Complete Genome Sequence of Bacillus thuringiensis Bacteriophage Smudge

Area of Science:

• Microbiology
• Virology
• Genomics

Background:

• Bacteriophages are viruses that infect bacteria and play crucial roles in microbial ecosystems.
• Bacillus thuringiensis is a soil bacterium with agricultural and environmental significance.
• Characterizing novel bacteriophages contributes to understanding phage diversity and host interactions.

Purpose of the Study:

• To perform complete genome sequencing of a newly isolated bacteriophage, named Smudge.
• To classify Smudge within the broader context of Bacillus phages.
• To identify the genetic makeup and potential characteristics of Smudge.

Main Methods:

• Enrichment of bacteriophage from soil using Bacillus thuringiensis DSM-350 as the host.
• Whole-genome sequencing of the isolated bacteriophage Smudge.
• Bioinformatic analysis for gene prediction and phage classification.

Main Results:

• The complete genome of bacteriophage Smudge was successfully sequenced.
• Smudge was identified as a myovirus, a type of bacteriophage with a contractile tail.
• The Smudge genome comprises 292 predicted genes.
• Smudge was classified as belonging to the C1 cluster of Bacillus phages.

Conclusions:

• The genome sequence provides a foundational resource for understanding Smudge's biology and evolution.
• Classification within the C1 cluster suggests potential functional or evolutionary relationships with other Bacillus phages.
• This study expands the genomic database of Bacillus-infecting phages, aiding further research in phage therapy and microbial ecology.
