| evidence for wolbachia symbiosis in microfilariae of wuchereria bancrofti from west bengal, india. | wolbachia are symbiotic endobacteria that infect the majority of filarial nematodes, including wuchereria bancrofti, brugia malayi and onchocerca volvulus. recent studies have suggested that wolbachia are necessary for the reproduction and survival of filarial nematodes and have highlighted the use of antibiotic therapy such as tetracycline/doxycycline as a novel method of treatment for infections caused by these organisms. before such therapy is conceived and implemented on a large scale, it is ... | 2010 | 20413911 |
