ABSTRACT
An acute clinical picture of variable intensity may occur during the initial primary phase of HIV infection, it may however pass unnoticed. We report 12 seronegative subjects (11 male homosexuals, 1 female heterosexual, aged 18 to 44 years old), that sembling an acute clinical picture preceding seroconversion. All had a sudden beginning, reduration were variable, lasting a mean of 14 (range 5-44) days an remaining asymptomatic thereafter. Most patients presented a discrete leukopenia with lymphopenia at the expense of CD4 lymphocytes, followed by an absolute lymphocytosis in some, with an increase in CD8 lymphocytes. All became positive for HIV; circulating HIV antigen was identified in 3 and IgM anti-HIV antibodies were detected during the symptomatic period by third generation ELISA in other 3. It is concluded that the clinical picture of primary HIV infection has identificable clinical serological and immunological features and its recognition has diagnostic and preventive implications

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
