An Hemagglutination Test for Titration of Antibodies to Polioviruses.
SummaryAn hemagglutination technic for the titration of antibodies to polioviruses has been described. The HA titers showed approximately a 75% correlation with neutralizing antibody. The virus-sensitized cells did not remain agglutinable for more than 2 days at 5°C, but have proven stable for at least 6 weeks when kept frozen. An antigenic cross among

ABSTRACT Coagulant Moringa oleifera lectin (cMoL) is one of the compounds involved in the application of M. oleifera seeds for traditional water treatment methods. The present study highlights the new biotechnological potential of cMoL lectin as an antifungal agent against Cryptococcus neoformans B3501 and H99 and Cryptococcus gattii R265 strains ...

Preliminary Report on a Hemagglutination Test for Entamoebae.
SummaryAntigens prepared from E. invadens and E. histolytica, DKB strain grown in monomicrobial culture with T. cruzi in Phillips' medium have demonstrated high sensitivity and been used successfully in reciprocal hemagglutination tests with specific antisera prepared in rabbits. The antigen prepared from E.

Analysis of the Diluents Used for Rubella Virus Hemagglutination and Hemagglutination-Inhibition Tests [PDF]
A new diluent (ADGP) for the rubella virus hemagglutination (HA) and hemagglutination-inhibition (HI) tests is described. It was found that the HA and HI titers and the erythrocyte agglutination pattern were improved in ADGP compared to previously described diluents.

Predictive Value of Laboratory Assays Toward Autoimmune Diseases
With an increasing number of unmet medical needs for autoimmune diseases (AD) in the United States, it is important to assess the value of laboratory assays in diagnosis. Healthcare providers must understand general and specific laboratory results that can lead to an efficient diagnosis.

Application of a ddRT-PCR to quantify seasonal influenza virus for viral isolation
Viral isolation in cell cultures has been regarded for decades as the “gold standard” for the laboratory diagnosis of influenza viral infections. Not all viral strains could be isolated from clinical samples.

Stable mycoplasma antigen preparations for indirect hemagglutination tests.
In immunological studies of mycoplasmas, the use of glutaraldehyde for the fixative makes it possible to use erythrocytes from commercially available defibrinated sheep blood. It eliminates the necessity of having to screen blood from individual sheep to
