Pattern of Microbial Growth and Antibiotic Sensitivity on Blood Culture among Neonates at a Tertiary Care Hospital.
Pak Paed J Jan ;38(2):75-8.

Objective: To study the pattern of bacterial isolates in neonatal septicemia along with their antibiotic susceptibility pattern. Study design: Observational Study. Place and duration of Study: Neonatology Unit, Department of Pediatrics, Sir Ganga Ram Hospital, Lahore, from September 2012 to September 2013. Material and methods : All neonates with early or late onset septicemia were included in the study. Blood cultures were done for all of these patients to identify the pathogens involved which were then tested for susceptibility to commonly used antimicrobials. Results: One hundred (100) neonates with septicemia were included in the study. 71 % of these were male while 29 % were female. Among bacterial isolates, Gram negative organisms were predominant (74%) while gram positive organisms were 24 % and Candida was found in 2 % cases. Among the Gram negative bacteria, Citrobacter was the commonest (61%) while Staphylococcus aureus was the commonest gram positive isolate (100%). Gram negative isolates were most commonly susceptible to Imipenem/meropenem (34 %) while the gram positive isolates were most susceptible to vancomycin (100 %) Conclusion: Local antimicrobial susceptibility patterns could help in deciding empiric therapy for septicemia due to gram negative or gram positive isolates.
