Cluster EA Bacteriophages: Phylogenomic Relationships and Host Range Predictions.

Bacteriophages are being widely harnessed as an alternative to antibiotics due to the global emergence of drug-resistant pathogens. To guide the usage of these bactericidal agents, characterization of their host specificity is vital-however, host range information remains limited for many bacteriophages. This is particularly the case for bacteriophages infecting the genus, despite their importance in agriculture, biomedicine, and biotechnology.

Complete Genome Sequence of the Bacteriophage Chako.

We characterized the complete genome sequence of Chako, an obligate lytic bacteriophage with siphovirus morphology from subcluster EA1 that infects Microbacterium foliorum NRRL B-24224. Its 41.6-kb genome contains 62 putative protein-coding genes and is highly similar to that of bacteriophage HanSolo (99.

Comparative Genomics of Closely-Related Cluster DR Bacteriophages.

Bacteriophages infecting bacteria of the genus have increasingly gained interest in the scientific community for their diverse applications in agriculture, biotechnology, and medicine, ranging from biocontrol agents in wastewater management to the treatment of opportunistic pathogens in pulmonary disease patients. However, due to the time and costs associated with experimental isolation and cultivation, host ranges for many bacteriophages remain poorly characterized, hindering a more efficient usage of bacteriophages in these areas. Here, we perform a series of computational genomic inferences to predict the putative host ranges of all cluster DR bacteriophages known to date.

Complete Genome Sequence of the Bacteriophage BiggityBass.

Here, we characterized the complete genome of the BiggityBass, a lytic subcluster DR bacteriophage infecting Gordonia terrae CAG3. Its 63.2-kb genome contains 84 protein-coding genes, of which 40 could be assigned a putative function.
