Chemotherapeutic reactions of Chandlerella hawkingi, the filarial parasite of the Indian jungle crow, Corvus macrorhynchos (Agler).

Abstract

1. A high percentage of Indian jungle crows (Corvus macrorhynchos Wagler), found in and around Lucknow, harbour a natural filarial infection Chandlerella hawkingi. The microfilariae of this species are sheathed and show nocturnal periodicity.2. Fourteen compounds active against other kinds of filariae, especially against Litomosoides carinii, were tested against Ch. hawkingi in jungle crows to find whether this infection would be suitable for routine filarial chemotherapy. This is apparently the first report of systematic screening of antifilarial compounds against an avian filariasis.3. Tartar emetic (10 mg/kg intravenously, daily for 6 days) and arsenamide (5 mg/kg intraperitoneally, daily for 6 days) proved to be effective in killing adult worms. Trivalent tryparsamide, though effective, was toxic in the doses tried. Diethylcarbamazine and other compounds tested were ineffective.4. The chemotherapeutic susceptibilities of Ch. hawkingi differ considerably from those of L. carinii and Wuchereria bancrofti.
