ABSTRACT The antifungal activity of BMS-207147 (also known as ER-30346) was compared to those of itraconazole and fluconazole against 250 strains of fungi representing 44 fungal species. MICs were determined by using the National Committee for Clinical Laboratory Standards (NCCLS)-recommended broth macrodilution method for yeasts, which was modified for filamentous fungi. BMS-207147 was about two- to fourfold more potent than itraconazole and about 40-fold more active than fluconazole against yeasts. With the NCCLS-recommended resistant MIC breakpoints of ≥1 μg/ml for itraconazole and of ≥64 μg/ml for fluconazole against Candida spp., itraconazole and fluconazole were inactive against strains of Candida kruseiand Candida tropicalis. In contrast, all but 9 (allC. tropicalis) of the 116 Candida strains tested had BMS-207147 MICs of <1 μg/ml. The three triazoles were active against about half of the Candida glabrata strains and against all of the Cryptococcus neoformans strains tested. The three triazoles were fungistatic to most yeast species, except for BMS-207147 and itraconazole, which were fungicidal to cryptococci. BMS-207147 and itraconazole were inhibitory to most aspergilli, and against half of the isolates, the activity was cidal. BMS-207147 and itraconazole were active, though not cidal, against most hyaline Hyphomycetes (with the exception ofFusarium spp. and Pseudallescheria boydii), dermatophytes, and the dematiaceous fungi and inactive againstSporothrix schenckii and zygomycetes. Fluconazole, on the other hand, was inactive against most filamentous fungi with the exception of dermatophytes other than Microsporum gypseum. Thus, the spectrum and potency of BMS-207147 indicate that it should be a candidate for clinical development.

Although keratinophilic fungi on avian feathers have been widely described, data from European literature are quite lacking regarding Mediterranean countries. The aim of the present study was therefore to evaluate the occurrence of fungal species on feathers of different avian species in Italy. A total of 378 feather samples from both aquatic (n = 254) and terrestrial birds (n = 124), for a total of 30 bird species, were cultured for keratinophilic fungi. Fungal isolates were recognized by their macro- and micro-scopical morphology, and results were corroborated by PCR and sequencing. Keratinophilic fungi belonging to 11 different species (Scopulariopsis brevicaulis, Chrysosporium keratinophilum, Trichophyton terrestre, Microsporum gypseum, Sepedonium sp., Chrysosporium pannorum, Myriodontium sp., Chrysosporium tropicum, Chrysosporium pruinosum, Chrysosporium luteum and Aphanoascus fulvescens) were isolated from 71 animals (18.8%). The frequency of isolation of keratinophilic species from terrestrial birds was significantly higher in waterfowl. Migratory birds in Italy have been proven to carry pathogenic fungi such as dermatophytes, (A. platyrhyncos, A. crecca, E. rubecula), besides saprophytic species.

In Vitro Interactions

The results of in vitro interactions between colonies of Blastomyces dermatitidis and six other zoopathogenic fungi are reported. The interactions were found to range from neutral with Histoplasma capsulatum and Candida albicans to strongly antagonistic with Microsporum gypseum, Pseudallescheria boydii, and Sporothrix schenckii, and including lysis by Cryptococcus neoformans. These observations suggest that interactions between zoopathogenic fungi may be one of the biotic factors likely to influence the occurrence of B. dermatitidis in natural systems.

Introduction: Information on the prevalence of keratinophilic fungi in West Indies is scanty. Occurrence of keratinophilic fungi in soils of St. Kitts and Nevis has not been investigated previously. Methodology: The prevalence of keratinophilic fungi was investigated in 108 samples of soils of varying habitats from St. Kitts and 55 such samples from Nevis by hair-baiting technique. Fungal growths appearing on the hair baits after four to eight weeks of incubation at room temperature were microscopically examined and cultured on mycological media. Cultures were identified on the basis of colonial and microscopic features. Results: Forty-nine (45%) of the samples from St. Kitts and 38 (69%) from Nevis were positive for keratinophilic fungi. Microsporum gypseum complex, a well-known geophilic dermatophyte, was the most frequently recovered species being present in 15.7%  of soils of St. Kitts and 40% of soils of Nevis. The next commonest species recovered was Chrysosporium indicum, represented by 15 (13.9%) isolates from St. Kitts and seven (12.7%) isolates from Nevis. Other infrequently isolated keratinophilic species included Chrysosporium tropicum, Chrysosporium keratinophilum, and unidentified Chrysosporium species. Conclusions: This study is the first of its kind in the islands of St. Kitts and Nevis. A high incidence of M. gypseum complex in the soil of these islands is a noteworthy finding of public health significance.

