This article examines the etiology of purulent inflammatory diseases and the classical and modern bacteriological methods used for their detection. During the study, clinical samples were analyzed using microscopic, bacteriological, and molecular techniques. The results showed that, alongside traditional culture methods, molecular diagnostics provide high accuracy and improve treatment efficacy.
