The rise of multi-drug-resistant (MDR) bacteria has spurred renewed interest in the use of bacteriophages in therapy. However, mechanisms contributing to phage-mediated bacterial clearance in an animal host remain unclear. We investigated the effects of host immunity on the efficacy of phage therapy for acute pneumonia caused by MDR Pseudomonas aeruginosa in a mouse model. Comparing efficacies of...
Viruses are ubiquitous and can infect any of the three existing cellular lineages (Archaea, Bacteria and Eukarya). Despite the persisting negative public perception of these entities, scientists learnt how to domesticate some of them. The study of molecular mechanisms essential to the completion of viral cycles has greatly contributed to deciphering fundamental processes in biology. Nowadays, viruses...
In this study, we describe the characterization, cloning, expression and purification of the lysin A gene of the mycobacteriophage TM4. The gene TM4_gp29 (gp29) is a 1644‐bp gene that codes for a 58.6‐kDa protein and contains peptidoglycan recognition protein, Zn‐binding and amidase catalytic domains. The gene was cloned into Escherichia coli using the ‘His‐Tag’ pQE60 vector. After affinity chromatography‐mediated...
Ardmore is a novel mycobacteriophage isolated from a soil sample collected in County Waterford, Ireland. The genome of this phage has been fully sequenced and is composed of 52,141 bp of linear double stranded DNA with a GC content of 61.49%. 88 ORFs were identified of which 34 were assigned predicted functions based on their homology to previously characterised proteins, their location in the genome,...
