Serotyping of Cryptococcus neoformans by dot enzyme assay.
A method is described for the serotyping of Cryptococcus neoformans based on direct analysis of culture supernatants for the major type-specific capsular antigen, glucuronoxylomannan. Factor sera prepared by absorption of polyclonal rabbit antisera (Iatron Laboratories, Inc., Tokyo, Japan) or selected anti-C. neoformans monoclonal antibodies were used in a dot enzyme assay to detect the presenc...
متن کاملDETECTION OF CRYPTOCOCCUS NEOFORMANS BY SEMINESTED PCR IN CEREBROSPINAL FLUID
ABSTRACT Life-threatening infections caused by the encapsulated fungal pathogen Cryptococcus neoformans have been increasing steadily over the past 10 years. Cryptococcus neoformans is recognized as the most frequent fungal infection of the central nervous system (CNS) in immunocompetent as well as immunocompromised patients. We report the development of a semi-nested- PCR-based assay for the ...
متن کاملCryptococcus neoformans.
Seven nonencapsulated mutants of Cryptococcus neoformans were isolated from an encapsulated strain of human origin. Initially, the mutants were avirulent for mice. After several months of subculturing, six of the seven isolates reverted LO the encapsulated state and possessed varying degrees of virulence. The results of these experiments suggest that a strong correlation exists between the pres...

متن کاملSerotyping of Cryptococcus neoformans isolates from clinical and environmental sources in Spain.
We determined biovars and serotypes of 154 isolates of Cryptococcus neoformans from clinical and environmental sources from different areas of Spain. All clinical isolates belonged to C. neoformans var. neoformans. Serotypes showed an irregular distribution. C. neoformans var. gattii serotype B was isolated from necropsy specimens from goats with pulmonary disease.
