Outbreak of Acinetobacter baumannii producing OXA-66 in a Spanish hospital: epidemiology and study of patient movements
We describe an outbreak of multidrug-resistant Acinetobacter baumannii producing OXA-66 carbapenemase and resistant to imipenem. We analyze the relationship between the spread of this strain and patient movements within the hospital. Thirty-one isolates of A. baumannii recovered from December 21, 2006, to February 18, 2007, were studied. Enterobacterial repetitive intergenic consensus PCR and randomly amplified polymorphic DNA genotyping methods were used to define clusters of clonally related isolates. Pulsed-field gel electrophoresis was used to confirm the results and to check the maintenance of the epidemic strain over the following year. Antibiotic susceptibility testing was performed by microdilution and E-test. The isolates were screened by PCR analysis with primers specific for carbapenemase genes. With the exception of colistin (0%) there were no antibiotics with good activity against these isolates. The epidemiology study revealed that the same strain was responsible for all the infections. This strain appeared to carry the bla(OXA-66) gene. ISAba1 was present upstream the oxacillinase gene. The clone responsible for the outbreak is still present in hospital.1.936 JCR (2010) Q3, 43/58 Infectious diseases, 67/107 Microbiology, 143/252 Pharmacology & pharmac
In vitro activity of tedizolid (TR-700) against linezolid-resistant staphylococci
Objectives: To compare the activity of tedizolid (formally known as torezolid and TR-700) with that of 15 agents
against a collection of linezolid-resistant staphylococci (164 coagulase-negative staphylococci and
5 Staphylococcus aureus).
Methods: Antimicrobial susceptibility tests were performed using the broth microdilution method following the
recommendations of the CLSI.
Results: All isolates were susceptible to vancomycin and tigecycline. Based on the MIC90 values, the potency of
tedizolid against coagulase-negative staphylococci was .16-fold greater than that of linezolid. Tedizolid
retained activity against most of the linezolid-resistant staphylococci tested, including multidrug-resistant isolates
with elevated linezolid MICs (32 to .128 mg/L). Of the isolates, 79.2% and 31.4% were inhibited by
tedizolid at ≤4 mg/L and ≤2 mg/L, respectively.
Conclusions: The results of this study confirm the activity of tedizolid against linezolid-resistant staphylococci. This
new oxazolidinone could have an important role as a potential therapeutic agent against multidrug-resistant
staphylococci.5.338 JCR (2012) Q1, 7/69 Infectious diseases, 16/116 Microbiology, 18/260 Pharmacology & pharmac
Uso de la senda botánica UE como herramienta docente en la integración de competencias en fisiología
En los últimos años, varios estudios han constatado una tendencia hacia la integración de materias y contenidos en la educación superior. En este sentido, un grupo de profesores de Fisiología de los Grados de Farmacia, Biotecnología y Medicina han desarrollado una actividad multidisciplinar y multiárea, utilizando como herramienta la Senda Botánica UE. En ella, los alumnos deben reconocer una de las especies botánicas, y explicar el mecanismo de acción, la farmacología y la toxicología de uno de los principios activos de esa especie, y presentar los resultados en formato póster. Los alumnos fueron preguntados por su impresión antes y después de realizar la actividad. Los resultados generales muestran un alto grado de satisfacción del alumnado con la realización de actividades fuera del aula tradicional y con la inclusión de herramientas complementarias al contenido habitual de la asignatura. Asimismo, encuentran beneficios en la exposición de los resultados en formato póster frente a otros como el power point. Estos resultados nos animan a continuar con la integración de contenidos de diferentes áreas para lograr un aprendizaje más integral de los contenidos.SIN FINANCIACIÓNNo data 2015UE
Clinical outbreak of linezolid-resistant Staphylococcus aureus in an intensive care unit
Linezolid resistance is extremely uncommon in Staphylococcus aureus. Our objective was to report an outbreak with linezolid and methicillin-resistant S. aureus (LRSA) in an intensive care department and the effective control measures taken. Outbreak study of consecutive critically ill patients colonized and/or infected with LRSA at an intensive care department of a 1000-bed tertiary care university teaching hospital in Madrid, Spain. Patients were placed under strict contact isolation. Daily updates of outbreak data and recommendations for the use of linezolid were issued. Extensive environmental sampling and screening of the hands of health care workers were performed. Our measures were linezolid use and clinical and epidemiological characteristics and outcomes using minimal inhibitory concentrations, pulsed-field gel electrophoresis, and polymerase chain reaction of LRSA isolates. Between April 13 and June 26, 2008, 12 patients with LRSA were identified. In 6 patients, LRSA caused ventilator-associated pneumonia and in 3 patients it caused bacteremia. Isolates