Summary
Nine novel bacteriophages were sequenced from Rhodococcus equi. Six phages are part of the CR cluster, two form the CF cluster, and one is a singleton, expanding the known diversity of actinobacteriophages.
Area of Science:
- Microbiology
- Genomics
- Virology
Background:
- Actinobacteria are a diverse phylum of bacteria, including important human and animal pathogens.
- Bacteriophages (phages) are viruses that infect bacteria and play crucial roles in microbial ecology and evolution.
- Understanding phage diversity is essential for phage therapy and bacterial genomics.
Purpose of the Study:
- To characterize novel bacteriophages isolated from Rhodococcus equi.
- To determine the genomic features and phylogenetic placement of these newly isolated phages.
- To expand the understanding of actinobacteriophage diversity.
Main Methods:
- Isolation and purification of bacteriophages from Rhodococcus equi.
- Genome sequencing and assembly of isolated phages.
- Bioinformatic analysis for genome characterization and phylogenetic analysis.
Main Results:
- Nine complete bacteriophage genomes were successfully sequenced.
- Six phages were assigned to the CR cluster, previously known to contain Gordonia phages.
- Two phages formed a new cluster (CF), and one remained a singleton, with genome sizes ranging from 62,017 to 80,980 bp and GC content between 63.9% and 67.3%.
Conclusions:
- The study significantly expands the known genomic diversity of actinobacteriophages.
- The findings provide new insights into the evolutionary relationships within actinobacteriophage clusters.
- This research contributes valuable genomic resources for further studies in phage biology and potential applications.

70.7K
Bacteriophages, also known as phages, are specialized viruses that infect bacteria. A key characteristic of phages is their distinctive “head-tail” morphology. A phage begins the infection process (i.e., lytic cycle) by attaching to the outside of a bacterial cell. Attachment is accomplished via proteins in the phage tail that bind to specific receptor proteins on the outer surface of the bacterium. The tail injects the phage’s DNA genome into the bacterial cytoplasm. In the...

00:43Lysogenic Cycle of Bacteriophages
62.2K
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...
