    Co-Authors: Bracho Ángela, Rivero Zulbey, Banquet Kely, Sánchez Fabiana, Corzo Ivanna, Atencio Ricardo, Villalobos Rafael
    Abstract:

    Intestinal parasitosis are widely distributed in the world, constituting a public health problem. To evaluate whether the geographical and ecological conditions of the island municipality Almirante Padilla of Zulia State influence the prevalence of intestinal parasitosis of its inhabitants, 87 fecal samples corresponding to individuals of any age and sex were analyzed. Each sample was subjected to direct coproparasitological methods (SSF 0.85% and lugol), formalin-ether concentration method (Ritchie), Kinyoun stain and agar plate technique (Arakaki) for recovery and diagnosis Strongyloides stercoralis larvae. The prevalence of intestinal parasites in the study population was 50.57% (44/87), which prevailed monoparasitism with 52.27% (23/44). Among the parasitized individuals, 29.89% (26/87) of cases corresponded to Chromista Blastocystis sp., followed by Entamoeba  complex (13.79%), Endolimax Nana (13.79%) and Ascaris lumbricoides (13,79%). Strongyloides stercoralis or intestinal coccidia was not detected. The age group most affected were children aged 2 to 6 years of age (p <0.05). The prevalence and variety of intestinal parasites detected is similar to that reported for other areas of Zulia state where sanitary conditions are similar.Las parasitosis intestinales están ampliamente difundidas en el mundo, constituyendo un problema de salud pública. Para evaluar si las condiciones geográficas y ecológicas del municipio insular Almirante Padilla del estado Zulia influyen en la prevalencia de parasitosis intestinales de sus habitantes, se analizaron 87 muestras fecales, correspondientes a individuos de cualquier edad y sexo. Cada muestra fue sometida a métodos coproparasitológico directos (con SSF 0,85% y lugol), método de concentración formol-éter (Ritchie), coloración de Kinyoun y técnica de agar en placa (Arakaki) para la recuperación y diagnóstico de larvas de Strongyloides stercoralis. La prevalencia de enteroparásitos en la población estudiada fue de 50,57% (44/87), donde predominó el monoparasitismo con 52,27% (23/44). Entre los individuos parasitados, el 29,89% (26/87) de los casos correspondieron al chromista Blastocystis sp., seguido de los protozoos pertenecientes al complejo Entamoeba,Endolimax Nana (13,79% c/u) y Ascaris lumbricoides (13,79%). No se detectó Strongyloides stercoralis ni coccidios intestinales. El grupo etario más afectado fueron los niños de 2 a 6 años de edad (p<0,05). La prevalencia y variedad de enteroparásitos detectada es parecida a la referida para otras zonas del estado Zulia con condiciones higiénico-sanitarias similares

    Abstract:

    Resumen: Con la finalidad de determinar la prevalencia de Blastocystis sp. y especies de protozoarios comensales intestinales del hombre según diferentes aspectos como la edad y el sexo, se evaluaron muestras de heces de 111 individuos varones y mujeres de todas las edades, pobladores de Santa Rosa de Agua, Maracaibo, estado Zulia. Cada muestra fecal se analizó a través de un examen al fresco, tinción de lugol y técnica de concentración de Ritchie. Se utilizó la tinción de hematoxilina férrica para identificar trofozoitos de Dientamoeba fragilis. Las especies del complejo Entamoeba histolytica/Entamoeba dispar se diferenciaron mediante técnicas de PCR. Blastocystis sp. fue la especie predominante (45,6%), seguida por Entamoeba coli (17,9%), Endolimax Nana (14,8%), Chilomastix mesnili (6,2%), Entamoeba dispar (5,6%), Dientamoeba fragilis, Pentatrichomonas hominis, Iodamoeba butschlii (3,1%) respectivamente y Entamoeba hartmanni (0,6%). Hubo afinidad parasitaria entre las especies Entamoeba coli y Endolimax Nana. No se demostró asociación entre presencia de infección y sexo. Los grupos etarios preescolares y escolares demostraron asociación significativa con la infección parasitaria. Se determinó una elevada prevalencia de Blastocystis sp. y especies comensales intestinales, todas indicadoras de contaminación fecal, donde probablemente factores ambientales y socioculturales promovieron su transmisión.Prevalence of Blastocystis sp. and other commensal protozoa in individuals from Santa Rosa del Agua, Zulia State Abstract: With the purpose of determining Blastocytis sp. and other commensal intestinal protozoa species prevalence according to different aspects such as age and sex, we evaluated 111 feces samples from male and female individuals of all ages, living at Santa Rosa del Agua, Maracaibo, Zulia State, Venezuela. Each fecal sample was analyzed fresh, stained with lugol, and by Ritchie’s concentration test. We used ferric hematoxilin stain to identify Dientamoeba fragilis trophozoites. Species belonging to the Entamoeba histolytica/Entamoeba dispar complex were differentiated through PCR techniques. Blastocytis sp. was the predominant species (45.6%), followed by Entamoeba coli (17.9%), Endolimax Nana (14.8%), Chilomastix mesnili (6.2%), Entamoeba dispar (5.6%), Dientamoeba fragilis, Pentatrichomonas hominis, Iodamoeba butschlii (3.1%, respectively), and Entamoeba hartmanni (0.6%). There was parasitic affinity between the Entamoeba coli and Endolimax Nana species. There was no association between presence of infection and sex. Pre-school and school age groups showed a significant association with parasite infection. A high prevalence of Blastocystis sp. and intestinal commensal species was determined, all indicative of fecal contamination, where environmental and sociocultural factors probably promote transmission

