Abstract

A study was carried out to determine whether the trichostrongyle parasites of sheep and goats on a government research station in North-West Cameroon had become resistant to benzimidazole anthelmintics, following the routine use of thiabendazole at monthly intervals for several years. The number of ...

Abstract

Quantitative and qualitative differences in both the macro- and microfilariae (mff) of O. ochengi were studied in relation to age in naturally infected cattle. Autochthonous cattle at a site on the Adamawa plateau, North Cameroon, situated near a perennial Simulium damnosum s.l. breeding site, were ...

Abstract

In an onchocerciasis endemic area in Cameroon, 117 Zebu calves one to 24 months old, were examined in January 1993 for palpable Onchocerca ochengi nodules and microfilariae in skin snips. A highly infected bait oxen was used for the production of infective larvae through the vector Simulium...

Abstract

Mast cells and their association with other inflammatory cells were studied using immunohistology in 5 animal species of Onchocerca (O. gutturosa, O. ochengi and O. gibsoni from cattle in Uganda, Cameroon and Queensland, Australia, respectively, and O. tarsicola and O. flexuosa from deer in...

Abstract

The distributions of the microfilaricide, ivermectin, and the partial macrofilaricide, suramin, in plasma, skin, nodule capsules and nodule contents were determined in cattle naturally infected with Onchocerca ochengi in Cameroon. The cattle were treated with either a single, sc injection of 500 µg ...

Abstract

In north Cameroon, where both O. ochengi and O. volvulus are endemic, a field study was conducted to examine to what extent the transmission of the 2 parasite species overlap and what influence this has on the epidemiology of human onchocerciasis. Experiments were carried out to determine which of...

Abstract

The efficacy of ivermectin as a prophylactic drug against naturally transmitted Onchocerca ochengi infections in cattle was investigated in a controlled, prospective study in northern Cameroon. Calves were treated monthly with ivermectin at either 200 µg/kg or 500 µg/kg for 21 months. None of 15...

Abstract

Cooperia pectinata and C. punctata are considered by many authors to be found exclusively in the intestine. Nevertheless, some limited surveys have reported their presence in the abomasum. This survey was carried out on 17 zebu cattle in a slaughterhouse in northern Cameroon and confirms the...

Abstract

The African bovine parasite Onchocerca ochengi is used as a chemotherapeutic model for the human parasite O. volvulus, for which there is no safe and effective drug lethal to adult worms. It is now reported that oxytetracycline is macrofilaricidal against O. ochengi. In a controlled trial in...

Abstract

Background: Recent reports of transmission interruption of Onchocerca volvulus, the causing agent of river blindness, in former endemic foci in the Americas, and more recently in West and East Africa, raise the question whether elimination of this debilitating disease is underway after long-term...
