Abstract
Objective: Neonatal sepsis is an infection of the bloodstream in infants younger than 28 days old. It continues to be the major cause of morbidity and mortality among newborns, particularly in middle- and low-income nations. The objective of this study was to isolate and identify aerobic bacteria of neonatal sepsis by blood culture using FAN method followed by subculture and relevant biochemical tests. Methods: It was a cross sectional type of descriptive study where the sample size was 95 and data were collected purposively from the clinically suspected neonatal septicaemia cases from inpatient Pediatric department in Rajshahi Medical College Hospital, Rajshahi. Results: Most 34 (35.79%) of the cases were culture positive, whereas 61 (64%) were culture negative. 7 (21%) of the 34 positive cases were Gram-positive, while 27 (79%) were Gram-negative. S. aureus was found in 6 (17.65%) of the culture-positive isolates, followed by CoNS with 1 (02.94%), E. coli with 14 (41.17%), Klebsiella spp. with 6 (17.65%), P. aeruginosa with 6 (17.65%), and Acinetobacter with 1 (02.94%). Gram-positive bacteria were extremely susceptible to Vancomycin (90%), Gentamicin (90%), and Ciprofloxacin (80%) based on antibacterial susceptibility testing. Colistin (100%) and ampicillin (100%) exhibited the greatest resistance. Meropenem (90%), Amikacin (90%), and Colistin (89%) were the most effective antibiotics against Gram-negative bacteria, whereas Ceftazidime (60%) was the least effective. Vancomycin (100%) and ampicillin (100%) exhibited the highest degree of resistance. Conclusion: Both Gram-positive and Gram-negative aerobic bacteria were related with newborn septicaemia, and a significant proportion of them were resistant to multiple medicines.
