Посев кала на условно-патогенную флору с определением чувствительности к антибиотикам

Stool culture for opportunistic flora with antibiotic susceptibility testing (UPF test, opportunistic flora culture) supports the evaluation of suspected intestinal infection by identifying the causative opportunistic organism and its drug susceptibility profile. The assay also assists in the differential assessment of diarrheal illness alongside other studies when the presentation overlaps with inflammatory bowel disease, colorectal cancer, or malabsorption syndromes, and it aids in monitoring response to antibacterial therapy.

Opportunistic intestinal flora comprises microorganisms that commonly reside in humans at low abundance. When their numbers increase beyond expected levels, these organisms can contribute to disease. Frequent representatives include Staphylococcus aureus, Klebsiella, Escherichia, Enterobacter, Citrobacter, Acinetobacter, Proteus, Serratia, Pseudomonas, and yeasts such as Candida spp. Overgrowth or infection by these agents may manifest as gastroenteritis, enteritis, or enterocolitis. The stool culture for opportunistic flora characterizes these organisms qualitatively and quantitatively and determines their antibiotic susceptibility profile. The test is used to document infections caused by opportunistic bacteria or yeasts in the gastrointestinal tract and to inform selection of antimicrobial therapy.
