Three G3P[9] rotaviruses, detected in children hospitalized with gastroenteritis in Palermo, Italy, were found to be genetically related to strains of either human or feline origin in the VP7, VP4, and VP6 genes. In contrast, in the NSP4 gene the viruses resembled G2P[4] human strains, suggesting a reassortment between AU-1-like and Kun-like strains.

results phylogenetic analysis of the gene revealed that pakistani 1a hcv strains are in the start of third cluster and there is a difference between inter pakistani isolates at primary, secondary and tertiary levels. material and methods patient sera infected with hepatitis c virus, genotype 1a, were obtained from molecular diagnostics lab, cemb, university of the punjab lahore by using bd vacu...

Cloning and expression of hepatitis C virus have allowed the development of immunoassays to detect hepatitis C virus infection. However, currently available recombinant fusion protein C100-3 assays, based on a nonstructural protein of the virus, are limited in sensitivity, particularly for detecting acute infection. In this report seroconversion panels showed that an assay based on synthetic pe...

The small mRNA (SmRNA) of all Bunyaviridae encodes the nucleocapsid (N) protein. In 4 out of 5 genera in the Bunyaviridae, the smRNA encodes an additional nonstructural protein denominated NSs. In this study, we show that Andes hantavirus (ANDV) SmRNA encodes an NSs protein. Data show that the NSs protein is expressed in the context of an ANDV infection. Additionally, our results suggest that t...

Hepatitis C virus infection is causing chronic liver disease, cirrhosis, and hepatocellular carcinoma. By combining direct-acting antivirals (DAAs), high sustained virologic response rates (SVRs) can be achieved. Resistance-associated substitutions (RASs) are commonly observed after DAA failure, especially nonstructural protein 5A (NS5A) RASs may impact retreatment options.1–3 Data on of failur...

OBJECTIVE The aim of the present study was to characterize 24 isolates of group C rotavirus (RV-C) by analysis of DNA sequences of the VP4, VP6, VP7 and NSP4 genes of several Brazilian states. METHODS All RV-C strains were confirmed by polyacrylamide gel electrophoresis and were characterized by sequence and phylogenetic analysis of the genes encoding NSP4, VP6, VP4, and VP7 proteins. RESUL...
