Passive hemagglutination test for measles immunity and serodiagnosis.

A passive hemagglutination (PHA) test for measles was evaluated in comparison with hemagglutination inhibition (HI) and neutralization (NT) tests. The PHA test determines exclusively the level of antibody directed to the hemagglutinin protein of measles virus. The ratio of PHA to HI titer was 1 to 32 (geometric mean, 6.5) for the first 5 weeks of infection but declined to near unity thereafter....

Passive hemagglutination test for bovine chlamydial abortion.

Purified chlamydial elementary bodies were subjected to sonic lysis to produce soluble antigen for passive hemagglutination (PHA). PHA was more sensitive than complement fixation (CF) in detecting antibody in hyperimmunized rabbits, lambs, and calves. Both CF and PHA tests were used to monitor antibody responses in experimentally infected pregnant cows. All animals responded with rises in titer...

Hemagglutination test for rapid serodiagnosis of human pythiosis.

Human pythiosis is an emerging, life-threatening infectious disease, caused by the oomycete Pythium insidiosum. Thailand is an area where human pythiosis is endemic and the genetic blood disorder thalassemia is a predisposing factor. Patients with pythiosis present with arterial occlusions of the lower extremities, corneal ulcers, or chronic cutaneous infections. Diagnosis relies on time-consum...

Specificity of the passive hemagglutination test for antibody to rubella virus and the passive hemagglutination response after vaccination.

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.
