Insights

Genome sequencing of two opportunistic Staphylococcus cohnii strains reveals new Staphylococcal Cassette Chromosome mec. These findings shed light on antibiotic resistance in human infections.

Area of Science:

  • Microbiology
  • Genomics
  • Infectious Diseases

Background:

  • Staphylococcus cohnii is an opportunistic pathogen.
  • Understanding its genome is crucial for combating infections.

Observation:

  • Two S. cohnii strains (SC-57, SC-532) were isolated from human blood and catheter samples.
  • Both strains exhibited low biofilm production and increased antibiotic resistance linked to biofilms.

Findings:

  • Draft genome sequences and annotations for both S. cohnii strains were generated.
  • Genes involved in metabolism (42%) and virulence (4%) were identified.
  • A novel Staphylococcal Cassette Chromosome mec (SCCmec class A, ccr type 1) was detected in both isolates.

Implications:

  • This study provides the first whole genome sequences of opportunistic S. cohnii from human patients.
  • The findings contribute to understanding the genetic basis of S. cohnii pathogenicity and antibiotic resistance.
  • Insights into SCCmec elements can inform strategies against Staphylococcal infections.

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.

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 DNA in Prokaryotes00:46

Genomic DNA in Prokaryotes

The genome of most prokaryotic organisms consists of double-stranded DNA organized into one circular chromosome in a region of cytoplasm called the nucleoid. The chromosome is tightly wound, or supercoiled, for efficient storage. Prokaryotes also contain other circular pieces of DNA called plasmids. These plasmids are smaller than the chromosome and often carry genes that confer adaptive functions, such as antibiotic resistance.

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.

Sanger Sequencing

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...
