Fungal infection in the oral cavity is not uncommon. The site involved is usually species related. Cryptococcus rarely infects the oral cavity. We report an elderly patient who presented with a central lesion on the dorsum of the tongue. Biopsy revealed a fungal infection. Special stains confirmed cryptococcus. Being a rare location for cryptococcal infection, clinical suspicion should be corre...

A sensitive and diagnostically applicable conjugate for the rapid and accurate detection and identification of Cryptococcus neoformans has been developed. C. neoformans rabbit antisera were produced by 14 daily intravenous injections of 36 million cells for a total dosage of approximately 500 million cells. Cross-staining reactions with species of Cryptococcus other than C. neoformans, as well ...

BACKGROUND Meningitis continues to be one of the most important infections diagnosed and treated by emergency physicians. Despite the advent of anti-infective therapy, meningitis carries a mortality rate of 20%-40%. In this study, we describe the first reported emergency medicine case of meningitis associated with Cryptococcus gattii to alert providers of this insidious, emerging global pathoge...

Cryptococcus spp. other than Cryptococcus neoformans are generally considered nonpathogenic to humans. There are only 15 case reports of disease in humans caused by Cryptococcus laurentii infection. Underlying diseases and predisposing risk factors seem to play an important role in these cases. Our patient is the first case of an extremely low birth weight infant with C. laurentii fungemia repo...

The laccase enzyme and melanin synthesis have been implicated as contributors to virulence in Cryptococcus neoformans. Since isolations of Cryptococcus species other than C. neoformans from clinical specimens have been increasing, we examined the laccase activities of C. albidus, C. laurentii, C. curvatus, and C. humicola. Incubation of cells with epinephrine produced adrenochrome color in C. a...

Cryptococcus neoformans, the agent of cryptococcosis, had been considered a homogeneous species until 1949 when the existence of four serotypes was revealed based on the antigenic properties of its polysaccharide capsule. Such heterogeneity of the species, however, remained obscure until the two morphologically distinct teleomorphs of C. neoformans were discovered during the mid 1970s. The tele...
