| bancroftian filariasis in togo 1. a comparative field study of the membrane filtration concentration technique and conventional blood films. | the membrane concentration filtration technique which has proved very successful in use in areas of subperiodic filariasis in the pacific, has been used to study an area of nocturnally periodic in togo. the results obtained were similar to those from areas of low endemicity in the pacific. the method was easy to apply under field conditions in africa and the taking of venous blood samples proved competely acceptable to a rural population in south-eastern togo. | 1976 | 781957 |
| a laboratory-based surveillance system for wuchereria bancrofti in togo: a practical model for resource-poor settings. | abstract. one goal of the global program to eliminate lymphatic filariasis (gaelf) is interruption of disease transmission through annual mass drug administration (mda) in areas where lf prevalence is greater than 1%. after mdas are completed, the world health organization (who) recommends a period of passive surveillance before final certification of lf elimination is achieved. guidelines for such a surveillance system have yet to be developed. this paper describes a surveillance system launche ... | 2011 | 21633038 |
| progress toward elimination of lymphatic filariasis --- togo, 2000--2009. | lymphatic filariasis (lf) is a disabling, mosquito-borne disease of humans caused by the parasitic filarial nematodes wuchereria bancrofti, brugia malayi, and brugia timori. in 2000, the global program to eliminate lf (gpelf) was established with the objective of eliminating lf as a public health problem by 2020. at that time, 80 countries had ongoing transmission, with an estimated 1.34 billion persons at risk for infection and 120 million infected. this report describes the lf elimination prog ... | 2011 | 21796097 |
| detection of loa loa-specific dna in blood from occult-infected individuals. | accurate and specific diagnosis of human loiasis is of crucial importance in an endemic area where two-thirds of infected individuals are without circulating microfilariae (occult loiasis). by using the polymerase chain reaction (pcr) and specific primers to the repeat 3 region (15r3) of the gene coding for loa loa 15-kda polyprotein antigen, dna was amplified from total blood lysate of occult-infected subjects. a 396-bp dna fragment was specifically detected. we tested the specificity of this m ... | 1997 | 9225766 |
| a new technique for the determination of microfilarial densities in onchocerciasis. | precise measurement of the parasite load in helminthic infections makes it possible to correlate morbidity, the individual response to treatment, and the best control methods. a membrane filtration technique was recently developed for quantifying wuchereria bancrofti microfilaraemia. the present paper describes its application to onchocerciasis in a study on 107 patients in northern togo. the technique is cheap and simple to apply under field conditions, and is extremely efficient at recovering ... | 1976 | 1085663 |
