  • A. Fastidious Organisms MCQ 1 Explanation: the Most Common
    MCQ Answer 1: A. Fastidious organisms MCQ 1 Explanation: The most common cause of culture-negative infective endocarditis in patients who have not been treated previously with antibiotics is fastidious organisms (1). In our patient, serology for Bartonella, Pasteurella and Coxiella was negative, but the Brucella antibody titer was 1:160 (reference range <1:20). Brucella titers higher than 1:160 in conjunction with a compatible clinical presentation are considered highly suggestive of infection especially in a non-endemic area (2), (3). Brucellosis can affect any organ system and cardiac involvement is rare, but endocarditis is the main cause of death due to brucellosis. Ideally, the diagnosis should be made by culture, however this test has a low sensitivity, is time-consuming, and poses a health risk for laboratory staff (4). HACEK organisms used to be considered the most common agent of culture-negative endocarditis, but with the current blood culture techniques, they can be easily isolated when incubated for at least five days. In our patient, the HACEK organism culture was negative at 5 days (5). Antibacterial therapy prior to blood culture sampling is a common cause of culture negative endocarditis. Our patient received empiric antibiotic therapy after the blood cultures were drawn. Valvular vegetations can be caused by noninfectious conditions and should be considered in the differential diagnoses of any patient with endocarditis. Nonbacterial thrombotic endocarditis (NBTE), such as marantic or Libman-Sachs endocarditis, happens in the setting of systemic lupus erythematosus, malignancy, or hypercoagulable state. The vegetations of NBTE are composed of fibrin thrombi that usually deposit on normal or minimally degenerated valves.

  • Blood Culture Bottles Incubation Period, 5 Days Or More?
    February 2015 02/2015 NEWSLETTER Best Practices in Blood Culture Collection Blood culture bottles incubation period, 5 days or more? Introduction Blood is one of the most important specimens re- ceived by the microbiology laboratory for culture, and culture of blood is the most sensitive method for de- tection of bacteremia or fungemia. As we all know that the blood stream infection is one of the most se- rious problems in all infectious diseases. In general, adult patients with bacteremia are likely to have low quantities of bacteria in the blood, even in the setting of severe clinical symptoms. In addition, bacteremia in adults is generally intermittent. For this reason, multiple blood cultures, each containing large volumes of blood, are required to detect bacteraemia. Prior to initiation of antimicrobial therapy, at least two sets of blood cultures taken from separate venipuncture sites should be obtained. The technique, number of cultures, and volume of blood are more important factors for detection of bacteremia than timing of culture collection. Length of Incubation of Blood Cultures In routine circumstances, using automated continuous monitoring systems such as Becton Dickinson BACTEC System, blood cultures need not be incubated for longer than 5 days (1, 2, 3, 4, 5). For laborato- ries using manual blood culture systems, 7 days should suffice in most circumstances (6). Patient suspected Infectious Endocarditis (IE) A recent study at the Mayo Clinic, in which one of the widely used continuous monitoring blood culture systems was used, demonstrated that 99.5% of non-endocarditis BSIs and 100% of endocarditis epi- sodes were detected within 5 days of incubation (1).
