Abstract

Insights

Mycobacterium abscessus infections can be treated with mycobacteriophages, but therapies require personalization. Researchers identified diverse prophages in M. abscessus genomes, offering a new source of therapeutic phages.

Area of Science:

  • Microbiology
  • Genomics
  • Bacteriophage Therapy

Background:

  • Mycobacterium species are significant human pathogens.
  • Mycobacteriophages show promise for treating Mycobacterium infections.
  • Phage susceptibility varies among clinical isolates, necessitating personalized phage therapies.

Purpose of the Study:

  • To identify prophage and phage-related genomic regions in sequenced Mycobacterium strains.
  • To explore the diversity of prophages, particularly in Mycobacterium abscessus.
  • To assess the potential of these prophages as a source for novel therapeutic agents.

Main Methods:

  • Bioinformatic analysis of sequenced Mycobacterium genomes.
  • Identification and characterization of prophage and phage-related sequences.
  • Assessment of prophage diversity and abundance.

Main Results:

  • Numerous and diverse prophages were identified across Mycobacterium strains.
  • Mycobacterium abscessus genomes harbor a particularly rich reservoir of prophages.
  • These prophages represent potential candidates for lytic propagation and therapeutic use.

Conclusions:

  • The genomic analysis reveals a substantial pool of novel phages within Mycobacterium genomes.
  • Targeting these prophages can expand the arsenal of mycobacteriophages for clinical applications.
  • Personalized phage therapy strategies can be enhanced by exploring these genomic resources.

DNA Bacteriophages

Bacteriophages, or phages, are viruses that specifically infect bacteria, utilizing their genetic material to hijack host cellular machinery for replication. DNA bacteriophages employ single-stranded DNA (ssDNA) or double-stranded DNA (dsDNA) genomes. These phages exhibit diverse replication strategies and host interactions, influencing their ecological roles and applications in biotechnology and medicine.ssDNA BacteriophagesssDNA phages, with their small genomes, utilize unique strategies to...

Bacterial Phylum Actinobacteria01:30

Bacterial Phylum Actinobacteria

Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...

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.

Bacterial Phylum Tenericutes01:24

Bacterial Phylum Tenericutes

The phylum Tenericutes, which includes the single class Mollicutes, comprises bacteria that lack cell walls. The term "Mollicutes" derives from the Latin word mollis, meaning "soft." These organisms are among the smallest known and are commonly referred to as mycoplasmas due to the prominence of the genus Mycoplasma, which includes well-known human pathogens. Despite their inability to stain gram-positively (a result of their lack of cell walls), mycoplasmas are phylogenetically related to the...

Lysogenic Cycle of Bacteriophages00:43

Lysogenic Cycle of Bacteriophages

In contrast to the lytic cycle, phages infecting bacteria via the lysogenic cycle do not immediately kill their host cell. Instead, they combine their genome with the host genome, allowing the bacteria to replicate the phage DNA along with the bacterial genome. The incorporated copy of the phage genome is called the prophage. Some prophages can re-activate and enter the lytic cycle. This often occurs in response to a perturbation, such as DNA damage, but can also transpire in the absence of...

Bacterial Phylum Proteobacteria

Proteobacteria, one of the largest and most diverse bacterial phyla, encompasses a wide range of Gram-negative bacteria distinguished by their outer membrane composed of lipopolysaccharides. These microorganisms exhibit various metabolic capabilities, including phototrophy, chemolithotrophy, and heterotrophy, and thrive in diverse environments from soil to aquatic systems and host-associated niches. The phylum is divided into six classes: Alphaproteobacteria, Betaproteobacteria,...
