Бак. посев мочи на микрофлору с определением чувствительности к антибиотикам

Aerobic and facultative-anaerobic bacterial culture with antibiotic susceptibility testing and MIC determination is used to identify the causative organism in suspected bacterial infections and to distinguish aerobic from anaerobic involvement. The test supports evaluation of latent, low-grade, or chronic infections by recovering persistent or fastidious bacteria and informs targeted therapy through susceptibility results, including MIC values, to guide effective antimicrobial selection.

Anaerobic bacteria are microorganisms that grow without oxygen; for many obligate anaerobes, oxygen is toxic. They normally inhabit human mucosal sites—including the gastrointestinal tract, respiratory tract, and genitourinary system—and can cause endogenous infection when host defenses are impaired or tissue is disrupted. Exogenous acquisition occurs less often and may follow deep puncture trauma, septic abortion, thoracic or abdominal injury, or implantation of hardware or prostheses. In skin, soft tissue, and muscle, anaerobic infections can present with tense edema, gas in tissues with palpable crepitus, foul odor, and putrid exudate, and they may lead to cellulitis, abscesses, or myositis. Primary management of established anaerobic soft-tissue infection is surgical source control, including opening and debriding the wound and exposing tissues to oxygen, which is lethal for obligate anaerobes. Aerobic bacteria require oxygen and use it in energy-generating pathways that can yield toxic oxidative byproducts. Successful cultivation depends on suitable media, controlled oxygen tension, and appropriate temperature; each species has defined oxygen requirements for optimal growth. Facultative anaerobes can sustain metabolism and replication in the absence of oxygen yet also grow in its presence; this contrasts with obligate anaerobes, which cannot survive exposure to oxygen. Culture of clinical material enables differentiation of aerobic from anaerobic disease and provides organism-level identification to guide therapy. This assay evaluates aerobic and facultative-anaerobic flora; when growth is obtained, antimicrobial susceptibility testing is performed, including determination of minimum inhibitory concentrations (MICs). Given increasing antimicrobial resistance, susceptibility testing refines drug selection by identifying agents with the highest likelihood of efficacy in the specific isolate recovered.
