| The aim of the present experiment was to standardize a nested polymerase chain reaction (nPCR) for the detection of Toxoplasma gondii in tissues of experimentally infected pigs and to compare the performance of nPCR with the standard isolation technique, the bioassay in mice. Comparison between the two methods was done testing eight 4 month-old pigs orally inoculated with 5 x 10(4) oocysts of Toxoplasma gondii (AS-28 strain) and three non-infected pigs at the same age, kept as control. All animals were euthanatized 47 days after infection and samples of brain, heart, tongue and retina were collected from each animal for analysis by nPCR and bioassay in mice. By using the bioassay, Toxoplasma gondii was detected in 4 infected pigs, being two in the retina,... |
