Antigenic relatedness between the spiralins of Spiroplasma citri and Spiroplasma melliferum [PDF]

Journal of Bacteriology, 1990
Four spiralins were compared by rocket immunoelectrophoresis, quantitative immunoblotting techniques, and the spiroplasma deformation test with the use of antispiralin (polyclonal) monospecific antibodies. This investigation revealed that the spiralins of Spiroplasma citri and S.

Influences of two coexisting endosymbionts, CI‐inducing Wolbachia and male‐killing Spiroplasma, on the performance of their host Laodelphax striatellus (Hemiptera: Delphacidae)

Ecology and Evolution, 2019
The small brown planthopper Laodelphax striatellus (Hemiptera: Delphacidae) is reported to have the endosymbiont Wolbachia, which shows a strong cytoplasmic incompatibility (CI) between infected males and uninfected females. In the 2000s, female‐biased L.

A Nightmare for Males? A Maternally Transmitted Male-Killing Bacterium and Strong Female Bias in a Green Lacewing Population. [PDF]

PLoS ONE, 2016
For maternally transmitted microbes, a female-biased host sex ratio is of reproductive advantage. Here we found a strong female bias in a field population of the green lacewing, Mallada desjardinsi (Insecta; Neuroptera).

Variable incidence of Spiroplasma infections in natural populations of Drosophila species. [PDF]

PLoS ONE, 2009
Spiroplasma is widespread as a heritable bacterial symbiont in insects and some other invertebrates, in which it sometimes acts as a male-killer and causes female-biased sex ratios in hosts.

A third DNA polymerase from Spiroplasma citri and two other spiroplasmas [PDF]

Journal of Bacteriology, 1982
Recently, two DNA polymerases (ScA and ScB) were isolated and characterized from Spiroplasma citri. We now have found a third DNA polymerase (ScC) not only in S. citri but also in the serologically related honeybee spiroplasma BC3 and the unrelated flower spiroplasma BNR1. Enzyme ScC is N-ethylmaleimide (NEM) sensitive.

Spatio-temporal distribution of Spiroplasma infections in the tsetse fly (Glossina fuscipes fuscipes) in northern Uganda.

PLoS Neglected Tropical Diseases, 2019
Tsetse flies (Glossina spp.) are vectors of parasitic trypanosomes, which cause human (HAT) and animal African trypanosomiasis (AAT) in sub-Saharan Africa.

Cell Division by Longitudinal Scission in the Insect Endosymbiont Spiroplasma poulsonii

mBio, 2016
Spiroplasma bacteria are highly motile bacteria with no cell wall and a helical morphology. This clade includes many vertically transmitted insect endosymbionts, including Spiroplasma poulsonii, a natural endosymbiont of Drosophila melanogaster.

The genome and antigen proteome analysis of Spiroplasma mirum

Frontiers in Microbiology, 2022
Spiroplasma mirum, small motile wall-less bacteria, was originally isolated from a rabbit tick and had the ability to infect newborn mice and caused cataracts. In this study, the whole genome and antigen proteins of S. mirum were comparative analyzed and

Reduced Fecundity Associated with Wolbachia Infection in a Neotropical Drosophilid Redução da fecundidade associada à infecção por Wolbachia em um Drosofilídeo Neotropical

Ecological Entomology, EarlyView.
Using multiple infected and uninfected Drosophila sturtevanti lines, we investigated (i) the impact of Wolbachia on fecundity and (ii) its effects relative to antibiotic treatment. Based on over 1680 dissected ovaries, fecundity was similar between infected and uninfected flies.
