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 ...

Investigation of vertical and horizontal transmission of Spiroplasma in ticks under laboratory conditions [PDF]

Scientific Reports, 2023
Many arthropods harbour bacterial symbionts, which are maintained by vertical and/or horizontal transmission. Spiroplasma is one of the most well-known symbionts of ticks and other arthropods. It is still unclear how Spiroplasma infections have spread in

Endosymbiotic Bacteria Spiroplasma and Wolbachia in a Laboratory-Reared Insect Collection [PDF]

Insects
Many insect and other arthropod species are maintained as non-model laboratory stocks and are used for fundamental and applied studies. Their biology may be affected by symbionts, such as Wolbachia and Spiroplasma.

What Is the Relationship Between Efficacy of Seed Treatment with Insecticides Against Dalbulus maidis (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 ...

The endosymbiont Spiroplasma poulsonii increases Drosophila melanogaster resistance to pathogens by enhancing iron sequestration and melanization [PDF]

mBio
Facultative endosymbiotic bacteria, such as Wolbachia and Spiroplasma species, are commonly found in association with insects and can dramatically alter their host physiology.

In Vitro Culture of the Insect Endosymbiont Spiroplasma poulsonii Highlights Bacterial Genes Involved in Host-Symbiont Interaction

mBio, 2018
Endosymbiotic bacteria associated with eukaryotic hosts are omnipresent in nature, particularly in insects. Studying the bacterial side of host-symbiont interactions is, however, often limited by the unculturability and genetic intractability of the ...

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 Microbiology
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.

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
