SUMMARY Trichomonas vaginalis infections have been associated with other diseases so that epidemiological studies of the parasite are important and help to prevent the spread of the disease. This study aimed to determine the prevalence of T. vaginalis in female patients of 19 counties in southwestern Rio Grande do Sul, Brazil. For diagnosis, was used direct examination, followed by applying a socio-epidemiological questionnaire. We analyzed 300 women and 9% were infected by Trichomonas vaginalis. The highest frequency occurred in women between 18 and 39 years old, single/divorced/widowed, whose family income was at one minimum wage or less, and they had not completed the primary school. Statistically significant risk factors were: women reporting two or more sexual partners in the last year were 3.3 times more likely to acquire the parasite, and those in use of oral contraceptives were 2.7 times more likely to have T. vaginalis. Importantly, 33% of the asymptomatic women were infected, and most of the negative results were from women presenting symptoms consistent with the infection. The findings emphasize that it is necessary to expand the knowledge of individuals about the disease, especially among women with the above mentioned risk factors and also to include the regular screening of Trichomonas vaginalis infections in health centers.
<p class="Default" style="text-align: justify;">Introdução: As hortaliças, especialmente as ingeridas cruas, têm importância para a saúde pública, pois são amplamente consumidas pela população, e podem conter diferentes formas evolutivas de parasitos, servindo como importante via de transmissão de enteroparasitoses. Objetivos : Analisar a presença de formas transmissíveis de enteroparasitos em hortaliças consumidas cruas na cidade de Pelotas, RS, Brasil, no período de abril a setembro de 2011. Metodologia: Foram estudadas amostras de alface (Lactuca sativa), agrião (Nasturtium officinale) e rúcula (Chicarium sp), num total de 100 unidades, provenientes do comércio (supermercados e feiras livres). As hortaliças in natura foram lavadas com água destilada e submetidas à sedimentação por quatro horas. Ao final, os sedimentos foram analisados pelas técnicas de HPJ, Faust e Dicromato de sódio e 29% das amostras evidenciaram a presença de alguma forma parasitária. Resultados: A hortaliça que apresentou maior prevalência de parasitos foi a rúcula (42%), seguida do agrião (25%) e da alface (24%). As principais espécies de importância médica e veterinária encontradas foram cistos de Entamoeba coli, Endolimax nana, Giardia lamblia, ovos de Ascaris spp., Toxocara spp. e larvas de ancilostomídeos. As feiras livres apresentaram maior frequência de amostras positivas, e o método de HPJ foi o que obteve maior acurácia diagnóstica.</p><p class="Default" style="text-align: justify;">Conclusão: Ressalta-se a importância das hortaliças na transmissão de enfermidades parasitárias, havendo consequentemente necessidade de medidas que propiciem uma melhoria na qualidade higiênico-sanitária destas.</p>
Parasites are often a public health hazard, especially among schoolchildren. The transmission of these parasites is associated with poor hygiene and sanitation, as well as close contact between people. This study aimed to evaluate the occurrence of intestinal parasitic infections in schoolchildren from the rural and urban areas of the Palmeira das Missões county, a major town in northwestern Rio Grande do Sul State. Fecal samples from 209 schoolchildren aged three to fourteen were analyzed. The Hoffman, Pons and Janer, Faust, Ritchie, and Kinyoun's stain for coccidea parasite detection techniques were applied. 59.3% of the patients were positive for pathogenic or commensal parasites. The most common parasites were Ascaris lumbricoides, Entamoeba coli, Giardia duodenalis and Cryptosporidium spp., respectively. There were no significant differences in positivity among schoolchildren from rural and urban areas. Low family income and the mothers' schooling (up to 8 years of education) were statistically significant for the presence of parasites. This is the first parasite study carried out in the Palmeira das Missões county.
