The common pathogen frequently responsible for nosocomial infections in the nursery unit is Escherichia coli. This bacterium is part of the normal flora of the gastrointestinal tract but can become pathogenic, especially in vulnerable populations such as newborns. In a hospital setting, particularly in a nursery, the risk of infection increases due to the presence of invasive procedures, the immature immune systems of neonates, and the potential for cross-contamination between patients.

Nosocomial infections in neonatal units can arise from E. coli when it is transmitted via the hands of healthcare workers or through contaminated equipment, posing a serious risk to infants who may already be dealing with congenital health issues or other complications. The ability of E. coli to produce virulence factors, such as endotoxins, can further exacerbate infections in these sensitive populations.

While Candida albicans can cause fungal infections and is relevant in certain contexts, it is less commonly associated specifically with the nursery unit compared to E. coli. Clostridium difficile is more known for causing infection in older patients, particularly after antibiotic use, and Mycobacterium tuberculosis poses a risk in respiratory contexts, making them less relevant to the nursery unit's primary concerns for nosocomial infections.
