Clinical characteristics and outcome of bacteraemia caused by Enterobacter cloacae and Klebsiella aerogenes: more similarities than differences.

Objectives: The genus Enterobacter is a common cause of nosocomial infections. Historically, the most frequent Enterobacter species were those of Enterobacter cloacae complex and Enterobacter aerogenes. In 2019, E.

HCV microelimination strategies: An interventional study in diagnosed patients without access to the system.

Hepatitis C virus (HCV) one-step diagnosis improves recovery in patients with active infection. However, patients with previous anti-HCV+ may be excluded. We aimed to identify and retrieve non-referred or lost-to-follow-up HCV-infected patients.

A prospective, multicenter case control study of risk factors for acquisition and mortality in Enterobacter species bacteremia.

Background: Enterobacter is among the main etiologies of hospital-acquired infections. This study aims to identify the risk factors of acquisition and attributable mortality of Enterobacter bacteremia.

Methods: Observational, case-control study for risk factors and prospective cohort for outcomes of consecutive cases with Enterobacter bacteremia.

First report of NDM-1-producing clinical isolate of Leclercia adecarboxylata in Spain.

We describe the case of NDM-1-producing Leclercia adecarboxylata recovered from the clinical sample of a patient hospitalized for a trauma-related injury to his foot. The isolate was resistant to all beta-lactams, quinolones, trimetroprim-sulfametoxazol, gentamicin and tobramicyn. The bla gene was located in a conjugative plasmid that also contained the bla gene and was preceded by a disrupted insertion sequence of ISAba125.

[Application of mass spectrometry to bacterial identification].

Correct and rapid identification of bacteria is essential for the correct diagnosis and treatment of infected patients. Until a few years ago, biochemical, colorimetric or even antibiotic sensitivity tests were used to identify genera and species. The main limitations of these methods were the time needed for their performance and the difficulty of distinguishing between microorganisms that were little reactive, highly similar, or difficult to culture.

[Small-colony variants of Staphylococcus aureus: Usefulness of various test for diagnosis and susceptibility study].

Introduction: Small colony variants of Staphylococcus aureus (SCVSA) are a sub-population with special features.

Methods: The phenotypic features and antibiotic susceptibility of four clinical isolates SCVSA were studied.

Results: Colonies grew in the usual culture media, except in Mueller Hinton.

[Molecular typing methods for infection monitoring and control].

Molecular typing methods are useful in the surveillance and control of nosocomial outbreaks because they can provide information on the clonal relatedness among isolates, identify reservoirs, and determine routes of transmission. The gold standard assay for molecular typing is pulsed-field gel electrophoresis (PFGE) due to its high discriminatory power. Some major disadvantages of PFGE include the high cost of the equipment, its labor intensiveness (the technique is not automated) and the time required to analyze the profiles of DNA bands (pulsotypes).
