    ResumenObjetivoAnalizar la resistencia de Escherichia coli a los antibi贸ticos de acuerdo con la presencia de beta-lactamasas de espectro extendido (BLEE).Materiales y m茅todosEstudio descriptivo y de corte transversal, en el Hospital Departamental de Villavicencio, centro de atenci贸n de mediana y alta complejidad. La poblaci贸n de estudio fueron los pacientes con cultivos positivos para E. coli. La variable de estudio fue la resistencia a ceftazidima, cefotaxima y clavulanato. Se confirm贸 la presencia de BLEE y la resistencia a otros antibi贸ticos.ResultadosSe tamizaron 29.451 estudios de microbiolog铆a, de los cuales 26,7% fueron positivos. Se identificaron 77,6% como Gram negativos y 2.551 (41,8%) como E. coli. De los cultivos, 65,1% se obtuvieron de orina; 9,5% fueron resistentes a ceftazidima y 8,7% a cefotaxime. En los aislamientos de orina, la resistencia de E. coli a ceftazidima fue de 6,5%, mientras que, en aspirados traqueales, fue de 35,0% (OR=7,98; p<0,05). Se hicieron 315 pruebas confirmatorias para BLEE con equipo Vitek庐 y 506 con AutoScan庐. La mayor cantidad de muestras se obtuvieron de la consulta externa (34,0%) y, aunque all铆 se encontr贸 un n煤mero significativo de BLEE (6,9%), hubo mayor resistencia en la unidad neonatal (16,9%). La resistencia a ampicilina, cefalotina, ciprofloxacina, gentamicina y trimetoprim-sulfametoxazol, fue alta. El 7,1% de las pruebas confirmatorias con clavulanato fueron positivas para BLEE.ConclusionesEl estudio demostr贸 una frecuencia de 7,1% de BLEE en esta instituci贸n. Hubo servicios con mayor riesgo, como el de neonatos, aunque el fen贸meno no se limitaba al ambiente hospitalario. Tambi茅n, se encontr贸 un peque帽o porcentaje que fue resistente a carbapenem.AbstractObjectiveTo analyze antimicrobial resistance of Escherichia coli according to the presence of extended spectrum beta-lactamase.DesignA cross sectional descriptive study.SettingHospital Departamental de Villavicencio, a State center of second and tertiary care.Study populationPositive cultures for E. coli were analyzed between September 2005 and November 2009.InterventionsNone.Study variableCeftazidime and cefotaxime resistance with and without clavulanate.OutcomesConfirmation of ESBL test and resistance to other antimicrobials.ResultsFrom the 29,451 microbiological samples that were screened, 26.7% were positive. 77.6% were identified as Gram negative and 2,551 (41.8%) were typified as E. coli. 65.1% isolations were from urine samples and 9.5 and 8.7% of them were resistant to ceftazidime and cefotaxime, respectively. 6.5% of urine samples were resistant to ceftazidime, but it raised to 35% for tracheal aspirate (OR 7.98 p<0.05). Three hundred and fifteen confirmatory tests for ESBL were performed with Vitek庐 and 506 with AutoScan庐. Most samples were ambulatory patients (34.0%) and a significant number of them were positive for ESBL (6.9%), but it was higher at the newborn ward (16.9%). Resistance was high for antimicrobials commonly used for infections by this microorganism such as ampicillin, cephalothin, ciprofloxacin, gentamycin and trimethoprim-sulfamethoxazole. Confirmatory ESBL test was 7.1%.ConclusionsThe study demonstrates a 7.1% frequency of ESBL at this hospital but the samples from newborn ward showed a higher frequency of ESBL; nevertheless, the issue is not restricted to hospitalized patients. We also found a small number of isolations resistant to carbapenem

    Introduction:Epidemic Dengue fever is an ancient disease, however in the past 17 years, it鈥檚 activity has a dramatic resurgence of Dengue in the tropics areas worldwide. This increased of epidemic activity, has been associated with the geographical expansion of both, the mosquito vectors and the viruses, the development of hyper-endemicity, and the emergence of Dengue hemorrhagic fever. Objective: The goal of this study was to determine the frequency of Dengue infection in patients with acute febrile syndrome in Meta鈥檚 Administrative District, Colombia. That ask for a medical advice at the Departmental hospital of Villavicencio. Material and methods: Blood serum were collected from 100 febrile patients in of acute and convalescent stages from the rural and urban zones that arrive for medical advice to the Departmental hospital of Villavicencio during 2013 and 2014. Serologic tests for Dengue (IgM and IgG by ELISA) were performed. Statistical analyses were performed using SPSS 21.0 for Windows (SPSS Inc., USA).聽The chi-square test was used to make a comparison. Variables that were statistically significant (p&lt;0.05) were kept in the final model. Results: From a total of 100 persons surveyed, (51%) were women, and average age was 23,5 卤 15,6 years, 50%聽 was students聽 and聽 51 % had some type of Dengue, mainly secondary infections (44 %). Conclusions:Dengue is a frequent infection in Meta Administrative District, Colombia, with a high frequency of exposed population with secondary infection which is a risk factor for severe forms of the disease.Keywords: Febrile syndrome, Dengue, ELISA, antibody, IgM, IgG, Colombia.</p

    聽聽Identificar las especies de cucarachas y bacterias asociadas a su exoesqueleto en un centro hospitalario de la ciudad de Villavicencio (Meta, Colombia). M茅todos. Se realizaron capturas manuales de cucarachas en cocina, urgencias, UCI intermedia, consulta externa y neonatos. Los individuos col颅ectados fueron sometidos a un aislamiento primario en caldo BHI, para luego pasar a medios s贸lidos (sangre y MacConkey). Se realiz贸 identificaci贸n y antibiograma por m茅todo automatizado. Resultados. Se colectaron 24 ninfas y adultos de Blattella germ谩nica. Se aisl贸 e identific贸 Klebsiella pneumoniae con sensibilidad intermedia a meropenem (CMI 4) y resistencia a cefalosporinas (cefepima y cefuroxima) (&gt;16), Proteus vulgaris con resistencia a cefalosporinas (ceftriaxona, cefuroxima) (CMI &gt;16), Enterobacter cloacae con resistencia a cefalosporinas (cefoxitina, cefuroxima, ceftriaxona) (CMI &gt; 16), Enterococcus faecium, Enterococcus rafinosus, Staphylococcus xylosus y Enterococcus faecalis. El 80% de las bacterias aisla颅das presentaron alg煤n grado de resistencia a antibi贸ticos. Conclusiones. Estos insectos podr铆an jugar un papel importante en la transmisi贸n de las Infecciones asociadas a la atenci贸n en salud (IAAS). Debido a su presencia en hospitales y el reporte de IAAS y resistencia bacteriana en varios centros asistenciales en el Departamento del Meta, se hace necesario establecer la relaci贸n de estos insectos con estos eventos
