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...

Objective: The objective of the study was to seroprevalence TTIs (transfusion transmissible infections) among blood donors from records (June 2017–May 2022) at center, JLN Hospital and associated group Hospital, Ajmer, Rajasthan. Methods: A cross-sectional carried out over a period 5 years June 2017 May 2022. Serum samples were screened for hepatitis B virus (HBV), C (HCV) (III generation ELISA...

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.

Influenza A viruses (IAVs) belonging to the goose/Guangdong (Gs/GD)-lineage H5Nx remain a major concern for global poultry industry, wildlife, and humans. The hemagglutinin (HA) protein is dominant antigenic epitope carrier within IAV, which in turn triggers substantial immunogenic responses infected host. current study describes development validation of highly sensitive competitive H5 ELISA (...

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...

Patients ranged from those with no prior diagnosis of or suspected exposure to Entamoeba histolytica to those with proven amoebic liver abscesses (extraintestinal disease). A comparison of serologies from patients with proven and suspected amoebiasis or possible past exposure revealed good correlation between the indirect fluorescent antibody (IFA) procedure and the other methods used, counteri...

Immune adherence hemagglutination was compared with the complement fixation test as a means of measuring antibodies to varicella-zoster virus. Analysis of acute- and convalescent-phase sera from patients infected with varicella-zoster or with herpes simplex virus showed the immune adherence hemagglutination test to be more sensitive than the complement fixation test, and greater cross-reactivit...

Reverse passive hemagglutination (RPHA) tests and a latex agglutination test with monoclonal antibodies (MAbs) were developed for the rapid detection of noncultivatable human group C rotaviruses. For RPHA tests, two MAbs, MAb 5A12 recognizing the outer capsid and MAb 13A3 recognizing the inner capsid, were separately used for the coating of sheep erythrocytes (SRBCs). Forty-six fecal samples we...
