Composition, serologic reactivity, and immunolocalization of a 120-kilodalton tube precipitin antigen of Coccidioides immitis

Autor: Garry T. Cole, D Kruse, R W Wheat, K R Seshan, S W Zhu

Publikováno v: Infection and Immunity. 58:179-188

Diagnosis of coccidioidomycosis largely depends on serologic tests. In this investigation, the enzyme-linked immunosorbent assay (ELISA) was used to detect patient immunoglobulin M (IgM) precipitin antibody binding to a 120-kilodalton (kDa) fraction

Autor: M, Ohkawa, S, Tokunaga, M, Takashima, T, Nishikawa, H, Hisazumi, S, Fujita, R W, Wheat

Publikováno v: Chemotherapy. 36(6)

A total of 231 isolates of Candida species including 163 of Candida albicans (132 of serotype A and 31 of serotype B), 42 of Candida tropicalis, 17 of Candida glabrata, 7 of Candida parapsilosis and 2 of Candida krusei were collected from clinical sp

Reactivity to spherule-derived coccidioidin in the southeastern United States

Autor: R W Wheat, C E Buckley, H A Gallis, J R Cohn, W W Woodruff

Publikováno v: Infection and Immunity. 43:860-869

Delayed hypersensitivity skin tests with mycelium-derived (coccidioidin) or spherule-derived (spherulin) antigens (or both) can be used to identify patients who have been sensitized to the dimorphic fungus Coccidioides immitis. Prior studies suggest

Degradation of 14C-labeled streptococcal cell walls by egg white lysozyme and lysosomal enzymes

Autor: Sara E. Miller, R W Wheat, Harry A. Gallis

Publikováno v: Infection and Immunity. 13:1459-1466

The resistance of native and trypsin-treated [14C] glucose-labeled cell walls to degradation by lysozyme and human lysosomal enzymes was confirmed. In contrast, chemically N-acetylated cell walls undergo significant degradation by these enzymes in th

Enhancement of macrophage-mediated tumor cell killing by bacterial outer membrane proteins (porins)

Autor: R W Wheat, J B Weinberg, E Ribi

Publikováno v: Infection and Immunity. 42:219-223

Various microbial products are known to influence the function of mouse peritoneal macrophages. Lipopolysaccharide (LPS) and certain lipid A-associated proteins are known to enhance the tumoricidal effects of macrophages. The purpose of this study wa

Occurrence of antigenic (species-specific?) partially 3-O-methylated heteromannans in cell wall and soluble cellular (nonwall) components of Coccidioides immitis mycelia

Autor: R W Wheat, R S Haltiwanger, W W Woodruff

Skin test-active, phenol-soluble, water-soluble (PSWS) extracts of Coccidioides immitis whole, defatted mycelia were compared with skin test-active, alkali-soluble, water-soluble (ASWS) extracts of mycelial cell walls. Both PSWS and ASWS extracts con

Serological cross-reactivity between group B Streptococcus and Sporothrix schenckii, Ceratocystis species, and Graphium species

Autor: Y Nakamura, H Ishizaki, R W Wheat

Serological cross-reactivity of a group B Streptococcus (H36B) with Sporothrix schenckii and 39 different Ceratocystis and Graphium species was investigated by double immunodiffusion. Rabbit anti-H36B serum reacted with antigens from S. schenckii and

Extraction of skin test activity from Coccidioides immitis mycelia by water, perchloric acid, and aqueous phenol extraction

Autor: R W Wheat, E R Scheer, K S Su Chung, E P Ornellas

Water, perchloric acid extracts, and fractions of partially defatted whole mycelia of Coccidioides immitis contained delayed skin test activity when tested in C. immitis-infected guinea pits. Aqueous phenol extraction of these fractions resulted in p

Strain variation in composition and molecular size of the capsular polysaccharide of Cryptococcus neoformans serotype A

Autor: J M Small, Thomas G. Mitchell, R W Wheat

The capsule of Cryptococcus neoformans is an important virulence factor. In this investigation capsular polysaccharides (CPSs) were isolated by ethanol precipitation from culture filtrates of C. neoformans serotype A strains 6, 15, 98, 110, and 145.
