Viral Mutations00:36

Viral Mutations

A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material for adaptive...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Malaria01:29

Malaria

Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
Retroviruses02:33

Retroviruses

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’...
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...

Area of Science:

  • Virology
  • Ecology
  • Epidemiology

Background:

  • Usutu virus (USUV) was first identified in South Africa in 1959.
  • USUV has since been detected across multiple African nations and emerged in Europe in 2001, causing significant mortality in birds.
  • Human infections with USUV in Europe, first reported in 2009, have led to encephalitis, particularly in immunocompromised individuals.

Purpose of the Study:

  • To review the emergence and spread of Usutu virus (USUV) in Africa.
  • To summarize available data on USUV isolations, host range, and potential vectors.
  • To enhance understanding of the ecological factors driving USUV circulation in Africa and Europe.

Main Methods:

  • Literature review of published data on Usutu virus.
  • Compilation of records on USUV isolations and geographical distribution.
  • Analysis of host range and vector data in African regions.

Main Results:

  • USUV has a documented presence in numerous African countries, with *Culex* mosquitoes and birds as primary hosts.
  • The virus's introduction to Europe in 2001 marked a significant expansion of its geographical range.
  • Human cases in Europe highlight USUV's potential as a human pathogen, causing severe neurological illness.

Conclusions:

  • Investigating the natural history and ecology of USUV in Africa is crucial due to its potential as a human pathogen.
  • Understanding African USUV ecology can inform strategies to mitigate risks associated with its spread and impact in Europe and beyond.
  • Further research is needed to fully elucidate the factors governing USUV transmission dynamics.