    'Instituto Nacional de Salud (Colombia)', 2013
    Co-Authors: Rivero Zulbey, Bracho Ángela, Hernández Amparo, Salazar Solneumar, Villalobos Rafael
    Abstract:

    Objective: To detect the presence of microsporidia and other enteric parasites in patients with HIVAIDS of the Autonomous Services University Hospital of Maracaibo (SAHUM), where there are no previous studies in this field.Materials and methods: Fecal samples were analyzed by means of direct exam, concetration method with formal-ether, Kinyoun coloration and fast Gram-Chromotrope coloration. Separate PCR were perfomed to differentiate Entamoeba histolytica and Entamoeba dispar, when the E. histolytica/E. dispar complex was observed in the microscope. Information on the patient was obtained trough clinical history.Results: Of 56 individuals that participated, 38 (67.86%) presented some commensal parasite and/or pathogenic species in their fecal sample. Carriers of pathogenic species were predominat (26/38). Protozoa such as Isospora belli protozoa (17.65%), Blastocystis spp. (17.65%), Cryptosporidium spp. (7.84%), E. histolytica/E. dispar (5.88%), Entamoeba coli (3.92%), Giardia lamblia (3.92%), Endolimax Nana (3.92%), Cyclospora cayetanensis (3.92%), and Chilomastix mesnilli (1.96%) were diagnosed. Among the helminths, Ascaris lumbricoides, Trichuris trichiura and Strongyloides stercoralis, had a percentage of 27.27% each, and Hymenolepis Nana, 18.18%. Entamoeba histolytica was only detected in one of three cases presenting complex microscopic examination. By Gram-chromotrope, 17 samples showed spores of the Microsporidia phylum, equivalent to 33.33% prevalence.Conclusion: Microsporidia may be first prevalente in HIV positive patients when specific diagnostic techniques are used. doi: http://dx.doi.org/10.7705/biomedica.v33i4.1468Introducción. Desde 1985, los microsporidios se consideran parásitos causantes de infecciones emergentes y oportunistas en individuos inmunocomprometidos en todo el mundo.Objetivo. Detectar la presencia de microsporidios y otros enteroparásitos en pacientes con VIH/sida del Servicio Autónomo Hospital Universitario de Maracaibo (SAHUM), donde no existían estudios previos en este campo.Materiales y métodos. Las muestras fecales se analizaron mediante examen directo, método de concentración con formol-éter, coloración de Kinyoun y coloración Gram-cromotropo rápida. Se realizaron PCR separadas para diferenciar Entamoeba histolytica o Entamoeba dispar, cuando se observó el complejo E. histolytica/dispar al microscopio. Mediante historia clínica se obtuvo información del paciente.Resultados. De los 56 individuos participantes, 38 (67,86 %) presentaron alguna especie parasitaria comensal o patógena en su muestra fecal. Predominaron los individuos portadores de especies parásitas patógenas (26/38). Fueron diagnosticados protozoos como Isospora belli (17,65 %), Blastocystis spp. (17,65 %), Cryptosporidium spp. (7,84 %), complejo Entamoeba histolytica/dispar (5,88 %), Entamoeba coli (3,92 %), Giardia lamblia (3,92 %), Endolimax Nana (3,92 %), Cyclospora cayetanensis (3,92 %) y Chilomastix mesnili (1,96 %). Entre los helmintos, Ascaris lumbricoides, Trichuris trichiura y Strongyloides stercoralis, presentaron un porcentaje de 27,27 % cada uno, e Hymenolepis Nana, de 18,18 %. Solo se detectó E. histolytica en uno de los tres casos que presentaron el complejo al examen microscópico. Mediante Gram-cromotropo, 17 muestras evidenciaron esporas del filo Microsporidia, lo que equivale a un 33,33 % de prevalencia.Conclusión. Los microsporidios pueden ocupar el primer lugar de prevalencia en pacientes con VIH positivo, cuando se utilizan técnicas diagnósticas específicas. doi: http://dx.doi.org/10.7705/biomedica.v33i4.1468

