Objectives: Few studies have investigated pharyngeal colonisation in the United Arab Emirates (UAE). This study aims to identify the pharyngeal organisms present in a cohort of medical students with and without symptomatic pharyngitis.
Methods: This study was conducted between September 2016 and June 2018 at the College of Medicine and Health Sciences, UAE University, Al-Ain. Nasopharyngeal swabs were collected from preclinical and clinical medical students attending the college during the study period. The specimens were tested for 16 viral and nine bacterial pathogens using a real-time polymerase chain reaction assay.
Results: A total of 352 nasopharyngeal swabs were collected from 287 students; of these, 22 (7.7%) had pharyngitis symptoms. Overall, the most common isolates were human rhinovirus, and , with no significant differences in terms of gender, year of study or stage of study. The prevalence of in asymptomatic and symptomatic students was 1.1% and 0%, respectively. A Centor score of ≥2 was not associated with -positive samples. Six pathogens were isolated from symptomatic students including . was not detected in any of the samples.
Conclusion: The diagnosis and management of pharyngitis should be tailored to common pathogens in the region. This study found that and were not detected among students with symptoms of pharyngitis; moreover, Centor scores of ≥2 were not associated with the presence of . This cut-off score therefore should not be employed as an empirical measure to initiate penicillin therapy in this population.

Background: The activation of macrophages or microglia in patients' whole body or local eyes play significant roles in diabetic retinopathy (DR). Mitochondrial function regulates the inflammatory polarization of macrophages. Therefore, the common mechanism of mitochondrial related genes (MRGs) and macrophage polarisation related genes (MPRGs) in DR is explored in our study to illustrate the pathophysiology of DR.
