[In vitro activity of amphotericin B, itraconazole and voriconazole against 20 species of Aspergillus using the Sensititre microdilution method].

Background: The in vitro activity of antifungal agents against Aspergillus has been recently investigated. We studied the susceptibility to amphotericin B, itraconazole and voriconazole of 68 strains belonging to 20 different Aspergillus species.

Methods: The minimum inhibitory concentrations (MICs) for 10 strains of A.

[Carbohydrate assimilation by clinical and environmental Rhodotorula glutinis strains].

This study was carried to determine the carbohydrate assimilation patterns of Rhodotorula strains isolated from clinical and environmental specimens. We have tested the commercial system ID 32C (bioMerieux, France) on 80 different strains of Rhodotorula glutinis: 47 strains from clinical samples and 33 strains from environmental samples. The assimilation percentages obtained in our study for galactose, cellobiose, gluconate and sorbose were lower than those showed in the identification table of the method.

[Candida ciferrii in an immunocompromised patient].

A case of possible infection due to Candida ciferrii in an immunocompromised patient is presented. This fungal species has been rarely reported as cause of human infection. The isolate showed in vitro resistance to fluconazole.

[Characteristics of tuberculosis in patients older than 65 years in the sanitary area of Cadiz (Spain)].

Background: Tuberculosis in the elderly is an increasing public health problem.

Aim: To describe the epidemiological, clinical and microbiological characteristics of tuberculosis in patients over 65 years old, as compared to younger patients.

Material And Methods: We reviewed the case histories of tuberculosis, microbiologically diagnosed by Ziehl-Neelsen/auramine smear and Löwenstein-Jensen culture, in patients over 65 years old, in the sanitary area of Cadiz (Spain).
