According to Nelson (1953), " the immune-adherence phenomenon" is concerned with the specific attachment which occurs between erythrocytes and micro-organisms which are sensitized by antibody (Ab) and Complement (C'). Measurements of immune-adherence (IA) may be performed by counting the Treponema pallida remaining in the fluid phase of reaction mixtures containing T. pallida, Ab, C', and eryth...

A study was performed to establish the value of immune adherence haemagglutination tests for antibody to hepatitis A virus in the diagnosis of non-B hepatitis. Infection with hepatitis A virus was confirmed in 14 out of 16 patients from six families and seven out of nine patients in whom the source of infection was unknown. One additional patient, who had had two episodes of jaundice, was shown...

Objective: The immunomodulatory effect of geranial, geranial acetate, gingerol, and eugenol essential oils were evaluated by studying humoral and cell-mediated immune responses. Materials and Method: The essential oils were evaluated for immunomodulatory activity in in vivo studies, using rats as the animal model. The essential oils were tested for hypersensitivity and hemagglutination reaction...

Thirty-four antinuclear antibody (ANA) positive systemic lupus erythematosus (SLE) sera were tested for antibodies to double-stranded DNA (dsDNA) simultaneously using Farr, haemagglutination, Crithidia luciliae (CL) kinetoplast fluorescence and human metaphase chromosome fluorescence assays. Significant correlation (p less than 0 x 05) was found between the Farr and CL assays, with the two fluo...

In 1975 and 1976, 7580 serum specimens were tested for HBsAg by the passive haemagglutination test, Hepanosticon. Serum from 38 people gave a positive result after absorption with the absorbent provided, but the presence of HBsAg could not be confirmed by other tests. Tests for current infection with EB virus, namely, the presence of heterophil antibody and EB virus specific IgM, were performed...

A drop in egg production associated with loss of pigment and soft-shelled eggs was experienced on a farm in the Western Cape. Investigations revealed high levels of antibodies against adenovirus 127, the causative agent of egg drop syndrome (EDS) in chickens which were not vaccinated against EDS. A cytopathic agent was subsequently isolated in chicken embryo liver cell cultures and identified a...

Immune and non-immune rubella sera were examined in the haemagglutination inhibition (HAI) test to evaluate the removal of lipoprotein non-specific inhibitors (NSI) of haemagglutination after kaolin and manganous chloride/heparin treatments. The sera were titrated fresh or after lipoprotein deterioration brought about by ageing the samples at 4 degrees C for various periods of time and by freez...
