Insights

Six new Staphylococcus pseudintermedius prophage genomes from the Siphoviridae family were identified. These bacterial viruses were found in clinical samples from both humans and dogs, highlighting potential zoonotic transmission routes.

Area of Science:

  • Microbiology
  • Virology
  • Genomics

Background:

  • Staphylococcus pseudintermedius is a significant bacterial pathogen in veterinary medicine.
  • This bacterium possesses zoonotic potential, posing risks to human health.
  • Bacteriophages, viruses that infect bacteria, play crucial roles in microbial ecology and evolution.

Purpose of the Study:

  • To characterize novel prophage genomes from Staphylococcus pseudintermedius.
  • To investigate the genetic diversity of Siphoviridae family phages associated with this pathogen.
  • To explore the implications of these prophages in the context of S. pseudintermedius infections in companion animals and humans.

Main Methods:

  • Whole-genome sequencing of bacterial isolates.
  • Bioinformatic analysis for prophage genome identification and assembly.
  • Phylogenetic analysis to determine phage relationships within the Siphoviridae family.

Main Results:

  • Six complete prophage genomes belonging to the Siphoviridae family were identified.
  • These prophages were found integrated within the genomes of S. pseudintermedius isolates.
  • The identified prophages originated from clinical specimens of both canine and human origin.

Conclusions:

  • The discovery of new S. pseudintermedius prophages expands our understanding of phage diversity.
  • These findings provide insights into the genetic makeup of phages associated with a common veterinary pathogen.
  • The presence of these prophages in both canine and human isolates warrants further investigation into their role in bacterial virulence and zoonotic potential.

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...

Comparing Mitochondrial, Chloroplast, and Prokaryotic Genomes

The present-day mitochondrial and chloroplast genomes have retained some of the characteristics of their ancestral prokaryotes and also have acquired new attributes during their evolution within eukaryotic cells. Like prokaryotic genomes, mitochondrial and chloroplast genomes neither bind with histone-like proteins nor show complex packaging into chromosome-like structures, as observed in eukaryotes. Unlike mitotic cell divisions observed in eukaryotic cells, mitochondria and chloroplasts...

Genome Size and the Evolution of New Genes03:21

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.

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...

Cis-regulatory Sequences02:02

Cis-regulatory Sequences

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...
