Bacterial Transformation

55.1K
In 1928, bacteriologist Frederick Griffith worked on a vaccine for pneumonia, which is caused by Streptococcus pneumoniae bacteria. Griffith studied two pneumonia strains in mice: one pathogenic and one non-pathogenic. Only the pathogenic strain killed host mice.
Griffith made an unexpected discovery when he killed the pathogenic strain and mixed its remains with the live, non-pathogenic strain. Not only did the mixture kill host mice, but it also contained living pathogenic bacteria that...

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.

Area of Science:

  • Environmental microbiology
  • Public health
  • Wastewater treatment

Background:

  • Antimicrobial resistance (AMR) poses a significant global health threat.
  • Antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB) are key components of AMR.
  • Anaerobic digestion (AD) is a process used for waste treatment and energy recovery.

Purpose of the Study:

  • To review the current understanding of ARGs and ARB removal during AD.
  • To identify challenges in detecting and quantifying ARGs in AD systems.
  • To explore future research directions for enhancing ARG elimination via AD.

Main Methods:

  • Literature review of existing studies on ARGs and AD.
  • Analysis of current detection and quantification methods for ARGs.
Horizontal gene transfer (HGT)
Mobile genetic elements (MGEs)
  • Discussion of risk assessment and co-exposure effects of ARGs.

    • Main Results:

    • AD shows potential for ARG and ARB removal, contributing to AMR mitigation.
    • Current methods for ARG detection and quantification in AD require improvement for reliability.
    • Unresolved challenges include risk assessment, co-exposure impacts, and standardization of studies.

    Conclusions:

    • AD is a promising technology for controlling ARGs and ARB.
    • Standardized methods and further research are essential for effective ARG management in AD.
    • Addressing knowledge gaps will enable optimized AD strategies for ARG elimination.
