چکیده

Background: Neonatal sepsis is one of the most important causes morbidity and mortality among neonates, particularly in developing countries. This study aimed to determine risk factors vitro antibiotic susceptibility patterns bacterial pathogens associated with neonatal Federal Medical Centre (FMC) Turai Umaru Yar’adua Maternal Children Hospital (TUYMCH), Katsina, Nigeria.Methodology: A total 60 hospitalized neonates evaluated for at special care baby units (SCBU) two healthcare facilities whose parents gave informed consent were enrolled between July December 2020. Blood samples aseptically collected from cultured on BacT/Alert automated platform (BioMérieux, Mercy-Etoile, France) machine. Bacteria identified all positive cultures test was performed isolates their minimum inhibitory concentrations (MICs) eight selected antibiotics using Vitek-2 compact system. Data analyzed by SPSS version 22.0.Results: clinical features suggestive enrolled. The mean age 1.35±0.48 days while weight 2.13±0.89 kg. Neonates early onset (<3 days) constituted 65% those late-onset (>3 35%. Thirty-one (51.7%) culture 29 (48.3%) negative pathogens. Gram-positive bacteria predominated, constituting 80.6% Gram-negative 19.4%. frequent coagulase-negative staphylococci (51.6%, 16/31), Staphylococcus haemolyticus 5 (16.1%) predominating, isolate Escherichia coli 2 (6.5%). high degree resistance (>50% rate) exhibited against tested including third generation cephalosporins fluoroquinolones. Gentamicin only effective, 65.5% sensitive it; 68.0% Gram-positives 50.0% Gram-negatives. Vancomycin also effective bacteria, it. Previous premature delivery (64.5%, 20/31) home respectively maternal significantly culture-positive (OR=2.975, 95% CI=1.040-8.510). There no significant difference respect manifestations such as refusal feeds, fever, jaundice, fast breathing, convulsion body temperature (p>0.05).Conclusion: a substantial cause admitted FMC TUYMCH, Nigeria. need regular surveillance factors, causative organisms, isolated pathogens, inform choice empirical treatment pending results blood cultures.
