Abstract

 Introduction Neonatal mortality rate is regarded as one of the indicators for measuring the health status of a nation. Septicaemia continues to be a major cause of neonatal mortality and morbidity worldwide. At present, in the developing countries, gram negative bacilli remain the major cause of neonatal septicaemia. These organisms have developed multi-drug resistance over the last two decades. The knowledge about these factors is limited, hence the current study was done to study these pathogens and antibiotic resistance pattern in them. Materials and methods A retrospective study of 210 neonates(less than 30 days of age and with septecaemia), using microbiology culture report of neonatal septicaemia cases from 2008 to August 2011,was undertaken in Department of Microbiology, Kasturba Medical College, Mangalore. It was a proforma based study. Microbiological details with regards to blood culture reports and antibiotic susceptibility profile were obtained from the laboratory records. Results In the present study, out of 210 bacterial isolates, majority of the isolates causing neonatal septicaemia are Staphylococcus aureus followedby Acitenobacter spp, Klebsiella pneumonia, Pseudomonas aeruginosa, Escherichia coli, Enterobacterspp., Streptococcus viridians group, Staphylococcus epidermidis, Citrobacter spp., Enterococcus spp, Proteus spp and Klebsiellaoxytoca. Maximum resistance among the isolated organisms was seen against amoxycillin/ ampicillin. The resistance level to third-generation cephalosporins—cefotaxime, ceftriaxone and ceftazidime was also high, indicating that the use of these drugs alone may be ineffective. About 5.7% strains were Methicillin Resistant S.aureus(MRSA). . The high level of resistance could be due to extended spectrum â lactamases expression in bacteria. Resistance levels were higher in acitenobacter spp. and K.pneumoniae. Conclusion The bacteriological profile of neonatal septicaemia is constantly under change with advances in early diagnosis and treatment. Therefore, continued surveillance for various pathogens and their susceptibility profile should be done to effectively and timely treat the patients of neonatal septicaemia.
