Research progress on intracellular bacteria of the genus Wolbachia

2010 
Intracellular rickettsial bacteria of the genus Wolbachia are found in numerous invertebrates including insects and nematodes. In their insect hosts, Wolbachia often manipulate the reproductive mode of their hosts, causing cytoplasmic incompatibility(CI), parthenogenesis induction(PI), feminization of genetic,or male killing(MK). Many studies have determined that filarial pathogenesis were reliant on this endosymbiont for embryogenesis, growth and survival. Additional researches have also focused on determining the role of Wolbachia in horizontal gene transfer, antiviral responses, potential applications in pest and disease vector control,speciation and so on. This review summarized the significant advances in the study of Wolbachia. Future research directions of this interesting intracellular rickettsial bacteria are also discussed. Key words: Wolbachia;  Symbiosis;  Reproductive manipulation;  Biological control
