Aim: The aim of this study was to compare and evaluate the pathogenic bacteria in neo-natal septicemia by using various diagnostic techniques.
Setting and Design: Our study was designed to evaluate a feasible method to diagnose neonatal septicemia even at primary health centre level.
Materials and Methods: Blood samples were collected aseptically from 70 neonates. The specimens were inoculated into brain heart infusion broth and subcultures were performed with specific media. Antibiotic sensitivity pattern of isolates was studied by Modified Kirby Bauer Disc diffusion technique and differentiate the isolates by staining methods. C-reactive protein (CRP) was evaluated by using standard kit method. Results: Out of 70 cases of childhood septicemia of age group 1-30 days, 37 had positive CRP, 36 were positive for BCS and blood culture was positive only in 41 cases, where predominant organism being Klebsiella species (n=28, 68.29%) followed by Escherichia coli (n=4, 9.76%), Pseudomonas aeruginosa (n=3,7.31%), Proteus mirabilis (n=2,4.88%) and Coagulase negative staphylococcus (n=4,9.76%).
Conclusion: Our findings suggest that Klebsiella species as an important cause of neonatal septicemia. The isolated organisms were found to be highly sensitive to cefatoxime and amikacin. Hence, these antibiotics can be considered as the first drug of choice for neonatal septicemia.
