Viral Mutations

32.3K
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...

Viral Recombination00:57

Viral Recombination

23.4K
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.

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

45.9K
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...

Retroviruses

12.2K
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’...

Infection01:20

Infection

7.9K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

    Area of Science:

    • Veterinary epidemiology
    • Zoonotic disease research
    • Wildlife health surveillance

    Background:

    • Understanding the transmission dynamics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is critical for public health.
    • The potential for SARS-CoV-2 to spill over into and circulate within diverse animal populations remains a significant concern.
    • A comprehensive approach is needed to identify animal reservoirs and transmission pathways.

    Discussion:

    • This project will investigate the prevalence and genetic diversity of SARS-CoV-2 in various wild animal species.
    • Sampling will encompass a wide range of taxa, including mammals, birds, and potentially other groups, across different geographic regions.
    • Data will be analyzed to identify potential animal hosts and understand the ecological and behavioral factors influencing virus transmission.

    Key Insights:

    • Early findings will help elucidate the role of wildlife in the ongoing COVID-19 pandemic.
    • Identifying specific animal species involved in SARS-CoV-2 transmission is essential for targeted surveillance and control strategies.
    • This research will contribute valuable data to the global effort to monitor and manage zoonotic diseases.

    Outlook:

    • The project's findings will inform strategies for mitigating human-wildlife transmission of SARS-CoV-2.
    • Results may guide the development of One Health approaches to prevent future zoonotic spillover events.
    • Long-term monitoring of animal populations will be essential for detecting emerging infectious diseases.
