An avian H5N1 influenza A virus (A/Hong Kong/156/97) was isolated from a tracheal aspirate obtained from a 3-year-old child in Hong Kong with a fatal illness consistent with influenza. Serologic analysis indicated the presence of an H5 hemagglutinin. All eight RNA segments were derived from an avian influenza A virus. The hemagglutinin contained multiple basic amino acids adjacent to the cleava...
A Mycoplasma-associated immunosuppression of the primary and secondary hemagglutinin response to a common gram-negative antigen of Escherichia coli (014) was demonstrated in the rabbit when preincubated mixtures of common gram-negative antigen and Mycoplasma arthritidis membranes were injected intravenously. A similar immunosuppression was demonstrated only for the secondary hemagglutinin respo...
Infection of mice with Histoplasma capsulatum depressed their ability to form agglutinins against foreign erythrocytes. Animals previously inoculated with 10(8) yeast cells of H. capsulatum showed the most significant depression, occurring when erythrocytes were injected 8 days after infection. The average log(2) hemagglutinin titer was 2.7 compared to 8.0 for the control (noninfected) group. I...
The H1N1 influenza virus is a serious threat to human population. Oseltamivir and Zanamivir are known antiviral drugs for swine flu with observed side effects. These drugs are viral neuraminidase and hemagglutinin inhibitor prevents early virus multiplication by blocking sialic acid cleavage on host cells. Therefore, it is of interest to identify naturally occurring novel compounds to control v...
