Methicillin-resistant Staphylococcus aureus is a bacterium causing infections that are difficult to treat in human beings. MRSA is resistant to beta-lactam antibiotics. On the other hand, VRSA is also Staphylococcus aureus that is resistant to glycopeptide antibiotic vancomycin. The underlying health conditions associated with this type of staph infection comprise diabetes, kidney disease, and catheters. The studies by CDC indicate that two in one hundred people carry MRSA, and only one in three people carry staph in their nose, but the organism does not affect them. There is a decline in MRSA infection in the United States where there were about 30, 800 fewer infections between 2005 and 2011. The hospitals also registered about 9,000 deaths of patients between 2005 and 2011. Staphylococcus aureus acquires mobile genetic elements by incorporating plasmids into genomic DNA (Turnidge et al. 176). The acquisition of Staphylococcus aureus resistance to methicillin is through horizontal gene transfer where the coding of mobile genetic elements is not sensitive to beta-lactam inhibition.
Extended spectrum beta-lactamase is an enzyme produced by some bacteria and prevents certain antibiotics from killing the bacteria. It implies that the bacteria become resistant to the antibiotics and only stronger ones can be used in the murder of the bacteria. Extended spectrum beta-lactamase causes infections in people’s blood, lungs, abdomen and urinary tract. The two most important bacteria that car...
