ABSTRACT
A parasitology and clinical survey of Wuchereria bancrofti and Mansonella ozzardi was conducted in Blanchisseuse, an isolated rural community of 650 people in coastal north Trinidad. W. bancrofti microfilariae were found in 15 percent of the resident population and the prevalence was higher in males (19 percent) than in females (12 percent). Microfilaraemias were undetected in children under 5 years of age but 12 percent of children and adolescents between 5 and 19 years of age were positive. Microfilaraemias were most common in males aged 40-59 years (34 percent) and in females in the same age group (21 percent). Whereas geometric mean microfilaria densities were generally higher in females than in males under 40 years old, in the older age groups the pattern was reversed, the difference being especially pronounced in the over sixties. There were more than twice as many males with M. ozzardi microfilariae (35 percent) than there were females (15 percent). The prevalence was low in children and young adults but increased with age thereafter. In the older age groups microfilaria densities followed a similar trend. Genital signs compatiable with lymphatic filarial disease were seen in 29 percent of males; these included hydrocoele (15 percent) and elephantiasis of the scrotum (1 percent). Most signs were seen in persons over 50 years of age. Six per cent of females had lymphoedema of the leg(s), and in four cases (2.3 percent) this had progressed to elephantiasis. A positive association was found between M. ozzardi microfilaraemia and clinical history of articular pain (p<0.001). The findings suggest that both filarial species are some public health significance in at least one rural area in Trinidad, and they provide a basis for the development of a lymphatic filariasis control strategy in the community (AU)
