The increased sensitivity and improved agglutination and settling patterns of formalinized sheep erythrocytes in a new buffer, HEPES (N-2-hydroxyethylpiperazine N'-2'-ethanesulfonic acid), make this system more suitable for use in the rubella hemagglutination-inhibition test.

HBsAg presence has been searched in blood donors by Reverse Passive Hemagglutination(RPH) test the years of 1987-1993 Atatürk Blood Bank Gaziantep. 2902(4.8 %) 59287 were found as HBsAg-Positive. Relation between groups healthy and carriers was evaluated. statistically using X 2 significance difference two percentage tests. positivity rate lower than expected ratio A B groups, value 0 group, hi...

A new method for attaching antigens to latex by an avidin-biotin technique is described. The procedure permits control of the amount of antigen attached to the latex and eliminates the need for highly purified antigens and destructive bridging chemicals. The avidin-biotin latex agglutination assay is a simple, rapid test well suited to detection of viral antibody. The sensitivity and specificit...

The circulation of influenza C viruses in Rio de Janeiro, Brazil, was studied when significant levels of antibodies were detected (56. 7%) with hemagglutination inhibition test, used as a standard methodology for influenza virus studies.

Njeruh, F.M; Gathuma, J.M; Tumboh-Oeri, A.G Date: 1986 A method for preparation of a hydatid cyst antigen antigen "880" of Echinococcus granulosus origin by heat treatment of concentrated cattle hydatid cyst fluid (HCF) is described. The thermo-stable antigen was applied in the serological diagnosis of human hydatidosis where a total of 78 "blind" sera were examined by the indirect hemagglutina...

Eight domestic ferrets (Mustela putorius furo) and two Siberian polecats (M. eversmanni) were inoculated subcutaneously with 12 to 1.2 x 10(7) Yersinia pestis originally isolated during an epizootic of plague in white-tailed prairie dogs (Cynomys leucurus) near Meeteetse, Park County, Wyoming (USA) in 1985. None of the ferrets or polecats developed clinical signs of disease which suggested that...

BACKGROUND Syphilis, a known major public health issue for soldiers during periods of conflict, is exacerbated in the Democratic Republic of Congo due to widespread sexual violence. However, there has been no previous study to determine the extent of this problem. Therefore, we determined the prevalence of syphilis among young demobilized soldiers. METHODS Screening of syphilis using the rapi...

This is a description in some detail of the sensitized sheep cell hemagglutination test for rheumatoid arthritis as it is currently carried out in this Clinic. Sustained interest in the pathogenesis, natural history, and treatment of rheumatoid arthritis leads us to direct a significant portion of the investigative studies toward improvements in the serological method with fairly exact definiti...
