Распространенность оксациллинрезистентных стафилококков в госпитальной среде и воздействие на них антибиотиков и дезинфектантов

Аннотация

Subjects of research: Ambient environment of hospital, (the air, washuts, nasopharynx of medical staff, microorganisms of surrounding ambience). Purpose of work: To determine the frequency of the spreading S.aureus and its resistance of oxacillin variant (MRSA) in surrounding ambience and in personnel of the clinics of the different profile, as well as to detect effect upon them antibiotics, antiseptics and disinfectants. Methods of research: Bacteriological, bactcrioscopic, epidemiological, statistical. The results obtained and their novelty: Retrospective sanitary-bacteriological studies made an analysis 8 of Urgench city of MPE for 2002-2006. OPE (Citrobactcr, Entcrobacter, Klebsiella) more frequent than S aureus was determined. Nasopharyngeal carriage of medical staff of S aureus and its resistance of oxacillin variant (MRSA) more in comparison with than checking group of healthy persons. Oxacillin- resistance S aureus (MRSA) has high level multiply resistance, atypical biochemical and cultural property, product ferment of pathogenicity than Oxacillinsensitive (MSSA). Practical value: Develop of speed fast screening method (6-8 hours) of the determination resistance S aureus to optimum set antibiotic. On base of the study factor to pathogen city MRSA is recommended as alternatives test of hyaluronidase (in the absence of or deficit rabbit plasmas) use, instead of coagulase test. Degree of embed and economic effectivity: Designed methodical instructions "Determination of sensitivity microorganism to antibacterial drugs by disco-diffusion method» (Tashkent, 2007). The Methodical instructions arc introduced in practical performance of the work bacteriological laboratories of CSSES of MPH RUz, as well as in training Urgench branch of Tashkent medical academy. Offered schemes of the studies arc more cheaply, nearly 4 times ( 125 sums in comparison with 550 sums), goal-antibiotic therapy will be quick recovery of the patient that shortens the days in permanent of hospital. Fied of application: Biology and medicine: bacteriological laboratories.
