The endosymbiont Spiroplasma poulsonii increases Drosophila melanogaster resistance to pathogens by enhancing iron sequestration and melanization. [PDF]
mBio, 2023 Facultative endosymbiotic bacteria, such as Wolbachia and Spiroplasma species, are commonly found in association with insects and can dramatically alter their host physiology.

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.

Prospects for the Mechanism of Spiroplasma Swimming [PDF]
Frontiers in Microbiology, 2021 Spiroplasma are helical bacteria that lack a peptidoglycan layer. They are widespread globally as parasites of arthropods and plants. Their infectious processes and survival are most likely supported by their unique swimming system, which is unrelated to

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).

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.

The defensive Spiroplasma. [PDF]
Current Opinion in Insect Science, 2019 Defensive microbes are of great interest for their roles in arthropod health, disease transmission, and biocontrol efforts. Obligate bacterial passengers of arthropods, such as Spiroplasma, confer protection against the natural enemies of their hosts to improve their own fitness.

Arginine Metabolism by Spiroplasma citri [PDF]
Journal of General Microbiology, 1976 METHODS Culture. Spiroplasma citri, little-leaf strain (SP-A), was grown in a basal spiroplasma medium (BSM) containing: 2-1 % (w/v) PPLO broth (Difco), 0.5 % (w/v) yeast extract (Oxoid), I % (w/v) sodium chloride, 15 % (v/v) horse serum no. 6 (Wellcome Reagents Ltd, Beckenham, Kent, heated to 60 "C for 30 min before use), phenol red (10 pg ml-l), 0 ...

A genome sequence survey of the mollicute corn stunt spiroplasmaSpiroplasma kunkelii [PDF]
FEMS Microbiology Letters, 2002 The mollicute corn stunt spiroplasma (Spiroplasma kunkelii) is a leafhopper-transmitted pathogen of maize. Sequencing of the approximately 1.6-Mb genome of S. kunkelii was initiated to aid understanding the genetic basis of spiroplasma interactions with their plant and leafhopper hosts.

Spiroplasmas: evolutionary relationships and biodiversity [PDF]
Frontiers in Bioscience, 2006 Spiroplasmas are wall-less descendants of Gram-positive bacteria that maintain some of the smallest genomes known for self-replicating organisms. These helical, motile prokaryotes exploit numerous habitats, but are most often found in association with insects.
