Bacteriol. 92:82-87. 1966.-The complement-fixation fluorescent-antibody test provided a means of differentiating between antibodies of Cryptococcus neoformans and Candida albicans. The test was applied to the sera of 134 pigeon fanciers f...
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 کاملImmune Modulation Mediated by Cryptococcal Laccase Promotes Pulmonary Growth and Brain Dissemination of Virulent Cryptococcus neoformans in Mice
C. neoformans is a leading cause of fatal mycosis linked to CNS dissemination. Laccase, encoded by the LAC1 gene, is an important virulence factor implicated in brain dissemination yet little is known about the mechanism(s) accounting for this observation. Here, we investigated whether the presence or absence of laccase altered the local immune response in the lungs by comparing infections with...
متن کاملDifferential regulation of immune responses by highly and weakly virulent Cryptococcus neoformans isolates.
Early inflammatory responses, delayed-type hypersensitivity (DTH) responses, and cytokine profiles were studied in mice infected by the pulmonary route with either a highly virulent isolate (NU-2) or a weakly virulent isolate (184A) of Cryptococcus neoformans. After infection, NU-2 remained in the lungs and the capsule became more pronounced during the first 24 h, whereas 184A induced an immedi...
متن کاملAspects of antigen mimicry revealed by immunization with a peptide mimetic of Cryptococcus neoformans polysaccharide.
We have recently identified peptide mimetics of the Cryptococcus neoformans capsular polysaccharide by screening phage display peptide libraries. 2H1, one of a large family of mAbs against the glucuronoxylomannan fraction (GXM), is highly protective and binds several peptide motifs. This study analyzes the immunologic properties of P601E (SYSWMYE), a peptide from the low affinity motif (W/YXWM/...
