| mass chemotherapy with diethylcarbamazine for the control of bancroftian filariasis: a twelve-year follow-up in northern trinidad, including observations on mansonella ozzardi. | a microfilaria survey was conducted in trinidad in 1992, 12 years after mass treatment with spaced doses of diethylcarbamazine citrate (dec-c) for the control of bancroftian filariasis; 348 persons were examined using thick blood smears and a membrane filtration technique. they included 104 who had participated in the mass chemotherapy campaign in 1980. no wuchereria bancrofti microfilariae were detected among 66% of the population examined. in 1980, 86 of 592 persons examined were found to be i ... | 1995 | 7872448 |
| bancroftian filariasis in coastal north trinidad: the effects of mass chemotherapy using spaced doses of diethylcarbamazine citrate on human microfilaraemias and vector infection rates. | the effects of a mass chemotherapy programme using spaced doses of diethylcarbamazine citrate on wuchereria bancrofti microfilaraemias and vector infection rates were studied in an isolated rural community of 650 people in north trinidad where a microfilaria rate of 15% had previously been recorded. a single oral dose of 6 mg/kg body weight was given at monthly intervals for one year. after 6 months, 79% (52/66) of persons previously microfilaraemic had become negative. after 12 months the negat ... | 1987 | 3328349 |
| the prevalence and distribution of mansonella ozzardi in coastal north trinidad, w.i. | a day blood smear survey for mansonella ozzardi in the north coast communities of trinidad recorded a prevalence of 4.8% in 4,488 persons examined. prevalence rates were highest in the four western-most communities, where the vector, culicoides phlebotomus, is a severe nuisance problem. prevalence rates increased with age and were higher in males than in females. mean microfilaria densities were low in both sexes up to 50 years of age but in older males the density increased with age. wuchereria ... | 1979 | 382471 |
| evidence for the interruption of transmission of lymphatic filariasis among schoolchildren in trinidad and tobago. | this study was carried out to provide some evidence for the interruption of transmission of lymphatic filariasis (lf) among schoolchildren in trinidad and tobago. a cross-sectional survey for lf antigenaemia was performed among 63 (13.2%) of the 479 primary schools located in eight administrative (and geographical) regions of trinidad and tobago. from these communities, 2597 schoolchildren aged 6-12 years were sequentially selected for a survey of bancroftian antigenaemia. from each child, 100 m ... | 2004 | 15186935 |
| bancroftian filariasis in coastal north trinidad, west indies: intensity of transmission by culex quinquefasciatus. | the intensity of transmission of wuchereria bancrofti was measured in a coastal community in north trinidad where 15% of the residents were microfilaraemic. the only significant vector, culex quinquefasciatus, was studied in detail to determine seasonal abundance, longevity, infection and infectivity rates. only 2.1% of the indoor biting population and 7.0% of the indoor resting population were infected. the daily mortality rate of the vector increased with age from 27% at four days to 44 to 47% ... | 1981 | 7036432 |
| parasitological and clinical studies of wuchereria bancrofti and mansonella ozzardi in coastal north trinidad, west indies. | a parasitological 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% of the resident population and the prevalence was higher in males (19%) than in females (12%). microfilaraemias were undetected in children under 5 years of age but 12% of children and adolescents between 5 and 19 years of age were positive. microfilaraemias were mo ... | 1982 | 6760556 |
| parasitological, serological, and clinical studies of wuchereria bancrofti in limbe, haiti. | a survey for wuchereria bancrofti in limbe, haiti (est. pop. = 10,500) revealed that 17% (231/1,450) had a patent infection. nearly half of those surveyed harbored fewer than 10 microfilariae (mf) per 20 mm3 of finger-prick blood; the median mf density for females and males was 12.4 and 9.5, respectively. parasitemias occurred as early as age 4. antibody titers greater than or equal to 1:20 against adult d. viteae antigen were observed in 38% of microfilaremic individuals and in 29% of amicrofil ... | 1984 | 6391223 |
