Abstract
By using a simple and easily available device which contains a 10% buffered formaldehyde solution, fecal samples are rendered odorless and can be stored at room temperature with no biosafety hazards. Cryptosporidium oocysts contained in such fecal samples can be identified without difficulty by using the Kinyoun method. This system permits an adequate preservation of the material, which facilitates the execution of tasks related to assistance and epidemiology.

Conforme as finalidades consideradas em diferentes situações, estão disponíveis várias modalidades de conservação
Tornou-se imprescindível conceder atenção ao Cryptosporidium parvum, protozoário que infecta pessoas imunocompetentes ou imunodeprimidas e, atualmente, muito em evidência pela freqüente participação no contexto da aids
Summary
By using a simple and available device which contains a 10% buffered formaldehyde solution, fecal samples are rendered odorless and can be stored at room temperature with no biosafety hazards. Influem para que esta providência fique adotada a inexistência em determinado lugar de condições suficientes a fim de permitir satisfatória análise, a realização de inquéritos epidemiológicos com necessidade de envio de matéria fecal para lugar diferente daquele onde foi coletada e a ocorrência de intervalo variável entre a obtenção e a execução dos procedimentos desejados.
