Double infection of Wolbachia and Spiroplasma alters induced plant defense and spider mite fecundity.

Pest Management Science, 2020
BACKGROUND Herbivore-associated bacterial symbionts can change plant physiology and influence the herbivore's fitness. The spider mite Tetranychus truncatus is a notorious pest harboring various bacterial symbionts, however, the effect of bacterial ...

Pathogenicity of Spiroplasma apis and other spiroplasmas for honey-bees in Southwestern France

Annales de l'Institut Pasteur / Microbiologie, 1984
The haemolymph of honey-bees affected by a May disease-like disorder in southwestern France contained numerous spiroplasmas. Further characterization of the organisms and pathogenicity assays showed that the causal agent of the disease was a spiroplasma belonging to group IV. The name Spiroplasma apis was given to the reference strain B31 (ATCC 33834),

Development of Monoclonal Antibodies to Spiroplasmas Utilizing a Mixture of Spiroplasma Citri and Corn Stunt Spiroplasmas

1987
Spleen cells from mice immunized with a mixture of S. citri (M200H) and three strains of corn stunt spiroplasma (F32, PU8–17, I747) were fused with NSI myelomas for the production of monoclonal antibody-secreting hybridomas. Hybridoma supernatants were initially screened against the mixture of spiroplasmas in heterologous double-antibody sandwich ...

MECHANISMS OF SPIROPLASMA PATHOGENICITY

Annual Review of Phytopathology, 1979
Spiroplasmas are helical prokaryotes lacking a rigid cell wall; that is they are mycoplasmas. For plant pathologists the mycoplasma era began in 1966 when Doi and colleagues (28) found by electron microscopy that certain yellows­ diseased plants harbored in their phloem microorganisms indistinguishable from typical mycoplasmas associated with animals ...

Lipid utilization of two flower spiroplasmas and honeybee spiroplasma

Canadian Journal of Microbiology, 1985
A chemically defined medium (CC-494) was used to study the lipid utilization of two flower spiroplasmas (Spiroplasma florkola and SR-3) and honeybee spiroplasma (AS-576). All three spiroplasmas reached comparable growth yields when lauric acid, myristic acid, or stearic acid replaced palmitic acid; palmitoleic acid, linoleic acid, or linolenic acid ...

Spiroplasmas and Acholeplasmas: Multiplication in Insects

Science, 1973
The helical wall-free microorganism, Spiroplasma citri , which is associated with citrus stubborn, a disease with no known vector, multiplied in the leafhopper vector of corn stunt but multiplied to higher titer in the vector of aster yellows and decreased the longevity of that insect.

New Developments in the Culture of Spiroplasma Kunkelii, The Corn Stunt Spiroplasma

1988
Spiroplasma kunkelii, the corn stunt spiroplasma (CSS), is one of several Spiroplasma species that have been isolated from the plant habitat. Of those proven or suspected to be plant pathogenic, S. kunkelii is the most fastidious in its requirements for growth in vitro. S.
