Бак. посев отделяемого из наружного уха (правого) на микрофлору с определением чувствительности к антибиотикам

Wound exudate culture with antimicrobial susceptibility and minimum inhibitory concentration (MIC) determination isolates aerobic and facultative-anaerobic bacteria from infected wounds. The assay supports diagnosis of bacterial wound infection and directs antibiotic selection by reporting organism identity alongside susceptibility results. Clinicians use this culture, also referred to as an aerobic bacterial culture with susceptibility, to tailor therapy to the detected flora and improve treatment effectiveness.

Traumatic wounds are frequently complicated by contamination with soil, dust, animal bites, foreign bodies, closed spaces, and devitalized tissue, all of which promote infection. Infection slows tissue repair and can extend beyond the original site. When objective signs of a purulent inflammatory process appear in the wound or surrounding tissues, culture of wound drainage is indicated to identify the etiologic agent and determine its antimicrobial susceptibility, enabling selection of effective treatment. Common clinical signs include delayed healing, erythema, edema, localized warmth, persistent fluid drainage through a drain, purulent discharge, and fever. Aerobic bacteria require free oxygen and utilize it for energy generation; as prokaryotes, they lack a true nucleus and propagate primarily by binary fission (with budding described in some taxa). Successful cultivation depends on providing appropriate media, controlling oxygen availability, and maintaining optimal temperature, noting that each organism has a characteristic oxygen concentration range for growth. Facultative anaerobes carry out anaerobic metabolic pathways yet remain capable of growth in the presence of oxygen, in contrast to obligate anaerobes, which cannot survive in oxygenated environments. These organisms obtain energy by catabolizing organic and inorganic compounds. For infection assessment, the specimen is cultured, the recovered organisms are identified, and knowledge of the causative species allows selection of an active antimicrobial agent.
