Enzymatic variability among Brazilian Pythium insidiosum isolates.
BACKGROUND Pythium insidiosum is an oomycete classified in the kingdom Stramenopila. P. insidiosum hyphae are not able to initiate infection without the secretion of hydrolytic enzymes, which are considered an important factor in microbial virulence. AIMS To evaluate the extracellular enzymatic activity of 14 Brazilian P. insidiosum isolates and a standard strain (ATCC 58637) by the API-ZYM S...
متن کاملA molecular phylogeny of Pythium insidiosum.
Sequence analysis of the ribosomal DNA internal transcribed spacers (ITS) was used to establish phylogenetic relationships among 23 isolates of Pythium insidiosum, the etiological agent of pythiosis in mammals. The isolates were divided into three distinct clades that exhibited significant geographic isolation. Clade I consisted of isolates from North, Central, and South America, while clade II...
متن کاملPythium insidiosum: an overview.
Pythium insidiosum is an oomycete pathogenic in mammals. The infection occurs mainly in tropical and subtropical areas, particularly in horses, dogs and humans. Infection is acquired through small wounds via contact with water that contains motile zoospores or other propagules (zoospores or hyphae). The disease, though described as emerging has in fact already been described since 1884. Dependi...
متن کاملMorphological and Molecular Identification of four Brazilian Commercial Isolates of Pleurotus spp. and Cultivation on Corncob
The species of Pleurotus have great commercial importance and adaptability for growth and fructification within a wide variety of agro-industrial lignocellulosic wastes. In this study, two substrates prepared from ground corncobs supplemented with rice bran and charcoal were tested for mycelium growth kinetics in test tubes and for the cultivation of four Pleurotus commercial isolates in polypr...
متن کاملIdentification of Mucorales isolates from soil using morphological and molecular methods
Background and Purpose: Soil is the main habitat of saprophytic and pathogenic fungi. Mucormycetes are one of the most parts of soil fungi and certain members are among opportunistic fungi and can cause systemic fungal infections in immunocompromised patients. The majority of human and animal infections are caused by members of the genera Rhizopus, Mucor, Rhizomucor, Lichtheimia (Absidia), Cunn...
