To tell:
Why do patients with methicillin-resistant Staphylococcus aureus (MRSA) as part of their normal microbiota pose a risk to other patients in a hospital?
Introduction:
The upper respiratory region is most prone to infection because of the low temperature. The nose has the cooler region of the respiratory system so that most of the microbes present in the nose. Staphylococcus aureus grows in the nasal cavity which is a gram-positive bacteria and it is an opportunistic pathogen.
Explanation of Solution
Methicillin-resistant Staphylococcus aureus (MRSA) is commonly known as antibiotic resistance. Antibiotics are useful in treating the microbial diseases. Antibiotic resistance means it has some changes in the bacteria that gain resistant to the microbial action.
MRSA is usually acquired from the hospital so it is referred to as hospital-associated or nosocomial infections. Methicillin resistance is resistance to the β-lactam antibiotics by a change in a single genetic element. The β-lactam antibiotics are cephalosporin, penicillin, and carbapenems.
This strain mostly occurs in the UK to the patients who are admitted to the hospital over a month. It does not need any treatment because it does not cause harmful effects. It does not infect a single person, the complete community is affected by this MRSA. MRSA is mostly existed as normal microbes because of the absence of any serious effects, although it infects the other peoples in a hospital.
The MRSA is an antibiotic-resistant bacteria that can infect the health care patients but it exists as a normal microbe is explained.
