Enterobacter sepsis is commonly recognized as hospital-acquired infect
ion in childhood. In a five year prospective surveillance of neonatal
sepsis at the Aga Khan University Hospital in Karachi, we identified E
nterobacter sepsis in 28/292 (10%) cases, with an incidence of 0.7 per
thousand births among inborn infants. There was no significant differ
ence in predisposing factors and clinical features between Enterobacte
r and other infections. Approximately half (47%) of Enterobacter infec
tions presented within 72 h of birth and the associated mortality was
21%. Increasing resistance to commonly used first- and second-line ant
ibiotics over the last five years was noted. Enterobacter infections a
re emerging as significant pathogens among cases of neonatal sepsis in
Karachi.
