Possibility of in-hospital infection by Cryptococcus neoformans in patients with AIDS

ABSTRACT

The objective of the present work was to carry out a survey of soil samples taken from different areas of a hospital of infectious disease located in the city of Córdoba, where three AIDS patients were hospitalized during different periods in the same ward. The three of them returned with meningeal cryptococcosis between three or five months after having been discharged. Cryptococcus neoformans was isolated in 8/10 samples collected outside the hospital, near the pigeon house. The samples collected from the AIDS patients ward and its surroundings were negative. These findings suggest that the patients may have been infected by the fungus during their first stay in hospital
