Insights

Bordetella parapertussis rarely causes severe disease, but this study reports an unusual case of bacteremia. Genomic analysis compared this isolate to others from respiratory infections.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Genomics

Background:

  • Whooping cough is primarily caused by Bordetella pertussis.
  • Bordetella parapertussis, a related species, typically causes milder illness.
  • Bacteremia due to B. parapertussis is uncommon.

Purpose of the Study:

  • To report an unusual case of B. parapertussis bacteremia.
  • To review existing literature on B. parapertussis infections.
  • To perform genomic characterization of the B. parapertussis isolate.

Main Methods:

  • Case report of bacteremia.
  • Literature review.
  • Whole-genome sequencing and comparative genomic analysis.

Main Results:

  • An unusual case of B. parapertussis bacteremia was identified.
  • Genomic sequencing revealed specific characteristics of the isolate.
  • Comparison with other B. parapertussis strains provided insights into genomic diversity.

Conclusions:

  • B. parapertussis can cause severe disease, including bacteremia, although rare.
  • Genomic analysis aids in understanding the pathogenicity and evolution of B. parapertussis.
  • Further research is warranted to elucidate the clinical significance of B. parapertussis genomic variations.

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...

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...

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...

Bacterial Signaling01:30

Bacterial Signaling

Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

What is Gene Expression?01:42

What is Gene Expression?

Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

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.
