Análisis de resultados del Programa de Control de Calidad Externo SEIMC. Año 2018
2020
This article provides an analysis of the results obtained in 2018 by the participants inscribed in the External Quality Control Programme of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC), which includes controls for bacteriology, serology, mycology, parasitology, mycobacteria, virology, molecular microbiology, and genotypic bacterial resistance. The results obtained in 2018 confirm the excellent skill and good technical standards found in the vast majority of Spanish clinical microbiology laboratories, as shown in previous editions. However, the programme again shows that erroneous results can be obtained in any laboratory and even in clinically relevant deter…
Direct identification of microorganisms from thioglycolate broth by MALDI-TOF MS.
2017
We developed an easy MALDI-TOF MS-based assay to identify microorganisms directly from thioglycolate broth. A total of 101 positive thioglycolate broths inoculated with 15 different kinds of samples were evaluated. In 91 samples (90.1%), direct MALDI-TOF MS identifications were the same as those obtained after conventional laboratory procedures including subcultures. In 10 samples misidentified by direct processing, yeasts or mixed cultures grew in the thioglycolate subcultures, or high cellular debris hampered a correct analysis. This rapid method can provide a fast, clinically- relevant species-level identification without disturbing the daily workflow in clinical microbiology laboratorie…
Portraying infective endocarditis
2019
Infective endocarditis is a growing problem with many shifts due to ever-increasing comorbid illnesses, invasive procedures, and increase in the elderly. We performed this multinational study to depict definite infective endocarditis. Adult patients with definite endocarditis hospitalized between January 1, 2015, and October 1, 2018, were included from 41 hospitals in 13 countries. We included microbiological features, types and severity of the disease, complications, but excluded therapeutic parameters. A total of 867 patients were included. A total of 631 (72.8%) patients had native valve endocarditis (NVE), 214 (24.7%) patients had prosthetic valve endocarditis (PVE), 21 (2.4%) patients …
Análisis de resultados del Programa Externo de Control de Calidad SEIMC. Año 2008
2010
Resumen El Programa Externo de Control de Calidad de la Sociedad Espanola de Enfermedades Infecciosas y Microbiologia Clinica (SEIMC) incluye las areas de serologia, bacteriologia, virologia, parasitologia, micologia y micobacterias, entre otras. En este manuscrito se presenta un analisis general de los resultados remitidos por los participantes en los distintos controles del ano 2008. Los resultados obtenidos por los centros participantes confirman el buen nivel general de los laboratorios espanoles de microbiologia clinica de anos anteriores. A pesar de ello, el programa demuestra que se producen resultados erroneos, incluso en determinaciones de la mayor trascendencia y en cualquier labo…
Análisis de resultados del Programa Externo de Control de Calidad SEIMC. Año 2013
2015
Resumen El Programa de Control de Calidad Externo de la Sociedad Espanola de Enfermedades Infecciosas y Microbiologia Clinica incluye las areas de bacteriologia trimestral y mensual, serologia, micologia, parasitologia, micobacterias, virologia, microbiologia molecular y cargas virales del virus de la inmunodeficiencia humana-1, virus de la hepatitis C y virus de la hepatitis B. En este manuscrito se presenta el analisis de los resultados remitidos por los participantes en los controles enviados durante el ano 2013, exceptuando los correspondientes a cargas virales, que se presentan en un manuscrito aparte. Los resultados obtenidos confirman de nuevo la buena capacitacion general de los lab…
Tellurite-dependent blackening of bacteria emerges from the dark ages
2019
Environmental contextAlthough tellurium is a relatively rare element in the earth’s crust, its concentration in some niches can be naturally high owing to unique geology. Tellurium, as the oxyanion, is toxic to prokaryotes, and although prokaryotes have evolved resistance to tellurium, no universal mechanism exists. We review the interaction of tellurite with prokaryotes with a focus on those unique strains that thrive in environments naturally rich in tellurium. AbstractThe timeline of tellurite prokaryotic biology and biochemistry is now over 50 years long. Its start was in the clinical microbiology arena up to the 1970s. The 1980s saw the cloning of tellurite resistance determinants whil…
Management of cytomegalovirus infection in solid organ transplant recipients: SET/GESITRA-SEIMC/REIPI recommendations.
2016
Cytomegalovirus (CMV) infection remains a major complication of solid organ transplantation. Because of management of CMV is variable among transplant centers, in 2011 the Spanish Transplantation Infection Study Group (GESITRA) of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) developed consensus guidelines for the prevention and treatment of CMV infection in solid organ transplant recipients. Since then, new publications have clarified or questioned the aspects covered in the previous document. For that reason, a panel of experts revised the evidence on CMV management, including immunological monitoring, diagnostics, prevention, vaccines, indirect effects, tre…