were susceptible to trimethoprim-sulfamethoxazole, glycopeptides, tigecycline, and daptomycin. Genotyping identified 1 predominant clone and 3 other types. Cfr-mediated linezolid resistance was demonstrated in all isolates. Potential hospital staff carriers and environmental samples were negative except for one. Six patients died, 5 of them in the intensive care unit, with 1 death attributed to LRSA infection. Linezolid use decreased from 202 defined daily doses in April 2008 to 25 defined daily doses in July 2008. Between July 2008 and April 2010, no new cases have been identified in the weekly surveillance cultures or diagnostic samples. In conclusión, the first clinical outbreak, to our knowledge, with LRSA mediated by the cfr gene developed at our center, was associated with nosocomial transmission and extensive usage of linezolid. Reduction of linezolid use and infection-control measures were associated with the termination of the outbreak.30.011 JCR (2010) Q1, 3/153 Medicine, general & interna
Resistance to linezolid is mediated by the cfr gene in the first report of an outbreak of linezolid-resistant Staphylococcus aureus
From April through June 2008, we identified 12 patients in the intensive care unit and 3 patients on other wards infected with methicillin-resistant Staphylococcus aureus that was also resistant to linezolid. We investigated the mechanism of resistance--point mutations in domain V of 23S ribosomal RNA (rRNA) or presence of the cfr gene--involved in the outbreak. Strains for the study were obtained in the intensive care unit and other wards. Minimal inhibitory concentrations were determined using automated methods, the E-test, or dilution in Mueller-Hinton agar in accordance with Clinical and Laboratory Standards Institute guidelines. Strains were genotyped using pulsed-field gel electrophoresis and were sequenced to determine the presence of point mutations in 23S rRNA. The presence of the cfr gene was determined by specific polymerase chain reaction. The result was that the minimal inhibitory concentrations of linezolid ranged from 16 mg/L to 32 mg/L, and all the strains were susceptible to tigecycline, vancomycin, and daptomycin. Typing of strains sequentially isolated by pulsed-field gel electrophoresis showed that each patient carried only 1 clonal type of linezolid-resistant, methicillin-resistant S. aureus as detected by sequential isolations. The presence of the cfr gene was confirmed in all the isolates. Furthermore, sequencing of domain V of 23S rRNA showed that the most common mechanism of linezolid resistance reported to date, mutation G2576T, was not detected in any of the strains analyzed. In conclusion, we report the presence of the cfr gene underlying the resistance mechanism involved in a clinical outbreak of linezolid-resistant S. aureus.8.186 JCR (2010) Q1, 11/134 Immunology, 2/58 Infectious diseases, 9/107 Microbiolog
A Botanic Trail as a Complementary Tool to Master Class in Physiology. A Comparison of Students’ Impression in Different Grades
In the last years, European Universities have rearranged their study programs
towards more practical contents in order to develop a broader range of
competences in the students. In this sense, a group of Lecturers in Physiology of
different Degrees (Pharmacy, Biotechnology and Medicine) have developed
multidisciplinary activity, included in the problem based learning methodology,
and supported on a tool previously established in the University Campus: the
Botanic Trail. This tool consists on the identification of the plant species located
in the Campus by means of signs with the QR codes, whose capture leads to a
website (www.sendabotanicaue.es) containing extensive information about
botany, pharmacognosy and the toxicology of each species. The activity started
when each group of 4-5 students of the first or second year were assigned a plant
found in the Campus. Then, the students should investigate their active
ingredients and explain the mechanism of action, pharmacology, medical
application and toxicology of at least one of these ingredients. The results of this
investigation should be presented in a poster format and explained to the rest of
the class. The students’ impression about the activity was recorded before and
after its development with a questionnaire. The analysis of the data collected
shows that, initially, students of the three Degrees agreed with the inclusion of
resources, such as the Botanic Trail, as a complement to master classes.
However, after carrying out the activity, a different point of view has emerged
depending on the Degree analyzed. Thus, Pharmacy-Biotechnology students
consider interesting the activity, and useful for complementing the theoretical
contents of the course in Physiology. However, Medicine students do not
consider that these types of activities make a significant difference on their
training, although they do not appear to be against including them. Taken
together, these results indicate a different assessment of the inclusion of
complementary resources to the master class depending on the profile of the
students.Sin financiaciónNo data (2016)UE
