ABSTRACT
Eight female Peromyscus californicus were infected with 10(2) or 10(4) Toxoplasma gondii culture-derived tachyzoites (Type II or X) isolated from southern sea otters. All but 2 mice survived infection and developed antibodies to T. gondii. The 2 fatally infected mice were inoculated with 10(4) tachyzoites of the Type X strain. Parasite detection by immunohistochemistry (IHC) and DNA amplification with 2 polymerase chain reaction (PCR) methods was compared for brain, heart, lung, liver, spleen, biceps muscle, and tongue, at a mean of 41 days postinfection. Parasites were detected most commonly by IHC in spleen (8/8) and brain (6/8). DNA amplification by PCR was most successful from brain, heart, and spleen.
