Methicillin-Resistant Staphylococcus Aureus (MRSA)
Gram-positive bacteria, including MRSA, are the cause of several infections in various body parts. MRSA is brought on by staph infections, which are challenging to treat because they are resistant to some medications. Staphylococcus aureus has genetically developed into MRSA, which has become resistant to a variety of antibiotics, including penicillin and its derivatives, as well as cephems. Either horizontal gene transfer or natural selection may have contributed to the development of this resistance. The structure of MRSA, its virulence traits, the mechanism generating antibiotic resistance, laboratory techniques to distinguish MRSA from MSSA, and variables influencing MRSA's genetic diversity will all be discussed in this paper.
Structure of MRSA and Its Virulence Factors
Gram-positive Staphylococcus aureus, a member of the Micrococcaceae family, is frequently seen in various unusual forms that resemble grapes. This bacteria can be found single, in pairs, or in tetrads. Beta-lactam antibiotic resistance is a common way to identify MRSA (Foster 26). MRSA is resistant to a variety of antibiotics, including methicillin, semi-synthetic penicillin
