Factors Affecting Phage-Bacteria Coevolution Dynamics.

Bacteriophages (phages) have coevolved with their bacterial hosts for billions of years. With the rise of antibiotic resistance, the significance of using phages in therapy is increasing. Investigating the dynamics of phage evolution can provide valuable insights for pre-adapting phages to more challenging clones of their hosts that may arise during treatment.

Phage vB_KlebPS_265 Active Against Resistant/MDR and Hypermucoid K2 Strains of .

is an important opportunistic pathogen often resistant to antibiotics. Specific phages can be useful in eliminating infection caused by . phage vB_KlebPS_265 (KlebP_265) and its host strain were isolated from the sputum of a patient with infection.

Genome Analysis of Anti-Phage Defense Systems and Defense Islands in : Preservation and Variability.

Anti-phage defense systems are widespread in bacteria due to the latter continuous adaptation to infection by bacteriophages (phages). has a high degree of intrinsic antibiotic resistance, which makes phage therapy relevant for the treatment of infections caused by this species. Studying the array of anti-phage defense systems that could be found in helps in better adapting the phages to the systems present in the pathogenic bacteria.

Complete genome sequence of a rare recombinant GII.5[P16] norovirus found in Russian Siberia.

Noroviruses (family Caliciviridae) are common causes of acute gastroenteritis worldwide. Multiple polymerase/capsid combinations have been identified among members of norovirus genogroup GII, at least 10 of which contain GII.P16 polymerase.

The First Phage vB_PseuGesM_254 Active against Proteolytic Strains.

Bacteria of the genus, including the subgroup, play an important role in the environmental microbial communities. Psychrotolerant isolates of can produce thermostable proteases and lipases. When contaminating refrigerated raw milk, these bacteria spoil it by producing enzymes resistant to pasteurization.
