Influence of the bacterial phenotypes on the clinical manifestations in Klebsiella pneumoniae bacteremia patients: A retrospective cohort study.

Ninety-four episodes of Klebsiella pneumoniae bloodstream infection were identified at a university hospital in Japan. After excluding extended-spectrum beta lactamase-producing strains, 83 blood isolates from these patients were assayed in terms of their bacterial phenotypes such as the mucoid and hypermucoviscosity phenotypes. Bacterial phenotypes were correlated with the patients' clinical manifestations.

[Usefulness of Procalcitonin Measurement for the Detection of Sepsis].

Procalcitonin (PCT) is a frequently used marker for bacterial sepsis. The present study was aimed to assess the usefulness of PCT measurement in patient with sepsis. We studied the relationship between serum PCT level and blood culture in clinical 209 cases admitted from January 2010 through June 2010.
