Which Enterobacteriaceae is primarily associated with nosocomial infections?

• A. Escherichia coli.
• B. Klebsiella pneumoniae.
• C. Salmonella enterica.
• D. Shigella dysenteriae.

Answer: (B)

Klebsiella pneumoniae is primarily associated with nosocomial infections, which are infections acquired in a healthcare setting, such as hospitals. This particular bacterium is known for its ability to cause severe infections, such as pneumonia, bloodstream infections, and urinary tract infections, especially in patients with compromised immune systems or those who have undergone invasive procedures. Its association with nosocomial infections stems from its resilience and its capacity to acquire antibiotic resistance, making it a significant concern in healthcare environments. While other bacteria in the Enterobacteriaceae family can also be involved in hospital-acquired infections, Klebsiella pneumoniae stands out due to its specific prevalence and the severity of the infections it can cause in these settings. This distinguishes it from other options, which may be more commonly associated with community-acquired infections or different disease profiles.
