MICROBIOLO D311 WGU Task 1: Essay 2025 Update with complete solution
Bacterial Disease: MRSA
Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial infection that poses
significant challenges to both healthcare professionals and the public. This essay explores MRSA
by examining its causative organism, transmission, symptoms, treatment options, and its impact
on communities. It also provides advice on managing and preventing MRSA infections based on
research findings.
The Organism Behind MRSA
MRSA is caused by Staphylococcus aureus, a type of bacteria that commonly resides on the skin
or in the nose of healthy individuals. While it is usually harmless, certain strains of S. aureus
develop resistance to methicillin, an antibiotic typically used to treat staph infections. This
resistance makes MRSA more difficult to treat and a concern in healthcare settings, where the
bacteria can cause more severe infections. According to the Centers for Disease Control and
Prevention (CDC), MRSA is now resistant to several antibiotics, requiring alternative treatments
(CDC, 2024).
Transmission of MRSA
MRSA is primarily transmitted through direct contact with infected individuals or contaminated
objects. It spreads through skin-to-skin contact or by touching personal items like towels,
clothing, or gym equipment that have been contaminated. Although S. aureus is often harmless
when it resides on the skin, it can cause infections if it enters the body through cuts, abrasions, or
other breaks in the skin (CDC, 2024). Therefore, practicing good hygiene and avoiding sharing
personal items is essential to preventing the spread of MRSA.
Symptoms of MRSA Infection
The symptoms of MRSA can vary depending on the area of the body infected. When affecting
the skin, common signs include redness, swelling, pain, warmth, and pus or other drainage. In
some cases, a fever may also accompany these symptoms. Due to their similarity to symptoms of
insect bites or other skin conditions, laboratory testing is necessary to confirm a MRSA infection
(CDC, 2024). Left untreated, MRSA can lead to more serious complications, such as
bloodstream infections, pneumonia, or infections in surgical wounds.
Treatment Options for MRSA
MRSA infections are treated with antibiotics, but because MRSA is resistant to methicillin,
alternative medications must be used. Common antibiotics for MRSA include vancomycin,
clindamycin, and trimethoprim-sulfamethoxazole. It is crucial for patients to complete the full
course of antibiotics as prescribed to prevent the development of further resistance. In certain
cases, draining infected areas may be necessary to aid in the healing process (CDC, 2024).
Without timely and proper treatment, MRSA infections can become more severe and harder to
manage.
Why I Chose to Research MRSA
, I chose to research MRSA because it is a common infection I have encountered in my role as a
student nurse intern on a medical/surgical unit. It is one of the most frequent bacterial infections I
have seen, and I have observed firsthand how challenging it can be to treat. The increasing
resistance of MRSA to common antibiotics further complicates its management, which sparked
my interest in learning more about the infection and its public health implications.
MRSA’s Impact on Communities
Certain populations are more vulnerable to MRSA infections due to socioeconomic and
healthcare access factors. For example, rural black communities have been found to experience
higher rates of MRSA, likely due to factors such as overcrowded living conditions and limited
access to healthcare (National Library of Medicine, 2024). These factors contribute to delayed
diagnoses and inadequate treatment, which increases the risk of complications. Addressing these
disparities is essential in reducing MRSA’s impact on these communities.
Advice for Those Infected with MRSA
For individuals infected with MRSA, it is important to seek medical attention as soon as
possible. Early treatment can prevent the infection from worsening. In addition, patients should
practice good hygiene to prevent spreading the infection. This includes cleaning the infected
area, keeping it covered, and washing hands frequently. It is also important to inform healthcare
providers about the onset of symptoms and any changes in the infection, as this information
helps guide treatment (CDC, 2024).
Preventing MRSA Infections
Prevention of MRSA relies on maintaining good hygiene and properly caring for any open
wounds or cuts. Individuals should wash their hands regularly with soap and water, apply
antibacterial ointment to wounds, and keep them covered with a clean bandage until healed. It is
also important to avoid sharing personal items such as towels and razors, as these can carry the
bacteria. In healthcare settings, proper infection control measures, including the use of gloves
and gowns, when necessary, can help prevent MRSA transmission (CDC, 2024).
Conclusion
MRSA is a serious bacterial infection that continues to affect many individuals, particularly in
healthcare settings and underserved communities. By understanding how MRSA is transmitted,
its symptoms, and the appropriate treatments, individuals and healthcare professionals can
reduce its spread and severity. Prevention through proper hygiene and timely treatment is key to
managing MRSA effectively. My research has emphasized the importance of addressing both
individual and community-level factors to prevent and control this challenging infection.
