    Acanthamoeba 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.

    Determinación de la Actividad Acanthamoebicida In Vitro del Aceite de Myrcianthes leucoxyla sobre Tres Aislados Ambientales de la Ciudad de Cúcuta, Norte de Santander en 2022

    Acanthamoeba spp es una ameba de vida libre (AVL) que suele habitar en una gran variedad de ambientes como lo son; el agua, aire y suelo, presenta dos estadios morfológicos; el quiste y trofozoíto siendo el quiste la forma infectiva y de resistencia y el trofozoíto la forma infecciosa, además se ha demostrado que esta ameba (Acanthamoeba spp) causa enfermedades graves como lo es la encefalitis amebiana granulomatosa y la queratitis amebiana, es por ello que el presente trabajo de grado se centró en determinar la actividad acanthamoebicida que tiene el aceite de Myrcianthes leucoxyla sobre Acanthamoeba spp representados en 3 aislados ambientales. Para llevar a cabo la investigación de tipo explicativo con un diseño de investigación de campo; a partir de tres aislados ambientales cultivados en agar no nutritivo se revisó la mortalidad y supervivencia de Acanthamoeba spp frente al aceite de Myrcianthes leucoxyla mediante el test de viabilidad celular de azul de tripano, obteniéndose como resultados la presencia de Acanthamoeba spp en una piscina, en el lago del parque del agua y pozo senderos; por lo cual se procedió a demostrar la actividad acanthamoebicida del aceite Myrcianthes leucoxyla en los aislados ambientales exponiéndolas a diferentes concentraciones (desde 25mg/ml) de aceite de M. leucoxyla. Se pudo determinar gracias a esta investigación que la concentración 200 mg/ml (CL50) es letal para esta ameba. En conclusión, este estudio permite demostrar la actividad que tiene el aceite Myrcianthes leucoxyla frente Acanthamoeba spp siendo así un aporte interesante para seguir siendo estudiada ya que es una planta nacional que puede facilitar la desinfección y prevención sobre este tipo de amebas.

    Endosimbiosis entre acanthamoeba spp y cryptococcus spp. En muestras ambientales de la ciudad de CUCUTA, NORTE DE SANTANDER.
    (Cúcuta: Universidad de Santander, 2018, 2018-12-12) Tarazona Gutierrez, Danna Franchesca.; Vega Galvis, Diana Gabriela.; Contreras Rangel, Jael.; Ríos Ramírez, Yesmit-Karina.
    Acanthamoeba spp. and Cryptococcus spp. they are opportunistic pathogens, ubiquitous in nature. Many species of Acanthamoeba spp. they are responsible for fatal diseases for humans such as: meningoencephalitis and keratitis, so the study of their endosymbiotic interaction is representative. The purpose of the study was to establish the endosymbiosis between Acanthamoeba spp. and Cryptococcus spp. in environmental samples from the city of Cúcuta, Norte de Santander. A descriptive study was carried out, collecting a total of 132 samples, 120 of soils from four parks in the city of Cúcuta, Norte de Santander: Colón Park, Santander Park, San Eduardo Park, Erasmo Meoz University Hospital Park and 12 water samples taken from the Pamplonita River and the Bogotá Wastewater Canal. The culture was carried out on non-nutritive agar plates previously seeded with inactive Escherichia coli ATCC 25922. Acanthamoeba spp. it was isolated from 83 (70%) of the soil samples and 12 (100%) of the water samples. Also, the identification of Cryptococcus spp. as an endosymbiont, it was present in 7 (5.8%) of the strains samples of Acanthamoeba spp.

    Presencia de amebas de vida libre y bacterias endosimbioticas en agua de consumo de los municipios de PAMPLONA y de VILLA DEL ROSARIO.
    (Cúcuta: Universidad de Sántander, 2018, 2018-06-25) Jimenez Garza, Marlen Andrea.; Bermon Martinez, Maria Fernanda.; Ríos Ramírez, Yesmit-Karina.; Contreras Rangel, Jael.
    Free living amoeba (FLA) are protozoa that are widely distributed in the environment, in fact they are distributed in soils, waters, air conditioners, swimming pools, etc. These microorganisms can develop severe pathologies in humans, mainly due to their various mechanisms of resistance, these pathologies range from courses of serious infections such as primary amoebic meningoencephalitis and granulomatous amebic encephalitis to milder cases such as amoebic keratitis. In reference to the resistance of these microorganisms we have an important factor to highlight as the temperature, since these have a capacity to withstand high temperatures. On the other hand, these microorganisms also have the ability to have an interaction with fungal viruses and bacteria called endosymbiosis, these AVL, in addition to feeding on these microorganisms, give them protection from being digested by them, in addition to external factors and increase in virulence capacity, constituting a Public Health problem. That said, the objective was to determine the presence of free-living amoebas and endosymbiotic bacteria in drinking water in the municipalities of Pamplona and Villa del Rosario.
