Humoral immune responses against filarial parasitic infection were studied in 62 cases of acute filarial disease presenting with filarial fever with adenolymphangitis, in a community where Bancroftian filariasis was endemic, during and about one month before and after the febrile episode. Their
Vector-borne diseases transmitted by mosquitoes cause globally important diseases such as malaria, dengue fever, and filariasis. The incidence of these diseases can be reduced through mosquito control programs but these control programs currently rely on synthetic insecticides that can impact the
Comparative larvicidal efficacy of aqueous and organic solvent extracts from seeds, leaves and flowers of three desert plants viz. Calotropis procera (Aiton), Tephrosia purpurea (L.) Pers. and Prosopis juliflora (Sw.) DC. was evaluated against Anopheles stephensi (Liston), Aedes aegypti (Linnaeus)
Essential oils of four species and two hybrid varieties of Cymbopogon grasses were evaluated for their repellent properties against the major vector mosquitoes, namely, Anopheles stephensi, Culex quinque-fasciatus and Aedes aegypti, both in laboratory and field. The magnitude of repellency in the
The present study was aimed to find the larvicidal activity of petroleum ether, chloroform, acetone and methanolic extracts of Dichanthium foveolatum (Del.) Roberty, Leptochloa uniflora Hochst, Pancratium triflorum Roxb and Molineria trichocarpa (Wight) N.P.Balakr against Culex BACKGROUND
Rapidly increasing temperatures in the mountain region of Nepal and recent reports of dengue fever and lymphatic filariasis cases from mountainous areas of central Nepal prompted us to study the spatio-temporal distribution of the vectors of these two diseases along an altitudinal
An attempt was made to identify the filarial specific antigens that are capable of inducing immune response in human filariasis. Lymphocytes were taken from three clinically defined groups living in an endemic area in Madras, namely microfilaraemic (MF) subjects with microfilariae in their blood
BACKGROUND
The term filariasis comprises a group of parasitic infections caused by helminths belonging to different genera in the superfamily Filaroidea. The human parasites occur mainly in tropical and subtropical regions, but filariae are also found in temperate climates, where they can infect
Seventy-three asymptomatic bancroftian filariasis patients with positive microfilaria in their blood films were included. The patients were randomly divided into 2 groups: ivermectin group (50 cases) given 2 doses each of 100 ug/kg body weight, 3 months apart, and 23 cases had 2 doses of placebo.
BACKGROUND
Filariasis is an endemic disease with worldwide distribution in tropical and subtropical regions. It is uncommon in Qatar. The conventional diagnostic procedure is the demonstration of microfilaria in blood smears. Even with its high incidence, it is unusual to detect microfilaria in fine
To evaluate the efficacy and longitudinal effect of two single (100 micrograms/kg) doses of ivermectin, 3 months apart, 240 asymptomatic male subjects from 2 endemic Egyptian villages were enrolled in a one-year double-blind study. Subjects aged 15-55 years were randomly assigned placebo (40) or
Mansonella perstans is a human filarial parasite distributed across the center of Africa and equatorial America. Although M. perstans infection is asymptomatic in most individuals, a variety of symptoms have been described, including angioedema, pruritus, fever, ocular involvement, and serous
Culex quinquefasciatus (Diptera: Culicidae) is a vector of many pathogens and parasites of humans, as well as domestic and wild animals. In urban and semi-urban Asian countries, Cx. quinquefasciatus is a main vector of nematodes causing lymphatic filariasis. In the African region, it vectors the
