Viral Recombination00:57

Viral Recombination

25.6K
Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

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...

Retroviruses02:33

Retroviruses

15.7K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Cytomegalovirus Disease01:27

Cytomegalovirus Disease

11
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...

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...

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

50.5K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

Summary
This summary is machine-generated.

Human parechoviruses (HPeVs), particularly HPeV3, can cause severe illness like sepsis and meningoencephalitis in infants. Lack of maternal antibodies is a risk factor, and further research into HPeV3 pathogenesis and therapy is crucial.

Area of Science:

  • Virology
  • Infectious Diseases
  • Pediatrics

Background:

  • Human parechoviruses (HPeVs) are RNA viruses in the Picornaviridae family.
  • Initially associated with mild illness, HPeV3 discovery revealed potential for severe infant infections.
  • HPeV3 causes sepsis and meningoencephalitis in neonates and young infants.

Purpose of the Study:

  • To highlight the emerging threat of HPeV3 infections in infants.
  • To discuss the clinical presentation and risk factors for severe HPeV3 disease.
  • To emphasize the need for further research into HPeV3.

Main Methods:

  • Review of HPeV3 epidemiology and clinical manifestations.
  • Discussion of diagnostic methods, primarily PCR.
  • Analysis of potential risk factors, including maternal antibody titers.

Main Results:

  • HPeV3 epidemics occur periodically in Japan.
  • Typical symptoms include fever, tachycardia, and poor activity; severe cases can lead to death.
  • Low or absent maternal neutralizing antibodies are a suspected risk factor for severe disease.

Conclusions:

  • HPeV3 poses a significant risk to neonates and young infants.
  • Supportive care is the current management strategy; no specific antiviral therapy exists.
  • Urgent research is needed for HPeV3 pathogenesis, therapy, and prevention.
