Introducción: el parasitismo intestinal, generalmente asintomático pero con repercusiones importantes a nivel socioeconómico y de salud, afecta principalmente a la población infantil en condiciones sa-nitarias deficientes. Se describen prevalencias a nivel nacional de este mayores al 80%, con predominio de protozoos. Objetivo: describir la situación de parasitismo intestinal en preescolares de un hogar infantil estatal de Popayán (Colombia) y su relación con variables sociodemográficas. Materiales y métodos: se realizó un estudio descriptivo de corte transversal, entre mayo y septiembre de 2013, en 187 niños de 1 a 5 años de edad, matriculados en un hogar infantil estatal de Popayán (Colombia). Se realizó una encuesta sociodemográfica y análisis parasitológico de muestras de materia fecal mediante examen directo y método de concentración modificado de Ritchie-Frick. Se calcularon prevalencias, distribuciones de frecuencia y asociaciones de factores sociodemográficos con la presencia de parasitismo intestinal utilizando regresiones logísticas. Resultados: se identificó una prevalencia de parasitismo intestinal de 43,3%. La especie encontrada con mayor frecuencia fue Blastocystis spp. (24,6%), seguida por Entamoeba coli (13,4%) y Giardia intestinalis (11,8%). En ninguna de las muestras se observaron helmintos. Conclusiones: la prevalencia encontrada de parasitismo intestinal se aproxima al promedio nacional, de acuerdo con reportes para población preescolar en otros municipios del país. La ausencia de helmintos y el predominio de especies de protozoos respaldan la necesidad de futuras investigaciones que permitan conocer la epidemiología local. Además, se identificaron condiciones sociodemográficas de riesgo para infecciones en la población estudiada, algunas de ellas asociadas a la presencia de protozoos intestinales.

<p><strong>Introducción:</strong> Las parasitosis intestinales a nivel mundial son un problema de salud pública que afecta a los países en las zonas tropicales. Un grupo muy vulnerable a padecer este tipo de infección son los niños. El objetivo de la presente investigación fue determinar la prevalencia general de parásitos intestinales en las Unidades Educativas de Ciudad Bolívar, entre los años 2009 - 2013. <strong>Materiales y Métodos:</strong> Fueron obtenidos los trabajos de grado sobre el tema del Departamento de Parasitología y Microbiología y así se recolectaron datos sobre edad, sexo, tipo de parasito, especies y asociaciones parasitarias y poder calcular así dicha prevalencia general. <strong>Resultados:</strong> Se encontró una prevalencia general de 63,1% sin predilección por la edad o sexo. Los tipos de parásitos más prevalentes fueron los protozoarios con 83,5%. Las especies más prevalentes fueron Blastocystis spp con 39,7%, Entamoeba coli con 15,3%, y Giardia intestinalis con 13,4%. Las asociaciones parasitarias más frecuentes Blastocystis spp con Endolimax nana (21,1%) y Blastocystis spp con Entamoeba coli. (7,4%). <strong>Discusión:</strong> Los resultados de este estudio guardan relación con estudios realizados a nivel nacional como internacional, con respecto a las prevalencias de parasitosis, el predominio de protozoarios sobre helmintos en los últimos años, y la indistinción de la infección parasitaria con respecto al género. <strong>Conclusiones:</strong> La prevalencia aquí estudiada a manera general es alta, se recomienda seguir haciendo este tipo de estudios en escuelas para denotar el impacto de estas infecciones en niños y la consecuencia que esto conlleva.  </p><p><strong><em>Cómo citar este artículo:</em></strong><em> Nastasi JA</em><em>. </em><em>Prevalencia de parasitosis intestinales en unidades educativas de Ciudad Bolívar, Venezuela.<strong> </strong></em><em>Rev Cuid. 2015; 6(2):1077-84.</em><em> </em><em><span style="text-decoration: underline;"><a href="http://dx.doi.org/10.15649/cuidarte.v6i2.181">http://dx.doi.org/10.15649/cuidarte.v6i2.181</a></span></em><em></em></p>

