Mumps vaccine viruses, Leningrad-3 (L-3) strain, harvested at the 8th (8P) and 38th (38P) passage levels, were compared by nucleotide sequencing of the fusion (F) and the phosphoprotein (P) genes, and for replication efficiency in cell culture. Sequencing revealed only one clear base substitution throughout the entire F gene, and no substitutions in the(More)
The results of immunofluorescent (IF) and immunoperoxidase (IP) technics applied for the detection of antigen in cerebrospinal fluid (CSF) cells in patients with mumps, herpes zoster and herpes simplex meningitis and meningoencephalitis are presented. Thirty patients were under study. The detection of mumps and herpes zoster viral antigen in CSF cells was(More)
Small-scale measles and mumps virus propagation in microcarrier-grown cells was studied to assess putative advantages over conventional roller-type virus propagation. Significantly higher virus yields could not be attained with microcarrier cultures in cell stirrers, therefore making the advantages purely technological. The pattern of measles virus(More)
Invasiveness of mumps virus strains, differing in the degree of attenuation was studied in green and Macaca mulatta monkeys infected either into salivary glands or intramuscularly. Peripheral infection with all strains under study resulted in their penetration into CNS irrespective of the attenuation degree. Specific morphological changes were observed in(More)
The degree of attenuation of mumps virus was studied in intracerebrally inoculated Macaca mulatta monkeys. The virulent Leningrad-3 strain and its attenuated variant as well as the attenuated Sophia-6 strain were used. The nature of pathological alterations in the neurons pointed to neurotropism of only the virulent strain. Morphological changes caused by(More)
The properties of mumps vaccine virus (Leningrad-3 strain) gradually changed upon passaging in quail embryo fibroblasts, the substrate normally used for mumps vaccine production in the USSR. Alterations were extremely noticeable in the over-attenuated (38th passage) virus variant, and involved (a) poor, if any, antibody response in guinea-pigs, (b) turbid(More)
The great progress made in the field of virology has hardly affected the section of the chemotherapy and chemoprophylaxis of virus infections. Against the overwhelming majority of virus diseases no antibiotics or chemotherapeutic preparations are available, administration of which gives rise to a prophylactic or therapeutic effect. However, the attention of(More)
