| vector control of filariasis in the solomon islands. | in solomon islands, filariasis is caused by the nocturnally perodic form of wuchereria bancrofti and is transmitted by the same vectors of malaria. this study explores the control of this disease as an additional effect of the malaria eradication programme. | 1975 | 3855 |
| theoretical considerations in the vector control of filariasis. | in order to assist in assessing progress of vector control of filariasis a theoretical model is constructed, using retrospective data on infected persons removed to a vector-free situation. this shows that the decrease of microfilaraemia is not regular, but is gradual for the first 3 years and then more rapid, reaching zero at about 10 years. an estimate is made of the level to which the vector must be reduced before transmission of filariasis ceases, showing that the degree of efficiency requir ... | 1975 | 5783 |

| [filarian elephantiasis in french polynesia (wuchereria bancrofti var. pacifica). health study on 274 subjects. i epidemiological and clinical aspects]. | twenty-five years after the fight started against wuchereria bancrofti var. pacifica in french polynesia and which was based upon mass chimiotherapy by diethylcarbamazine (banocide), a survey realized in 1975 and 1976 among 274 patients with elephantiasis allows us to give precise details of the local clinical and epidemiological aspects. since 1950 the number of clinical cases varies along with the parasitological incidence, but with a certain delay which is explained by the late and irreversib ... | 1978 | 385163 |
| [filarian elephantiasis in french polynesia (wuchereria bancrofti var. pacifica). ii. biological aspects]. | realized in french polynesia among 274 patients with elephantiasis, this survey studied the microfilaremia, the eosinophily, the immunoglobulin titers and the antifilarian antibodies (done by passive hemagglutination) for wuchereria bancrofti var. pacifica. patients with elephantiasis seldom have circulating microfilariae in their blood. hypereosinophily is frequent but rarely high. it is similar to the one patients with microfilaremia. there is a trend towards neutropenia during lymphangitic cr ... | 1978 | 385164 |

| bancroftian filariasis: a comparison of microfilariae counting techniques using counting chamber, standard slide and membrane (nuclepore) filtration. | three techniques were compared for counting microfilariae of wuchereria bancrofti in blood specimens--a standard slide method, the counting chamber technique (cct) and a membrane filtration technique (mfct). the cct was much more sensitive than the slide method, the difference in sensitivity between these two methods probably being due mainly to the loss of microfilariae during the dehaemoglobinizing process prior to staining in the standard slide method. there was good correlation between the t ... | 1979 | 393190 |
| preliminary screening of antifilarial activity of levamisole and amodiaquine on wuchereria bancrofti. | a single dose of levamisole of 3 mg/kg had a marked microfilaricidal effect in some persons harbouring wuchereria bancrofti, but there was considerable variation in the response. in some cases blood examinations for microfilariae remained negative or at a low level for several months. persons with high pretreatment microfilaraemias responded less to therapy than did those with low counts. the main side-reaction to levamisole was fever, which began six to eight hours after treatment. combined dec ... | 1979 | 393191 |
| antigenic activity in adult dipetalonema viteae in the indirect immunofluorescent test against sera from filariasis patients--the immunofluorescent histological search for "pure" antigen. | using ifat, it has been shown that isolated egg-shells and uterine fluid of dipetalonema viteae are the most potent antigens in heterologous systems using human sera from patients infected with wuchereria bancrofti, onchocerca volvulus and loa loa, as well as in homologous systems using sera from animals infected with d. viteae. it is suggested that these antigens are unlikely to be highly species-specific, and that anatomical isolation of antigens is a necessary prerequisite to immunochemical a ... | 1979 | 394410 |
| microfilaraemia survey in vientiane, laos. | during the period june 1977-january 1978 a microfilariaemia survey was conducted for the first time in 27 villages (population: 9,300) of vientiane province of laos. a total of 2,339 persons, 1,372 males, 967 females, mostly adults, were blood tested between 2000--2400 hours; one thick smear, approximately 20 c.mm, was collected from each one and stained with 10% giemsa for 30 minutes; only one positive was detected with microfilaria of w. bancrofti in a 22-year-old male; unusually the sheath wa ... | 1979 | 395663 |
