In the early spring of 2013, Chinese health authorities reported several cases of H7N9 influenza virus infections in humans. Since then the virus has established itself at the human-animal interface in Eastern China and continues to cause several hundred infections annually. In order to characterize the antibody response to the H7N9 virus we generated several mouse monoclonal antibodies against...

John, T. Jacob (University of Colorado School of Medicine, Denver), Marlene Stahl, and Vincent A. Fulginiti. Cumulative hemagglutination by Mycoplasma pneumoniae and other agglutinins. J. Bacteriol. 92:1002-1004. 1966.-The phenomenon of cumulative hemagglutination, or hemagglutination by two agglutinins, each in subagglutinating concentration, was demonstrated by use of four different systems, ...

Hemagglutination of erythrocytes is a common property of Staphylococcus epidermidis strains, which is related to adherence and biofilm formation and may be essential for the pathogenesis of biomaterial-associated infections caused by S. epidermidis. In three independent biofilm-producing, hemagglutination-positive S. epidermidis isolates, interruption of the icaADBC operon essential for polysac...

to prepare hemagglutination inhibition (hi) antigen the egg drop syndrome virus (edsv) was propagated in 10-day-old embryonated duck eggs. the virus antigen was inactivated with two methods including heating (65°c) and adding 0.5% formaldehyde by considering low destroying effect on hemagglutination (ha) and hi titers. the edsv hi titers of 310 sera and 100 yolks obtained from 23 chicken farms ...

An indirect hemagglutination test for the detection of antibodies in swine serum specific for pseudorabies virus is described. The indirect hemagglutination test was less time consuming than the standardized virus nertralization test while being highly sensitive and accurate. Serum samples that were toxic to virus neutralization indicator cells were readily tested in the indirect hemagglutinati...

hemagglutination activity (enhanced lectin activity) not expressed by nonactivated platelets, and this agglutinin mediates the direct platelet-platelet interactions that cause the aggregation of thrombinactivated platelets. The enhanced agglutinin activity of thrombin-activated platelets is composed of two components: a plasma membrane-bound component and a soluble component.3 The expression of...

Clematis montana lectin (CML), a novel mannose-binding lectin purified from C. montana Buch.-Ham stem (Ranunculaceae), has been proved to have hemagglutinating activity in rabbit erythrocytes and apoptosis-inducing activity in tumor cells. However, the biochemical properties of CML have not revealed and its structural information still needs to be elucidated. In this study, it was found that CM...

The study examined the phytochemical composition, DPPH radical scavenging activity, hydrogen peroxide scavenging radical activity, ferric reducing power, hemolytic inhibition, hemagglutination inhibition and antibacterial activity of methanol leaf extract of Ficus sycomorus and P. thonningii plant. The results showed the presence of tannins, saponnins, flavonoids, glycoside and phenols while te...
