Бак. посев с раневой поверхости на микрофлору с определением чувствительности к антибиотикам

Wound exudate culture with antibiotic susceptibility and minimum inhibitory concentration (MIC) determination is used to isolate and identify aerobic bacterial pathogens from infected wounds and to direct antimicrobial therapy. After culture and species-level identification, susceptibility testing with MIC reporting (BD Phoenix platform) supports selection and adjustment of effective antibiotics when infection is suspected or treatment response is inadequate.

Wounds are frequent traumatic injuries, and contamination at the time of injury—such as exposure to soil, dust, or animal bites—along with closed spaces, foreign bodies, and devitalized tissue, promotes wound infection. Infection delays tissue repair and introduces the risk of local extension or systemic spread. When objective signs of a purulent inflammatory process arise in the wound or adjacent tissues, culture of wound drainage helps confirm the causative organism and determine antimicrobial susceptibility to inform effective treatment. Clinical features of wound infection include delayed healing, erythema, edema, localized warmth around the wound, persistent drainage, purulent exudate, and fever. Aerobic bacteria require free oxygen for energy generation and proliferation; in contrast to anaerobes, oxygen participates in their energy pathways. These prokaryotes reproduce by budding or binary fission and generate toxic oxidative byproducts. Successful cultivation of aerobic organisms depends on appropriate media, controlled oxygen levels, and optimal temperature. Each species grows within a characteristic range of oxygen concentrations. Facultative anaerobes complete their energy and reproductive cycles via anaerobic pathways yet are capable of growth in the presence of oxygen, distinguishing them from obligate anaerobes that cannot survive oxygen exposure. Facultative anaerobes obtain energy by catabolizing organic and inorganic substrates. Diagnostic workup involves culturing the clinical specimen, identifying the organisms recovered, and using this information to select antimicrobial agents active against the documented pathogen.
