Abstract:

Introduction: This study aimed to evaluate the frequency and typing of viral and bacterial pathogens in patients with a preliminary diagnosis of respiratory tract infection during the epidemic period in Türkiye. Material and Method: The study included the respiratory pathogen analysis results of 215 patients aged 0–17 years admitted to the Pediatrics Department of Kütahya Health Sciences University Evliya Çelebi Training and Research Hospital between October 2022 and March 2023 with symptoms of respiratory tract infections. Twenty-three viruses and six bacteria in the respiratory panel were studied using multiplex real-time PCR. Samples were obtained from a nasopharyngeal swab in non-intubated patients and tracheal aspiration material in intubated patients. Results: While 92.1% of the patients were positive for one or more agents, no agent was detected in 7.9%. Among the positive results, the rate of the single pathogen was 27.3% (n=54), while the rate of multiple pathogens was 72.7% (n=144). Respiratory syncytial virus was the most common viral agent with a rate of 23.3% and Adenovirus with a rate of 19.1%, while Haemophilus influenzae (48.8%) and Streptococcus pneumoniae (29.3%) were the most common bacterial agents. Conclusion: In this study, viral and bacterial pathogens have been studied intensively in children. Simultaneous, rapid, and sensitive detection of these agents is essential in preventing unnecessary antibiotic use and infection control. This is also important in terms of reducing mortality and morbidity rates.
