Molecular Identification and Antifungal Susceptibility of Fusarium spp. Clinical Isolates.

Background: Accurate identification of Fusarium species requires molecular identification. Treating fusariosis is challenging due to widespread antifungal resistance, high rates of treatment failure, and insufficient information relating antifungal susceptibility to the clinical outcome. Despite recent outbreaks in Mexico, there is limited information on epidemiology and antifungal susceptibility testing (AST).

Rapid Detection of Carbapenemases Using NG-Test CARBA 5 in Positive Blood Cultures: A Diagnostic Test Study.

Background: Infections due to carbapenem-resistant Gram-negative bacteria are emerging as an important challenge in health-care settings and a growing concern worldwide. Lateral flow immunoassay NG-Test CARBA 5 can detect the five most reported carbapenemases (KPC, OXA-48-like, VIM, IMP, and NDM). Direct testing of positive blood cultures could reduce time to detection.

Evaluation of Primers OPF-01, P54, and 1253 to Identify , , and from Polymorphic Patterns Obtained by RAPD-PCR.

We evaluated the specificity of the primers OPF-01, P54, and 1253 to identify , , and , respectively, with the RAPD-PCR method. Eighty-two isolates belonging to the sections , , and were used. The isolates were identified by phenotypic (macro- and micromorphology) and genotypic (partial sequences of the gene) methods.

Predictors of Mortality in Patients with Infections Due to Carbapenem-Resistant Gram-Negative Bacteria.

Introduction: Infections caused by carbapenem-resistant Gram-negative bacteria (CR-GNB) are a significant cause of mortality and represent a serious challenge to health systems. The early identification of mortality predictors could guide appropriate treatment and follow-up. We aimed to identify the factors associated with 90-day all-cause mortality in patients with CR-GNB infections.
