ABSTRACT

A case control study was undertaken in rural areas of Varanasi, U.P., to study the relationship of Culex quinquefasciatus landing on microfilaria--carriers and amicrofilaraemic controls. No statistically significant difference was observed in the vector landing in these two groups.

ABSTRACT

La diagnósis de la Onchocerca volvulus en el Ecuador se basa en la detección de la microfilaria en la piel, en la cual, para realizar la biopsia se usa un punch córneoescleral. Después de la incubación, las microfilarias que emergen son enumeradas y los resultados estandarizados. Otros métodos invasivos no son recomendados para la diagnósis. Un nódulo palpable o la presencia de microfilarias en el ojo, en ausencia de una biopsia positiva en la piel, tienen que ser consideradas en la pauta a seguir para la diagnósis. Futuros descubrimientos son necesarios para hacer de las pruebas serológicas un diagnsotico válido. La prueba de la reacción Mazzotti tiene que estar limitada únicamente a áreas en las cuales la biopsia de la piel es negativa y no hay evidencia de microfilaria en el tejido ocular. El gusano filaria extirpado de pacientes con oncocercosis tiene características de Onchocerca vaolvulus

ABSTRACT

R. sabanus and R. muelleri are very common in the lowland forests of Malaysia. In nature they are infected with Breinlia sp. and D. ramachandrani. In an attempt to determine whether they are also susceptible to subperiodic B. malayi and thereby being potential reservoirs of infection of the disease, 24 R. muelleri and 17 R. sabanus were experimentally infected with the parasite. Results show that although they can support the full development of the parasite, they are poor hosts. This confirms the observation that in Malaysia natural infection of Rattus spp. with the parasite has not been seen. These rats therefore are probably not important in the zoonotic transmission of subperiodic B. malayi in Malaysia.
