Ochrobacterium teleogrylli

Description and Significance

Ochrobacterium teleogrylli can be plant and animals symbionts, usually this genus is known as opportunistic pathology, however this species is not. (Ryan, M. 2020) Other members of the genus Ochrobacterium are essential for insects such as hessian flies to service on plant seeds. Ochrobacterium teleogrylli is essential for the Teleogryllus Gryllidae crickets to survive in wastelands of China. (Hu, Mengyao et al. 2020)

Genome Structure

Cells are short rod-shaped and are 0.7–0.98×0.93–1.93μm in size. Its is 16S rRNA gene is MK063698.( Hu M, et. al 2020)

Members of the Ochrobacterium have the ability to reduce nitrogen, however this species cannot. However Ochrobacterium Teleogrylli has the ability to hydrolyze gelatin. (Hu M, et. al 2020)

Cell Structure, Metabolism and Life Cycle

Ochrobacterium teleogrylli is gram stain negative, non-spore forming, oxidase- positive, aerobic and motile by means of flagella. (Pembroke, T., 2020)

This strain was isolated from the insect Teleogryllus occipitalis, a cricket found in croplands in China. (Hu M., et al, 2020.) There is not much information about the life cycle and metabolism of this bacterium but hopefully we see developments in research of this microbe.

Ecology and Pathogenesis

This bacterium is known for its ability to degrade pesticides in contaminated croplands. These pesticides include glyphosate, phoxim, chlorpyrifos, Ochrobacterium teleogrylli has been shown to effectively degrade these. (Hu M., et al, 2020)

Ochrobacterium teleogrylli bacterium is found in the insect Teleogryllus occipitalis which is typically found in the Shuangliu district of China. The bacterium were discovered by taking the crickets, crushing them up, and staining them. It is thought that Ochrobacterium teleogrylli and Teleogryllus occipitalis have a mutualistic relationship. The insecticide-degrading bacterium found on the organisms benefit them since it gives the crickets insecticide resistance. (Hu M., et al, 2020)
