Pseudomonas putida septicemia in a special care nursery due to contaminated flush solutions prepared in a hospital pharmacy.

چکیده
Pseudomonas putida bloodstream infections were reported in two preterm neonates from a special care nursery. An unopened container of preservative-free heparin flush, compounded several weeks earlier in the hospital pharmacy and from the same batch that was administered to the patients, grew P. putida with a pulsed-field gel electrophoresis (PFGE) pattern identical to that of the patients' isolates. Intrinsic contamination was ruled out by the absence of similar reports from other hospitals and by sterility testing of unopened stock solutions. We investigated the in vitro persistence of P. putida in heparinized saline: even under refrigerated conditions, inocula of 10(2) and 10(3) CFU/ml exhibited growth at 21 and 35 days, respectively. These findings highlight the need for compliance with current standards of aseptic technique and quality assurance during the preparation of compounded sterile products.
