Mice infected by Candida albicans and treated with monoclonal antibody C7 survived longer than saline-treated animals. A prozone-like effect was observed. The in vitro candidacidal activity of macrophages was strongly enhanced when C. albicans was opsonized by C7 and complete murine serum was present.

By using an indirect fluorescent antibody (IFA) procedure, we were recently able to demonstrate that a significant portion of natural antibody reactivity to Gram-negative bacteria resided in the IgG class as well as in the IgM class of antibodies (1). The magnitude of this IgG act ivi ty had apparently eluded detection in previous studies that used bactericidal, agglutination and other tests (2...

The combination of sports sciences theorization and social networks analysis (SNA) has offered useful new insights for addressing team behavior. However, SNA typically represents the dynamics of team behavior during a match in dyadic interactions and in a single cumulative snapshot. This study aims to overcome these limitations by using hypernetworks to describe illustrative cases of team behav...

Computer models were used to examine whether and under what conditions the multimeric protein complex is inhibited by high concentrations of one of its components-an effect analogous to the prozone phenomenon in precipitin tests. A series of idealized simple "ball-and-stick" structures representing small oligomeric complexes of protein molecules formed by reversible binding reactions were analy...

The Coombs test (Coombs, Mourant, and Race, 1945a, 1945b, 1946) has become popular as a sensitive and reliable method of detecting incomplete antibodies. The essential reagent is the serum of an animal (usually a rabbit) which has been immunized with human globulin. Potent rabbit sera sometimes show a prozone phenomenon (Wootton, 1950; Van Loghem, Kresner, Coombs, and Fulton Roberts, 1950). The...

A 40 year patient presented with pyrexia of one month duration. Routine work up for fever of unknown origin (FUO) was negative. Bone marrow aspiration and culture done yielded Brucella. Bone marrow cultures are recommended for patients for FUO for whom the routine workup turns out to be negative. Serological tests for brucellosis can be false-negative in some cases of brucellosis due to prozone...

BACKGROUND Measurement of C-reactive protein (CRP) is used for diagnosing and monitoring systemic inflammatory disease in canine patients. An automated human immunoturbidimetric assay has been validated for measuring canine CRP, but cross-reactivity with canine CRP is unpredictable. OBJECTIVE The purpose of the study was to validate a new automated canine-specific immunoturbidimetric CRP meth...
