Isolation of a PRD1-like phage uncovers the carriage of three putative conjugative plasmids in clinical Burkholderia contaminans.

The Burkholderia cepacia complex (Bcc) is a group of increasingly multi-drug resistant opportunistic bacteria. This resistance is driven through a combination of intrinsic factors and the carriage of a broad range of conjugative plasmids harbouring virulence determinants. Therefore, novel treatments are required to treat and prevent further spread of these virulence determinants.

Complex interactions between diverse mobile genetic elements drive the evolution of metal-resistant bacterial genomes.

In this study, we compared the genomes of three metal-resistant bacteria isolated from mercury-contaminated soil. We identified diverse and novel MGEs with evidence of multiple LGT events shaping their genomic structure and heavy metal resistance. Among the three metal-resistant strains, Sphingobium sp SA2 and Sphingopyxis sp SE2 were resistant to multiple metals including mercury, cadmium, copper, zinc and lead.

Objectives: Providencia is a genus of gram-negative bacteria within the order Enterobacterales, closely related to Proteus and Morganella. While ubiquitous in the environment, some species of Providencia, such as P. rettgeri and P.

Nonsense-mediated decay machinery in is inefficient and non-essential.

Nonsense-mediated decay (NMD) is a conserved mRNA quality control process that eliminates transcripts bearing a premature termination codon. In addition to its role in removing erroneous transcripts, NMD is involved in post-transcriptional regulation of gene expression via programmed intron retention in metazoans. The apicomplexan parasite shows relatively high levels of intron retention, but it is unclear whether these variant transcripts are functional targets of NMD.

Burkholderia contaminans Bacteriophage CSP3 Requires O-Antigen Polysaccharides for Infection.

The Burkholderia cepacia complex is a group of opportunistic pathogens that cause both severe acute and chronic respiratory infections. Due to their large genomes containing multiple intrinsic and acquired antimicrobial resistance mechanisms, treatment is often difficult and prolonged. One alternative to traditional antibiotics for treatment of bacterial infections is bacteriophages.
