2005
ABSTRACT DNA was extracted from 70 pork sausage samples obtained from 55 commercial establishments inthe city of Botucatu, Sao Paulo, Brazil. Nested-polymerase chain reaction with primers specific for Toxoplasma gondii SAG2 locus was used and detected the parasite in 19 (27.14%) sausage samples.Digestion of amplicons with restriction enzymes HhaI and Sau3AI showed that 14 (73.68%) samplescontained parasites genotyped as Type I, and 5 (26.32%) as Type III. Key words: Toxoplasma gondii ; SAG2 genotyping; food-borne pathogen; sausage; swine. * Universidade Paranaense (UNIPAR).
