Dermatomycoses caused by Nattrassia mangiferae in São Paulo, Brazil – 2004

03
out
Nattrassia mangiferae formerly known as Hendersonula toruloidea, is a phaeoid coelomycete described by Nattrass in 1933.We report five cases of N. mangiferae infections in São Paulo, Brazil. This fungus was isolated from interdigital lesions on the feet in one patient, toenails in three cases and fingernails in the other one. The infections were initially considered to be caused by a dermatophyte....



Contamination of peritoneal dialysis fluid by filamentous fungi – 1999

03
out
Peritonitis is a frequent complication in peritoneal dialysis. It may be caused by contamination of the dialysis tubing or by extension of the catheter exit site. Gram-positive bacteria are the most common organism, accounting for 60% of all documented cases of continuous ambulatorial peritonitis dialysis. Fungi are isolated from to 1- 15% of cases. Forty-nine out of 490 bottles containing fluid for peritoneal...

O gênero Fusarium compreende uma grande quantidade de espécies que comumente são fitopatógenas e saprófitas do solo, sendo a minoria patogênica para o homem.



Corneal Ulcer Caused by the New Fungal Species – 2002

03
out
We describe a case of keratitis caused by a new species of the hyphomycetous genus Sarcopodium, S. oculorum. The corneal ulcer developed after 5 months of treatment with corticosteroids in a Brazilian boy diagnosed with allergic conjunctivitis. Fungal hyphae and conidia were detected in corneal scrapings, and repeated cultures were positive for this fungus. The infection was resolved with natamycin...

03
out
Las infecciones fúngicas han aumentado en el último tiempo, entre ellas las causadas por hongos levaduriformes. Siendo descritas actualmente como levaduras emergentes, han sido confundidas frecuentemente con especies del género Candida, presentando diferencias sutiles en las características morfofisiológicas, además de presentar patrones de susceptibilidad diferentes al género Candida. El presente...

30
set
To determine the incidence of Tinea capitis in São Paulo, Brazil, an investigation was performed in Private and Public Pediatrics Service involving 4,500 children from 0 to 15 years old during 5 years (1996–2000).Samples were taken from 132 children with suspected fungal infection of the scalp, for direct microscopy and culture. Tinea of scalp was mycologically confirmed in 112 patients (85%).Males...



Heterogeneity of proteins expressed by Brazilian Sporothrix schenckii isolates – 2009

30
set
The profiles of proteins present in the exoantigens of Brazilian Sporothrix schenckii isolates were studied and compared by electrophoresis (SDS-PAGE). Thirteen isolates from five different regions of Brazil (1,000 to 2,000 km apart) and ten from a more limited region (200 to 400 km apart within the state of São Paulo) were cultured in Sabouraud, M199 and minimum (MM) media. Qualitative and quantitative...



PERFORMANCE OF THE ALBICANS ID2® CHROMOGENIC MEDIUM FOR RAPID – 2006

30
set
The aim of our study was to evaluate the accuracy of the chromogenic media Albicans ID2® (bioMérieux, France) for the identification of Candida albicans among 330 yeast strains. All C. albicans (100) and C. dubliniensis (20) strains exhibited blue color when cultured on Albicans ID2®. However, the blue color was also exhibited by cultures of C. rugosa (30/30) and C. tropicali (3/50) isolates.



Onychomycosis caused by Fusarium solani and Fusarium oxysporum in São Paulo Brazil – 2004

30
set
Fusarium species are common soil saprophytes and plant pathogens that have been frequently reported as etiologic agents of opportunistic infections in humans. We report eight cases of onychomycosis caused by Fusarium solani (4) and Fusarium oxysporum (4) in São Paulo, Brazil. These species were isolated from toenails in all cases. The infections were initially considered to be caused by dermatophytes....



Species Distribution and Antifungal Susceptibility Profile of Candida spp. Bloodstream Isolates from Latin American Hospitals – 2003

30
set
From March 1999 to March 2000, we conducted a prospective multicenter study of candidemia involving five tertiary care hospitals from four countries in Latin America. Yeast isolates were identified by classical methods and the antifungal susceptibility profile was determined according to the National Committee for Clinical Laboratory Standards microbroth assay method. During a 12 month-period we were...
