ABSTRACT
BACKGROUND: Neonatal sepsis is the most common cause of mortality and morbidity. It is a major global public health challenge, particularly in developing countries. Therefore, knowing the current status of bacterial isolates and their antimicrobial resistance profile is essential to physicians and health workers to implement appropriate intervention. The aims of this study was to assess a ten-year trend of bacterial prevalence isolates from blood culture among neonates (<1 month of age). METHOD: A hospital-based retrospective study was conducted on 1854 neonatal patients who were admitted at University of Gondar Specialized Comprehensive Hospital between 2010 and 2020. Sociodemographical and laboratory data were collected from medical records. Quality of the data was assured through standard operational procedures. Data were entered and analysed using SPSS version 20. Bivariate analysis was employed to determine strings of association between the outcome variable and sociodemographic variables. A P value less than 0.05 will be considered to be statically significant. RESULTS: In a total of 1854 patients, 538 (29%) were culture positive. The overall neonatal sepsis infection rate was 287 (53.5%) for male and 249 (46.5%) for female. The highest proportion of neonatal sepsis infection rate was observed among the patients in the age range between 3 and 28 days and gestational at birth <37 weeks, 461(86%) and 278 (52%), respectively. Gestational at birth (P ≤ 0.001, AOR = 5.81, CI: 4.63-7.29) is significantly associated with bacterial isolates. The predominant pathogens were Staphylococcus aureus, 18 (76.6%), Klebsiella pneumoniae, 146 (38%), and E. coli, 45 (11.7%) among the age range less than one weak. Klebsiella spp, S. aureus, and E. coli showed a high level of resistance to most tested antimicrobials. Amikacin, ciprofloxacin and norfloxacin, and erythromycin were the most effective antibiotics whereas ampicillin, amoxicillin, and cotrimoxazole were the least effective antibiotics for isolates. CONCLUSION: Neonatal sepsis infection is common in the 3-28 days of age range. S. aureus, E. coli, and K. pneumonia were the most common isolates. Most the bacterial pathogens were resistant to commonly prescribed antibiotics. Therefore, an antimicrobial sensitivity test for bacterial isolates is recommended to provide updated data for the physician in choosing the appropriate antibiotic for better patient treatment outcome.
