The results observed with this strain of Treponema pallidum may be stated as follows: 1. Normal human serum did not agglutinate this culture of Treponema pallidum in dilutions of 1:5 or higher; equal parts of treponema culture and normal serum (dilution 1:2) resulted in agglutination in about 50 per cent of the sera. With the strain of Treponema pallidum used in this study specific agglutinatio...

Enzyme linked and agglutination direct antiglobulin tests were carried out on blood samples from 219 patients suspected of having autoimmune haemolysis. The enzyme linked tests were more sensitive: they could detect the small amounts of IgG, IgA, and IgM which are normally present on red cells and showed increased amounts of cell bound immunoglobulins in patients with Coombs test negative autoi...

Agglutination of yeast, human group A and guinea pig erythrocytes by multiple clinical isolates of E. coli, K. pneumoniae, and P. aeruginosa was investigated and correlated with hydrophobicity measurements of each bacterial strain. Hydrophobicity of the isolates, as measured by hydrophobic interaction chromatography, was similarly correlated with in vitro adherence of the microorganisms to bucc...

The autologous red cell agglutination assay reagent consists of an antibody or antibody fragment of a human erythrocyte-specific monoclonal antibody (mAb) conjugated to an antigen of interest. This bi-functional reagent causes the agglutination of the patient's erythrocytes in the presence of the antigen-specific antibodies in the patient's serum. Previously, such reagents have been produced ei...

Background: Leishmaniasis is an infection caused by a protozoan of the genus Leishmania. This descriptive and cross-sectional study was done in order to determine the seroepidemiology of visceral leishmaniasis in East Myankooh area, in Lorestan Province during 2004 – 2005 time period. Materials and methods: This study was a descriptive, cross-sectional study. Multi stage sampling was performed...
