Na tentativa de identificar a possível fonte de infecção, inquiriu-se, na história epidemiológica de 42 pacientes portadores de criptococose, o contato com pombos. Informações compatíveis com nicho ecológico do Cryptococcus neoformans foram positivas em 16. Foram colhidas 59 amostras de solo contendo fezes de pombos, penas e material orgânico. O C. neoformans foi detectado em 4. Uma das amostras era originada da capital e três do interior do estado. O sorotipo A do C. neoformans isolado de um liquor coincidiu com o sorotipo da amostra isolada do centro de Porto Alegre, local apontado pelo paciente como possível fonte de infecção, caracterizando caso de Cryptococcus neoformans var. neoformans.
