Aim. To analyze the variety composition of microorganisms which colonize the vascular and urinary catheters in patients, who stayed in reanimation and intensive care departments of multi-field hospital.
Materials and methods: The study was carried out on the base of multi-field hospital of National military-medical clinical center of ME of Ukraine in 2013-2015. There was determined the frequency of microbial biofilms formation on vascular and urinary catheters. The analysis of colonization of vascular and urinary catheters by causal organisms of infectious complications was realized.
Results: The frequency of microbial biofilms creation on vascular catheters was 55,6 %, on urinary ones – 97,7 %. It was established, that in the spectrum of causal organisms of catheter-associated infection in vascular catheters prevailed coagulozonegative staphylococci (29,3%), whereas in urinary ones - Enterococcus faecalis (31,8%) of all conventionally pathogenic microorganisms (CPM). The infection, conditioned by Candida fungi was revealed in 11,5% of cases.
Conclusions: At the study of material from vascular catheters, microorganisms were separated mainly in microbial associations, whereas biofilms on uninary catheters were formed by several varieties of microorganisms in most cases. Creation of biofilms on implanted biomaterials gives them the clinical importance, because the infected device acts as a reservoir of pathogenic microorganisms, resistant to the components of immune system and antimicrobial agents
