Utility of Extended Blood Culture Holds for Isolation of HACEK Organisms- A Retrospective Multicenter EvaluationThe purpose of the study was to determine the recovery rate and time to detection for the HACEK bacteria using the standard blood culture incubation periods, and to evaluate the usefulness ...
These organisms can cause “culture negative endocarditis” meaning infection of the endocardium with vegetation formation despite blood cultures not showing evidence of bacteremia. The above organisms require special medium or prolonged incubation to be isolated. The most common causes of culture negative...
culture negative endocarditis [66].Contrary to previous notions about culturing HACEK organisms, which are very difficult, experience has shown that this group separates after an average incubation period of 3 days, with an average of 4.3 days when using automated blood culture systems [62, 67]....
