Multidrug Resistant Nosocomial Infections Essay

A Promising Strategy Against Multidrug-Resistant Nosocomial Infections

1. Public health experts have defined certain environments and specific pathogens for which alternatives to antibiotics will be particularly crucial.

0. What is a nosocomial infection? What is one reason why nosocomial infections are particularly difficult to treat? (4 pts)

A nosocomial infection is an infection acquired by a patient during a hospital stay or while receiving care in another healthcare facility (Blot et al., 2022). These infections are particularly difficult to treat because hospitalized patients are often immunocompromised, and the pathogens involved are frequently multidrug resistant.

0. What are ESKAPE pathogens, generally speaking? Which six bacterial species make up the ESKAPE pathogens? (4 pts)

ESKAPE pathogens are a group of bacteria that are known for escaping the effects of conventional antibiotics. They are responsible for many hospital-acquired infections and significantly contribute to antibiotic resistance.

The six bacterial species that make up the ESKAPE pathogens are:

i. Enterococcus faecium

ii. Staphylococcus aureus

iii. Klebsiella pneumoniae

iv. Acinetobacter baumannii

v. Pseudomonas aeruginosa

vi. Enterobacter species

1. Answer the following questions to learn more about phage therapy.

1. Broadly, what is the goal of phage therapy? (4 pts)

The primary goal of phage therapy is to use...

What are lytic phages? Why are lytic phages (as opposed to other types of phages) required for phage therapy? (6 pts)

Lytic phages are bacteriophages that infect bacterial cells, rapidly replicate within them, and then cause cell lysis to...

…(4 pts)

A phage cocktail is used to broaden the range of targeted bacteria. By combining multiple phages, the treatment can cover a broader spectrum of bacterial strains and reduce the chance of bacteria developing resistance against a single phage type (Akram et al., 2023).

1. Phage therapy is not likely to be a replacement for antibiotics, but there are indications that the two therapies can be used synergistically to combat MDR infections. What does the term synergism mean in relation to drugs and therapeutics? (4 pts)

Synergism refers to the phenomenon where the combined effect of two treatments is greater than the sum of their individual effects. For example, when phage therapy and antibiotics are used together, they may work more effectively to eliminate multidrug-resistant bacteria than either treatment…

Nurse burnout is a common occurrence. This can exacerbate an ongoing problem that is seen in hospitals, nosocomial infections. Nosocomial infections remain prevalent for patients with extended hospital stays like those in intensive care units. An infection that starts roughly 48 hours after admission, those in intensive care units (ICUs) experience a continued rate of infection leading to increase length of stay, mortality, and morbidity. The number of patients that

Problem From the onset, it is important to note that nosocomial or healthcare-acquired infections (HAIs) happen to be rather common in our healthcare settings. In basic terms, nosocomial infections could be defined as the all those infections that are acquired or contracted within the healthcare environment. To be more specific, the World Health Organization – WHO (2020) defines the said infections as all those infections that “affect patients in a hospital
