Two immunoglobulin G enzyme-linked immunosorbent assay (ELISA) versions using whole promastigotes of Leishmania infantum (syn. Leishmania chagasi) treated either with β-mercaptoethanol (β-ME-ELISA) or trypsin (TRYP-ELISA) as antigens were developed for the diagnosis of canine visceral leishmaniasis (CVL). By comparison with the direct agglutination test (DAT; 100%, 31/31; 95% confidence interval [CI]: 86.3–100%...
Abstract Objectives: During summer in Mediterranean regions, well adapted native cattle breeds present differences in environmental tolerance. The objective of this study was to compare heat tolerance of Alentejana and Mertolenga heifers under direct solar radiation, by quantifying the pathways of evaporative thermolysis and thermostability. Materials and Methods: The experiment was carried out in 5 days. 6 Ale...
O presente estudo teve como objectivo avaliar, em duas raças de bovinos, o comportamento das vias de termólise latente, perante aumentos planeados da temperatura ambiente. Foram utilizados 6 novilhas das raças Frísia e 6 da raça Mertolenga com pesos médios de 403,8±15,5kg e 308,2±31,2Kg, respectivamente. O estudo foi realizado em câmara climática e decorreu durante 12 dias, dividido em 4 fases, cada uma com a d...
