Partly 5` Untranslated Region (5` UTR)-Based Phylogenetic Analysis of Three Hepatitis C Virus Isolates From Jakarta, Indonesia: a Preliminary Study [PDF]
, 2014 Currently, we reported results of a nested PCR assay specific 5` UTR region of HCV genome that showed three different patterns of DNA fragments (single expected specific DNA band, single DNA band higher in size than an expected band, and multiple DNA ...

Virulence in murine model shows the existence of two distinct populations of Brazilian Vaccinia virus strains. [PDF]
PLoS ONE, 2008 Brazilian Vaccinia virus had been isolated from sentinel mice, rodents and recently from humans, cows and calves during outbreaks on dairy farms in several rural areas in Brazil, leading to high economic and social impact.

Impact of RNA Virus Evolution on Quasispecies Formation and Virulence
International Journal of Molecular Sciences, 2019 RNA viruses are known to replicate by low fidelity polymerases and have high mutation rates whereby the resulting virus population tends to exist as a distribution of mutants.

Dengue Virus Markers of Virulence and Pathogenicity [PDF]
Future Virology, 2009 The increased spread of dengue fever and its more severe form, dengue hemorrhagic fever, have made the study of the mosquito-borne dengue viruses that cause these diseases a public health priority. Little is known about how or why the four different (serotypes 1-4) dengue viruses cause pathology in humans only, and there have been no animal models of ...

Genomic polymorphism of the pandemic A (H1N1) influenza viruses correlates with viral replication, virulence, and pathogenicity in vitro and in vivo. [PDF]
PLoS ONE, 2011 The novel pandemic A (H1N1) virus was first identified in Mexico in April 2009 and quickly spread worldwide. Like all influenzas, the H1N1 strain-specific properties of replication, virulence, and pathogenicity are a result of the particular genomic ...

Tobacco mosaic virus virulence and avirulence
Philosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 1999 In celebration of a century of research on tobacco mosaic virus that initiated the science of virology, I review recent progress relative to earlier contributions concerning how viruses cause diseases of plants and how plants defend themselves from viruses.
