Hemagglutination Test for Toxoplasmosis

Science, 1957
The importance of adequate serological tests for toxoplasmosis is accentuated by the tremendous gains in knowledge concerning this infection, which stemmed from the description of the in vitro dye test by Sabin and Feldman in 1948. In the less than 8 years since this discovery, the serology of toxoplasmosis has been characterized and forms of the ...

Hemagglutination and Hemagglutination - Inhibition with Killed Mycoplasma Antigen

Avian Diseases, 1965
Hemagglutination (HA) and hemagglutination-inhibition (HI) with Mycoplasma gallisepticum (MG) were first demonstrated by van Herick and Eaton (5). Little use was made of these findings until Jungherr et al. (2) reintroduced the procedure, in 1953. Thereafter, numerous investigators used the HI test for detecting antibodies for M. gcllisepticum.

Hemagglutination and Hemagglutination-Inhibition Studies with Echo Viruses

The Journal of Immunology, 1962
Summary A study of several factors which may affect hemagglutinin (HA) production revealed that a dilute inoculum combined with a relatively late harvest time favored maximum HA titers of ECHO 6 viruses grown in monkey kidney tissue culture.

Serologic Classification of Chimpanzee Adenoviruses by Hemagglutination and Hemagglutination Inhibition

The Journal of Immunology, 1969
Abstract Twenty-two strains of viruses, each possessing adenovirus complement-fixing antigen and each derived from fecal specimens of chimpanzees, have been classified by their hemagglutinating properties into three major subgroups.

Hepatitis A virus hemagglutination and a test for hemagglutination inhibition antibodies

Journal of Clinical Microbiology, 1989
Like enteroviruses, hepatitis A virus (HAV) hemagglutinated various species of erythrocytes under similar conditions. HAV-specific antibodies in both acute- and convalescent-phase sera were found to inhibit hemagglutination. The HAV hemagglutination inhibition test can be used for diagnosis, epidemiological surveillance, and vaccine assessment.

Hemagglutination properties of Enterococcus

Current Microbiology, 1995
In total, 86 enterococcal strains including representatives of most of the described species were tested for the ability to agglutinate human, sheep, and rabbit erythrocytes. Five strains did not react with any of the erythrocytes tested, and 81 (94.2%) strains agglutinated only rabbit erythrocytes. The hemagglutination titers ranged from 2 to 64. Loss

Automatized Hemagglutination Kinetics

Vox Sanguinis, 1978
Abstract. An automatized technique for the study of hemagglutination kinetics is described. It was used to differentiate between homozygous and heterozygous individuals in the Rh system. Other applications are proposed.

A Special Theory of Hemagglutination*

Vox Sanguinis, 1966
SummaryA special theory of hemagglutination is developed to estimate antigen strength and antibody concentration under antigen excess in an automated system, using either hemolysis or counting of free cells. Antigen strength and antibody concentration are both expressed in terms of A, the number of bivalent antibody molecules in a given volume which ...

Hemagglutination Inhibition Assay

2020
The hemagglutination inhibition (HI) assay for influenza A virus has been used since the 1940s. The assay may be utilized to detect or quantify antibodies to influenza A viruses and can be used to characterize differences in antigenic reactivity between influenza isolates.
