Bacteriophages can be used effectively to cure bacterial infections. They are known to be active against bacteria but inactive against eukaryotic cells. Nevertheless, novel observations suggest that phages are not neutral for higher organisms. They can affect physiological and immunological processes which may be crucial to their expected positive effects(More)
Bacteriophages are among the most numerous creatures on earth and they are omnipresent. They are thus in constant natural contact with humans and animals. However, the clinical and technological use of bacteriophages has also become more frequent, which is why all aspects of phage–mammal interactions need to be explored. Bacteriophages are able to interact(More)
Bacteriophages constitute a serious alternative to antibiotic therapy of bacterial infections. They are also extremely numerous entities: phages can be found in almost all places on Earth and are constantly present in human and animal bodies. Observations of the effect of therapeutic staphylococcal phages and their bacterial hosts on melanoma migration in(More)
Bacteriophages are viruses that infect bacteria. It was shown that bacteriophage therapy is an effective method of combating bacterial infections, including infections caused by antibiotic-resistant bacterial strains. One of the main obstacles to widespread use of phage preparations is limited knowledge regarding the influence of bacteriophages on human(More)
BACKGROUND Bacteriophage therapy is considered one of the most attractive alternatives to antibiotic treatment, which may be significant due to the rising number of antibiotic-resistant bacterial strains. Patients with cancer frequently suffer bacterial infections resulting from immunosuppression caused by anticancer treatment; thus they constitute a(More)
The antibacterial activity of bacteriophages has been described rather well. However, knowledge about the direct interactions of bacteriophages with mammalian organisms and their other, i.e. non-antibacterial, activities in mammalian systems is quite scarce. It must be emphasised that bacteriophages are natural parasites of bacteria, which in turn are(More)
Extended-spectrum β-lactamases (ESBLs) and AmpC β-lactamases are plasmid (but also chromosomally) encoded enzymes found in Enterobacteriaceae, determining resistance to a variety of important antibiotics including penicillins, cephalosporins, and monobactams. In recent decades, the prevalence of ESBL/AmpC-producing bacteria has increased rapidly across the(More)
