Evaluation of the EUROIMMUN Aspergillus antigen immunoenzyme assay in serum and bronchoalveolar lavage fluid samples.

Introduction: The most widely used marker for the diagnosis of invasive aspergillosis (IA) is the detection of galactomannan by ELISA. This study describes the evaluation of the results obtained by Euroimmun Aspergillus antigen ELISA (EIA-GM-E) in serum samples and bronchoalveolar lavage fluid (BAL) from patients at risk of IA, and compares these results with those obtained by Bio-Rad Galactomannan EIA (EIA-GM-BR).

Methods: Anonymous retrospective case-control comparative study in 64 serum samples and 28 BAL from 51 patients.

Virulence genes of Aeromonas spp. isolates from stool in Spain.

Introduction: The role of Aeromonas species in gastrointestinal disease is controversial. The aim was to analyze not only the virulence genes between different species of Aeromonas isolated from feces, but the distribution of these virulence genes between enterotoxigenic strains and co-pathogen strains.

Methods: Retrospective study of isolates of Aeromonas spp.

Characterization, antifungal susceptibility and virulence of Candida parapsilosis complex isolates in a tertiary hospital in Cantabria, Northern Spain.

Introduction: The correct identification of the species within the Candida parapsilosis complex has become relevant due to the resistance of Candida metapsilosis to antifungals. We describe the characteristics of the Candida parapsilosis complex isolates, with respect to antifungal resistance and biofilm formation.

Methods: We perform a descriptive cross-sectional study in 30 strains, collected in a tertiary hospital.

Epidemiology of Campylobacter spp. isolated from stool in a tertiary hospital in Cantabria, Northern Spain, from 2016 to 2020.

Background: The incidence of Campylobacter coli has increased and with greater resistance to antibiotics than Campylobacter jejuni.

Objectives: To determine the epidemiology distribution of Campylobacter spp. in our health area, and the sensitivity to commonly tested antibiotics.

Epidemiology of Aeromonas spp. isolated from stool in a tertiary hospital in Cantabria, Northern Spain, in the last five years.

Introduction: The role of Aeromonas species in gastrointestinal disease is controversial. The aim of this study was to know the epidemiological distribution of Aeromonas spp. isolated from stool in our health area, determine the existence of diarrhea as a significant symptom, identification of existing species in our environment and association as co-pathogen.

Possible role of HLA class-I genotype in SARS-CoV-2 infection and progression: A pilot study in a cohort of Covid-19 Spanish patients.

Human Leukocyte Antigen (HLA) includes a large set of genes with important actions in immune response against viral infection. Numerous studies have revealed the existence of significant associations between certain HLA alleles and the susceptibility and prognosis of different infectious diseases. In this pilot study we analyse the binding affinity between 66 class I HLA alleles and SARS-CoV-2 viral peptides, and its association with the severity of the disease.

Evaluation of Vitek-MS™ and Microflex LT™ commercial systems for identification of Acinetobacter calcoaceticus-baumannii complex.

Introduction: Acinetobacter is a genus that comprises a group of opportunistic pathogens responsible for a variety of nosocomial infections. The Acinetobacter calcoaceticus-Acinetobacter baumannii (Acb) complex includes some species of clinical importance, mainly A. baumannii, A.

Isolated De Novo Headache as the Presenting Symptom of Listeria Meningitis: A Report of 2 Cases.

Background: Headache is a frequent symptom at the onset of Listeria meningitis, accompanied by others such as fever, altered mental status and meningeal signs, but never reported so far as an isolated symptom.

Methods And Results: Two immunocompetent males, with no history of primary headaches, went to the emergency department because of headache. The first after a sudden severe, holocranial headache without other associated symptoms, and the second after a subacute, moderate oppressive headache in temples, which 8 days later added a mild left hemiparesis.
