OBJECTIVE: To determine the presence of Acanthamoeba genus in several Ica city (south of Lima) water sources. MATERIAL AND METHODS: Thirty-one samples from 7 natural water sources (lagoons) and 24 artificial sources (wells, tanks for rehabilitation therapy, reservoirs and cisterns) were examined dur...

MATERIAL AND METHODS: Thirty-one samples from 7 natural water sources (lagoons) and 24 artificial sources (wells, tanks for rehabilitation therapy, reservoirs and cisterns) were examined during May 1997 in several points of the city. Samples were sowed in Agar Myast and in Agar Napolitan, incubated at 37°C and checked after 10 days. Positive samples were inoculated to immunocompetent mice by intranasal route; resultant lesions were cultured again following the same procedure. RESULTS: In 11 samples (35,5%) Acanthamoeba cysts were isolated, 6 from natural sources and 5 from artificial sources; among negative samples only one came from natural source and the other 19 came from artificial sources inside homes or from the local hospital. OR =22,8 was obtained for exposition to natural sources of water, as cause of infection (confidence limit 95% 1,83-642,55, X2 =7,83). CONCLUSIONS: Presence of Acanthamoeba genus is more frequent in natural water sources at Ica city. Further studies are necessary to confirm this situation.OBJETIVO: Determinar la presencia del género Acanthamoeba en diversas fuentes de agua, en la ciudad de Ica, al sur de Lima. MATERIAL Y MÉTODOS: Se examinó 31 muestras de 7 fuentes de aguas naturales (lagunas) y 25 artificiales (pozos, tanques para terapia de rehabilitación, reservorios y cisternas) durante mayo de 1997, en diversos puntos de la ciudad de Ica. Las muestras fueron sembradas en Agar Myast y en Agar Napolitano, incubadas a 37°C y observadas a los 10 días. Las muestras positivas fueron inoculadas en ratones inmunocompetentes por vía intranasal, las lesiones producidas fueron cultivadas nuevamente siguiendo el mismo procedi- miento. RESULTADOS: De las 31 muestras revisadas, en 11 (35,5%), se observó quistes de Acanthamoeba, 6 fueron aisladas de fuentes naturales y 5 de fuentes artificiales, mientras que entre las muestras negativas sólo una provino de fuente natural y las otras 19 provinieron de aguas artificiales intradomiciliarias o del hospital local. Estos resultados permiten obtener un OR =22,8 para la exposición de fuentes naturales de agua, como causante de la infección (límite de confianza 95% 1,83-642,55, X2 =7,83). CONCLUSIONES: La presencia del género Acanthamoeba es más frecuente en fuentes de agua naturales en la ciudad de Ica, aunque es necesario realizar un estudio de mayor cobertura para confirmar esta situación.Universidad Nacional Mayor de San Marcos, Facultad de Medicina Humana2002-06-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/anales/article/view/148710.15381/anales.v63i2.1487Anales de la Facultad de Medicina; Vol. 63 No. 2 (2002); 101-105Anales de la Facultad de Medicina; Vol. 63 Núm. 2 (2002); 101-1051609-94191025-5583reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/anales/article/view/1487/1266Derechos de autor 2002 ROXANA SUÁREZ, YRMA ESPINOZA, CARMEN VILLANUEVA, JOSÉ RAMOS, PEDRO HUAPAYA, RENZO MARQUINAhttps://creativecommons.org/licenses/by-nc-sa/4.0info:eu-repo/semantics/openAccessoai:ojs.csi.unmsm:article/14872020-04-14T19:00:40Z
