Insights

Simian foamy virus (SFV) can transmit from macaques to humans, a finding supported by antibody and DNA evidence in primate facility workers. This discovery has significant public health and occupational safety implications.

Area of Science:

  • Virology
  • Primate Research
  • Public Health

Background:

  • Cross-species transmission of simian foamy virus (SFV) from non-human primates like chimpanzees, baboons, and African green monkeys to humans is documented.
  • Macaques are extensively used in biomedical research, yet human SFV infection originating from macaques has not been previously reported.

Purpose of the Study:

  • To investigate the potential for simian foamy virus (SFV) transmission from macaques to humans working in primate facilities.
  • To identify and characterize SFV infection in human populations with occupational exposure to macaques.

Main Methods:

  • Serological testing using immunoblots with macaque foamy virus antigens to detect antibodies in primate facility workers.
  • Phylogenetic analysis of amplified proviral DNA from peripheral blood mononuclear cells of infected individuals.

Main Results:

  • Two out of 46 primate facility workers tested positive for antibodies reactive to macaque foamy virus antigens.
  • Phylogenetic analysis of a DNA fragment from one infected individual indicated SFV infection of macaque origin.

Conclusions:

  • Human infection with simian foamy virus (SFV) originating from macaques is possible.
  • The findings highlight potential public health and occupational safety concerns due to macaque-to-human SFV transmission in research settings.

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

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 retrovirus to...
Viral Recombination00:57

Viral 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.
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...
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’...

Mechanisms of Retrovirus-induced Cancers

Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...
Rabies01:28

Rabies

Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
