Hepatitis01:25

Hepatitis

34
Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver.

Subviral Agents01:29

Subviral Agents

739
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Viruses with RNA Genomes01:29

Viruses with RNA Genomes

1.3K
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Human Virome01:26

Human Virome

32
The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible...

Size and Structure of Viral Genomes01:26

Size and Structure of Viral Genomes

1.0K
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...

Viruses of Archaea01:29

Viruses of Archaea

644
Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

Area of Science:

  • Virology
  • Genomics
  • Infectious Diseases

Background:

  • The nomenclature of hepatitis E virus (HEV) subtypes is inconsistent.
  • This inconsistency complicates the comparison of findings across different research studies.

Purpose of the Study:

  • To propose a standardized system for HEV subtyping.
  • To provide a table of proposed complete genome reference sequences for each HEV subtype.
  • To facilitate clearer communication and epidemiological studies of HEV.

Main Methods:

  • A conservative and pragmatic approach was used for subtype assignment.
  • Criteria for subtype assignment were based on variations in genotypes and methodologies.

Main Results:

  • A table of proposed complete genome reference sequences for each HEV subtype has been provided.
  • The proposed subtyping procedure is intended to be adopted by the scientific community.

Conclusions:

  • Standardized HEV reference sequences will improve communication among researchers.
  • This standardization will aid in clarifying the epidemiology of HEV.
  • The proposed subtyping procedure may be applicable to other viruses within the Orthohepevirus genus.
