This revision describes in detail the different diagnostic techniques of catheter-related infection, both in terms of catheter removal and preservation. Culture techniques based on catheter withdrawal are classified depending on the detection of extraluminal and/or intraluminal colonization, and new methodologies are described. In general, the most important recommendations are: (a) do not send for culture catheter tips without suspicion of infection, (b) Maki's technique is the standard for detecting extraluminal colonization, (c) take 2 pairs of peripheral blood cultures before starting antibiotic treatment, (d) use skin and connections/connectors cultures for the conservative diagnosis due to their high negative predictive value (Gram and culture), and (e) take differential quantitative blood cultures though all catheter lumens and through a peripheral vein.

Introduction: Tularemia is a zoonotic disease that has been regularly reported in Spain since 1997. This study analyzes suspected, probable, and confirmed cases of tularemia in the province of Soria, and compares them with tularemia cases recorded in the autonomous community of Castilla y Léon, which, with the exception of 1 sporadic case, occurred in 2 epidemic outbreaks in 1997/1998 and 2007/2008.

Methods: We studied all patients (53) with signs and symptoms of tularemia in the period of 1997 to 2008.

We sought here to review the present definition of catheter-related bloodstream infections (CR-BSI) due to coagulase-negative staphylococci (CNS) by comparing the routine phenotypic methods with a genotypic procedure that considers different morphotypes. Our phenotypic characterization of CNS isolates included routine identification with biotype and antibiotype. The genotypic diagnosis was based on longer incubation periods with the consideration of all morphotypes and molecular typing by pulsed-field gel electrophoresis techniques.
