“…During the surveys, it was possible to observe in each PSI the average number of students in classrooms was 30 and an insufficient number of employees for cleaning; the hygiene of toilets were not appropriate since soap and toilet paper were not available in the most of PSIs. These characteristics of the infrastructure and health profile of PSIs may be involved in the endemics for infectious and parasitic diseases as observed in other municipalities (Nobre et al 2013).…”

Intestinal parasites present close relationship with sanitary conditions water supply and hygiene habits which pose an important problem of public health with high prevalence among individuals with low socioeconomic status, especially in the younger population. In the present paper the authors performed the diagnostic of intestinal parasites in stool examination of children aged up to six years of age assisted by three public education facilities between September 2011 and July 2012 by using the new method of Mariano & Carvalho. Positivity observed for intestinal parasites reached 77.2 %, with rates ranging from 78.0 %, 72.3 and 84.2 % for the institution A, B and C respectively. Among the positive samples, there was higher frequency of contamination by protozoa (51.2 %), especially for Giardia lamblia (31.2 %). Among the helminthes, the most common were Ascaris lumbricoides (28.8 %) and Trichuris trichiura (17.6 %). The high prevalence of intestinal parasites, both protozoa and helminthes, was significantly associated with eating raw foods without proper hygiene. These results demonstrate the need for improved hygiene habits in parasitism prevention and adequate learning resources to teach preschoolers better habits of hygiene before the consumption of raw foods.

“…However, the prevalence of IPIs was slightly higher in males than that in females. Some studies reported that gender and age were not associated with the risk of parasitic infection and reported the effect of environmental conditions on the transmission of parasites [21,33,34].…”

Introduction: Intestinal parasitic infection (IPIs) is one of the most important health problems in the developing countries. Study on the prevalence of IPIs in various communities is a prerequisite for the development of appropriate control strategies. The aim of this study was to evaluate the prevalence of intestinal parasites among the general population in Mazandaran province, northern Iran. Methodology: This study was conducted on 4,788 specimens collected from 17 urban areas (2,515 samples) and 34 rural areas (2,273 samples) within January-December 2016. Fecal specimens were examined by direct wet mounting, formalin-ether concentration, modified ZiehlNeelsen, and trichrome staining methods. Results: The overall infection rate of intestinal parasite was 14.2% (680/ 4,788). Blastocystis hominis and Giardia lamblia were identified as the most frequent parasites. Protozoa, helminths, and polyparasitism (co-infections with two or more parasite species) were observed in 12.3%, 1.03%, and 0.85% of the specimens, respectively. Furthermore, IPIs showed a significant association with household income, place of residence, washing of vegetables, exposure to soil and season (p < 0.05). Conclusions: Based on the findings, parasitic infections are still a major public health concern in the north of Iran that requires special attention. Therefore, the major key to success in the prevention of IPIs is the execution of some interventions, including patient screening and treatment, public education, and improvement of sanitary conditions.

“…The presence of different parasitic species demonstrates that the population of Diamantina is supposedly exposed to several debilitating diseases, such as hookworm infections, ascariasis, giardiasis and amebiasis. Indeed, a survey recently carried out in the city demonstrated that local children were infected with some of these pathogens 20 . The varied contamination should be related to the fact that these kinds of parasites share many similarities in their life cycle, especially in relation to the elimination route of potentially contaminant structures, i.e.…”

ObjectiveThe present study aimed to evaluate the presence of helminthes and intestinal protozoa in vegetables commercialized in Diamantina, a municipality located at Jequitinhonha Valley, one of the poorest regions of the world. MethodsA total of 108 specimens, including lettuce, green onion and rocket, were monthly collected from the most popular open street market, green grocery and supermarket of the municipality. The samples were processed by a concentration method and evaluated by light microscopy for parasitological identification. ResultsThe percentage of contamination was 50.9% (55/108), with predominance of nematode larvae (36.5%), cysts of Entamoeba coli (26.0%) and eggs of hookworms/Strongyloides spp. (12.9%). Lettuce showed greater contamination rate (61.1%) and samples from the open street market were more contaminated (77.8%). Information collected at each point of sale pointed the field cultivation as the critical step for such contaminations. ConclusionVegetables marketed in Diamantina presents a wide variety of intestinal parasites, which may represent a potential risk to the health of consumers of fresh vegetables.Keywords: Foodborne diseases.

R E S U M O Objetivo O presente estudo teve como objetivo avaliar a presença de helmintos e protozoários intestinais em hortaliças comercializados em Diamantina, um município localizado no Vale do Jequitinhonha, uma das regiões mais pobres do mundo. Métodos Cento e oito exemplares, incluindo alface, cebolinha e rúcula, foram mensalmente coletados em uma feira livre, uma quitanda e um supermercado do município. As amostras foram processadas por um método de concentração e avaliadas por microscopia óptica para pesquisa de estruturas parasitárias. Resultados
