[Globular resistance in bovine erythrocytes].
An analysis of red blood cells resistance has been conducted by exposing red corpuscles of zebu, Baoule and metis zebu x Baoule, to different saline concentrations. The statistical results show no sex influence for all breeds. In zebu, there is a difference according to the type of hemoglobin concerned. The last ones differ also from these in taurine and metis. The data analysis were realised by calculating the mean of hemolysis percentages for all samples, as with NaCl concentrations in respect of a 50 per cent hemolysis. These differences can partly explain anaemia in bovine trypanosomiasis to Trypanosoma vivax or T. congolense, which less severely affects taurine Baoule than zebus.
