Abstract

Background Neonatal septicemia constitutes an important cause
of morbidity and mortality among neonates in Indonesia. The ex-
cessive use of antibiotics may cause antibiotic resistant bacteria
and may cause neonatal fungal infection.
Objective To investigate the spectrum of organisms which cause
neonatal sepsis and assess their sensitivity to various groups of
drugs in the neonatal unit.
Methods A prospective study conducted on newborn babies de-
livered in Cipto Mangunkusumo Hospital, Jakarta from July 2004-
May 2005 who presented clinical signs of septicemia were sub-
jected for blood culture. Those sensitive to antibiotics for 7 days
yet showed no clinical improvement were also cultured for fungi.
Results A total of 499 blood cultures were taken, 320 were posi-
tive for bacteria (positivity rate was 65.3%). There were 192 samples
cultured for fungi, and the positivity rate was 64% (all for Candida
sp). Acinetobacter calcoaceticus was the most common bacteria
found (35.7%), followed by Enterobacter sp (7.0%), and Staphylo-
coccus sp (6.8%). Most bacteria showed high degrees of resis-
tance to commonly used antibiotics (ampicillin and gentamicin).
There were also high degrees of resistance to cephalosporins by
both Gram negative and Gram positive organisms. Only 61.7% of
A. calcoaceticus, and 45.7% of Enterobacter sp were sensitive to
ceftazidime. Gram negative organisms were also highly resistant
to amikacin, but Staphylococcus sp was only moderately resis-
tant. Resistance to carbapenem (meropenem and imipenem) var-
ied from moderate to low. Drugs which were not used for newborn
babies (quinolones/ciprofloxacin and chloramphenicol) varied from
moderate to high resistance.
Conclusion Neonatal sepsis remains one of the major causes of
mortality in our neonatal unit. Most organisms have developed
multidrug resistance, and management of patients infected with
these organisms and especially those with fungi infection are be-
coming a problem in developing countries
