Comparison of Mycoplasma synoviae Hemagglutinating Antigens by the Hemagglutination-Inhibition Test
Avian Diseases, 1980Mycoplasma synoviae (MS) strains were isolated from the trachea of hens from MS-positive broiler breeder flocks having progeny condemnations due to airsacculitis. Hemagglutinating (HA) antigens were made from several strains. The HA antigen made from the 95th medium passage of MS FMT strain was compared with that of the standard MS WVU 1853 strain by ...

Influence of albumin on rubella virus hemagglutination and the hemagglutination-inhibition test
Canadian Journal of Microbiology, 1975The HEPES–saline–albumin–gelatin (HSAG) diluent found optimal for agglutination of fowl erythrocytes by rubella virus antigen is also optimal for agglutination of trypsin-treated human group O cells. Albumins from different commercial sources, however, can have varying inhibitory effects on rubella hemagglutination titers.

Simple hemagglutination inhibition test for the diagnosis of toxoplasmosis
Journal of Clinical Microbiology, 1985A simple hemagglutination inhibition (HI) test for the serological diagnosis of toxoplasmosis has been developed and evaluated. A total of 84 human and 120 mouse serum samples were tested by the newly developed HI test and compared with an immunoglobulin G-indirect fluorescent antibody test. Statistical analysis of serum titers obtained by using the HI

Sensitive hemagglutination inhibition test for mumps antibody
Journal of Clinical Microbiology, 1981Incorporation of heterologous immunoglobulin against human immunoglobulin G into the mumps HI tests provided a highly sensitive and specific way of measuring mumps antibody in human sera. The sensitivity of this enhanced mumps HI test compared favorably with that of an anti-immunoglobulin-enhanced virus plaque neutralization test, but the HI test ...

A Hemagglutination-Inhibition Test for Mycoplasma meleagridis Antibodies
Avian Diseases, 1969A hemagglutination-inhibition test for demonstrating antibodies to Mycoplasma meleagridis is reported. Antigen used in the test was prepared from a hemagglutinating strain of M. meleagridis isolated from a turkey embryo. The antigen, suspended in phenolized saline, could be stored at 50C for weeks and still be effective. Examination of serums from both

Use of Turkey Erythrocytes for Vaccinia Virus Hemagglutination and Hemagglutination-Inhibition Tests
American Journal of Clinical Pathology, 1974Turkey erythrocytes are uniformly susceptible to agglutination by vaccinia virus hemagglutinin prepared from the chorioallantoic membrane of the chick embryo and from primary rabbit kidney tissue cell cultures. Forty-seven lots of erythrocytes were tested and all were agglutinated by vaccinia virus.

Avian Diseases, 1969
SUMMARY A satisfactory hemagglutinating (HA) antigen was produced from isolate WVU 1853 of M. synoviae grown in a mycoplasma broth formulated by Frey. The HA antigen, employed in the HI test, showed good specificity in differentiating M. synoviae from M. gallisepticum infection.

Hemagglutination-Inhibition Test for the Evaluation of the Antigenicity of Ascarid Fractions
The American Journal of Tropical Medicine and Hygiene, 1969Abstract In order to develop a logical method of purifying antigenically active fractions of Ascaris lumbricoides, we devised a hemagglutination-inhibition technique. This test measures the ability of a particular fraction to inhibit the activity of a standard antiserum in the hemagglutination test. A homogenate of adult A.

Hemagglutination-Inhibition Test for Methamphetamine Excreted in Human Urine
Journal of Forensic Sciences, 1979Abstract Recently radioimmunoassay (RIA) methods have been developed for the determination of nanogram levels of methamphetamine in urine [1–3]. These methods are suitable for rapid screening but require expensive instrumentation.
