Serum proteins electrophoresis of dromedary in Trypanosoma evansi infections.

One hundred and twenty five dromedaries (Camelus dromedarius) from south Tu nisia, aged 4 to 7 years, were checked for serum proteins by electrophoresi s. The animals were shared into 3 groups on the basis of their status relat ed to trypanosomosis : healhy animals with negative serology for Trypanosom a evansi infection(as tested by indirect immunofluorescence), seropositive animals without clinical signs, and seropositive diseased animals. The anal ysis of the 5 classical seric protein fractions (albium, alpha 1, alpha 2, beta, and gamma globulins) showed hyperprotidemia and increase of the gamma globulins fraction in seropositive animals with or without clinical signs.
