MRSA is responsible for several difficult-to-treat infections in humans. It caused more than 100,000 deaths worldwide attributable to antimicrobial resistance in 2019. MRSA is any strain of S. aureus that has developed (through natural selection) or acquired (through horizontal gene transfer) a multiple drug resistance to beta-lactam antibiotics.
An estimated 21% to 30% of the human population are long-term carriers of S. aureus, [2] [3] which can be found as part of the normal skin microbiota, in the nostrils, [2] [4] and as a normal inhabitant of the lower reproductive tract of females.
Spiral bacteria are another major bacterial cell morphology. [2] [30] [31] [32] Spiral bacteria can be sub-classified as spirilla, spirochetes, or vibrios based on the number of twists per cell, cell thickness, cell flexibility, and motility. [33] Bacteria are known to evolve specific traits to survive in their ideal environment. [34]
Boils – Boils are the most common type of staph infection, they are pockets of white pus that start where a hair follicle or oil gland is. The boil is tender and red where the infection is located on the skin. Impetigo – Impetigo is most prominent among children, and is usually located around their mouth, nose, hands, and feet. It shows up ...
A boil, also called a furuncle, is a deep folliculitis, which is an infection of the hair follicle. It is most commonly caused by infection by the bacterium Staphylococcus aureus , resulting in a painful swollen area on the skin caused by an accumulation of pus and dead tissue. [ 1 ]
A carbuncle is a cluster of several boils, which is typically filled with purulent exudate (dead neutrophils, phagocytized bacteria, and other cellular components). [5] Fluid may drain freely from the carbuncle, or intervention involving an incision and drainage procedure may be needed. [ 4 ]
Because it can be found in virtually all CA-MRSA strains that cause soft-tissue infections, it was long described as a key virulence factor, allowing the bacteria to target and kill specific white blood cells known as neutrophils. This view was challenged, however, when it was shown that removal of PVL from the two major epidemic CA-MRSA ...
Persister cells have entered a non-growing, or extremely slow-growing physiological state which makes them tolerant (insensitive or refractory) to the action of antimicrobials. When such persisting pathogenic microbes cannot be eliminated by the immune system, they become a reservoir from which recurrence of infection will develop. [ 10 ]
