BACKGROUND Onchocerciasis is the world's second leading infectious cause of blindness. Its control is currently hampered by the lack of a macrofilaricidal drug and by severe adverse events observed when the lone recommended microfilaricide, ivermectin is administered to individuals co-infected with Loa loa. Therefore, there is the need for a safe and effective macrofilaricidal drug that will be...

To evaluate the impact of onchocerciasis control programmes on the annual transmission potential, it is customary to monitor the man-biting rate of vector Siniuliuin (Diptera: Simuliidae) and the number of Oizclzocerca (Nematoda: Onchocercidae) infective larvae found in them (Walsh et al., 1978). In addition to the transmission of Onchocerca volvulus (Leuckart) causing human onchocerciasis, Sim...

Onchocerca ochengi, a filarial parasite of cattle, represents the closest relative of the human pathogen, Onchocerca volvulus. Both species harbour Wolbachia endosymbionts and are remarkable in that adult female worms remain viable but sessile for many years while surrounded by host cells and antibodies. The basis of the symbiosis between filariae and Wolbachia is thought to be metabolic, altho...

Onchocerca lupi infection is reported primarily in symptomatic dogs. We aimed to determine the infection in dogs from areas of Greece and Portugal with reported cases. Of 107 dogs, 9 (8%) were skin snip-positive for the parasite. DNA sequences of parasites in specimens from distinct dog populations differed genetically from those in GenBank.

Onchocerciasis (river blindness) is a major parasitic disease of humans in sub-Saharan Africa caused by the microfilarial stage of the nematode Onchocerca volvulus. Using Onchocerca ochengi, a closely related species which infects cattle and is transmitted by the same black fly vector (Simulium damnosum sensu lato) as O. volvulus, we have conducted longitudinal studies after either natural fiel...

This report deals with the effect of the mode of feeding of the hindgut-fermenting herbivorous rhinoceros on the species of Protozoa fermenting the ingesta, as demonstrated by the proposed three new species of ciliated Protozoa: Didesmis synciliata differing from D. ovalis in having syncilia in place of simple cilia, Blepharoconus dicerotos being twice the size of B. cervicalis, and Blepharosph...
