Abstract

Insights

A novel gemycircularvirus, GeTz1, was found in a child with encephalitis. This discovery highlights the need to investigate gemycircularvirus infections in humans and their potential link to neurological conditions.

Area of Science:

  • Virology
  • Genomics
  • Infectious Diseases

Background:

  • Circular, replication initiator protein (Rep) encoding, single-stranded DNA (CRESS-DNA) viruses are found across diverse eukaryotic organisms.
  • Gemycircularvirus represents a distinct group within CRESS-DNA viruses.

Purpose of the Study:

  • To characterize a novel gemycircularvirus identified in a human cerebrospinal fluid sample.
  • To investigate the potential role of gemycircularviruses in unexplained encephalitis.

Main Methods:

  • Whole genome sequencing and characterization of the novel virus.
  • Phylogenetic analysis of viral proteins (Rep and Cap).

Main Results:

  • A novel gemycircularvirus, designated GeTz1, was identified from the cerebrospinal fluid of a child with encephalitis.
  • GeTz1 encodes two main proteins: a capsid protein (Cap) and a replication-associated protein (Rep).
  • Phylogenetic analysis showed GeTz1 clusters with a known avian gemycircularvirus, sharing 46.6% amino acid identity in the Rep protein.

Conclusions:

  • A novel gemycircularvirus was discovered in a human encephalitis case.
  • Further research is warranted to determine if gemycircularviruses infect humans and are associated with encephalitis.
  • Investigating human sera for specific antibodies against gemycircularviruses is recommended.

Arboviral Encephalitis01:25

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Bacterial Gastroenteritis01:18

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid...

Viruses with RNA Genomes01:29

Viruses with RNA Genomes

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...

Subviral Agents01:29

Subviral Agents

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...
