The following factors are conducive to develop infections caused by opportunistic bacteria: invasive research methods, medical treatments and immunological defects. The publication presents pathogenicity of bacteria of following types: Aerococcus, Kocuria, Kytococcus, Lactococcus, Leuconostoc, Micrococcus, Pediococcus. There are also mentioned diagnostic and treatment issues in the publication. The purpose of this study is to draw attention to infection caused by opportunistic bacteria, which are ingredients of physiological flora as well as diagnostic difficulties, which occur in case of isolation of this pathogens. Quick and correct diagnosis of etiological factor and applying of proper treatment can have very important impact on effectiveness of therapy and decrease of mortality in this kind of infections.
