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 کاملSpecificity of Cryptococcus neoformans factor sera determined by enzyme-linked immunosorbent assay and dot enzyme assay.
An indirect enzyme-linked immunosorbent assay (ELISA) and a dot enzyme assay (DEA) were used to determine the specificities of Cryptococcus neoformans factor sera to serotype type-specific capsular polysaccharides, glucuronoxylomannans (GXMs). Pure and chemically characterized GXMs were obtained from representative isolates of C. neoformans serotypes A, B, C, and D. Distinctive specificity patt...
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 کاملEnzyme-linked immunosorbent assay for detection and quantification of Cryptococcus neoformans antigen.
An enzyme-linked immunosorbent assay was standardized for the detection of cryptococcal antigen in serum and cerebrospinal fluid. The system was evaluated in clinical samples from patients infected by human immunodeficiency virus with and without previous cryptococcosis diagnosis. The evaluated system is highly sensitive and specific, and when it was compared with latex agglutination there were...
