Resumo: Foi feita uma investigação sobre a ocorrência de P. carinii em 361 roedores, incluindo ratos de esgoto, ratos albinos, camundongos albinos, cobaios e coelhos. Só foram encontrados positivos 4 Rattus norvegicus em 215 examinados (1.8%). Estes resultados estão de acordo com observações feitas nos últimos anos, os quais constrastam com as verificações feitas nos primeiros anos, os quais contrastam com as verificações feitas nos primeiros anos de estudo do P. carinii, quando foram assinalados altos índices infecciosos. Entretanto, em 20 ratos albinos tratados com corticosteróides (betametasona) foram encontrados 8 positivos (40%); e em 20 camundongos albinos, tratados do mesmo modo, foram encontrados 9 positivos (45%). Estes resultados confirmaram o caráter oportunístico do P. carinii no roedores, do mesmo modo como acontece no homem.

P. carinii was found in 4 of the 215 Rattus norvegicus examined (1,8%). These results accord with recent observations but disagree with investigations made by the researchers who first studied this parasite in the past when high indexes of infection were found. However, in 20 albino rats treated with corticosteroids (betamethazone) we found 8 positive (40%) and in 20 albino mice treated by the same way, 9 were positive for P. carinii (45%). These results confirm the opportunistic character of P. carinii in rodents already well demonstrated in man.Fundação Oswaldo Cruz. Instituto Oswaldo Cruz. Laboratório de Protozoologia.
