Summary Introduction

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.

Conclusion

The MRSA is an antibiotic-resistant bacteria that can infect the health care patients but it exists as a normal microbe is explained.

Why does Helicobacter pylori cause ulceractions in the lining of the Stomach? 1)The microbes secrete a toxin that prevents the host from detecting invasion of the microbe and thus allows it to thrive in the stomach and damage the host cells. 2)After invasion of the microbe in the cells lining the stomach, they are no longer able to produce mucous to protect the host cells from acid erosion 3)The microbe produces an enzyme that causes the cell to produce potent digestive enzymes that erode the stomach lining. 4)Once the microbe has entered the stomach, it releases digestive enzymes that degrade the mucous secreting cells.

Resistance to antimicrobial agents is more commonly seen in hospital-acquired infections with enteric bacteria than in community-based infections with the same species. Explain why this is so.
