Résumé

We report the analysis of 4892 parasitological stool samples coming from outpatients and patients of a nutritional recuperation center of north Santiago. Cryptosporidium parvum was detected in 21 samples (0.4 percent). The protozoan was detected in 6 of 1203 samples from children of less than 2 years old, 3 of 1.727 samples from children between 6 and 15 years, none of 776 samples from healthy adults and 2 of 13 samples from HIV infected patients. Nine of 97 children of less than 2 years old, hospitalized in the nutritional recuperation center, were infected with Cryptosporidium; this frequency was significantly higher than that of outpatients of the same age. Most infections were detected from May to August, a rainy and midly cold period. It is concluded that Cryptosporidium infections are infrequent in healthy outpatients and that its prevalence increased in hospitalized children and HIV infected adults

Résumé

The earth of ornamental plants is one of the main reservoirs of Aspergillus type of fungi in hospital areas. We studied 174 ornamental interior plants from a hospital at Santiago. Samples were obtained from the soil surface and sowed in Sabouraud-glucose agar, adding streptomycin and G-penicillin. After 72 h of culture, at least one strain of Aspergillus was isolated from 140 samples (80.5 percent). The most frequently isolated strain was A fumigatus (129 samples), followed by A miger (75 samples). A fumigatus and A niger were the only isolated strains in 65 and 11 samples respectively. These findings confirm that ornamental plants can be important reservoirs of Aspergillus strains, a potential infectious agent for immunocompromised patients in hospital areas
