Trypanosoma cruzi infection in sylvatic mammals of the quebracho woods of the eastern part of Santiago del Estero province, Argentina, was studied from October 1984 to December 1987. 301 mammals of 20 different species were caught. T. cruzi, characterized biologically and biochemically, was isolated by xenodiagnosis from 23 of 72 (32%) Didelphis albiventris(More)
Cultivation of specialty mushrooms on lignocellulosic wastes represents one of the most economical organic recycling processes. Compared with other cultivated mushrooms, very little is known about the nature of the lignocellulolytic enzymes produced by the edible and medicinal fungus Grifola frondosa, the parameters affecting their production, and enzyme(More)
We report the first systematic epidemiological research carried out in Argentina on the skunk Conepatus chinga. Forty-nine animals were captured in the settlements of Amamá, Trinidad, and nearby forested areas located in the Department of Moreno, Province of Santiago del Estero, between April 1985 and May 1989. Isolation of parasites was done through(More)
To identify wild hosts of Trypanosoma cruzi, surveys were conducted in the subandean valleys of Jujuy Province, Argentina, between June 1986 and March 1987. Seventy two mammals from 13 different species were examined by xenodiagnosis. Fifty two of them were mostly rodents trapped at the localities of Maimará, León and Tilcara, and the remainder had been(More)
We present the case of an adolescent with mucor rhinosinusitis diagnosed concomitantly with acute lymphoblastic leukemia at a hospital in Tegucigalpa, Honduras. We also discuss the challenges faced in the dual management of hematologic malignancies and invasive fungal disease in a low-middle-income country, such as access to diagnostics, immunosuppressants,(More)
Strains of Agaricus brasiliensis require special procedures for conservation. Thus, the objective of this research was to establish conservation and maintenance procedures A. brasiliensis strain PSWC838 from the University of Pennsylvania (ABWC838) and an A. brasiliensis strain from the Fujian Agriculture and Forestry University (ABC). The medium in which(More)
The composting is an aerobic, microorganism-mediated, solid-state fermentation process by which different organic materials are transformed into more stable compounds. The product obtained is the compost, which contributes to the improvement of physical, chemical and microbiological properties of the soil. However, the compost usage in agriculture is(More)
Polysaccharides produced by microorganisms represent an industrially unexploited market. An important number of polysaccharides have been isolated from fungi, especially mushrooms, with many interesting biological functions, such as antitumor, hypoglycemic, and immunostimulating activities. In the search of new sources of fungal polysaccharides, the main(More)
