Avaliação parasitológica em amostras de alfaces (Lactuca sativa var. crispa) comercializadas no município de Quatá, São Paulo, Brasil

There is little research on the practices of sanitary inspection in the chain of production of vegetables to the consumer, especially those eaten raw, they are liable to serve microorganism such as bacteria, fungi and parasites, contributing to possible health hazards. The aim of this study was to assess qualitatively contamination by parasites and / or commensals of medical interest in lettuce leaves (Lactuca sativa) fresh market in the municipality of Quata Sao Paulo. A total of 15 random samples were analyzed every other day of the three different places that sell vegetables a grocery store, a supermarket and a vegetable garden during the month of May 2011. The parasites and / or commensals found in lettuce were Entamoeba coli (67%), Entamoeba histolytica (20%), Giardia sp (13%) and Ascaris lumbricoides (7%). The analysis showed the presence of parasites and / or commensals in all samples, except in the cultivated garden which showed poor sanitary conditions, probably due to contamination in the shipping and handling by third parties in supermarket and grocery store. The parasite monitoring sanitary conditions of vegetables sold in urban environments becomes relevant for preventive measures to avoid the continued parasitic cycle and possible future health complications.

Prevalência das enteroparasitoses em escolares após Programa de Saneamento Ambiental (Bahia Azul) realizado em Salvador, BA

Introduction: The intestinal parasites continue to represent a significant public health problem, due to the large number of infected people and the various organic changes that can cause. The intestinal parasites become more prevalent in villages with high population density absence or inadequacy of sanitation and adequate, and personal hygiene practices and inadequate housing. Objective: To determine the prevalence of intestinal parasites Ascaris lumbricoides, Trichuris trichiura and Giardia duodenalis in children of school age (7-14 years) living in the city of Salvador, Bahia, which were part of the Environmental Sanitation Program (Bahia Azul) covering eight different sewage basins in the years 1997/1998 and 2003/2004. Methods: Data were collected pre-coded questionnaire administered to the parents of students, collecting information socioeconomic, environmental and housing conditions. Stool samples were analyzed for each school in the Laboratory of Parasitology of the ISC, UFBA. The database was built and analyzed by Epi Info program (version 3.5.1/2008) were built where overall prevalence rate and Basin depletion of parasites. We compared the overall prevalence rates (at least one parasite) before and after the intervention health, as well as species of parasite. Results: The overall prevalence before the intervention was 56,2% (N = 729) and 42,5% after the intervention (N = 890), down -24,5%. The prevalence observed for each species A. lumbricoides, T. trichiura and G. duodenalis before intervention was respectively 31,4%, 35,8% and 9,9% respectively after the intervention and 24,4%, 28,8% and 6,0%. In relation to variations in prevalence were found to decrease A. lumbricoides, T. Trichiura and G. duodenalis respectively -22,4%, -19,7% and -39,7%. When the results were compared by Basin exhaustion, it was observed that the greatest variation with reduction occurred among students Basin M. Camurujipe to at least one parasite (-51,4%), ...

Parasitos e comensais intestinais em pacientes neoplásicos submetidos à quimioterapia

The objective of this study was to verify the prevalence of intestinal parasites and/or commensals in the neoplastic patients undergoing chemotherapy. Stool samples were analyzed by the method of Lutz (1919) and Rugai (1954), in triplicate. This work was composed of three groups, the first one (GI) formed by neoplastic patients that are not undergoing chemotherapy, the second (GII) comprised patients who were undergoing chemotherapy, and the third group (GIII) consisting of patients who completed chemotherapy. A total of 30 patients (GI-5, GII-18 and GIII-7) were screened at the Assis Regional Hospital of the Unified Health System of Assis, São Paulo.Additional information on antiparasitic treatment and tumor type were obtained by questionnaire. The positivity was 66.7% (20 cases) for intestinal parasites and/or commensals. The helminths were Ascaris lumbricoides (36.7%), Hookworms (20%) and Hymenolepis diminuta (3.3%). Among the highlights are protozoan Giardia lamblia (46.7%), Entamoeba coli (6.7%), E. histolytica /dispar (3.3%), Endolimax nana (3.3%) and Iodameba butschlii (3.3%). The high frequency of intestinal parasites and/or commensals in the neoplastic patients can be attributed to poor personal hygiene and lack of immunity to reinfection and poor knowledge of the prophylaxis of infection by protozoa and helminths. The results indicate the necessity of adopting a new criterion for neoplastic patients undergoing chemotherapy, primarily performing parasitological diagnosis, treatment and monitoring of cure of intestinal parasitic infections in this risk group.

Diagnóstico parasitológico de horticultures no monitoramento da contaminação parasitária em ambientes rurais

The objective of this study was to detect possible carriers of parasites and/or commensals between the horticulturists of Fair of the Producer from Upper Paranaiba, Minas Gerais. A total of 30 horticulturists were instructed to collect three stool samples on alternate days during the months of August and September 2007. Horticulturists were positive 40% for one or more parasite and / or dinner, and found: Giardia lamblia (3.5%), Entamoeba histolytica / E. dispar (7%), Entamoeba coli (13%), Endolimax nana (13%) and Ascaris lumbricoides (3.5%). Stool of gardeners is of importance in monitoring parasite sanitary conditions of vegetables sold in urban environments.

Anthelmintic efficacy of ivermectin and abamectin, administered orally for seven consecutive days (100 mu g/kg/day), against nematodes in naturally infected pigs

The present study aimed to evaluate ivermectin and abamectin, both administered orally in naturally infected domestic swine, as well as analysing if the EPG (eggs per gram of faeces) values were equivalent with the ivermectin and abamectin efficacy obtained by 'parasitological necropsies. The animals were randomly selected based on the average of three consecutive EPG counts of Strongylida, Ascaris suum and Trichuris for experiment I, and of Strongylida and Trichuris for experiment II. After the random draw, eight animals were treated, orally, during seven consecutive days with 100 mu g/kg/day ivermectin (Ivermectina (R) premix, Ouro Fino Agronegocios), eight other animals were treated, orally, during seven consecutive days with 100 mu g/kg/clay abamectin (Virbamax (R) premix - Virbac do Brasil Industria e Comercio Ltda.), and eight pigs were kept as controls. EPG counts were performed for each individual animal at 14th day post-treatment (DPT). All animals (control and treatment) were necropsied at the 14th DPT. The results from both experiments demonstrate that both ivermectin and abamectin, administered orally for a continuous period of seven days, at a daily dosage of 100 mu g/kg, were highly effective (>95%) against Hyostrongylus rubidus, Strongyloides ransomi, Ascaris suum and Metastrongylus salmi. Against Oesophagostomum dentatum, abamectin presented over 95% efficacy against both evaluated strains, while ivermectin reached other strain as resistant. Regarding T. suis, both ivermectin and abamectin were effective (efficacies >90%) against one of the tested strains, while the other one was classified as resistant. Furthermore, the EPG values were equivalent with the ivermectin and abamectin efficacy obtained by parasitological necropsies. (C) 2014 Elsevier Ltd. All rights reserved.
