Evaluation of lytic activity of staphylococcal bacteriophage Sb-1 against freshly isolated clinical pathogens.

In recent decades the increase in antibiotic-resistant bacterial strains has become a serious threat to the treatment of infectious diseases. Drug resistance of Staphylococcus aureus has become a major problem in hospitals of many countries, including developed ones. Today the interest in alternative remedies to antibiotics, including bacteriophage treatment, is gaining new ground.

Bacteriophages as potential new therapeutics to replace or supplement antibiotics.

Over recent decades, a growing body of literature has validated the use of bacteriophages for therapy and prophylaxis in the war against drug-resistant bacteria. Today, much more is known about bacteriophages than in the 1930s when phage therapy first appeared and began to spread to many countries. With rapid dissemination of multi-drug-resistant bacterial pathogens, the interest in alternative remedies to antibiotics, including bacteriophage treatments, is gaining new ground.

Mobile regulatory cassettes mediate modular shuffling in T4-type phage genomes.

Coliphage phi1, which was isolated for phage therapy in the Republic of Georgia, is closely related to the T-like myovirus RB49. The approximately 275 open reading frames encoded by each phage have an average level of amino acid identity of 95.8%.
