title: A rare case of feline congenital Toxoplasma gondii infection: fatal outcome of systemic toxoplasmosis for the mother and its kitten.
abstract: This report describes a case of fatal systemic toxoplasmosis in a 2.5-year-old mixed breed pregnant cat and its kittens. The pregnant cat was presented to the gynecology clinic with symptoms of dystocia. The ultrasound examination revealed the presence of five fetuses in the uterus, three of which were not alive, and consequently a cesarean section was performed. However, the mother cat and the remaining two live kittens died two and ten days after cesarean section, respectively. Pathologically, severe alveolar edema, tachyzoite-like structures in the alveolar macrophages and multifocal necroses in the lungs of mother cat were observed. An intense Toxoplasma gondii immunopositive reaction was observed in the cytoplasms of alveolar macrophages, bronchial and bronchiolar epithelia, necrotic foci in the lungs, and Kupffer cells of the liver. PCR analyses amplified T. gondii DNA in tissue samples of the mother cat and kittens. The present study provides strong evidence for a transplacental transmission of T. gondii infection with deadly outcome for the mother cat, fetuses and kittens. As to the authors' knowledge, this report is the first case of fatal congenital toxoplasmosis in domestic cats in Turkey.
