- PublicaciónRestringidoAcanthamoeba SPP como hospedero de helicobacter pylori en diferentes tipos de agua de SAN JOSE DE CÚCUTA, NORTE DE SANTANDER, 2018-2019(Cúcuta: Universidad de Santander, 2019, 2019-10-22) Bautista, Maria Fernanda.; Espinel Leal, Maria Fernanda.; Ríos Ramírez, Yesmit-Karina.; Contreras Rangel, Jael.The amoebae of free life are cosmopolitan protozoa that are found in humid environments such as soil and water, being the most common that they are found in water sources, whether they are sweet or salty but most prevalent in stagnant waters. Among the free-living amoebas that have a pathogenic capacity for man, those of the genus Acanthamoeba spp and Naegleria spp stand out, and Acanthamoeba spp also has an endosymbiotic role of great relevance with other mainly pathogenic microorganisms. As is Helicobacter pylori which is a gram-negative, spiral-shaped and mobile gram bacillus that is colonizing the stomach of approximately half of the world's population, it has been linked as the causative agent of chronic diseases such as gastritis but in greater relevance with gastric cancer.
- PublicaciónRestringidoPrevalencia de infección por Helicobacter pylori y Hallazgos histopatológicos en un centro de referencia de Valledupar(Valledupar : Universidad de Santander, 2019, 2019-06-13) Lubo Vanegas, Rubén Darío; Páez González, Esmeralda Leonor; Fragoso Amaya, Elia-Mercedes; Molina Campo, Diana-CenobiaHelicobacter pylori is a gram negative bacterium that is able to colonize the gastric mucosa of humans and produce the most prevalent chronic infection in the world mainly in developing countries, relating to pathologies ranging from acute gastritis to gastric cancer. In this research work, the prevalence of Helicobacter pylori infection and histopathological findings were established by analyzing the results of biopsies processed at a reference center in Valledupar. It is a retrospective descriptive study where the study population corresponded to 983 patients who attended a pathology center in Valledupar who, between 2015 - 2017, had a diagnostic test for Helicobacter pylori and histopathological studies. The overall prevalence of Helicobacter pylori infection in the period studied was 42.5%, with a higher number of patients observed in 2017 but the prevalence was higher in 2016 with 44.1%. The highest number of cases occurred in female patients with 25.3%. For the male sex it was 17.2%. The age range with the highest prevalence was 40-49 years with 60%. Regarding histopathological findings, Helicobacter pylori occurred in 27.1% of patients with chronic gastritis, in 9.9% with acute gastritis, in 4.5% with findings associated with malignancy, in 0.3% with normal findings and in 0.9%. With other findings.
