Molecular detection of Sodalis glossinidius, Spiroplasma species and Wolbachia endosymbionts in wild population of tsetse flies collected in Cameroon, Chad and Nigeria

BMC Microbiology, 2023
Background Tsetse flies are cyclical vectors of African trypanosomiasis (AT). The flies have established symbiotic associations with different bacteria that influence certain aspects of their physiology.

What Is the Relationship Between Efficacy of Seed Treatment with Insecticides Against <i>Dalbulus maidis</i> (Delong and Wolcott) (Hemiptera: Cicadellidae) Healthy and Infected with Spiroplasm in the Corn Stunt Control? [PDF]

Insects
Seed treatments with insecticides are important tools for managing corn stunting disease complex (CSDC) transmitted by Dalbulus maidis (Hemiptera: Cicadellidae) by reducing the initial leafhoppers’ population and, consequently, the risk of pathogen ...

Spiroplasma infection in Harmonia axyridis - Diversity and multiple infection. [PDF]

PLoS ONE, 2018
The heritable endosymbiotic bacterium Spiroplasma is found in the harlequin ladybird Harmonia axyridis. The proportion of beetles infected with Spiroplasma in different native H. axyridis populations varies from 2% to 49%.

Reconstitution of a minimal motility system based on Spiroplasma swimming by two bacterial actins in a synthetic minimal bacterium

Science Advances, 2022
Motility is one of the most important features of life, but its evolutionary origin remains unknown. In this study, we focused on Spiroplasma, commensal, or parasitic bacteria.

Male-killing mechanisms vary between Spiroplasma species

Frontiers in Microbiology, 2022
Male-killing, a male-specific death of arthropod hosts during development, is induced by Spiroplasma (Mollicutes) endosymbionts of the Citri–Poulsonii and the Ixodetis groups, which are phylogenetically distant groups.

Spiroplasma

, 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 ixodetis Infections in Immunocompetent and Immunosuppressed Patients after Tick Exposure, Sweden

Emerging Infectious Diseases, 2022
We report 2 cases of Spiroplasma ixodetis infection in an immunocompetent patient and an immunocompromised patient who had frequent tick exposure. Fever, thrombocytopenia, and increased liver aminotransferase levels raised the suspicion of anaplasmosis ...

Symbiotic bacteria Sodalis glossinidius, Spiroplasma sp and Wolbachia do not favour Trypanosoma grayi coexistence in wild population of tsetse flies collected in Bobo-Dioulasso, Burkina Faso. [PDF]

BMC Microbiol
Background Tsetse flies, the biological vectors of African trypanosomes, have established symbiotic associations with different bacteria. Their vector competence is suggested to be affected by bacterial endosymbionts.

Isolation and structure of the fibril protein, a major component of the internal ribbon for Spiroplasma swimming

bioRxiv, 2022
Spiroplasma, which are known pathogens and commensals of arthropods and plants, are helical-shaped bacteria that lack a peptidoglycan layer. Spiroplasma swim by alternating between left- and right-handed helicity.

Male-killing Spiroplasma induces sex-specific cell death via host apoptotic pathway. [PDF]

PLoS Pathogens, 2014
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 ...
