Arthropod-transmitted (filarial) nematodes are important causes of disease in humans in tropical countries, yet no safe drug appropriate for mass delivery kills the adult worms. However, most filarial nematodes contain rickettsia-like bacteria of the genus Wolbachia, and related bacteria also occur in insects. There is increasing evidence that these bacteria have significant functions in the biology of filarial nematodes, They are thus important targets in the search for antifilarial drugs and experiments in animals and humans have suggested that antibiotic therapy has potential in treating filarial infections. To optimize future clinical trials there is a need for a fast and simple in vitro drug screen to compare drug efficacies against Wolbachia, In the absence of Wolbachia-infected nematode cell lines, we have utilized an Aedes albopictus insect cell line, naturally infected with Wolbachia, to test the activity of antimicrobial agents. Of the five antibiotics tested, doxycycline, oxytetracycline and rifampicin showed good activity (MICs of 0.0625, 4 and 0.0625 mg/L, respectively) whereas ciprofloxacin and penicillin were shown to have no effect.
