TIV vaccination modulates host responses to influenza virus infection that correlate with protection against bacterial superinfection [PDF]
Background: Influenza virus infection predisposes to secondary bacterial pneumonia. Currently licensed influenza vaccines aim at the induction of neutralizing antibodies and are less effective if the induction of neutralizing antibodies is low and/or the

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.

Cross-protective potential of a novel monoclonal antibody directed against antigenic site B of the hemagglutinin of influenza A viruses. [PDF]
The hemagglutinin (HA) of influenza A viruses has been classified into sixteen distinct subtypes (H1-H16) to date. The HA subtypes of influenza A viruses are principally defined as serotypes determined by neutralization or hemagglutination inhibition ...

Biological activities of aqueous and organic extracts from tropical marine sponges [PDF]
We report on screening tests of 66 extracts obtained from 35 marine sponge species from the Caribbean Sea (Curaçao) and from eight species from the Great Barrier Reef (Lizard Island). Extracts were prepared in aqueous and organic solvents and were tested

Cross-protection between antigenically distinct H1N1 swine influenza viruses from Europe and North America [PDF]
Background An avian-like H1N1 swine influenza virus (SIV) is enzootic in swine populations of Western Europe. The virus is antigenically distinct from H1N1 SIVs in North America that have a classical swine virus-lineage H1 hemagglutinin, as does the ...

Hemagglutination-Inhibition Test in Rhinovirus Infections of Volunteers [PDF]
The hemagglutination-inhibition (HI) test for antirhinovirus antibody was carried out on paired sera from volunteers inoculated with rhinovirus type 3 or type 4 (RV4). The HI test gave results which paralleled the neutralization test and was at least as sensitive as a microneutralization method for detection of serotype-specific antibody. Although high

Evaluation of a rubella hemagglutination inhibition test system [PDF]
Two systems for measurement of rubella hemagglutination inhibition antibodies were compared. One had chick erythrocytes as indicator and the other, which is available in kit form ("Rubindex," Ortho-Diagnostics), uses human group O erythrocytes. Correlation to within one dilution of each other was noted in 92% of the tests.

Epidemiological and virological characteristics of pandemic influenza A (H1N1) 2009 in school outbreaks in China [PDF]
Background: During the 2009 pandemic influenza H1N1 (2009) virus (pH1N1) outbreak, school students were at an increased risk of infection by the pH1N1 virus. However, the estimation of the attack rate showed significant variability. Methods: Two school
