human influenza a viruses: rapid plaque assay in hamster kidney cells.the production of focal necrosis in hamster kidney cells maintained beneath an overlay of semisolid agar medium free of serum permits rapid, reproducible, quantitative assay for the three subtypes of influenza a viruses. adaptation of virus to these cells was not required. a straight-line dose-response relationship was observed betweeen the number of plaques produced and the relative concentration of virus. specificity was demonstrated by quantitative neutralization with immune serum.196414150335

further observations on the relevance of serologic recapitulations of human infection with influenza use of a photometric method which objectively distinguishes between homologous and heterologous antibody reactions, the age distribution of specifically reacting swine and asian antibodies present in sera of persons not recently exposed to either virus was established. the findings support the thesis that the unique distribution by age of swine and asian antibodies recognizes two past periods of prevalence of swine and asian-like viruses, respectively. the findings apparently refute the concl ...196414238927

surveys of respiratory virus antibodies in an arctic indian population.a study was undertaken to determine the etiological agents responsible for epidemics in a small and relatively isolated arctic community.three serological surveys were carried out over a four-year period employing complement fixation tests. clinical information from the resident nurse was also available.the results indicated that of the two clinical epidemics of "influenza" which occurred during the period of study one was due to influenza virus type a; the other was unidentified. however, influ ...19654284108

avian influenza a viruses.the antigenic structure of eight strains of influenza a viruses of avian origin was investigated by haemagglutination inhibition, virus neutralization and strain-specific complement fixation. all strains could be distinguished from each other, but certain cross-reactions were observed allowing the establishment of four antigenic groupings, as follows: (1) classic fowl plague virus ("dutch" strain), turkey/england/63 ("langham" strain) and virus n; (2) two strains isolated from ducks, one in czec ...19655294310

histochemical studies of lysosomes and lysosomal enzymes in virus-infected cell cultures.the appearance of lysosomes and the distribution of lysosomal enzymes have been studied in a number of cell cultures exposed to viruses. lysosomes were shown by fluorescence microscopy after vital staining with aminoacridines and light microscopy after vital staining with neutral red. the lysosomal enzymes studied histochemically in unfixed and fixed cells were acid phosphatase and 5-bromo-4-chloro-indoxyl acetate esterase. activation of lysosomal enzymes was found to take place in three stages. ...196514270244
lysosomal enzymes in cells infected with cytopathic and non-cytopathic chick embryo cells infected with fowl plague virus, an avian strain of influenza a which produces cytopathic effects, lysosomal enzymes were released from the particulate to the supernatant fraction of homogenates within 6 hours of infection. this change occurred in the presence of high concentrations of parafluorophenylalanine, suggesting that the changes were due to redistribution of preformed enzymes rather than to de novo protein synthesis. no such changes were observed when the melbourne ...196514270245
zbitnew a: upper respiratory disease in thouroughbred horses: studies of its viral etiology in the toronto area, 1960 to 1963.from outbreaks of upper respiratory infection of horses in the toronto area between 1960 and 1963, several viruses have been isolated. the viruses, isolated in tissue cultures or eggs, include an equine strain of myxovirus parainfluenzae 3; two strains of equine influenza virus, a/equi-1/prague/56, and a/equi-2/miami/63; equine rhinopneumonitis virus, and two newly recognized viruses of the horse, equine rhinoviruses. in addition serological evidence suggested a widespread infection with these v ...196514230908

studies on the content of antibodies for equine influenza viruses in human sera.previous workers had demonstrated that some of the viruses that caused the influenza epizootics of 1956 and 1963 among horses are antigenically related to certain human influenza viruses. the present authors therefore studied the distribution of antibodies for the equine influenza viruses in human sera. they found that three strains of a/equi 2 virus (1963 miami, 1963 richelieu and 1963 milford) are antigenically related and that there is a cross-relationship between the mouse line of the equine ...19665296537
