UNASSIGNED: Twenty pregnant Yankasa ewes were assigned to three groups to determine the effect of @entity281 on pregnancy. Groups A and B comprising seven ewes each were infected with approximately 1.0  *  10(6) cells of T evansi per ewe through venepuncture at the second and third trimesters of pregnancy, respectively. Group C comprising six ewes served as uninfected control. There was slight pyrexia in the infected groups (groups A and B) but was absent in group C. The mean body weight, @entity413 concentration, and packed cell volume of ewes in group A were not significantly different from those in group C throughout the study. There was also no significant difference in mean @entity413 concentration between groups B and C. However, in group B, mean body weight was significantly (P  <  0.05) lower compared to group C at week 2 and from week 4 post infection (pi) till the end of the study; the packed cell volume also significantly (P  <  0.05) decreased but at weeks 4 and 6 pi. The mean plasma protein of ewes in group A was significantly (P  <  0.05) increased compared to those of group C at weeks 7, 11 pi and thereafter till the end of the study. On the contrary, the plasma protein of ewes in group B decreased significantly (P  <  0.05) compared to those in group C at weeks 2 and 6 pi. There were no reproductive losses throughout the study. This was characterized by insignificant differences in the gestation length between ewes in the infected groups (groups A and B) compared with those in group C. However, there were significant (P  <  0.05) decreases in lamb birth weights of ewes in group B compared with ewes in groups A and C. @entity19 inoculation with blood from infected ewes postpartum was parasitemic 18 to 25  days pi, for ewes in group B, whereas none of the @entity19 in groups A and C were parasitemic. @entity742 born from the infected groups (groups A and B) were also aparasitemic for 40  days postpartum. It was therefore concluded that the T evansi isolate used caused mild trypanosomosis when infected at third trimester, whereas ewes infected at second trimester were resistant.
