Sažetak
Experiments were carried out on twelve young zebu cattle (Bos indicus) aged from 12 to 18 months, divided into 3 groups of 4 animals. Following experimental infection with Samaru strain of Trypanasoma vivax, parasitemia and serum, biochemical values - bilirubin, glucose, and blood urea nitrogen (BUN) and aspartate serum transaminase (AST) - were monitored in all groups. The strain of T. vivax used caused an acute infection, with parasites appearing in circulation on day 2 with infection and peaking on day 5 post-infection (p.i.). However, parasites disappeared from circulation on day 7 p.i. only to reappear, with a second peak occurring on day 13 p.i. In the group infused with lactose, parasitemia persisted without apparent remission until day 13 p.i. when the experiment was terminated. The effects of T. vivax on biochemical values of infected animals (group B) indicated significant increases (P<0.05) on serum glucose and bilirubin levels following first peak of parasitemia, while serum BUN and AST showed significantly (P<0.05) low levels after first peak of parasitemia, remaining low thereafter until the end of the experiment. This situation was ascribed to possible cellular or organ damage following the peak parasitemia earlier observed. Lactose in saline infusion at peak parasitemia in group C animals caused normal values of serum glucose and bilirubin, but significantly (P<0.05) low values of serum BUN and AST. This is indicative of low- level tissue and cellular damage, or probably haemodilution arising from the infusion of lactose in saline.
