriology, 1985 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 ...

Multiple Origins and Specific Evolution of CRISPR/Cas9 Systems in Minimal Bacteria (Mollicutes)
Frontiers in Microbiology, 2019 CRISPR/Cas systems provide adaptive defense mechanisms against invading nucleic acids in prokaryotes. Because of its interest as a genetic tool, the Type II CRISPR/Cas9 system from Streptococcus pyogenes has been extensively studied. It includes the Cas9

The Kinky Propulsion of Spiroplasma [PDF]
Cell, 2005 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
