Previous studies have shown contrasting results concerning the variability of the pulsed-field gel electrophoresis (PFGE) subtypes of C. albicans observed in HIV-positive patients. Carriage of C. albicans was determined by an oral rinse technique; 41 strains of C. albicans (78% serotype A and 22% serotype B) were isolated. There was a direct correlation between candidal load (cfu/ml) and the blood HIV load, whereas there was an inverse correlation with the stage of disease and the CD4 cell counts. The PFGE patterns of isolates were variable with regard to the number and positions of bands. The variability of the band sizes in some run positions showed a Gaussian distribution. Generally, the most frequent size variants were associated with the strains with the highest cfu/ml and lowest CD4 counts (< or =200 cells/microl)....

The Italian and Antarctic strains had different growth rates and membrane fatty acids at different temperatures.

The most frequently isolated dermatophyte was in 2821 positive cases Microsporum canis (50%), followed by Trichophyton rubrum (27%), Trichophyton mentagrophytes (10.6%), Epidermophyton floccosum (9.3%), Microsporum gypseum (2.3%), Trichophyton violaceum (0.6%), Trichophyton tonsurans (0.2%) and Trichophyton verrucosum (< 0.1%). The genera and species isolated were also considered in relation to the site of the lesion. Our epidemiological data were compared with those obtained by other authors in other cities and with those obtained in Rome in previous studies conducted between 1972-77 and 1978-83. Results obtained by various investigators in Europe are also discussed.

Nine soil samples collected from as many sites along the coast of Ross Sea, and six dust samples inside the Italian scientific base were examined by direct inoculation and hair baiting methods for soil samples and plate dilution method for dust samples. As regards the variety of species isolated and the counting of the numbers of colonies, plate dilution method proved to be very effective. Aspergillus spp., Cladosporium sp., Dematiaceae, Fusarium sp., Geomyces pannorum v. pannorum, G. pannorum v. vinaceus, Mycelia sterilia, Penicillium spp. were isolated from soil. From the dust the following moulds were isolated: Aphanoascus fulvescens, Aspergillus sp., Beauveria sp., Chrysosporium carmichaelii, Dematiaceae, Geomyces pannorum v. pannorum, G. pannorum v. vinaceus, Malbranchea gypsea, Mycelia sterilia, Nectria inventa, Penicillium spp., Scopulariops& brevicaulis, Scopulariops& sp. and Trichophyton mentagrophytes. The presence of four colonies of Trichophyton mentagrophytes is emphasized and correlated with the anthropization process.

METHODS: 11 patients reporting bronchial work-related symptoms, in 9 associated with nasal symptoms, underwent: SIC with the suspected agents (7 low and 4 high molecular weight), induced sputum before and 24h after the SIC and nasal secretion examination before and 30 min, 4h and 24h after SIC. Nasal secretion was processed with dithothreitol as sputum to obtain an homogeneous cell suspension. RESULTS: 4/11 patients had a positive bronchial SIC and 4/11 a positive nasal SIC. Only one patient had both a nasal and bronchial positive response. After SIC an increase in sputum eosinophils (> than 5% or > than 2.0x10 5 eosinophils/ml) was found in 8/11 patients and an increase in nasal eosinophils (>than 15%) in 6/11. On the basis of SIC alone 4 patients were diagnosed as OA, 4 as OR and 1 as OA and OR. Four SICpatients with increased sputum eosinophils after SIC could be diagnosed as occupational eosinophilic bronchitis. Two patients with nasal SIC-had increased nasal eosinophils after SIC. CONCLUSIONS: Our data suggest that the evaluation of airway and nasal inflammation after SIC improves the ability of SIC in confirming nasal and/or bronchial work-related symptoms.
