Objectives: The aim of this study was to analyse occurrence of ESBL [Extended-Spectrum Beta-Lactamases] producing Enterobacteriaceae in patients who were hospitalised in the Depart. of Neonatology Medical University of Gdansk.

Methods: We analysed microbiological records obtained from 2003 to 2007. Strains were identified by classical method and VITEK, VITEK 2 (BioMerieux). Production of ESBL was detected by double disk method.

Results: In the studied period 8632 patients were hospitalised. ESBL+ isolates were recovered from 425 patients. In 2003 ESBL+ isolates were recovered from 216 patients, then 2004 – 48 patients, 2005 – 27 patients, 2006 – 110 patients and 2007 – 24 patients.

The most often isolated was Enterobacter aerogenes from 131 patients (47.1%), then Klebsiella pneumoniae 96 patients (34.5%) Escherichia coli 17 patients (6.1%); Enterobacter cloacae 16 patients (5.8%); Klebsiella oxytoca 11 patients (4%); Citrobacter freundii 6 patients (2.2%) and Enterobacter intermedius 1 patient.

Isolates were recovered from stools and rectal swabs (54%), respiratory tract (37.4%), urine (3.89%) and blood (1.73%).

All strains were susceptible to carbapenems, about 90% to fluoroquinolones and nearly 80% urine isolates to nitrofurantoin, but about 90% isolates were resistant to aminoglicosides and co-trimoxazole.

Conclusions: High percentage of ESBL carriage among children complicates infection control measures and treatment of common infections like urinary tract infection.

Newborns should be screened for ESBL carriage in our setting.
