Бак. посев из зева на микрофлору с определением чувствительности к антибиотикам

Aerobic and facultative anaerobic bacterial culture with antibiotic susceptibility testing and MIC determination isolates clinically relevant organisms from a wide range of specimens and reports targeted antimicrobial options. The assay supports differential assessment of aerobic versus anaerobic etiologies and is used to evaluate latent, indolent, or chronic infections by recovering persistent or hard‑to‑culture microorganisms. Results guide selection of an effective antibiotic regimen by linking organism identification with susceptibility and minimal inhibitory concentration data.

Anaerobes are organisms that do not require oxygen for growth; for many, oxygen is toxic. They are components of normal human microbiota of the gastrointestinal, respiratory, and genitourinary tracts. Infection may emerge endogenously when host defenses are impaired or tissue is disrupted, though exogenous acquisition also occurs (eg, deep puncture wounds or contaminated procedures). In soft tissues, anaerobic infections can manifest with firm edema, gas within tissues producing palpable crepitus, putrefactive inflammation, and a foul odor, and may present as cellulitis, abscesses, or myositis. Surgical management is primary—removing the nidus and opening the wound to oxygen, which is detrimental to obligate anaerobes. Aerobic bacteria require free oxygen and generate energy through oxidative pathways, whereas facultative anaerobes use anaerobic metabolism yet can grow in the presence of oxygen. Culturing these organisms demands appropriate media, controlled oxygen availability, and suitable temperatures; each species has defined oxygen tolerance limits. This assay detects aerobic and facultative anaerobic flora from clinical material. After culture growth, identifying the organism and performing antibiotic susceptibility testing allows selection of agents most likely to be effective in the specific case. Given the prevalence of antimicrobial resistance, empiric therapy based solely on broad spectra may be inadequate; susceptibility testing, including MIC determination, supports precise, targeted treatment.
