Nosocomial infections in the neonatal intensive care unit

Abstract

Nosocomial infections are significant causes of morbidity and mortality in patients who require newborn intensive care. The most common bacterial pathogens are Gram-positive bacteria, including Staphylococcus epidermidis, Staphylococcus aureus, and Enterococcus species. Gram-negative enteric bacilli and Gram-negative environmental bacteria are involved in outbreaks and occasional cases of nosocomial infection. The incidence of fungal infection has increased over the past 10 years; fungemia is the most commonly recognized infection. Surveillance for nosocomial infection is essential to identify outbreaks and detect unsuspected reservoirs of pathogens. A variety of molecular techniques can be used to determine the genetic relatedness of pathogens. Prevention of infection requires the identification of contaminated equipment, education regarding infection control methods including hand washing, and the judicious use of antimicrobial agents.
