Popis: The aim of this study was to compare the diversity of microbial colonization on implant material from different individuals. Eubacterial DNA was extracted, separated and sequenced from orthopaedic metallic implant material, tissues or body fluids, and skin of 4 patients as well as from identical dental cement material from 10 individuals after revision and routine removal. Additionally, the composition of the bacterial population of the dental cement and the oral swab sample from one individual after direct extraction of bacterial DNA was compared to extraction after conventional microbiological enrichment. The latter investigation proved that the commonly used cultivation technique gave different results than direct extraction of DNA, especially as regards the detection of anaerobes. Comparing the bacterial colonization of implant materials from different patients showed significant individual diversity. The common focus on a constricted pathogen spectrum may have to be expanded toward a multispecies population. Moreover, the dependence of the bacterial population on the individual host has to be integrated in discussing implant colonization and infection.
