Pathogenic bacteria in upper respiratory tract

Pathogenic bacteria in the upper respiratory tract refers to several bacterial species capable of causing acute illnesses, including pharyngitis, sinusitis, otitis media, epiglottitis, and laryngotracheitis. Common pathogenic bacteria include Streptococcus pyogenes (primary cause of strep throat), Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Staphylococcus aureus, and Mycoplasma pneumoniae[1][2][3][4][6]. These organisms enter and colonize the mucosal surface of the respiratory tract, leading to a variety of symptoms due to inflammation, toxin production, and immune evasion. Diagnosis is typically confirmed by microbiological culture or rapid antigen testing. Treatment relies on antibiotics targeting bacterial cell wall or protein synthesis. Inappropriate antibiotic usage can encourage resistance and cause therapeutic complications, emphasizing the need for careful diagnosis and targeted intervention. This entry is not a valid single molecular target for drug development or biomarker usage.
