: Interstitial fibrosis/tubular atrophy in kidney transplantation is an unspecific lesion induced by immune and non-immune factors, which determines the progression of chronic kidney disease. Hydroxyproline is an imino acid that is part of the molecule of collagen. The aim of this study was to assess hydroxyproline in urine microvesicles as a marker of fibrosis in the renal transplant patient.

Introduction: The 13-valent pneumococcal conjugate vaccine (PCV13) universal vaccination programme was introduced in December 2016 in Andalusia.
Methods: A cross-sectional study was conducted on the molecular epidemiology of pneumococcal nasopharyngeal colonization. A total of 397 healthy children were recruited from primary healthcare centres in Seville for the periods 1/4/2018 to 28/2/2020 and 1/11/2021 to 28/2/2022 (PCV13 period).
Background: Despite all efforts, the incidence of severe coronavirus disease 2019 (COVID-19) infection has been high in renal transplant recipients, as in other groups (eg, older adults, patients with comorbidities or immunosuppression). The detection of any possible predictor of gravity could improve the early approach in these patients.
Patients And Methods: We registered data from renal transplant recipients with severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) infection in our area for a year (March 2020 to March 2021).
An expanded library of matrix assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) has been constructed using the spectra generated from 42 clinical isolates and 11 reference strains, including 23 different species from 8 sections (16 cryptic plus 7 noncryptic species). Out of a total of 379 strains of Aspergillus isolated from clinical samples, 179 strains were selected to be identified by sequencing of beta-tubulin or calmodulin genes. Protein spectra of 53 strains, cultured in liquid medium, were used to construct an in-house reference database in the MALDI-TOF MS.

Our aim was to evaluate LGV prevalence and predictors in a high-risk population attending to two STI clinics in the southwest of Spain between December 2013 and April 2015.
Methods: Screening of C.
Objective: To assess the relevance of correct identification and interpretation of susceptibility testing of Aeromonas spp. bacteremia isolates using newly developed molecular methods in comparison to previous conventional methods.
Material And Methods: The study included 22 patients with bacteremia due to Aeromonas hydrophila group, microbiologically characterized using the MicroScan system.

Introduction: Campylobacter spp. is a major cause of acute bacterial diarrhea in humans worldwide, and C. coli is responsible for 10% of the cases.

The most important are an active efflux mechanism (MSB phenotype) and ribosomal target modification (MLSB phenotype); this latter mechanism confers resistance to all three groups of antimicrobials (MLSB resistance). Expression of MLSB resistance can be constitutive (cMLSB) or inducible (iMLSB).

Introduction: The aim of this study was to evaluate the feasibility of detecting Staphylococcus aureus and coagulase-negative staphylococci (CoNS) and of identifying methicillin resistance directly in positive BACTEC blood culture bottles using the LightCycler system.
Methods: One hundred thirty-one positive blood culture bottles in which Gram-positive cocci in cluster were observed after Gram staining and 40 positive bottles with microorganisms other than staphylococci were studied. A molecular assay based on an automated DNA extraction protocol with a MagNA Pure LC instrument was used.