Stool samples from 122 children from urban slum (n = 72) and rural (n = 50) areas were analyzed using multi-parallel real-time qPCR to determine the prevalence of intestinal parasites from two communities in Colombia. Findings indicated a prevalence of 86.1% Blastocystis spp., 62.5% Giardia intestinalis, 19.4% Cryptosporidium spp., 19.4% Ascaris lumbricoides, and 5.6% Trichuris trichiura in an urban slum; and 76% Blastocystis spp., 68% Giardia intestinalis, 20% Entamoeba histolytica, 50% Ascaris lumbricoides, 46% Trichuris trichiura and 2% Strongyloides stercoralis in rural areas. Polyparasitism was higher in rural (58%) compared to urban (25%) areas (p = 0.001). Trichuris trichiura burden was higher in the rural area (p = 0.002). Over 40% of helminth infections in rural areas had a heavy parasite burden by WHO classification. Over half of urban and rural children were infected with Giardia intestinalis and Blastocystis spp. Our data provides accurate epidemiologic surveillance for public health interventions.

Objetivos: Determinar la presencia de parásitos en Moscas de la Comunidad Shipiba de Cantagallo, Lima-Perú 2014. Materiales y métodos: Estudio transversal descriptivo, realizado en el Instituto de Medicina Tropical Daniel Alcides Carrión, Universidad Nacional Mayor de San Marcos. Se usó una muestra de 1260 ejemplares de Moscas. Muestreo no  probabilístico por conveniencia dividido en dos grupos: enjuagado y machacado. Se realizaron las técnicas de enjuagado y machacado de moscas; los sedimentos se analizaron con lugol utilizando microscopios ópticos a un aumento de 400x por campo. Se dispuso de una hoja de recolección de datos donde se codificó la muestra analizada, además se señaló la presencia de los diferentes entero-parásitos según la epidemiología nacional y estudios realizados en distritos locales. Resultados: Se hallaron los determinados porcentajes de acuerdo a la unidad de análisis. En el enjuagado: Entamoeba coli (35%), Blastocystis spp. (30%), Complejo Entamoeba spp. (15%), Endolimax nana (15%), Chilomastix mesnili (10%) y Ciclospora cayetanensis (10%); en relación al machacado se encontró: Entamoeba coli (75%), Blastocystis spp. (10%), Entamoeba spp. (50%), Endolimax nana (5%), Chilomastix mesnili (5%) y Giardia intestinalis (10%). Conclusiones: Se detectó un gran porcentaje de Entamoeba coli tanto en el enjuagado como en el machacado, seguido de Complejo Entamoeba spp.; ambos causantes de infecciones gastrointestinales, por ello debemos insistir en el papel de Moscas como transmisor de enfermedades en poblaciones similares a la Comunidad Shipiba Cantagallo.

Blastocystis Spp

Intestinal parasites are a problem for public health all over the world. The infection with Blastocystis, a protozoan of controversial pathogenicity, is one of the most common among them all. In this study, the occurrence of intestinal parasites, with emphasis on Blastocystis, in patients at the Universidade Federal do Triângulo Mineiro was investigated in Uberaba (MG) through microscopy of direct smears and fecal concentrates using Ritchie’s method. Feces of 1,323 patients were examined from April 2011 to May 2012. In 28.7% of them at least one intestinal parasite was identified, and the most frequent organisms were Blastocystis spp. (17.8%) and Giardia intestinalis (7.4%). The occurrence of parasitism was higher in children aged 6 -10 years old, and the infection with Blastocystis spp. was higher above the age of six (p < 0.001). The exclusive presence of G. intestinalis and of Blastocystis spp. was observed in 5.4% and 12.2% of the patients, respectively. Regarding patients with diarrheic feces, 8% revealed unique parasitism of Blastocystis spp. Other intestinal parasites observed in children were Ascaris lumbricoides (0.3%) and Entamoeba histolytica/dispar/moshkovskii (1.4%). The Ritchie’s method was more sensitive (92.8%) when compared to direct microscopy (89.8%), with high agreement between them (97.7%, kappa = 0.92). In conclusion, the occurrence of Blastocystis spp. in Uberaba is high and the presence of diarrheic feces with exclusive presence of the parasite of Blastocystis spp. was observed.

