Leucogram in heifer sand calves (Holstein) infected with a venezuelan strain of Trypanosoma vivax

This work had as objective the evaluation of the leucogram in Holstein heifers and calves experimentally infected with a Venezuelan strain of Trypanosoma vivax. The dates were analysed by the Mann-Whitney non-parametric test. The total means comparation of leucocytes in heifers was statistically significative (P < 0.05). The calves produced a neutrophilia when compared the total means for the infected and control groups (P < 0.05). The totals means of linphocytes and monocytes were statistically significative (P < 0.05).Este trabajo tuvo como objetivo la evaluación del leucograma en novillas y becerros Holstein infectados experimentalmente con una cepa venezolana de Trypanosoma vivax. Los datos fueron analizados a través de la prueba no paramétrica de U de Mann-Whitney. La comparación de las medias de los numeros totales de los leucocitos (NTL) en las novillas, fue estadísticamente significativo (P < 0,05). Los becerros presentaron neutrofilia al compararse las medias totales del grupo infectado y control (P < 0,05). Los promedios totales de los linfocitos y monocitos en las novillas y becerros, fueron estadísticamente significativos (P < 0,05).This work had as objective the evaluation of the leucogram in Holstein heifers and calves experimentally infected with a Venezuelan strain of Trypanosoma vivax.
