Insights

We sequenced the infectious bronchitis virus (IBV) strain VFAR-047 from Peru. This avian virus belongs to the GI-16 lineage and shows evidence of recombination with other IBV strains.

Area of Science:

  • Veterinary Virology
  • Molecular Epidemiology
  • Genomics

Background:

  • Infectious bronchitis virus (IBV) is a highly contagious avian coronavirus that causes significant economic losses in the poultry industry worldwide.
  • IBV is classified into different lineages based on genetic and antigenic properties, necessitating continuous surveillance and characterization of circulating strains.
  • Understanding the genetic diversity and evolution of IBV is crucial for developing effective control strategies.

Purpose of the Study:

  • To report the near-complete genome sequence of a novel infectious bronchitis virus (IBV) strain, VFAR-047, isolated in Peru.
  • To determine the phylogenetic classification of the IBV VFAR-047 strain.
  • To investigate potential genetic recombination events within the IBV VFAR-047 strain.

Main Methods:

  • Whole-genome sequencing of the IBV VFAR-047 strain.
  • Phylogenetic analysis based on complete genome and Spike 1 (S1) gene sequences.
  • Recombination analysis to identify potential parental strains.

Main Results:

  • The near-complete genome sequence of IBV strain VFAR-047 was successfully obtained.
  • Phylogenetic analysis placed strain VFAR-047 within the GI lineage 16 (GI-16) of IBV.
  • Four potential recombination events were identified, involving other GI-16 and GI-11 IBV strains.

Conclusions:

  • The characterization of IBV strain VFAR-047 provides valuable genomic data from Peru.
  • The classification into GI-16 highlights the genetic diversity of IBV in the region.
  • The identified recombination events suggest complex evolutionary dynamics and potential for rapid adaptation of IBV strains.

Viruses with RNA Genomes

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Genomics

Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...

Genome Size and the Evolution of New Genes

While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Cattell's 16 Personality Factors

Raymond Cattell's trait theory offers a structured framework for understanding personality by distinguishing between two critical traits: surface and source traits. Surface traits are observable patterns of behavior, such as indecisiveness, anxiety, and irrational fears. These traits are less stable, varying across situations and over time. This means that they are less helpful in understanding the deeper aspects of an individual's personality.
In contrast, source traits are the...

Genomic Imprinting and Inheritance02:30

Genomic Imprinting and Inheritance

Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...
