Le nouvel essai de Pascal Picq s’inscrit dans ces ouvrages marquants science et societe. Si le titre inspire des airs comedies, c’est surtout sous-titre, qui n’est pas annonce en couverture, “Coercition violence sexuelles chez l’Homme” reflete contenu. Sa parution fait echo a d’autres publications generalistes (e.g. Martin, 2013) particulier “L’Homme prehistorique est aussi une femme” M. Patou-...

Avian influenza viruses replicate in a variety of mammals and birds, yet hemagglutination inhibition tests show that postinfection sera from these animals (e.g., ferrets and ducks) have insignificant levels of antibodies (Hinshaw et al., Infect. Immun. 34:354-361, 1981). This suggested that avian influenza viruses, in contrast to mammalian viruses, may not induce a significant humoral response....

Enzyme-linked immunosorbent assay and hemagglutination methods were compared using mycobacterial glycolipids as antigens. Both methods were found to have equivalent specificity and sensitivity in detecting mycobacterial diseases. Both tests had 96% specificity; the sensitivity of the enzyme-linked immunosorbent assay was 86%, and that of the hemagglutination test was 88.6%.

An indirect hemagglutination test has been adapted for use with varicella-zoster serology. Antigen was made in infected WI-38 human diploid cell line. The indirect hemagglutination antigen seemed to be a subunit of the virus particle. The antibodies measured in the test are well correlated with neutralizing and complement-fixing antibodies in cases of zoster but not in cases of varicella.

Three serological procedures, the agar-gel precipitin inhibition, the complement fixation, and the indirect hemagglutination tests, were used to detect and measure antibody to Yersinia pestis in the sera from 383 individuals. Although all three tests were useful in detecting plague antibody, the most reliable and sensitive test procedure was indirect hemagglutination.

Goose erythrocytes preserved with glutaraldehyde were compared with fresh cells in hemagglutination and hemagglutination-inhibition tests for arbovirus antigens and antibodies. The glutaraldehyde-fixed cells were as sensitive and specific as theresh erythrocytes and were stable at 4 degrees C for 6 months.

Five erythrocyte species (horse, goose, chicken, guinea pig, and human) were used to agglutinate avian influenza H5N1 viruses by hemagglutination assay and to detect specific antibody by hemagglutination inhibition test. We found that goose erythrocytes confer a greater advantage over other erythrocyte species in both assays.

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. The influence of the components of ADGP and of various test conditions on optimal HA and HI results were examined.

Background: Decay of vaccine–induced antibody titres without boosting of the wild measles virus has been well documented. Revaccination against measles has reduced the prevalence of the disease worldwide. Revaccination may cause IgE induced anaphylaxis. Objective: To study measles IgG antibody in revaccinated populations and its relation to IgE induced hypersensitivity. Methods: Blood samples w...
