| mitochondrial dna analysis of sporothrix schenckii in india, thailand, brazil, colombia, guatemala and mexico. | up to now, 30 mitochondrial dna(mtdna)and 4 rdna types of sporothrix schenckii strains have been identified. here, seventy-six isolates of s. schenckii from mexico, guatemala, brazil, thailand and india were genotyped and studied epidemiologically by mtdna restriction fragment length polymorphisms(rflp)and internal transcribed spacer region(its)-rflp analysis and two new mtdna types, type 31 and type 32, were found. type 30, previously reported by mora-cabrera et al. was confirmed to be type 3 a ... | 2009 | 19194056 |
| [an endemic area of sporotrichosis in guatemala]. | an endemic area of sporotrichosis is described in the lake of ayarza district, south guatemala, where 53 patients have been observed within 3 years. in 45.3% of the cases, the infection appeared after handling fish. the disease was more frequently observed in man (83%) and in patients less than 30 years of age. the most frequent clinical type was the ascending lymphocutaneous sporotrichosis of the limbs. some cases of ulcerative or verrucous lesions were seen. almost all the patients cured rapid ... | 1978 | 360441 |
| [ecological and epidemiological relationships between sporothrix schenckii, a fungus pathogenic for man and the ceratocystis genus]. | sporothrix schenckii is a pathogenic fungus for man and animal. its perfect form is not yet known. many studies have been made to compare this fungus to ascomycetes belonging to the genus ceratocystis. this paper summarizes some important data about the ecology and the epidemiology of the fungal complex sporothrix-ceratocystis. previous results obtained by several groups of workers are strongly in favor of a relationship between the two genera. the epidemiological studies carried out in differen ... | 1978 | 743769 |
| sporothrix globosa, a pathogenic fungus with widespread geographical distribution. | sporothrix globosa, reported from the usa, europe, and asia, is a recently described pathogenic species morphologically similar to sporothrix schenckii. in this study, the phylogenetic affinities of 32 clinical and environmental isolates morphologically identified as s. schenckii, from mexico, guatemala, and colombia, were assessed by cladistic analysis of partial sequences of the calmodulin gene using the maximum parsimony and neighbor-joining methods. the study revealed that one out of 25 isol ... | 2009 | 19635441 |
| phenotyping and genotyping of sporothrix schenckii isolates according to geographic origin and clinical form of sporotrichosis. | sporothrix schenckii isolates of fixed and lymphocutaneous clinical forms from mexico (mx), guatemala (gt), and colombia (co) as well as environmental isolates from mx were studied by analyzing their phenotypic characteristics (conidial length, thermotolerance by percent growth inhibition [gi] at 35 and 37 degrees c, median lethal dose [ld(50)]) and genotypic characteristics (by random amplified polymorphic dna [rapd] analysis-pcr). a significant difference (p < 0.01) in the mean conidial length ... | 2002 | 12149366 |
