75BACTERIOLOGICAL PATTERN AND ANTIBIOTIC SUSCEPTIBILITY IN NEONATOLOGY WARD ULIN GENERAL HOSPITAL, BANJARMASIN, INDONESIAThe prevalence of bacterial profile of blood cultures and their susceptibility patterns in an area, provide guidance to start empirical treatment which is the cornerstone in the management of neonatal sepsis. This present study was aimed at determining the bacteriological profile and their antimicrobial susceptibility patterns in neonatal septicemia cases. About 346 datas were taken from medical record of neonates from 1 July 2011 - 31 December 2012. The bacterial were isolated using API’s method (Analytical Profile Index). Inclusion criteria were neonates with features of sepsis and had positive blood culture. Exclusion criteria, if the data was not complete. The result showed that the most common pathogens were Staphylococcus haemolyticus (15,3 %), followed by Klebsiella pneumoniae (13,3%) and Serratia marcescens(12,1%). Almost all microorganisms have high susceptible to imipenem and low susceptible to Ampicillin and Gentamicin. As the conclusion Staphylococcus haemolyticus is the most frequent gram-positve bacteria causing neonatal sepsisyulia.margareta@ymail.comResearch512015Neonatal sepsis,Bacterial Profile,AntibioticAri Yunanto, Yulia Margareta,Dewi Indah NovianaPratiwiDepartemen of Pediatric, Ulin General Hospital, Banjarmasin, Indonesia.,Departemen of Pediatric, Ulin General Hospital, Banjarmasin, Indonesia.,Departemen of Clinical Pathology, Ulin General Hospital, Banjarmasin, Indonesia
