Bloodstream infections: trends and evolution of incidence and etiology in a 12-year period (2010-2021).

Introduction: The epidemiological evolution of bloodstream infections (BSIs) in the last decade is not clearly defined. Our aim was to analyze the changes in the workload in our institution and to describe the evolution of the incidence and etiology of BSIs in a 12-year period, including the COVID-19 pandemic.

Methods: All blood cultures received in the laboratory of a tertiary general hospital between 2010 and 2021 were analyzed.

Comparative study of the etiology of nosocomial bacteremic pneumonia in ventilated and non-ventilated patients: a 10-year experience in an institution.

This study on bacteremic nosocomial pneumonia (bNP) demonstrates the importance of this condition both in patients undergoing and not undergoing mechanical ventilation. , Enterobacterales, and non-fermenting Gram-negative bacilli are all causative agents in ventilator-associated pneumonia (VAP) and hospital-acquired pneumonia (HAP), with a predominance of in HAP and of in VAP. Mortality in this condition is very high.

Antifungal resistance in Candida spp within the intra-abdominal cavity: study of resistance acquisition in patients with serial isolates.

Objectives: Antifungal susceptibility testing is mostly conducted on blood-cultured Candida spp isolates. Because the intra-abdominal cavity has been highlighted as a hidden echinocandin-resistant C. glabrata reservoir, we assessed whether testing sequential isolates from a given patient might increase the chances of detecting antifungal resistance.

Significant increase of CTX-M-15-ST131 and emergence of CTX-M-27-ST131 Escherichia coli high-risk clones causing healthcare-associated bacteraemia of urinary origin in Spain (ITUBRAS-2 project).

Objectives: To assess the microbiological characteristics of Escherichia coli causing healthcare-associated bacteraemia of urinary origin (HCA-BUO) in Spain (ITUBRAS-2 project), with particular focus on ESBL producers and isolates belonging to ST131 high-risk clone (HiRC). Clinical characteristics and outcomes associated with ST131 infection were investigated.

Methods: A total of 222 E.

The Gastrointestinal Tract Is Pinpointed as a Reservoir of , , and Genotypes Found in Blood and Intra-Abdominal Samples.

Background: spp., as part of the microbiota, can colonise the gastrointestinal tract. We hypothesised that genotyping spp.
