Cryptococcal infection has been increasing among immunosuppressed population. We report three cases of Cryptococcus neoformans infection in immunosuppressed patients - two renal transplanted and one with lupus nephritis. Early infection (<3months) was diagnosed in two - an allograft Cryptococcus infection and a central nervous system involvement. The third, a 10-year transplant vintage patient,...
Cryptococcus neoformans is a yeast-like organism associated with pulmonary, meningoencephalitic, or systemic disease. This case report documents 2 cases of cryptococcosis with central nervous system involvement in captive cheetah (Acinonyx jubatus). In both cases the predominant post mortal lesions were pulmonary cryptococcomas and extensive meningoencephalomyelitis. Both cheetahs tested negati...
Cryptococcosis is an acute, sub-acute or chronic fungal disease caused by an encapsulated basidiomycetous yeast belonging to the genus Cryptococcus (Jagdish Chander). It is among the most prevalent lifethreatening mycoses and has a worldwide distribution (Meyer et al., 2003). Among the many species of the genus “Cryptococcus” that are prevalent ubiquitously in environment, C. neoformans and C. ...
Cryptococcosis is a potentially fatal fungal disease commonly identified in patients with acquired immunodeficiency syndrome. Cryptococcus infection induces strong pro-inflammatory cytokine secretion, i.e. type-I interferon (IFN-I) via the Toll-like receptor signaling pathway. However, innate immune responses are insufficient in host defense against fungi infection and the clearance of Cryptoco...
Cryptococcosis is one of the most common opportunistic fungal infections in patients with acquired immunodeficiency syndrome (AIDS). We report 13 cases of cryptococcal infection based on histopathology, serology and cultures. Epidemiological analysis, histochemical techniques of hematoxilin and eosin (HE) and Grocot's silver (GMS), as well special histochemical techniques such as Mayer's mucica...
Cryptococcosis is a potentially lethal disease of humans/animals caused by Cryptococcus neoformans and Cryptococcus gattii. Distinction between the two species is based on phenotypic and genotypic characteristics. Recently, it was proposed that C. neoformans be divided into two species and C. gattii into five species based on a phylogenetic analysis of 115 isolates. While this proposal adds to ...
Invasive fungal infections, particularly those considered opportunistic, have become a common and significant complication of procedures performed in advanced contemporary medicine. Among such infections, cryptococcosis, which is usually caused by infection with Cryptococcus neoformans and Cryptococcus gattii, is particularly problematic because this fungal infection occurs in immunocompromised...
Among 80 types of yeast isolated from wild flowers in Daejeon, Korea, two species that have not yet been identified by phylogenetic analysis of the internal transcribed spacer-2 (ITS2) genes and 26S rDNA sequences were identified as Candida sp. 44-C-1 and Cryptococcus sp. 9-D-1. Neither of the newly identified species formed ascospores, while Candida sp. 44-C-1 formed pseudomycelium and Cryptoc...
Compared to the incidence in adults, cryptococcosis is rare among children. We report a case of neurocryptococcosis due to Cryptococcus gattii in a five-year-old girl without identified risk factors living in French Guiana. Neurological surgery in combination with long-term antifungal treatment with amphotericin B and 5-flucytosine successfully resolved the cryptococcal infection. Subsequent mo...
