Maternally transmitted bacteria of the genus Wolbachia are obligate, intracellular symbionts that are frequently found in insects and cause a diverse array of reproductive manipulations, including cytoplasmic incompatibility, male killing, parthenogenesis, and feminization. Despite the existence of a broad range of scientific interest, many aspects of Wolbachia research have been limited to laboratories with insect-rearing facilities. The inability to culture these bacteria outside of the invertebrate host has also led to the existing bias of Wolbachia research toward infections that occur in host insects that are easily reared. Here, we demonstrate that Wolbachia infections can be simply established, stably maintained, and cryogenically stored in vitro using standard tissue culture techniques. We have examined Wolbachia host range by introducing different Wolbachia types into a single tissue culture. The results show that an Aedes albopictus (Diptera: Culicidae) cell line can support five different Wolbachia infection types derived from Drosophila simulans (Diptera: Drosophilidae), Culex pipiens (Culicidae), and Cadra cautella (Lepidoptera: Phycitidae). These bacterial types include infection types that have been assigned to two of the major Wolbachia clades. As an additional examination of Wolbachia host cell range, we demonstrated that a Wolbachia strain from D. simulans could be established in host insect cell lines derived from A. albopictus, Spodoptera frugiperda (Lepidoptera: Noctuidae), and Drosophila melanogaster. These results will facilitate the development of a Wolbachia stock center, permitting novel approaches for the study of Wolbachia infections and encouraging Wolbachia research in additional laboratories.
