Agglutinins in Relation to Blood Transfusion
The reason for the compatibility or otherwise between two bloods was discovered by Landsteiner in I900. He found by a series of cross-testings with red corpuscles and blood sera from different individuals that all bloods could be divided into four chief groups according to the presence or absence from the corpuscles of one or other or both of two agglutinogens A and B. Two corresponding aggluti...
متن کاملPseudothrombocytopenia Caused by Platelet Agglutinins That Are Reactive in Blood
The phenomenon of in vitro platelet clumping and consequent pseudothrombocytopenia in the presence of EDTA was studied in the plasmas and sera of three patients. A heterogeneity was identified among these platelet agglutinins. lgG agglutinins present in two patients recognized antigens that were present when EDTA was added to platelets. This effect of EDTA did not appear to be mediated by calci...
متن کاملInvestigation for background prevalence of Brucella agglutinins among blood donors.
(w ww .m ed kn ow .co m) . The results are shown in the Table. The exponential character of turbidity increase was less sensitive yet a more speciÞ c screening criterion, thus it is suitable for preliminary conÞ rmation of signiÞ cant bacteriuria. The non-speciÞ ed turbidity increase estimation2 has a high negative predictive value and is suitable (just like the biochemical screening)1,3 for pr...
متن کاملFlagellar Agglutinins
1. Certain bacilli within one strain may lose their flagella and become non-motile. 2. The change in serological behavior associated with the change in motility indicates that the flagella possess an individual antigenic property. 3. Flagella can be separated from the bodies of the bacilli. 4. A strictly flagellar antiserum can be produced by the injection of a flagellar suspension. 5. This dir...

Although considerable evidence has accumulated that rheumatic fever is a streptococcal infection, attempts to demonstrate specific streptococcal agglutinins in the serums of patients with tWis disease have met with only a moderate degree of success. Tunnicliff (1) performed agglutination reactions with the serums of twelve rheumatic fever patients against strains of Micrococcus rheumaticus and ...
