Бак. посев из слизистой носа на микрофлору с определением чувствительности к антибиотикам

Aerobic and facultative anaerobic culture with antibiotic susceptibility testing and MIC determination is used to recover bacteria from clinical specimens and guide targeted therapy. The assay supports differential diagnosis between aerobic and anaerobic etiologies when interpreted alongside dedicated anaerobic culture and clinical findings. It assists in evaluating acute, indolent, or chronic bacterial infections, including those caused by fastidious organisms that may require optimized culture conditions.

Obligate anaerobes thrive only in the absence of oxygen, whereas aerobes require oxygen for energy production; facultative anaerobes can grow with or without oxygen. Anaerobic bacteria constitute part of the normal human microbiota of the gastrointestinal, respiratory, and genitourinary tracts, but trauma, tissue hypoxia, or immunosuppression can permit endogenous infection. Penetrating injuries, contaminated procedures, and deep wounds also introduce pathogens. Anaerobic soft tissue infections may present with tense edema, crepitus from gas production, putrid inflammation, and malodor. Surgical source control is central to management, including debridement and exposure of affected tissues to oxygen when appropriate. Culture-based differentiation complements clinical evaluation. Specimens are inoculated to media under controlled atmospheric conditions to recover organisms and determine whether growth represents aerobic or facultative anaerobic flora; obligate anaerobes require dedicated anaerobic culture methods. Once isolates are obtained, antimicrobial susceptibility testing with minimum inhibitory concentration (MIC) determination informs drug selection. Because antimicrobial resistance patterns are evolving, empiric selection based solely on expected spectra is frequently inadequate. The antibiotic panel tested is selected according to the recovered organism and the available commercial system and follows current guideline recommendations.
