Influenza serology has traditionally relied on techniques such as hemagglutination inhibition, microneutralization, and ELISA. These assays are complex, challenging to implement in a format allowing detection of several types of antibody-analyte interactions at once (multiplex), and troublesome to implement in the field. As an alternative, we have developed a hemagglutinin microarray on the Arr...
Here we analyzed whole-genome sequences of 3,969 influenza A(H1N1)pdm09 and 4,774 A(H3N2) strains that circulated during 2009-2015 in the world. The analysis revealed changes at 481 and 533 amino acid sites in proteins of influenza A(H1N1)pdm09 and A(H3N2) strains, respectively. Many of these changes were introduced as a result of random drift. However, there were 61 and 68 changes that were pr...
ABSTRACT: The effect of protein deficiency on the immune response upon primary and secondary stimulation with 5×108 sheep red blood cells (SRBC) was studied in 4 groups of mice fed by diets containing 4 or 21 percent of protein.Primary and secondary immune response were assessed by quantification of direct and indirect plaque forming cells (PFC) in immune spleens and by titration of serum hema...
The polarity of the surface distribution of viral glycoproteins during virus infection has been studied in the Madin-Darby canine kidney epithelial cell line on nitrocellulose filters. Using a surface radioimmunoassay on Madin-Darby canine kidney strain I cells that had been infected with vesicular stomatitis virus or with avian influenza fowl plague virus, we found that the surface G protein w...
