RESUMO
BACKGROUND: Meningitis, which is mostly caused by infectious agents, occurs more commonly during the first month of life. Bacterial meningitis is an important source of mortality and morbidity, especially in neonates of resource-limited countries. We aimed to determine the prevalence and etiological agents of bacterial meningitis and their antibiotic susceptibility pattern in neonates at the University of Gondar Comprehensive Specialized Hospital. METHODS: We collected retrospective data from bacteriological results of cerebrospinal fluid of meningitis suspected neonates from 2013 to 2019. Sample collection, culture preparation, bacterial identification, and susceptibility testing were performed using standard microbiological techniques. We extracted data on socio-demographic characteristics and culture and antibiotic susceptibility testing results. We inputted the data using Epi-info version 7 and exported it to SPSS version 20 for analysis. RESULTS: In this study, 1101 cerebrospinal fluid samples, 595 (54%) male and 506 (46%) female neonates, were cultured to look for meningitis-causing bacteria. Of 1101 cerebrospinal fluid, 19 (1.73%) were culture positive for meningitis-causing bacteria. The common etiological agents were Klebsiella pneumoniae 36.8% (7), non-lactose-fermenter Gram-negative rods 21% (4), and Group B streptococcus 15.8% (3). The overall resistance rate among cephalosporin, cotrimoxazole, penicillin, and aminoglycosides classes were 90%, 88.9%, 77.3%, and 54.54%, respectively. Of all isolates, 58% (11) were multidrug-resistant, including all the non-lactose-fermenter Gram-negative rods and 71.4% of the Klebsiella pneumonia isolates. CONCLUSION: The prevalence of neonatal bacterial meningitis was 1.73%. Klebsiella pneumonia and other Gram-negative rods, with a high multidrug-resistant rate, were the leading cause of neonatal bacterial meningitis. Further studies are needed to explore the source of infection, incidence, and risk factors of neonatal bacterial meningitis.
