I Jornada sobre Bilógicos, Seguridad e Infección (BI-SEIF). Madrid, 19 de Septiembre de 2018

CARTA DE BIENVENIDA   Nos complace presentar las Primeras Jornadas sobre Biológicos Seguridad e Infección (BI-SEIF). Estas Jornadas nacen con el propósito de desarrollar las bases para el uso seguro de los nuevos fármacos biológicos dirigidos al tratamiento de cada vez más enfermedades en el campo de la Oncología, Hematología, Reumatología, Dermatología, Aparato Digestivo, Nefrología,…

Colonization with Enterobacteriaceae-Producing ESBLs, AmpCs, and OXA-48 in Wild Avian Species, Spain 2015-2016

Summary. Antibiotic resistance is a global threat of complex and changeable epidemiology. The role of wild birds in the dissemination of antibacterial resistance might be underestimated. We studied the cloacal colonization by cefotaxime-resistant Enterobacteriaceae in 668 wild birds in Spain. Eighty-eight wild birds (13.2%) of 28 species carried cefotaxime-resistant isolates; 58 of them (8.7%) carried…

Mechanisms leading to in vivo ceftolozane/tazobactam resistance development in Pseudomonas aeruginosa

REIPI researchers, led by H. Son Espases Group, Have characterized the mechanisms driving resistance development to the new antipseudomonal combination ceftolozane/tazobactam in 5 patients treated for MDR Pseudomonas aeruginosa infections. In all five cases, the same clone was detected for the susceptible/resistant pairs; the widespread ST175 high-risk clone in four of the cases and ST179 in the…

The urinary tract conditions of patients with Escherichia coli infection improve fosfomycin activity.

The steps by which E. coli strains harboring mutations related to fosfomycin resistance arise and spread during urinary tract infections (UTIs) are far from being understood. A study performed by several REIPI groups (Hospital Universitario Virgen del Rocío, Hospital Universitario Virgen Macarena and Centro Nacional de Biotecnología) evaluates the effects of the urinary tract conditions…

First insights into the role of vrf, a newly characterized gene of Salmonella Typhimurium

Salmonella Typhimurium is an important pathogen responsible for causing food-borne disease. This bacterium carries conserved virulence factors involved in the process of infection, allowing survival, replication and invasion inside the host cell in order to cause the disease. In this study, researchers from Dr. Jordi Vila’s group at the Barcelona Institute for Global Health (ISGlobal)-…

The prevalence and transmission dynamics of Escherichia coli ST131 among contacts of infected community and hospitalized patients

This study is the first assessment of longitudinal persistence of Escherichia coli ST131, including both ESBL and non-ESBL-producing isolates. This clone is considered the most important in the increased prevalence of quinolones resistant isolates and one of those responsible for the worldwide dissemination of the blaCTX-M-15 gene. Our results showed a rapid dynamic of ST131…

Optimisation of empirical antimicrobial therapy in patients with haematological malignancies and febrile neutropenia (How Long study): an open-label, randomised, controlled phase 4 trial

How Long? the just Continuation of empirical antimicrobial therapy (EAT) for febrile neutropenia in patients with haematological malignancies until neutrophil recovery could prolong the therapy innecessarily. We did an investigator-driven, superiority, open-label, randomised, controlled phase 4 clinical trial in six hospitals in Spain. For the experimental group, EAT was withdrawn after 72 h or more…

High Resolution Melting Assay to detect azole resistance in Aspergillus fumigatus

The global emergence of azole resistant Aspergillus fumigatus strains is a growing public health concern. Different patterns of azole resistance are linked to mutations in cyp51A. The Mycology Reference Laboratory of the National Centre for Microbiology has developed and validated a new screening sequencing-free molecular method based in a High Resolution Melting (HRM) assay to…

Empiric Therapy with Carbapenem-Sparing Regimens for Bloodstream Infections due to Extended-Spectrum β-Lactamase–Producing Enterobacteriaceae: Results from the INCREMENT Cohort.

This study, in advance access published in Clinical Infectious Diseases in August 2017, was coordinated at University Hospital Virgen Macarena with the collaboration of a large number of hospitals belonging to the REIPI/ESGBIS/INCREMENT group included in the REIPI network. The most relevant results, described below, can have a significant impact in the treatment and outcome…
