Abstract Background Bancroftian filariasis remains endemic in Fiji despite >10 years of mass drug administration (MDA) using diethylcarbamazine and albendazole (DA). The addition ivermectin to this combination (IDA) has improved efficacy microfilarial clearance at 12 months individually randomized trials nocturnal transmission settings, but impact a setting diurnally subperiodic filarial...

A study was conducted to determine the susceptibility of local strains of Culex quinquefasciatus and Aedes aegypti to infection with the strain of Wuchereria bancrofti that occurs in Maceió. State of Alagoas, Brazil. Cx. quinquefasciatus blood fed simultaneously on the same microfilariae carrier ingested more blood and 2-3x more microfilariae than Ae. aegypti. Survival rates of both species of ...

Dirofilariosis caused by the Dirofilaria repens nematodes is widely dispersed in southern Europe, Asia and Africa among dogs, cats, other carnivores and occasionally, humans. The first case of D. repens infection, found in Poland in 2007, concerned humans. In 2009, dirofilariosis was first registered in dogs in 3 focuses in central Poland, Warsaw, Pruszków and Zyrardów, whose range grew conside...

Basophils play a key role in the development and effector phases of type 2 immune responses in both allergic diseases and helminth infections. This study shows that basophils become less responsive to IgE-mediated stimulation when mice are chronically infected with Litomosoides sigmodontis, a filarial nematode, and Schistosoma mansoni, a blood fluke. Although excretory/secretory products from m...

Microfilarial periodic pattern of Wuchereria bancrofti in Kenya was confirmed by the statistical method proposed by Aikat and Das (1977). Fifteen microfilarial positive individuals were brought to Nairobi from Malindi, which is one of the filariasis foci on the coastal area of Kenya. From each individual a 60-microliter finger prick blood film was made every 2 hours throughout one complete 24-h...

although the biology and ecology of the arthropod vectors are different, some factors, such as global warming, the increasing abundance of mosquitoes, the movement of domestic hosts, and the abundance of wild reservoirs, can act as favourable factors for the distribution of infections. the aim of this study was to determine the prevalence of dirofilaria immitis infection in shepherd dogs living...

The effect of aqueous and alcoholic extracts of the leaves of Mallotus philippensis (Lam.) Muell. Arg. was studied on the spontaneous movements of the whole worm and nerve-muscle (n.m.) preparation of Setaria cervi and on the survival of microfilariae in vitro. Both the extracts caused inhibition of spontaneous motility of whole worm and the n.m. preparation of S. Cervi characterized by initial...

The functional symptomatology of loiasis was studied in 101 Congolese subjects living in a village in a highly endemic area. 27.7% of them were carriers of Loa loa microfilariae. 5.9% were infected with Mansonella perstans. No subjects were found to have dermal microfilariae. In anamnesis, 51.5% of them reported episodes of Calabar swellings, 69.3% history of eyeworm and 10.9% episodes of subcu...
