Ribonuclease present in myxoviruses.
Endoribonuclease splitting single-stranded poliovirus RNA is associated with virions of the myxoviruses fowl plague virus and Newcastle disease virus. These virions are devoid of deoxyribo nuclease hydrolyzing single-stranded M 13 phage DNA and ribonuclease hydrolyzing double stranded poliovirus RNA. The latter enzyme, however, is present in allantoic fluids of infected chick embryos from whi...
متن کاملFluorescent and Bioluminescent Reporter Myxoviruses
The advent of virus reverse genetics has enabled the incorporation of genetically encoded reporter proteins into replication-competent viruses. These reporters include fluorescent proteins which have intrinsic chromophores that absorb light and re-emit it at lower wavelengths, and bioluminescent proteins which are luciferase enzymes that react with substrates to produce visible light. The incor...
متن کاملInactivation of myxoviruses by calcium elenolate.
Calcium elenolate inactivates all myxoviruses so far tested. The pH of the reaction mixture is less critical for myxovirus inactivation than that required for coxsackie A-21 virus; the myxoviruses are inactivated at a broad spectrum of pH with the maximum activity occurring at a pH below 7.0. The infectivity of the virus is more susceptible to the action of calcium elenolate than is either the ...
متن کاملRecovery and identification of human myxoviruses.
The myxoviruses which infect man can be divided into two major subgroups (Table 1): the influenza subgroup which includes influenza virus types A, B, and C and the noninfluenza subgroup which includes parainfluenza types 1 (HA-2), 2 (CA), 3 (HA-1), and 4, mumps, measles, and respiratory syncytial viruses. Related but distinct antigenic variants or subtypes have been detected among types of both...
متن کاملStudies of Parainfluenza Viruses
Serologic cross reactions have been demonstrated between members of the parainfluenza subgroup of myxoviruses.7'-Similar antigenic relationships have also been noted between mumps virus and each of the four parainfluenza virus serotyes" and between mumps and Newcastle disease virus.7'8 Furthermore, the DA virus, § a myxovirus recently isolated from human blood, which is serologically indistingu...
