Separate and combined action of Dimethylsulfoxid (DMSO) and Rimantadin on the reproduction of phages T--3, T--4, T--7 and lambda was studied. The maximum activation of reproduction of phages T--3 and T--7 by DMSO was observed for 6 minutes of latent period. At the same time this compound did not render the action on reproduction phages T--4 and, because they utilize cell RNA-polimerase. It was shown that DMSO stimulated the synthesis of T--3 phage DNA by action on T--3 phage RNA-polymerase. Combined application of both DMSO and Rimantadin eleminated in some degree its reciprocal effect on T--3 phage macromoelecules synthesis and complet eliminated inhibitory action of Rimantidin on infective phage T--3 production.

A phage-antibiotic synergy could be an alternative in urinary tract infection (UTI) therapy, as it leads to the elimination of bacteria and to the reduction in variants resistant to phages and antibiotics. The aims of the in vitro study were to determine whether phages vB_Efa29212_2e and vB_Efa29212_3e interact synergistically with selected antibiotics in the treatment of infections, to optimize antibiotic concentrations and phage titers for the most effective combinations, and to assess their impact on the number of spontaneous resistant variants and on the phages' reproductive cycles. The modified double-layer disc diffusion method, checkboard, time-kill assays, one-step growth method and the double agar overlay plaque assay were implemented.

The impact of antibiotic therapy on the spread of antibiotic resistance genes (ARGs) and its relationship to gut microbiota remains unclear. This study investigated changes in ARGs, mobile genetic elements (MGEs), and gut microbial composition following tilmicosin administration in pigs. Thirty pigs were randomly divided into control (CK), low-concentration (0.

Aims: Stroke is a major public health concern leading to high rates of death and disability worldwide, unfortunately with no effective treatment available for stroke recovery during the repair phase.
Methods: Photothrombotic stroke was induced in mice. Adeno-associated viruses (AAV) were microinjected into the peri-infarct cortex immediately after photothrombotic stroke.

Phages use bacterial host resources to replicate, intrinsically linking phage and host survival. To understand phage dynamics, it is essential to understand phage-host ecology. A key step in this ecology is infection of bacterial hosts.
