Six goats were experimentally infected with a stock of Trypanosoma viv
ax. Parasitaemia was weekly monitored by buffy coat and wet blood film
examination during a period of 15 weeks and another 3 weeks following
drug-treatment. Dried blood samples were tested by the polymerase cha
in reaction (PCR), using an extraction method with Chelex(R) 100 (BioR
ad). PCR proved consistently more sensitive than the parasitological t
echniques. (C) 1997 Elsevier Science B.V.
