Sequence similarities between human bornavirus isolates and laboratory strains question human origin
Lancet (London, England)
|January 6, 2000
Summary
Human bornavirus RW98 closely matches a lab rat strain, unlike previous human isolates. This suggests many identified human bornaviruses may originate from laboratory experiments, not natural human infections.
Area of Science:
- * Virology
- * Molecular Biology
- * Zoonotic Disease Research
Background:
- * The human bornavirus RW98 isolate exhibits a genome with only 3-4% divergence from previously identified strains.
- * This novel isolate demonstrates near-identical genetic makeup to a laboratory-adapted rat strain.
Discussion:
- * The genetic similarity between human bornavirus isolates and laboratory strains raises questions about their true origin.
- * This challenges the assumption of naturally acquired human bornavirus infections, suggesting potential laboratory contamination or artifact.
Key Insights:
- * Bornavirus RW98's close relationship to a rat-adapted strain.
- * Genetic similarities among reported human bornaviruses and experimental strains.
- * Potential for laboratory artifacts to be misidentified as naturally occurring human infections.
Outlook:
- * Re-evaluation of previously identified human bornavirus isolates is warranted.
- * Future research should implement stringent controls to differentiate between natural and laboratory-associated strains.
- * This necessitates a revised understanding of bornavirus epidemiology and transmission in humans.

00:57Viral Recombination
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.
00:36Viral 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...
02:33Retroviruses
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’...
01:29Viruses 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...
01:26Human Virome
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 only with...
01:29Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
