Studies on Influenza Virus
Influenza complement fixation tests designed for use with ferret serum are described. Complement-fixing antigens derived from influenza ferret lungs were unsatisfactory due to their low content of soluble antigen; those prepared from mouse lungs or developing chick embryo membranes proved to be better antigenically and were reliable when the various reagents in the test were properly adjusted t...
متن کاملAn analysis of seroepidemiological studies of herpesvirus type 2 and carcinoma of the cervix.
There are 2 aspects of the Seroepidemiological studies of herpesvirus type 2 and cervical cancer that impose lim itations upon the interpretation of the data. One aspect is the antibody assay systems; the degree of accuracy with which the present assay systems detect past infections with herpesvirus type 2 is not known (27). The 2nd problem is the difficulty in controlling for the attributes of...

متن کاملStudies on Epidemic Influenza Virus
Evidence is presented which indicates that influenza virus elaborates a soluble antigen. The antigen is considerably smaller than the virus and can be separated from it, but the virus has not been washed free of antigen. The properties of the antigen suggest that it is an unstable protein of relatively large size.
متن کاملSeroepidemiological and ecological studies of the adenovirus-associated satellite viruses.
The seroepidemiology of the defective adenovirus-associated satellite viruses was studied by use of a neutralization test that has been shown to be much more sensitive than the complement-fixation (CF) test. Less than 25% of the subjects in any age group were positive for any type of satellite virus CF antibody. The neutralization test revealed serological evidence of satellite infection in alm...
