Abstract
Exploring the complex dynamics of bioaerosols within arid climates, this observational study delves into the microbial composition and seasonal variability of airborne pathogens in Qatar. Utilizing a Coriolis® μ sampler across ten strategically selected sites, the research captures a full year of data spanning from November 2021 to September 2022. Our analysis reveals pronounced seasonal fluctuations in microbial concentrations, with peak bacterial levels observed during the summer and maximum fungal densities during the winter. This study not only highlights significant variations in bioaerosol loads but also uncovers robust antibiotic resistance, particularly to Metronidazole, during the hot season. These findings are critical for developing targeted public health strategies and enhancing environmental monitoring frameworks in regions facing similar arid conditions.
