    The state of West Bengal, India is endemic for bancroftian filariasis. But no information is available on filarial epidemiology among the tribal population of this state. Filariasis survey was conducted during night covering 1, 386 tribal people of Banpura district, West Bengal. Indoor-resting mosquitoes were collected from human habitations of the tribal areas and dissected. Microfilaria rate, mean microfilarial density, disease rate and endemicity rate were 3.3%, 6.3%, 5.6% and 8.6% respectively. Per man-hour density, infection and infectivity rates of the vector Culex quinquefasciatus were found to be 9.0%, 2.7% and 0% respectively.

    Prevalence of Giardia spp. infection was determined among subjects attending Kochi Medical School Hospital from April 1996 to January 1998. Cysts of Giardia spp. were found in 10 (0.6%) out of 1, 702 stool samples examined. Infection rate was higher among aged males. Most of the subjects with Giardia organisms had no history of traveling overseas except 2 cases. Although source of infection was not determined, most of the positive subjects supposed to be infected within the community.

    Air-dried and powdered seeds of unripe Carica papaya was administered orally at 60 mg/kg/day for 30 days on four pariah dogs naturally infected with Dirofilaria immitis. The treatment resulted in 80% reduction in microfilarial density on day 30 following the onset of treatment. Microfilarial density rose gradually and the level of reduction in the sampling on day 180 was 52%. In vitro, the drug did not produce any lethal effect on the microfilariae of D. immitis. The prolonged maintenance of the reduced level of microfilarial density may be due to the sizeable reduction of adult worm loads.
