Next generation sequencing technologies: tool to study avian virus diversity
Acta Virologica
|March 20, 2015
Summary
Next-generation sequencing (NGS) aids in discovering novel avian viruses, crucial for understanding emerging infectious diseases. This technology improves diagnosis and disease control in avian populations facing global health threats.
Area of Science:
- Veterinary Virology
- Infectious Disease Epidemiology
- Genomics
Background:
- Global changes (climate, wildlife-livestock interfaces) drive novel zoonotic viral emergence.
- Avian biodiversity and migration act as reservoirs and vectors for infectious disease spread.
- Classical diagnostics struggle to identify novel or variant viruses, hindering timely disease management.
Purpose of the Study:
- To review next-generation sequencing (NGS) methodologies for novel avian virus discovery.
- To highlight NGS's utility in characterizing avian viral diversity.
- To explore viral-host interactions and disease causality of newly identified avian viruses.
Main Methods:
- Sequence-independent amplification techniques.
- High-throughput sequencing platforms.
- Bioinformatic analysis pipelines for viral identification.
Main Results:
- NGS enables culture-independent identification and characterization of avian viruses.
- Discovery of novel viruses including picobirnavirus, picornavirus, orthoreovirus, and avian gamma coronavirus.
- Demonstration of NGS in describing broad viral diversity across avian species.
Conclusions:
- NGS is a powerful tool for discovering novel avian viruses and understanding viral diversity.
- Advances in NGS facilitate improved diagnosis and control of avian infectious diseases.
- Further research into viral-host interactions is essential for managing newly identified pathogens.

Next-generation Sequencing
102.0K
The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.

RNA-seq
12.7K
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

Viral Mutations
41.0K
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...

Advancements in molecular biology have revolutionized the identification and characterization of bacteria, with multiple methods leveraging DNA sequencing for enhanced precision. As sequencing technologies improve and costs decline, these approaches are increasingly used in clinical, environmental, and evolutionary studies.Multilocus Sequence Typing (MLST) examines several housekeeping genes, essential chromosomal genes encoding cellular functions, to distinguish strains. Approximately...

Sanger Sequencing
780.5K
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

Multi-species Conserved Sequences
5.0K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...