Chemically Modified Tetracycline

ABSTRACT Several chemically modified tetracycline analogs (CMTs), which were chemically modified to eliminate their antibacterial efficacy, were unexpectedly found to have antifungal properties. Of 10 CMTs screened in vitro, all exhibited antifungal activities, although their efficacies varied. Among these compounds, CMT-315, -3, and -308 were found to be the most potent as antifungal agents. The MICs of CMT-3 against 47 strains of fungi in vitro were determined by using amphotericin B (AMB) and doxycycline as positive and negative controls, respectively. The MICs of CMT-3 were generally found to be between 0.25 and 8.00 μg/ml, a range that approximates the blood levels of this drug when administrated orally to humans. Of all the yeast species tested to date, Candida albicans showed the greatest sensitivity to CMT-3. The filamentous species most susceptible to CMT-3 were found to be Epidermophyton floccosum, Microsporum gypseum, Pseudallescheria boydii, a Penicillium sp., Scedosporium apiospermum, a Tricothecium sp., and Trichophyton rubrum. Growth inhibition of C. albicans by CMT-3, determined by a turbidity assay, indicated a 50% inhibitory concentration of 1 μg/ml. Thirty-nine strains, including 20 yeasts and 19 molds, were used to measure viability (the ability to grow after treatment with a drug) inhibition by CMT-3 and AMB. CMT-3 exhibited fungicidal activity against most of these fungi, especially the filamentous fungi. Eighty-four percent (16 of 19) of the filamentous fungi tested showed more than 90% inhibition of viability by CMT-3. In contrast, AMB showed fungicidal activity against all yeasts tested. However, most of the filamentous fungi (16 of 19) showed less than 50% inhibition of viability by AMB, indicating that AMB is fungistatic against most of these filamentous fungi. To begin to identify the sites in fungal cells affected by CMT-3, C. albicans and a Penicillium sp. were incubated with the compound at 35°C, and then the fluorescence of CMT-3 was observed by confocal laser scanning electron microscopy. CMT-3 appeared to have widespread intracellular distribution throughout C. albicans and the Penicillium sp. The mechanisms of the antifungal activity of CMT-3 are now being explored.

Introducción: La utilización de recursos de telesalud en sistemas penitenciarios ya posee una larga tradición. Objetivo: Este estudio pretende presentar los resultados asistenciales de pacientes con diabetes e hipertensión, acompañados a través de telesalud en la unidad carcelaria varonil en Querétaro, México. Metodología: Se analizaron 120 pacientes del centro penitenciario varonil de Querétaro, México. Estos pacientes fueron acompañados por telesalud en el período de 4 años (2014-2017), siendo diagnosticados. A partir partir de sus diagnósticos, fueron agrupados en cuatro grandes grupos: diabetes / hipertensión -dislipidemia; hipertensión / dislipidemia, diabetes como única patología e hipertensión como única patología. A partir de estos grupos, se presentan parámetros clínicos de los pacientes-controlados o no. Resultados: Hay un predominio de pacientes con parámetros clínicos controlados en todos los grupos analizados, variando de 71,4% a 61,9% de los pacientes, dependiendo del grupo. Se observa que el grupo que tiene co-morbilidad presenta un mayor de pacientes controlados. Conclusión: La telemedicina se convierte en una herramienta que integra el abordaje clínico, garantiza la continuidad de la atención y puede contribuir para el respeto a los derechos humanos de las personas privadas de la libertad.
