Incorporation of the influenza A virus NA segment into virions does not require cognate non-coding sequences.
replaced by those of the seven other segments. Recombinant viruses harbouring two segments with identical NC sequences were successfully rescued. Virus growth kinetics and serial passages were performed, and ...
A multiplex oligonucleotide ligation-PCR as a complementary tool for subtyping of Salmonella Typhimurium
markers was confirmed in a serial passage experiment. The validation of the MOL- PCR assay for subtyping of S. Typhimurium and S. 1,4,[5],12:i:- on 519 isolates shows that the method is rapid, reproducible, ...
Multi locus variable-number tandem repeat (MLVA) typing tools improved the surveillance of Salmonella enteritidis: a 6 years retrospective study.
antibiotics tested. 172 different MLVA profiles were detected, of which 9 frequent profiles included 67.2% of the S. Enteritidis population. During a serial passage experiment on selected isolates to ...
MLVA as a tool for public health surveillance of human Salmonella Typhimurium: prospective study in Belgium and evaluation of MLVA loci stability.
During a serial passage experiment on selected isolates to investigate the in vitro stability of the 5 MLVA loci, variations over time were observed for loci STTR6, STTR10, STTR5 and STTR9. This study ...
Influenza A strain-dependent pathogenesis in fatal H1N1 and H5N1 subtype infections of mice.
pathogenesis, we compared 2 different influenza A virus subtypes, H1N1 and H5N1. The subtypes, which had shown no pathogenicity in laboratory mice, were forced to evolve by serial passaging. Although both adapted ...
Imidazo[4,5-c]pyridines inhibit the in vitro replication of the classical swine fever virus and target the viral polymerase.
virus was selected by serial passage of the virus in increasing drug-concentration. The BPIP-resistant virus (EC (50): 24+/-4.0 microM) proved cross-resistant with VP32947 ...
Genetic variability of encephalomyocarditis virus (EMCV) isolates.
Sequence Homology Serial Passage Swine Swine Diseases Viral Proteins Abstract: In order to evaluate the variability of encephalomyocarditis virus (EMCV), field isolates originating from different European ...
Molecular study of the quasispecies evolution of a typical pigeon paramyxovirus type 1 after serial passages in pigeons by contact.
Evolution, Molecular Genes, Viral Kidney Molecular Sequence Data Newcastle disease virus polymerase chain reaction Sequence Alignment Sequence Homology, Nucleic Acid Serial Passage Abstract: The quasispecies ...
Molecular analysis of the capsid coding region of a virulent encephalomyocarditis virus isolate after serial cell passages and assessment of its virulence.
Cells, Cultured Encephalomyocarditis virus Genome, Viral Models, Molecular Mutation Serial Passage Swine Vaccines, Attenuated virulence Abstract: EMCV has been recognized as a worldwide-shared pathogen in ...
Replicative fitness recuperation of a recombinant murine norovirus- reciprocity of genetic shift and drift.
growth kinetics and plaque size differences between viral progenies prior to and post serial passaging. Point mutations at consensus and sub-consensus population levels of early and late viral progenies ...
