Abstract

Elucidation of antibiotic resistance correlation with manifestation of the pathogenic properties and aggressiveness in particular is of definite importance. Because of a wide spread of antibiotic resistance among staphylococci and ever increasing in pathology the role of S. epidermidis, the changes in penetration of the internal organ tissues, activity and intensity of capture and digestion by phagocytes of S. epidermidis mutants D-5/240 carrying the chromosome markers of penicillin and erythromycin resistance were analyzed. It was shown that the chromosome markers of the antibiotic resistance in staphylococci promoted their more active penetration into the tissues of the internal organs, affected permeability of the cell membranes, changed the activity of the digestion enzymes in the phagocyting cells (lowering the number of the acid phosphatase), prevented phagocytosis completeness and decreased the microorganism immunogenic properties.

CRISPR & Staphylococcus

CRISPR-Cas system enables the editing of genes to create or correct mutations. Staphylococci are associated with life-threatening infections in hospitals, as well as the community. Here is the latest research on how CRISPR-Cas system can be used for treatment of Staphylococcal infections.

Allergy & Infectious Diseases

Allergies result from the hyperreactivity of the immune system to some environmental substance and can be life-threatening. Infectious diseases are caused by organisms including bacteria, viruses, fungi and parasites. They can be transmitted different ways, such as person-to-person. Here is the latest research on allergy and infectious diseases.

Antimicrobial Resistance (ASM)

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.
