T. gondii was isolated from 159 samples of diaphragm and 98 samples of swine brain. Of 159 groups of 2 mice each inoculated with diaphragm suspensions, 8 reacted to the methylene blue dye test or to the indirect fluorescent antibody test, titers ranging from 1:16 to 1:1024 for the single forms of parasite isolated. Of the groups inoculated with swine brain suspensions, 7 showed titers ranging from 1:16 to 1:256, for the 4 forms of T. gondii isolates. The samples isolated were pathogenic to mice. Sarcocystis sp. was detected in 30% of the diaphragms analyzed.
