Author: Sarkar et al. Summary: Infection control in cystic fibrosis (CF) patients plays a crucial role in improving the survival of patients with CF. Antimicrobial sensitivity patterns in these patient groups in our country are currently lacking. Therefore, the purpose of the study was to evaluate the microbiological cultures and antimicrobial susceptibility pattern of pediatric CF patients. A total of 50 respiratory samples were prospectively collected from the period between February 2021 and October 2021. Sputum and oropharyngeal swabs were processed for culture and microbiological testing. Sample collection and evaluation were performed according to the Good Laboratory Practice guidelines (GLP).
