The genetic relatedness of clinical and environmental Cryptococcus neoformans strains in the Maltese Islands was investigated by randomly amplified polymorphic DNA fingerprinting with four primers. The clinical strains isolate over the course of 1 year from AIDS patients showed identical fingerprints. The electrophoretic patterns of the two clinical strains(More)
Ninety-seven environmental and four clinical isolates of Cryptococcus neoformans from several localities in extreme southern Italy were serotyped. All proved to be Cr. neoformans var. neoformans serotype A. The homogeneity of the serotypes suggests that geographical climatological conditions may play a role in Cr. neoformans serotype diffusion. It was(More)
Yeast isolates that share the same habitats as Cryptococcus neoformans var. neoformans serotype A in a restricted Mediterranean area were assayed in order to verify their killer activity against Cr. neoformans strains isolated from clinical and environmental sources. Many of the environmental yeast isolates expressed the killer phenomenon against the(More)
To understand the epidemiological significance of Pneumocystis detection in a lung tissue sample of non-immunosuppressed individuals, we examined sampling procedures, laboratory methodology, and patient characteristics of autopsy series reported in the literature. Number of tissue specimens, DNA-extraction procedures, age and underlying diagnosis highly(More)
