A Novel Marsupial Hepatitis A Virus Corroborates Complex Evolutionary Patterns Shaping the Genus Hepatovirus [PDF]

Journal of Virology, 2018
ABSTRACT The discovery of highly diverse nonprimate hepatoviruses illuminated the evolutionary origins of hepatitis A virus (HAV) ancestors in mammals other than primates. Marsupials are ancient mammals that diverged from other Eutheria during the Jurassic.

Seasonal dynamics of the wild rodent faecal virome

Molecular Ecology, Volume 32, Issue 17, Page 4763-4776, September 2023., 2023
Abstract Viral discovery studies in wild animals often rely on cross‐sectional surveys at a single time point. As a result, our understanding of the temporal stability of wild animal viromes remains poorly resolved. While studies of single host–virus systems indicate that host and environmental factors influence seasonal virus transmission dynamics ...

Phosphorylation of enteroviral 2Apro at Ser/Thr125 benefits its proteolytic activity and viral pathogenesis

Journal of Medical Virology, Volume 95, Issue 1, January 2023., 2023
Abstract Enteroviral 2A proteinase (2Apro), a well‐established and important viral functional protein, plays a key role in shutting down cellular cap‐dependent translation, mainly via its proteolytic activity, and creating optimal conditions for Enterovirus survival.

Hepatitis A: Viral Structure, Classification, Life Cycle, Clinical Symptoms, Diagnosis Error, and Vaccination

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2023, Issue 1, 2023., 2023
Hepatitis A virus (HAV) is one of the well‐known viruses that cause hepatitis all around the globe. Although this illness has decreased in developed countries due to extensive immunization, numerous developing and under‐developed countries are struggling with this virus.

Viral hepatitis in pregnancy

Journal of Viral Hepatitis, Volume 29, Issue 10, Page 844-861, October 2022., 2022
Abstract Viral hepatitis is caused by a heterogenous group of viral agents representing a wide range of phylogenetic groups. Many viruses can involve the liver and cause liver injury but only a subset are delineated as ‘hepatitis viruses’ based upon their primary site of replication and tropism for hepatocytes which make up the bulk of the liver cell ...

Picornavirus translation strategies

FEBS Open Bio, Volume 12, Issue 6, Page 1125-1141, June 2022., 2022
Upon the entry of the viral RNA into susceptible cells, cis‐ and trans‐regulatory elements coordinately determine picornavirus protein synthesis. Early in the infection, the cap‐dependent translation of host mRNAs is shut down, while viral RNA takes advantage of the IRES element, resulting in efficient synthesis of viral proteins.

Hepatitis B virus genotype is an independent prognostic factor of telbivudine and tenofovir treatment in hepatitis B surface antigen‐positive pregnant women

Food Science &Nutrition, Volume 10, Issue 1, Page 3-11, January 2022., 2022
Abstract To investigate whether HBV genotype influences the effect of tenofovir and telbivudine on HBV DNA and RNA levels in HBsAg‐positive pregnant women. This was a retrospective study of 74 HBsAg‐positive pregnant women in Guizhou of China. All patients were treated with telbivudine or tenofovir from 12 weeks of pregnancy and HBV infection to the ...

Hepatitis A and E Viruses in Mussels from Cherrat Estuary in Morocco: Detection by Real‐Time Reverse Transcription PCR Analysis

Advances in Virology, Volume 2022, Issue 1, 2022., 2022
The aim of the present study was to evaluate hepatitis A virus (HAV) and hepatitis E virus (HEV) contamination in mussels (Mytilus galloprovincialis) from Cherrat estuary (Moroccan Atlantic Coast), Morocco. In total, 52 samples (n = 12 mussels/each) were collected at four sites in the estuary, monthly, between March 2019 and March 2020.

TIM1 (HAVCR1) Is Not Essential for Cellular Entry of Either Quasi-enveloped or Naked Hepatitis A Virions

mBio, 2017
Receptor molecules play key roles in the cellular entry of picornaviruses, and TIM1 (HAVCR1) is widely accepted to be the receptor for hepatitis A virus (HAV), an unusual, hepatotropic human picornavirus.
