The susceptibility of BALB/c, C57Bl/6, DBA/2, NMRI, NIH and CD1 mouse strains to experimental
infection with a Venezuelan equine isolate of Trypanosoma evansi was examined through hemoglobin
concentration, packed red cell volume, number of erythrocytes per blood µl, parasitemia, body weight, and
mice survival time. The said variables seem to be suitable markers to contrast the mouse susceptibility to T.
evansi experimental infections. Among the evaluated mouse strains, NMRI was the more susceptible and
DBA/2 the less vulnerable to the local T. evansi isolate used in the study. The resistant mouse strains could
help in the identification of factors conferring natural resistance against T. evansi, while the susceptible could be used to investigate the heterogeneity of virulence observed in this parasite.
