Heads or tails: host-parasite interactions in the Drosophila-Wolbachia system

Article Abstract:

The density and distribution of a variety of bacterial strains infecting six Drosophila species and the several aspects of Wolbachia-host interactions are described. Comparing the properties of a single Wolbachia strain in different host backgrounds and the properties of different Wolbachia strains in the same host background, it has been shown that bacterial factors determine distribution, while bacterial density seems to be limited by the host.

Wolbachia transfer from Rhagoletis cerasi to Drosophila simulans: investigating the outcomes of host-symbiont coevolution

Article Abstract:

Results reveal that between the two Wolbachia variants one does not develop in the host while the other establishes in the host. However transmission rates of the latter Wolbachia variant are low and show negative infection fitness effects. Data point out that neither of the variants can be naturally maintained in Drosophila simulans.

Evolutionary dynamics of wAu-like Wolbachia variants in neotropic Drosophila spp

Article Abstract:

A study was conducted on the Wolbachia bacteria, which are common intracellular bacterial symbionts of arthropods, of neotropical Drosophila species. Possible evolutionary scenarios reconstructing the infection history of wAu-like Wolbachia in neotropical Drosophila species and the old world species D. simulans are discussed.
