Acinetobacter junii caused sepsis in preterm infants. Contaminated intravenous fat emulsion was the likely source, highlighting the need for aseptic preparation of neonatal nutrition.
Area of Science:
- Neonatal Medicine
- Infectious Diseases
- Microbiology
Background:
- Acinetobacter junii outbreaks can occur in neonatal intensive care units.
- Preterm infants are particularly vulnerable to severe infections.
Purpose of the Study:
- To investigate a sudden outbreak of Acinetobacter junii sepsis in preterm infants.
- To identify the source and risk factors associated with the infection.
Main Methods:
- Clinical case review of six affected preterm infants.
- Microbiological analysis of blood cultures.
- In vitro susceptibility testing of Acinetobacter junii to various intravenous nutritional products.
Main Results:
- Six preterm infants developed Acinetobacter junii sepsis within 48 hours.
- Intravenous fat emulsion (Intralipid 10%) supported excellent growth of the outbreak strain.
- Other nutritional solutions did not support significant growth, and no common batch contamination was identified.
Conclusions:
- Acinetobacter junii can cause life-threatening sepsis in preterm neonates.
- Contaminated intravenous fat emulsion is a potential source of infection.
- Aseptic preparation of intravenous feedings is crucial for infection control in neonatal units.
