Survival of paracoccidioides brasiliensis yeast cells under microaerophilic conditions / Ángela Restrepo Moreno ; Beatriz Elena Jiménez ; Catalina de Bedout Gómez
Título : Survival of paracoccidioides brasiliensis yeast cells under microaerophilic conditions Tipo de documento : documento electrónico Autores : Ángela Restrepo Moreno, ; Beatriz Elena Jiménez, ; Catalina de Bedout Gómez, Fecha de publicación : 1981 Títulos uniformes : Journal of Medical and Veterinary Mycology Idioma : Inglés (eng) Resumen : The ability of P. brasiliensis yeast cells to withstand microaerophilic conditions was investigated in a liquid medium distributed in tall columns in screw-capped tubes. Young cells of three isolates were inoculated on top of the medium, and the tubes were incubated aerobically and anaerobically at 36°C for 28 days. The viability of cells that had sedimented to the bottoms of the tubes was studied by fluorescent microscopy and by their capacity to resume growth when transferred to fresh medium under continuous agitation. The proportion of viable cells in the sediments diminished with time of incubation. However, after 28 days, 27% of the cells were still viable and fully capable of active growth when placed under adequate aeration. On the other hand, drastic reduction of oxygen access elicited an accelerated death rate, with no survival after 7 days of incubation.

Título : In vitro susceptibility testing of Paracoccidioides brasiliensis to sulfonamides Tipo de documento : documento electrónico Autores : Ángela Restrepo Moreno, ; María D. Arango, Fecha de publicación : 1980 Títulos uniformes : Antimicrobial Agents and Chemotherapy Idioma : Inglés (eng) Resumen : A total of 60 clinical isolates of Paracoccidioides brasiliensis were tested for susceptibility to sulfadiazine and sulfadimethoxyne by the agar dilution technique. A modification of the Mueller-Hinton medium was devised which gave good growth of the yeast form. The minimum inhibitory concentrations for only 51.6% of the isolates were in the range of the recommended blood serum concentration (50 micrograms/ml). For 6 to 8% of the isolates, the minimum inhibitory concentrations were above 200 micrograms of both sulfadiazine and sulfadimethoxyne per ml. A significant decreases in susceptibility was demonstrated for one isolate obtained from a patient relapsing during sulfonamide therapy.

Título : Ketoconazole in Paracoccidioidomycosis: Efficacy of prolonged oral therapy Tipo de documento : documento electrónico Autores : Ángela Restrepo Moreno, ; Gloria Isabel Mejía de Rodríguez, ; Iván Gómez, Fecha de publicación : 1980 Títulos uniformes : Mycopathologia Idioma : Inglés (eng) Resumen : Ketoconazole, a new oral imidazole derivative, was employed for the treatment of five patients with paracoccidioidomycosis. The response was excellent, with objective clinical improvement and healing of both mucocutaneous and pulmonary lesions. Mycological and serological tests, as well as delayed hypersensitivity, were assessed and found to correlate with clinical improvement. Therapy was conducted for 12 months with a dose of 200 mg day in 2 patients; in the remainder the dose was reduced (100 mg day) after the first 6 months and maintained as such for an equal period. No side-effects or toxicity were noted despite prolonged treatment. The advantages of the new therapeutic approach are discussed. Mención de responsabilidad : A. Restrepo, D. A. Stevens, E.