In addition to the classical pathogens, which are well understood and well identified, new pathogens with the potential to spread epidemiologically are being identified. Some of these little-known organisms are the simplest Blastocystis spp. blastocystostosis. The clinical significance of Blastocystis spp. and its pathogenicity are still under discussion. This parasite belongs to a group of single-celled eukaryotic organisms living in the colon of the human intestine. Blastocystis spp. is known to be found both in people with reduced immune status and in individuals without any clinical manifestation. It has been established that a sufficiently high degree of invasiveness is observed in persons with gastrointestinal tract diseases, dermatosis, allergic reactions, in patients with carriers of the human immunodeficiency virus, etc. Possessing persistence factors, protozoa blastocysts contribute to the inactivation of host defensive mechanisms, providing a stable anthogonistic effect. In recent years, many works have been devoted to the characteristics of the persistent properties of Blastocystis spr., however, individual properties of blastocysts, in particular, anticytokine activity (ACA), have not yet been studied. In this regard, the work studied the anticytokine activity of microorganisms isolated from healthy subjects and patients with gastrointestinal tract diseases. A high prevalence of the studied characteristic in the subjects was shown. The expression of anticytokine activity in the obtained isolates of blastocysts was the highest in the group of persons with gastric ulcer disease, which decreased in the order of duodenal ulcer, chronic cholecystitis, chronic gastritis, etc. The data obtained in this work on the high level of ACA expression in blastocyst isolates obtained from individuals with gastrointestinal diseases as compared with the control group enables to conclude that their exometabolites may influence the local cytokine balance [1], which supports the inflammatory process.

Background: Diarrhea is a leading cause of morbidity and mortality in children in developing countries. Rotavirus is the most important factor cause of severe diarrhea and mortality in children, especially under 2 years. Objective: To study Clinical and paraclinical characteristitics of rotavirus diarrhea in children less than 5 years old in the Pediatric Department of Binh Dinh General Hospital. Methods: Cross observational study, 417 children from 2 months to 5 years old who were hospitalized for acute diarrhea without blood in stool in Pediatric Department of Binh Dinh general hospital, from 15/3/2012 to 14/3/2013. There were 228 patients with rotavirus - positive stool specimens and 189 patients with rotavirus - negative stool specimens. Tested for rotavirus A classification by agglutination techniques. Results: Percentage of Rotavirus diarrhea in children <5 years was 54.7%. The mean age of rotavirus diarrhea was 14.83 ± 9.08 tháng months. Ages with the highest cases of rotavirus diarrhea are 2 - 12 months: 48.2%. Rotavirrus diarrhea is experienced in every month but, the highest prevalence is experienced in the spring - summer) with 71,5%. Clinical characteristitics of rotavirus diarrhea: Vomit presents in 91,7% of cases. 32.9% of the initial symptoms of the disease is vomiting. Mean number of vomiting episodes per day: 7 ± 3.57 times, significantly higher compared with non-rotavirus acute diarrhea (p <0,01). Mean number of bowel movement per day: 10.61±4.18 times, mean duration of diarrhea: 6.66 ± 2.52 days. Younger children have higher frequency and duration of diarrhea compared to older children. Paraclinical characteristitics of rotavirus diarrhea: the mean number leukocyte: 9.74 ±3.61 (x 109/l). 2.2% with low blood sodium status; 8.8% with reduction in serum potassium concentration. 26.3% with low blood calcium and glucose status. Laboratory characteristics of stool: 8.8% with white blood cells in stool, 41.7% with carbohydrate in stool. Conclusion: Rotavirus accounting for 54.7% of the causes of diarrhea in children. Rotavirus diarrhea is experienced throughout the year but the highest prevalence is in the spring-summer. Prominent symptoms of the disease are vomiting and watery stool. Children <24 months experience higher frequency and duration of diarrhea compared to older age groups. Key words: Diarrhea, Rotavirus.
