Article Synopsis
  • This study aims to quickly and accurately detect the Y132F ERG11p mutation in Candida parapsilosis isolates and to analyze genetic diversity among these isolates for better tracking of fluconazole resistance.!* -
  • The research involved 223 isolates from patients across 20 hospitals in Spain and Italy, using newly optimized PCR methods that require no DNA extraction and provide results in as little as 1.5 hours.!* -
  • The findings confirm both PCR methods have 100% specificity and sensitivity, with Scheme 1 showing greater genetic diversity compared to Scheme 2, suggesting the use of specific microsatellite markers for better genotyping of resistant strains.!*

More than one million sexually transmitted infections (STIs) occur every day, and is responsible for more than 156 million cases each year worldwide. Nevertheless, epidemiological studies of this parasite in Europe are scarce. The aim of this study was to evaluate the impact that the COVID-19 pandemic may have had in the diagnosis and epidemiology of trichomoniasis.

Background: Fluconazole-resistant Candida parapsilosis is a matter of concern.

Objectives: To describe fluconazole-resistant C. parapsilosis genotypes circulating across hospitals in Spain and Rome and to study their azole-resistance profile associated with ERG11p substitutions.

Article Synopsis
  • The study builds on findings from the CANDIMAD study (2019-2021) regarding antifungal resistance in Madrid, revealing trends of increased fluconazole resistance in 2022 among isolates from blood cultures and intra-abdominal samples.
  • A total of 766 isolates were collected, with a notable rise in fluconazole resistance (12.0% overall, 16.0% in blood cultures), largely attributed to specific resistant clones, while resistance to other antifungals remained low.
  • The data indicates a concerning spread of fluconazole-resistant genotypes in Madrid, with up to 7 out of 16 hospitals reporting affected cases, highlighting the need for vigilance in antifungal treatment strategies.

Objectives: Antifungal susceptibility testing is mostly conducted on blood-cultured Candida spp isolates. Because the intra-abdominal cavity has been highlighted as a hidden echinocandin-resistant C. glabrata reservoir, we assessed whether testing sequential isolates from a given patient might increase the chances of detecting antifungal resistance.

Article Synopsis
  • Candidemia, often linked to medical implants, has seen rising cases of fluconazole-resistant strains in Spain, particularly during the COVID-19 pandemic.
  • A study analyzed 1,315 yeast isolates from 2000 to 2021, revealing increased instances of acquired resistance to fluconazole and voriconazole in various Spanish hospitals.
  • Three prevalent clones were identified, with a need for further research to understand their expansion and genetic connections.

Background: Candidaemia and invasive candidiasis are typically hospital-acquired. Genotyping isolates from patients admitted to different hospitals may be helpful in tracking clones spreading across hospitals, especially those showing antifungal resistance.

Methods: We characterized clusters by studying isolates (, = 1041; , = 354, and , = 125) from blood cultures (53.

Objectives: We prospectively monitored the epidemiology and antifungal susceptibility of Candida spp. from blood cultures and intra-abdominal samples in patients admitted to hospitals in the Madrid area.

Methods: Between 2019 and 2021, we prospectively collected incident isolates [one per species, patient and compartment (blood cultures versus intra-abdominal samples)] from patients admitted to any of 16 hospitals located in Madrid.

Severely ill COVID-19 patients are at high risk of nosocomial infections. The aim of the study was to describe the characteristics of candidemia during the pre-pandemic period (January 2019−February 2020) compared to the pandemic period (March 2020−September 2021). Antifungal susceptibilities were assessed using the EUCAST E.

Objectives: Vaginal and endocervical infections are considered a global health problem, especially after recent evidence of their association with preterm delivery and other adverse obstetric outcomes. Still, there is no consensus on the efficacy of a screening strategy for these infections in the first trimester of pregnancy. This study evaluated their prevalence and whether screening and treatment resulted as effective in reducing pregnancy and perinatal complications.

Trichomoniasis is the most prevalent curable sexually transmitted infection (STI) worldwide and a risk factor for the acquisition of other STIs and adverse pregnancy outcomes. The objectives of this study were to determine the prevalence of T. vaginalis and related coinfections in women attending a third-level hospital of Madrid (Spain).

Rapid diagnosis is one of the best ways to improve patient management and prognosis as well as to combat the development of bacterial resistance. The aim of this study was to study parameters that impact the achievement of reliable identification using a combination of flow cytometry and matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-ToF-MS).The study was carried out in nine hospitals in Spain and included 1,050 urine samples with bacterial counts of 5x106 bacteria/ml.

Objective: To evaluate the Sysmex UF-1000i system as a urine screening method for the diagnosis of urinary tract infection, and epithelial cells as a predictive value of contamination in woman of childbearing age.

Methods: A total of 1730 urine samples were processed using a urine culture as a reference.

Results: With 50 bacteria/μl as a cut-off point, the results were: sensitivity 91.
