Abstract

Wolbachia pipientis is an obligately intracellular bacterium infecting a number of arthropod and nematode species. At the body level, Wolbachia infection may cause parthenogenesis, feminization of genetic males, male killing, or cytoplasmic incompatibility; it may also be asymptomatic. Of special interest is DNA transfer from Wolbachia to the host insect genome, which was discovered recently. At the cellular level, the effects caused by Wolbachia have been studied more poorly. Only one of the known insect cell lines has been obtained from an insect species (the mosquito Aedes albopictus) infected by Wolbachia. In this study, a continuous cell line Dm2008Wb1 has been obtained from embryos of Drosophila melanogaster infected under natural conditions. Wolbachia both persists in a primary cell culture and is retained upon its transformation into a continuous culture. The presence of this bacterium in cells in a free form is evidenced by the fact that tetracycline treatment can cure the cells of Wolbachia and by successful transfer of Wolbachia to another cell line (S2), where it has not been detected before.
