Nonspecific reactions by the passive hemagglutination test for rubella viral antibody occurred with 1.5% of sera tested. Rises in passive hemagglutination titers (greater than or equal to 4X) occurred with some serum samples taken 14 days after vaccination.

Rantz and associates (1952, 1956) discovered an unusual antigen which is present in many species of gram-positive and absent in gramnegative bacteria, and referred to it as "nonspecies specific (NSS) antigen." This antigen becomes readily attached to erythrocytes and thus renders the latter specifically agglutinable by antibodies directed against it. Sheep red blood cells modified by Rantz anti...

one hundred sera from children 1 - 6 years of age, representative of a large serum collection, were tested for the prevalence of antibodies against different viruses. hemagglutination-inhibition (hi) antibodies were found in 68% for measles; 61 % for rubella; 75'% for influenza a2/hong kong/68, 16% for influenza b/md./59, 0% for group a arboviruses, 10% for group b arboviruses, 3% for phlebotom...

Influenza vaccines have long been manufactured in embryonated chicken eggs. This method has some problems such as a production period (about 6 months) and use of large amounts infectious pathogens. Recently, the recombinant subunit using baculovirus–insect cell system extensively investigated. In this system, viral immunodominant components can be produced more rapidly larger scale than convent...

two sialic acid specific lectins episesarma tetragonum agglutinin–1 and 2 were purified from the hemolymph of the mangrove crab, episesarma tetragonum . the major lectin was purified using cnbr-activated sepharose 4b conjugated to fetuin. n-acetyl glucosamine containing buffer was used for elution. the hemagglutination activity of purified lectin was inhibited by glycoproteins containing siaα, ...

The immunomodulatory proteins present in garlic have recently been shown to be identical to the garlic lectins ASA I and ASA II [Clement F, Pramod SN, Venkatesh YP. Int. Immunopharmacol. 2010; 10: 316-324]. In this study, the stability of garlic lectins as a function of pH, temperature and denaturants has been examined in relation to biological activity (hemagglutination and hagocytosis). Stabi...

The adenovirus fiber mediates the agglutination of erythrocytes. Based on differential hemagglutinating properties, subgenus D adenoviruses can be subdivided into clusters DI, DII, and DIII. While subgenus DI adenoviruses agglutinate rat and human erythrocytes, DII adenoviruses simply agglutinate rat erythrocytes and DIII adenoviruses display no or only weak rat erythrocyte agglutination. Amino...

Several strains of Pseudomonas aeruginosa exhibited the ability to hemagglutinate erythrocytes. Hydrophobic bond-breaking agents, but not sugars and saccharides, were effective inhibitors of hemagglutination. The results suggest the involvement of hydrophobic bonds in hemagglutination reactions of P. aeruginosa.

A passive hemagglutination inhibition assay was studied by using a hyperimmune serum from rabbits immunized with whole yeast cells (Candida albicans group A). This technique was effective at detecting small amounts of laboratory-prepared mannan or a whole-cell extract of C. albicans. Of 32 patients with documented disseminated candidiasis that were tested, 19 showed evidence of circulating anti...

A specific hemagglutination reaction has been described (1) between the sera of tuberculous experimental animals or human beings and sheep erythrocytes treated with extracts or products of the culture filtrates of tubercle bacilli. Observations on this reaction have been confirmed and extended by other investigators (2-6). The present paper is concerned with a modification of this test which in...
