Abstract:
Stenotrophomonas maltophilia is a Gram-negative bacterium associated with multidrug-resistant nosocomial infections, a problem for immunocompromised patients and those with cystic fibrosis. Here, we present the new S. maltophilia-infecting podophage Pokken. Its 76,239-bp genome, with 92 protein-coding genes and 5 tRNA genes predicted, is similar to that of phage N4.
Insights
Researchers discovered Pokken, a novel podophage targeting Stenotrophomonas maltophilia. This bacteriophage offers potential for combating multidrug-resistant infections in vulnerable patients.
Area of Science:
- Microbiology
- Virology
- Genomics
Background:
- Stenotrophomonas maltophilia is a Gram-negative bacterium responsible for multidrug-resistant nosocomial infections.
- These infections pose significant risks to immunocompromised individuals and cystic fibrosis patients.
Purpose of the Study:
- To introduce and characterize a novel bacteriophage, named Pokken, that infects Stenotrophomonas maltophilia.
- To analyze the genomic features of the newly identified podophage.
Main Methods:
- Isolation and characterization of the podophage Pokken from its host bacterium.
- Whole-genome sequencing and bioinformatic analysis of the Pokken genome.
Main Results:
- The genome of podophage Pokken was sequenced, measuring 76,239 base pairs.
- The genome contains predictions for 92 protein-coding genes and 5 tRNA genes.
- Genomic analysis revealed similarities between Pokken and the N4 phage.
Conclusions:
- Podophage Pokken represents a new potential therapeutic agent against Stenotrophomonas maltophilia infections.
- The genomic characteristics of Pokken provide insights into phage-host interactions and phage evolution.
