Methicillin-Resistant Staphylococcus Aureus (MRSA)
MRSA entail causative staph infection which is complicated to treat since it is resistant to antibiotics. The bacterium is dangerous because it leads infection to various parts of the body. To understand the Methicillin-Resistant Staphylococcus Aureus (MRSA), an essay has been prepared to analyze its structure and virulence factors in human beings. Similarly, the essay examines mechanisms that cause antimicrobial resistance linked with MRSA and a series of immunological responses, which are mediated in the course of infection in the human host. Various laboratory methods used in differentiating MRSA from MSSA is also discussed. Lastly, the paper analyzes factors that are responsible for the development of genetically diverse MRSA and the risks that are linked with it becoming a hospital-acquired infection.
Structure of MRSA and Virulence Factors in Human Host
MRSA is composed of strain of S-aureus with an established resistance to beta-lactam antibiotics, including penicillin-like cephalosporin (1—3), methicillin, oxacillin, and dicloxacillin. According to Sawada et al. (6563), the bacterium is usually identified as an antibiotic-resistant strain S. aureus which is afflicted in communities and hospitals across the world. It (MRSA) is a gram-positive bacteria in grape-like clusters which are termed cocci. MRSA is facultative bacteria that is responsible for many complexities which are experienced when treating infections.
Throughout the structure, MRSA is a prokaryotic organism (doesn't have a nucleus protecting the genome) and has the presence of small pieces of plasmids (DNA) which exist in bacteria's separate cells. Its structure is crystal violet dye in color, and it is retained by the thick peptidoglycan cell wall in gram-positive organisms. The bacterium also contains strains that are resistant to beta-lactams like cephalosporin, non-beta-lactams, and derivatives. In the human host, the bacterium is identified in athletes, military personnel, school students, and daycare who receives inpatient medical care have medical devices or surgery in the body since they have a
