Prevalencia de parasitosis intestinal en trabajadores de la florícola Irose de la provincia de Pichincha ­ Cantón Pedro Moncayo 2019 / Prevalence of intestinal parasitosis in workers of the irose florícola of the province of pichincha - Canton Pedro Moncayo

Las infecciones por parásitos intestinales son de ocurrencia constantes y se encuentran asociadas al incumplimiento de las medidas sanitarias por parte de la población. El objetivo de esa investigación fue establecer la prevalencia de parasitosis intestinal por protozoos y helmintos en trabajadores de la florícola iRose de la provincia de Pichincha-Cantón Pedro Moncayo mediante el examen coproparasitario realizado en el mes de agosto de 2019. Correspondió a un estudio transversal, descriptivo y de tipo observacional. La población estuvo integrada por 88 personas, quienes son trabajadores de la florícola iRose, Provincia de Pichincha, cantón Pedro Moncayo, distribuidos de la siguiente manera: 49 trabajadores del sexo masculino y 39 trabajadores del sexo femenino. La técnica de recolección de datos utilizada fue la encuesta y la observación directa y luego de obtener las muestras biológicas, la detección de parásitos intestinales se realizó mediante el método de coproparasitario en muestras heces. Los resultados evidencian presencia de protozoos en un 92.5% de las muestras estudiadas, mientras que el 7.5% presentan helmintos; mientras que el 40% de los estudios revelan quistes de endolimax nana, detectándose en el 25% de la muestra de los trabajadores de sexo masculino y con una presencia del 15% en los trabajadores del sexo femenino. Por lo que se recomienda realizar el examen coproparasitario al menos dos veces al año y paralelamente fortalecer las estrategias de promoción y prevención(AU)

Infections with intestinal parasites are of constant occurrence and are associated with non-compliance with health measures by the population. The objective of this research was to establish the prevalence of intestinal parasitosis by protozoa and helminths in la workers IRose flower farm of the province of Pichincha-Canton Pedro Moncayo through the coproparasitario examination carried out in august 2019. It corresponded to a cross-sectional, descriptive, observational study. The population was composed of 88 people, who are workers of the floricultural iRose, Province of Pichincha, canton Pedro Moncayo, distributed as follows: 49 male and 39 female workers. The data collection technique used was survey and direct observation and after obtaining biological samples, detection of intestinal parasites was performed using the coproparasitario method in fecal samples. The results showed the presence of protozoa in 92.5% of the samples studied, while 7.5% showed helminths; while 40% of studies reveal endolimax nana cysts, being detected in 25% of the sample of male workers and with a presence of 15% in female workers. Therefore, it is recommended to perform the coproparasitario examination less twice a year and in parallel strengthen strategies promotion and prevention(AU)

Contaminación enteroparasitaria de intercomunicadores en edificios de Barquisimeto y Cabudare, Venezuela / Enteroparites contamination of intercoms in buildings of Barquisimeto and Cabudare, Venezuela

Resumen Introducción. La falta de estudios en intercomunicadores como medios de propagación de enteroparásitos en Venezuela, motivó el presente estudio. Metodología. Se frotó el intercomunicador tres veces con un hisopo impregnado con solución salina 0,85% (SSI), resuspendiéndolo en un tubo con 10 ml de SSI, el cual se centrifugó a 3000 rpm por 10 minutos para luego observar el sedimente al microscopio. Resultados. El 65% de las muestras estuvieron contaminadas, encontrando 10 taxones de enteroparásitos, a saber: Blastocystis sp (49% del total de muestras examinadas), Endolimax nana (36%), lodamoeba butschlii (8%), Giardia lamblia (7%), Entamoeba coli (4%), Chilomastix mesnili (2%), Entamoeba hartmanni (2%), Trichuris trichiura (2%), Hymenolepis nana (2%) y Taenia sp (1%). Discusión. La diversidad de parásitos encontrados y su abundancia, se corresponden con lo reportado en poblaciones de la misma zona. Conclusión. La falta de higiene en la mayoría de los intercomunicadores facilitan el potencial de estos para transmitir los parásitos endémicos del estado Lara.

Abstract Introduction. The lack of studies in intercoms as means of propagation of enteroparasites in Venezuela, motivated the present study. Methodology. The intercom was rubbed three times with a swab impregnated with 0.85% saline solution (SSI), resuspending it in a tube with 10 ml of SSI, which was centrifuged at 3000 rpm for 10 minutes to then observe the pellet under a microscope. Results. 65% of the samples were contaminated, finding 10 taxa of enteroparasites, namely: Blastocystis sp (49% of the samples examined), Endolimax nana (36%), Iodamoeba butschlii (8%), Giardia lamblia (7%), Entamoeba coli (4%), Chilomastix mesnili (2%), Entamoeba hartmanni (2%), Trichuris trichiura (2%), Hymenolepis nana (2%) and Taenia sp (1%). Discussion. The diversity of parasites found and their abundance correspond to that reported in populations of the same area. Conclusion. The lack of hygiene of most of the intercoms facilitates the potential of these to transmit the endemic parasites of the Lara State.

Prevalence of Intestinal Protozoans among Schoolchildren in Suburban Areas near Yangon, Myanmar

Although intestinal protozoans are common etiologies of diarrhea, few studies have been conducted in Myanmar. This study planned to investigate the prevalence of Giardia lamblia, Entamoeba coli, Entamoeba histolytica, and Endolimax nana among schoolchildren and their guardians in suburban areas near Yangon, Myanmar. We performed a cross-sectional survey among schoolchildren and their guardians from 7 primary schools in South Dagon and Hlaing Thar Yar districts, Yangon, Myanmar. Stool samples were observed with a microscope after concentration technique and iodine staining. Total 821 stool samples, including 556 from schoolchildren and 265 from guardians, were examined. The median age was 6 years old for schoolchildren and 36 years old for guardians. A 53.1% of the school children and 14.6 % of the guardians were males. The overall prevalence of each intestinal protozoan species was as follows: 3.4% (28/821) for G. lamblia; 3.5% (29/821) for E. coli; 1.2% (10/821) for E. histoytica, and 3.0% for E. nana. This study showed that intestinal protozoans are common in primary schoolchildren and their guardians in suburban areas near Yangon, Myanmar. Health interventions, such as hand washing education, improvement of sanitation, and establishment of water purification systems are urgently needed in this area.