Desde 1985, los microsporidios se consideran parásitos causantes de infecciones emergentes y oportunistas en individuos inmunocomprometidos en todo el mundo.Objetivo. Detectar la presencia de microsporidios y otros enteroparásitos en pacientes con VIH/sida del Servicio Autónomo Hospital Universitario de Maracaibo (SAHUM), donde no existían estudios previos en este campo.Materiales y métodos. Las muestras fecales se analizaron mediante examen directo, método de concentración con formol-éter, coloración de Kinyoun y coloración Gram-cromotropo rápida. Se realizaron PCR separadas para diferenciar Entamoeba histolytica o Entamoeba dispar, cuando se observó el complejo E. histolytica/dispar al microscopio. Mediante historia clínica se obtuvo información del paciente.Resultados. De los 56 individuos participantes, 38 (67,86 %) presentaron alguna especie parasitaria comensal o patógena en su muestra fecal. Predominaron los individuos portadores de especies parásitas patógenas (26/38). Fueron diagnosticados protozoos como Isospora belli (17,65 %), Blastocystis spp. (17,65 %), Cryptosporidium spp. (7,84 %), complejo Entamoeba histolytica/dispar (5,88 %), Entamoeba coli (3,92 %), Giardia lamblia (3,92 %), Endolimax Nana (3,92 %), Cyclospora cayetanensis (3,92 %) y Chilomastix mesnili (1,96 %). Entre los helmintos, Ascaris lumbricoides, Trichuris trichiura y Strongyloides stercoralis, presentaron un porcentaje de 27,27 % cada uno, e Hymenolepis Nana, de 18,18 %. Solo se detectó E. histolytica en uno de los tres casos que presentaron el complejo al examen microscópico. Mediante Gram-cromotropo, 17 muestras evidenciaron esporas del filo Microsporidia, lo que equivale a un 33,33 % de prevalencia.Conclusión. Los microsporidios pueden ocupar el primer lugar de prevalencia en pacientes con VIH positivo, cuando se utilizan técnicas diagnósticas específicas. doi: http://dx.doi.org/10.7705/biomedica.v33i4.1468

    Abstract:

    Intestinal parasitosis are widely distributed in the world, constituting a public health problem. To evaluate whether the geographical and ecological conditions of the island municipality Almirante Padilla of Zulia State influence the prevalence of intestinal parasitosis of its inhabitants, 87 fecal samples corresponding to individuals of any age and sex were analyzed. Each sample was subjected to direct coproparasitological methods (SSF 0.85% and lugol), formalin-ether concentration method (Ritchie), Kinyoun stain and agar plate technique (Arakaki) for recovery and diagnosis Strongyloides stercoralis larvae. The prevalence of intestinal parasites in the study population was 50.57% (44/87), which prevailed monoparasitism with 52.27% (23/44). Among the parasitized individuals, 29.89% (26/87) of cases corresponded to Chromista Blastocystis sp., followed by Entamoeba  complex (13.79%), Endolimax Nana (13.79%) and Ascaris lumbricoides (13,79%). Strongyloides stercoralis or intestinal coccidia was not detected. The age group most affected were children aged 2 to 6 years of age (p <0.05). The prevalence and variety of intestinal parasites detected is similar to that reported for other areas of Zulia state where sanitary conditions are similar.Las parasitosis intestinales están ampliamente difundidas en el mundo, constituyendo un problema de salud pública. Para evaluar si las condiciones geográficas y ecológicas del municipio insular Almirante Padilla del estado Zulia influyen en la prevalencia de parasitosis intestinales de sus habitantes, se analizaron 87 muestras fecales, correspondientes a individuos de cualquier edad y sexo. Cada muestra fue sometida a métodos coproparasitológico directos (con SSF 0,85% y lugol), método de concentración formol-éter (Ritchie), coloración de Kinyoun y técnica de agar en placa (Arakaki) para la recuperación y diagnóstico de larvas de Strongyloides stercoralis. La prevalencia de enteroparásitos en la población estudiada fue de 50,57% (44/87), donde predominó el monoparasitismo con 52,27% (23/44). Entre los individuos parasitados, el 29,89% (26/87) de los casos correspondieron al chromista Blastocystis sp., seguido de los protozoos pertenecientes al complejo Entamoeba,Endolimax Nana (13,79% c/u) y Ascaris lumbricoides (13,79%). No se detectó Strongyloides stercoralis ni coccidios intestinales. El grupo etario más afectado fueron los niños de 2 a 6 años de edad (p<0,05). La prevalencia y variedad de enteroparásitos detectada es parecida a la referida para otras zonas del estado Zulia con condiciones higiénico-sanitarias similares
