Abstract

Onchocerca volvulus is a tissue-dwelling, vector-borne nematode parasite of humans and is the causative agent of onchocerciasis or river blindness. Natural infections of BALB/c mice with Litomosoides sigmodontis and of cattle with Onchocerca ochengi were used as models to study the immune responses ...

Abstract

Eighteen cows naturally infected with Onchocerca gutturosa were divided into 3 groups. Group A (n = 10) was given Ivomec (1% ivermectin) sc at 200 µg/kg bwt, group B (n = 5) was given diethylcarbamazine orally at 50 mg/kg bwt daily for 2 days, and group C served as controls. Before treatment and in ...

Abstract

Of 6 anthelmintics tested against natural Onchocerca lienalis infections in groups of 7-10 cattle on farms in the Bryansk region, Russia, levamisole at 15 mg/kg bwt given twice and furazolidone at 25 mg/kg given twice were 51% effective against the microfilariae. Three doses of 50 mg/kg Panacur...

Abstract

Tests undertaken in 1984 in the USSR on 52 cows with natural Onchocerca infections, showed that 1% solutions of Ivomec [ivermectin], administered subcutaneously at 0.2 or 0.3 mg/kg bwt as a single injection or twice at a 24 h interval, were 100% effective. The filaricidal effect persisted for 6...

Abstract

Umbilical hides from 536 dairy cattle in Minnesota, USA, were tested for the microfilarial stage of Onchocerca species to determine the distribution of onchocerciasis in the state. The infection was widespread as microfilariae were obtained from 214 (40%) of the animals, representing nearly all...

Abstract

Of 438 umbilical and cervical skin samples from freshly slaughtered cattle killed at an abattoir in Tübingen, Germany, 40.4% contained microfilariae. It was not possible to determine whether the animals were infected with O. gutturosa, O. lienalis or both, by microfilarial morphology alone. The...

Abstract

Umbilical skin samples (20×40 cm) from 291 pasture cattle were examined for microfilariae (mf) at an abattoir in Tübingen, Germany, over 12 months. Onchocerca mf were found in 41% of samples. The distribution of mf was assessed by the collagenase technique and in histological sections. About half...

Abstract

After a discussion of the incidence of Onchocerca in bovines, the authors describe the presence of numerous onchocerci in fibrous nodules in the umbilicus of a wild buffalo. No microfilariae were found. The parasite was provisionally grouped as O. gibsoni from its structure, although the nodule...
