Sepsis is a serious, life-threatening condition, occurring when an infectious agent invades the body, resulting in systemic inflammatory response syndrome (SIRS). Neonates and children are among the most vulnerable population groups of developing sepsis because of their weak immune barrier. Despite major advances in prevention, diagnosis and treatment of bacterial infections, invasive infections followed by sepsis remain one of the leading causes of childhood mortality. The aim of this study was to identify bacterial agents and antimicrobial resistance patterns of aerobic bacteria among children suspected of having sepsis. This cross-sectional descriptive type of observational study was conducted in the Department of Microbiology, Mymensingh Medical College, Bangladesh from March 2021 to February 2022. Blood samples were collected from pediatric patients, suspected of having sepsis referred from inpatient facility of department of Neonatology and Pediatrics, Mymensingh Medical College Hospital (MMCH). Blood samples were inoculated into BacT/ALERT PF Plus bottles followed by sub-culture of positive samples in blood agar, MacConkey agar and chocolate agar plates. Isolated bacteria were identified by routine biochemical tests. Antimicrobial resistance pattern of all isolated bacteria was seen by disk diffusion method. MIC of vancomycin by agar dilution method was determined for isolated S. aureus and Coagulase negative Staphylococci (CoNS). The prevalence of pediatric sepsis was 31.82% with highest isolation rate 35.55% among neonates. The isolation rate of gram-positive bacteria was 62.50% where S. aureus was the most common isolate 32.15% followed by CoNS 30.36%. Out of 21 gram-negative bacteria, Pseudomonas spp. was the most frequent isolate 7(33.33%), all of which were resistant to cefuroxime, ceftriaxone and ceftazidime along with all klebsiella and Acinetobacter isolates. Out of 18 S. aureus isolates, 94.44%, 88.89% and 66.67% were resistant to Azithromycin, Penicillin-G and Ciprofloxacin respectively. The MIC of Vancomycin by agar dilution method was observed <2μg/ml against all isolated S. aureus and CoNS. All the Gram-positive isolates were sensitive to Linezolid and Vancomycin. Early detection of bacteria followed by antimicrobial susceptibility test can help by selection of appropriate antibiotic and prevent spread of infection. |
