    The relationship between decrease in feed intake and infection with trypanosoma congolense and T. vivax in West African dwarf goats
    (Taylor & Francis, 1993-03-01) Wassink, G. J.
    Twenty-three mature dwarf goats were used to study whether there is a relationship between the decrease in feed intake for individual goats and infection with T.congolense and T. vivax. Furthermore, it was investigated how rectal temperatures and blood parameters were affected by the T. congolense infection and how changes in these parameters can be used to predict the effect of a T. vivax infection on feed intake. For individual goats a ranking correlation was found between relative dry matter intake and infection (r = 0.59; p < .05). Animals with the most marked decrease in dry matter intake during the T. congolense infection showed a smaller increase in urea and a higher increase in non esterified fatty acids and beta-hydroxy butyrate levels in their blood. Evidence was obtained that the relative decrease in dry matter intake for individual goats during a T. vivax infection can be predicted on the basis of urea and creatinine responses measured in the blood during a previous infection with T. congolense infection.

    Inland valley swamp rice development: Malaria, schistosomiasis, onchocerciasis in South Central Sierra Leone
    (Elsevier BV, 1994-03-01) Gbakima, A A
    The prevalence of malaria, schistosomiasis and onchocerciasis was determined in 1,106 residents of five villages in the Moyamba District, Southern Sierra Leone, to determine whether inland valley swamp (IVS) development was associated with changes in the prevalence of malaria, schistosomiasis and onchocerciasis in these villages. These parasitic diseases were studied in four villages receiving IVS, Food and Agricultural Organization (FAO) assistance and in one village not receiving FAO assistance. Malaria was the most prevalent infection, detected in 42.6% of the persons examined, followed by O. volvulus (17.7%), S. haematobium (0.6%) and S. mansoni (0.3%). Plasmodium falciparum accounted for 90.4% of the malaria infections, followed by P. malaria (2.1%), P. ovale (0.5%), and mixed infections (7.0%). The trend of infection to O. volvulus increased significantly with an increase in age. S. haematobium (0.6%) and S. mansoni (0.3%) infections were low and no Biomphalaria pfeifferi and Bulinus globosus were found in 33 IVS development swamps examined. These data indicate that IVS development is associated with an increase in the prevalence of malaria infection, but not in the prevalence of O. volvulus, S. haematobium and S. mansoni.
