Summary
Genomic surveillance of the mpox virus (MPXV) in Australia detected local transmission and within-host diversity. This study enhances understanding of MPXV evolution and informs public health strategies during the global mpox outbreak.
Area of Science:
- Genomics
- Epidemiology
- Virology
Background:
- Infectious disease outbreaks necessitate genomic surveillance for effective public health responses.
- Genomic data on the 2022 mpox virus (MPXV) outbreak is limited, particularly from South-East Asia and the Western Pacific.
- Previous studies focused on high-incidence regions, leaving gaps in understanding global viral spread.
Purpose of the Study:
- To analyze the genomic diversity of MPXV in Melbourne, Australia.
- To identify local transmission patterns and within-host viral evolution.
- To contribute crucial genomic data from the Western Pacific region to the global mpox surveillance effort.
Main Methods:
- Whole-genome sequencing of 102 MPXV samples from 56 individuals.
- Phylogenetic analysis to determine viral lineage and transmission.
- Analysis of within-host diversity, co-infections, and structural variations.
Main Results:
- All sequenced genomes belonged to the 2022 MPXV outbreak lineage (B.1).
- Evidence of likely local transmission within Melbourne was detected.
- Within-host diversity, co-infections, and apolipoprotein B editing complex-driven micro-evolution were observed.
Conclusions:
- Genomic surveillance in Australia provides critical insights into MPXV spread and evolution.
- Understanding MPXV micro-evolution and diversification is vital for public health interventions.
- This study contributes to monitoring the evolutionary trajectory of MPXV during the ongoing outbreak.

00:36Viral Mutations
32.4K
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...

01:25Genetic Variation
323
Genetic variation is the diversity in DNA sequences found among individuals of the same species. This diversity is crucial for a species' survival because it helps organisms adapt to environmental changes. Genetic variation begins with fertilization, where an egg and sperm cell merge. Each of these cells carries 23 chromosomes, up to 46 in the fertilized egg. Chromosomes are long DNA strands that contain genes, the basic units of heredity.

01:28Diversity of Antigen Receptors
633
Antigen receptors are essential components of the immune system crucial in defending the body against foreign invaders. These receptors are present on the surface of B and T cells, enabling them to recognize antigens and mount an appropriate immune response.
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

00:57Viral Recombination
23.5K
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.

01:05Single Nucleotide Polymorphisms-SNPs
15.3K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

00:58Genomic DNA in Eukaryotes
47.0K
Eukaryotes have large genomes compared to prokaryotes. To fit their genomes into a cell, eukaryotic DNA is packaged extraordinarily tightly inside the nucleus. To achieve this, DNA is tightly wound around proteins called histones, which are packaged into nucleosomes that are joined by linker DNA and coil into chromatin fibers. Additional fibrous proteins further compact the chromatin, which is recognizable as chromosomes during certain phases of cell division.
