In mice infected with an avirulent strain of Toxoplasma gondii, circulating Toxoplasma antigens were detectable in the sera during weeks 1 to 3 of infection by a simple agglutination test that uses latex particles coated with anti-Toxoplasma antibodies. An infection in athymic nude mice resulted in high agglutination titers in the anti-Toxoplasma antibody-coated latex particle test and the abse...
Brucella canis is the causative agent of canine brucellosis and facultative intracellular pathogen. The diagnosis of canine brucellosis is based on bacteriological examination and serological methods including agglutination and gel diffusion tests. In this study, crude antigens were extracted from B. canis using hot saline, coated on to latex beads and their usefulness in the serological diagno...
The latex agglutination test for Cryptococcus neoformans antigen is a simple and rapid procedure for the diagnosis of cryptococcal meningitis. Although the test is sensitive, care must be taken to prevent contamination of the sample, which may result in false-positive reactions. It was discovered in our laboratory that immersion of a platinum wire inoculating loop into a sample of cerebrospinal...
Vaginal swabs from women who on clinical evidence were thought to have vaginal candidosis were examined for yeasts by conventional laboratory methods (microscopy and culture) and also assayed for Candida antigens using a rapid (3 min) slide latex particle agglutination tests. Results showed that a diagnosis of vaginal candidosis based on clinical criteria alone is unreliable: only half of the w...
In the fields of infectious diseases, a variety of immunoassay methods has been reported. More simple, rapid and cost-effective manual tests for infectious diseases are needed. For the purpose of simple diagnosis of rotavirus infection, a rapid test against human rotavirus was developed. As for the preparation of the reagent, clinically isolated human rotavirus was cultured using MA-104 cells. ...
The dairy industry suffers massive economic losses due to staphylococcal mastitis in cattle. The Staphaureux latex agglutination test (Oxoid, Basel, Switzerland) was reported to lead to negative results in 54% of bovine Staphylococcus aureus strains, and latex-negative strains are thought to be less virulent than Staphaurex latex-positive strains. However, comparative information on virulence a...
Previously, we reported the specific occurrence of neutralizing autoantibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF) in the bronchoalveolar lavage fluid from 11 Japanese patients with idiopathic pulmonary alveolar proteinosis (I-PAP). The autoantibody was also detected in sera from all 5 I-PAP patients examined. To determine that the existence of the autoantibody is ...
