Characterization of the Differential Pathogenicity of Candida auris in a Galleria mellonella Infection Model

2021

ABSTRACT Candida auris is an emergent multidrug-resistant fungal pathogen considered a severe global threat due to its capacity to cause nosocomial outbreaks and deep-seated infections with high transmissibility and mortality. However, evidence on its pathogenicity and the complex host-pathogen interactions is still limited. This study used the in vivo invertebrate model in Galleria mellonella to assess its virulence, exploring the mortality kinetics, melanization response, and morphological changes after fungal infection compared to Candida albicans and Candida parapsilosis, with known high and low pathogenicity, respectively. All C. auris isolates presented less virulence than C. albicans…

International Multicentre Study of Candida auris Infections

2021

Background:Candida auris has emerged globally as a multi-drug resistant yeast and is commonly associated with nosocomial outbreaks in ICUs. Methods: We conducted a retrospective observational multicentre study to determine the epidemiology of C. auris infections, its management strategies, patient outcomes, and infection prevention and control practices across 10 centres from five countries. Results: Significant risk factors for C. auris infection include the age group of 61–70 years (39%), recent history of ICU admission (63%), diabetes (63%), renal failure (52%), presence of CVC (91%) and previous history of antibiotic treatment (96%). C. auris was commonly isolated from blood (76%). Echi…

The Influence of Infection and Colonization on Outcomes in Inpatients With COVID-19 : Are We Forgetting Something?

2021

The COVID-19 epidemic has been a great challenge to health systems and especially hospitals. A prospective observational epidemiological study was planned as of February 26, 2020 in a tertiary hospital in the Valencia region. The total number of patients followed up with complete information during the first year was 2,448. Among other variables, the comorbidities of the patients were collected (and grouped in the Charson index), the stay in the intensive care unit (ICU), the co-infections, and the colonizations. Data on nosocomial infections due to said virus were also collected. The median days from the onset of symptoms to diagnosis were 4 + 4.6, while an additional 4.4 days had to pass …

The global challenge of Candida auris in the intensive care unit

2019

Since the first isolation of Candida auris in 2009, scientific community has witnessed an exponential emergence of infection episodes and outbreaks in different world regions. It is hard to predict future C. auris diffusion. By now, global surveillance, improving knowledge, and taking care of the A.U.R.I.S. major issues may be the best ways to face C. auris challenge

Analysis of Candida auris candidemia cases in an Intensive Care Unit of a tertiary hospital

2021

Abstract Candida auris is a multi-resistant emerging fungus. Objectives To analyze the relationship between colonization by C. auris and the appearance of invasive candidiasis. Description of the sample of colonized patients, risk factors for colonization and/or infection, and calculation of mortality rates. Methodology Longitudinal observational study in an anesthesia intensive care unit in 2018. Results 2130 patients were admitted. Surveillance studies were positive in 124 patients; 118 cases involved skin colonization and 52 were pharyngeal. Patients with a positive blood culture were identified. A statistically significant association was found between pharyngeal colonization and the ap…

Oligonucleotide-capped nanoporous anodic alumina biosensor as diagnostic tool for rapid and accurate detection of Candida auris in clinical samples.

2021

[EN] Candida auris has arisen as an important multidrug-resistant fungus because of several nosocomial outbreaks and elevated rates of mortality. Accurate and rapid diagnosis of C. auris is highly desired; nevertheless, current methods often present severe limitations and produce misidentification. Herein a sensitive, selective, and time-competitive biosensor based on oligonucleotide-gated nanomaterials for effective detection of C. auris is presented. In the proposed design, a nanoporous anodic alumina scaffold is filled with the fluorescent indicator rhodamine B and the pores blocked with different oligonucleotides capable of specifically recognize C. auris genomic DNA. Gate opening modul…

Análisis epidemiológico, clínico y microbiológico del brote de candidiasis invasora por Candida auris en el Hospital Universitario y Politécnico La Fe

2020

INTRODUCCIÓN: Candida auris es una levadura patógena responsable de brotes hospitalarios, especialmente en las unidades de cuidados intensivos (UCI). C. auris tiene características que la hacen muy diferente de otras especies de Candida: i) Los métodos comerciales basados en técnicas fenotípicas no la identifican, ii) ha surgido de forma independiente y simultánea en tres continentes; iii) presenta una elevada resistencia a los antifúngicos, pudiendo llegar a ser multirresistente; y iv) persiste durante semanas en el entorno hospitalario y además puede colonizar indefinidamente a los pacientes favoreciendo la trasmisión de paciente a paciente, principalmente en pacientes en estado crítico. …
