Vibrio mimicus is a bacterium that causes gastroenteritis; it is closely related to Vibrio cholerae, and can cause acute diarrhea like cholera- or dysentery-type diarrhea. It is distributed worldwide. Factors associated with virulence (such as hemolysins, enterotoxins, proteases, phospholipases, aerobactin, and hemagglutinin) have been identified; however, its pathogenicity mechanism is still unknown. In pathogenic Vibrio species such as V. cholerae, Vibrio. parahaemolyticus and Vibrio vulnificus, capsule, biofilms, lateral flagellum, and type IV pili are structures described as essential for pathogenicity. These structures had not been described in V. mimicus until this work. We used 20 V. mimicus strains isolated from water (6), oyster (9), and fish (5) samples and we were able to identify the capsule, biofilm, lateral flagellum, and type IV pili through phenotypic tests, electron microscopy, PCR, and sequencing. In all tested strains, we observed and identified the presence of capsular exopolysaccharide, biofilm formation in an in vitro model, as well as swarming, multiple flagellation, and pili. In addition, we identified homologous genes to those described in other bacteria of the genus in which these structures have been found. Identification of these structures in V. mimicus is a contribution to the biology of this organism and can help to reveal its pathogenic behavior.  相似文献

目的:建立测定参松养心胶囊中人参皂苷Rg1和Re含量的超高效液相色谱-蒸发光散射检测器(UPLC-ELSD)法。方法采用Waters ACQUITY UPLC BEH C18柱(100 mm ×2.1 mm,1.7μm)为色谱柱,以乙腈-水为流动相(梯度洗脱),流速为0.45 mL/min,柱温为35℃,进样量为2μL,ACQUITY ELSD检测器的漂移管温度为50℃,气体流量为30.0 psi。结果参松养心胶囊中人参皂苷Rg1和Re进样量分别在0.09108~1.1358μg和0.08306~1.03825μg范围内与峰面积线性关系良好,平均加样回收率分别为99.01%和99.25%,RSD分别为0.50%和0.36%( n=6)。结论与高效液相色谱(HPLC)法相比,UPLC法在不影响分离效果的情况下大大提高了参松养心胶囊中人参皂苷Rg1和Re的分离速度,同时减少了溶剂消耗。UPLC法可作为替代传统HPLC法的一种更方便、快捷、可靠的方法。  相似文献

IntroductionSmall bowel capsule endoscopy (SBCE) is a non-invasive diagnostic technique whose use in inflammatory bowel disease (IBD) has spread. A panenteric capsule, PillCam Crohn's (PCC), has recently been developed. We lack information on the availability and use of the CEID and PCC in our environment.MethodsWe conducted an electronic and anonymous survey among the members of the Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa (GETECCU) [Spanish Working Group on Crohn's Disease and Ulcerative Colitis] and the Asociación Española de Gastroenterología (AEG) [Spanish Association of Gastroenterology], consisting of 37 multiple-choice questions.ResultsOne hundred and fifty members participated, the majority dedicated to IBD (69.3%). 72.8% worked at centres with an IBD unit. 79% had SBCE available at their hospital, 14% referred patients to another centre; 22% had a PCC available, 9% referred patients to another centre. 79.3% of respondents with available SBCE used it in a small percentage of patients with IBD and 15.6% in the majority. The most frequent scenarios were suspicion of Crohn's disease (76.3%), assessment of inflammatory activity (54.7%) and assessment of the extent of the disease (54.7%). More than half (59.7%) preferentially used the Patency capsule to assess intestinal patency. Almost all respondents (99.3%) considered that training resources should be implemented in this technique.ConclusionsSBCE is widely available in Spanish hospitals for the management of IBD, although its use is still limited. There is an opportunity to increase training in this technique, and consequently its use.  相似文献

Introduction and aimGraft-versus-host disease (GvHD) is a complication of hematopoietic cell transplantation, and the small bowel is one of the main targets in the gastrointestinal tract. Capsule endoscopy is a safe procedure and can be useful in the diagnosis of GvHD. The aim of the present study was to compare the diagnostic yield of capsule endoscopy with the histopathologic findings in GvHD.Materials and methodsA retrospective diagnostic test study included all the patients with suspected GvHD that underwent gastroscopy and colonoscopy, with histopathologic evaluation of the biopsies taken, and capsule endoscopy, within the time frame of July 2015 and July 2019. Capsule endoscopy findings were compared with the histopathologic diagnosis, considered the gold standard.ResultsTwenty-one patients with GvHD (7 [33%] women; 37 ± 11.9 years of age) were included, 20 (95%) of whom had acute GvHD. The median gastric transit time of the capsule was 55 minutes (20-113) and the median small bowel transit time was 261 minutes (238-434). The entire small bowel was visualized through capsule endoscopy in 17 cases (80.95%). The histopathologic findings and capsule endoscopy findings resulted in the diagnosis of GvHD in 17 and 16 cases, respectively. There was agreement between the histopathologic and capsule endoscopy findings in 18 cases (15 positive and 3 negative). Sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic yield of capsule endoscopy were 88%, 75%, 94%, 60%, and 85%, respectively.ConclusionsCapsule endoscopy is a safe tool for the diagnosis of GvHD, with high sensitivity and positive predictive value, as well as moderate agreement with histopathologic findings.  相似文献
