The salt-free water washings of a sensitized motile bacterium (B. aertrycke) were found to cause a floccular agglutination in the presence of both whole and deflagellated antigen. Evidence was presented that the water washings when salt-free contained flagella and flagellar agglutinin and that clumping occurred upon the addition of saline. The floccular reaction in the presence of deflagellated...

The existence of beta-lectins on protoplast surfaces is confirmed by the agglutination of protoplasts by those Yariv antigens that have sugar specificities which also interact with isolated beta-lectins. Agglutination by beta-maltosyl but not by beta-D-mannosyl Yariv antigens is used to identify some of the structural features required of the ligand for beta-lectin binding. Inhibition of agglut...

adsorbable on an antigen-antibody complex. Its action is inhibited by anticomplementary substances, such as sodium citrate, EDTA, heparin. 2. The quantitative study shows that the intensity of the leuco-agglutination depends on the amount of complement which is present in the reaction: the excess of complement (more than 2/a of normal) inhibits the leuco-agglutination; the optimum is equal to *...

A new latex agglutination test for rubella virus was used to test sera with a hemagglutination inhibition titer of -8 (97 specimens) or >256 (158 specimens). Maximum latex agglutination test sensitivity was achieved when low-titer sera were tested undiluted and high-titer sera were diluted (1:10). A modification of the protocol of the manufacturer resulted in a latex agglutination-hemagglutinat...

Labial agglutination occurs when the labia minora have become fused in the midline through either filmy or dense adhesions, forming a raphe. This condition is typically seen in pre-pubertal girls; however, there have been cases reported in the literature of labial agglutination in postmenopausal and reproductive aged women. Labial agglutination has been associated with local irritation and infl...
