Summary
Virus interference, where one virus inhibits another, offers a natural defense against infections in various hosts. This phenomenon is being revisited for potential applications in aquaculture and medicine.
Area of Science:
- Virology
- Immunology
- Aquaculture
Background:
- Virus interference is a natural phenomenon where co-infecting viruses modulate each other's replication within a host.
- Historically studied from the 18th century, research intensified between 1930-1960, focusing on bacterial and vertebrate viruses.
- Pathogenic viruses involved in interference impact human and animal health, suggesting therapeutic potential.
Purpose of the Study:
- To review the historical context and scientific understanding of virus interference.
- To highlight recent research on virus interference in commercially important farmed aquatic species, particularly crustaceans.
- To emphasize the potential of virus interference as an alternative to chemical therapies.
Main Methods:
- Historical literature review of virus interference studies.
- Analysis of experimental data from in vivo, tissue, and cell culture assays.
- Examination of recent studies on virus interference in crustacean aquaculture.
Main Results:
- Virus interference has been observed across diverse hosts, including bacteria, vertebrates, and invertebrates.
- Certain viruses affecting farmed crustaceans exhibit interference phenomena.
- Interference can significantly reduce the severity and mortality caused by superinfecting viruses.
Conclusions:
- Virus interference presents a promising avenue for developing novel, non-chemical therapeutic strategies against viral diseases.
- Further research into virus interference in aquaculture is crucial for disease management and sustainable production.
- Understanding interference mechanisms can lead to innovative approaches in both medicine and animal health.

Viruses of Archaea
210
Archaeal viruses play a crucial role in the ecosystems of extremophilic archaea, particularly those belonging to the phyla Euryarchaeota and Crenarchaeota. By shaping host evolution and facilitating gene transfer, these viruses influence microbial communities and contribute to genetic diversity in extreme environments. The archaea they infect thrive in acidic hot springs and hydrothermal vents characterized by high temperatures and low pH. Archaeal viruses exhibit remarkable structural...

CRISPR and crRNAs
18.0K
Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

Retroviruses
13.2K
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’...

The Antiviral System of Bacteria and Archaea: CRISPR
324
CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats is a adaptive immune system found in bacteria and archaea that protects against viral infections. This system enables prokaryotic cells to identify, remember, and neutralize foreign genetic elements, primarily bacteriophages, by storing fragments of the invader’s DNA as a genetic memory.The CRISPR immune response begins during an initial infection. Cas (CRISPR-associated) proteins play a central role in this...

Viral Recombination
24.1K
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.

Introduction to Virus
552
Viruses are unique biological entities that blur the boundary between living and non-living systems. Although they lack cellular structure and metabolic processes, they can exhibit characteristics of life when infecting a host. Their defining feature is a nucleic acid core, composed of either DNA or RNA, encapsulated within a protein coat called a capsid. This simple structure allows them to invade host cells and use their machinery for replication efficiently.Viral Structure and...
