Distribution and antibiotic resistance patterns of airborne staphylococci in urban environments of Delhi, India.

ABSTRACT: Airborne microbial contamination, especially involving antibiotic-resistant bacteria (ARB) and antibiotic resistance genes (ARGs), poses a growing public health concern in urban environments. This study explores the prevalence and diversity of staphylococci, including methicillin-resistant staphylococci (MRS), in bioaerosols from various urban settings in Delhi, India. Indoor and outdoor air samples showed significantly high staphylococcal loads far above the WHO's recommended limit of 1000 CFU/m³ for microbial exposure. Seasonal variations revealed a peak in airborne MRS during winter, while monsoon rains reduced outdoor bioaerosol contamination. Eight staphylococcal species were identified, with Staphylococcus epidermidis and Staphylococcus arlettae being the most prevalent human- and an
