Studies show environmental contamination as a decisive factor for the perpetuation of the epidemiological triad of infection by parasites, posing a risk to human health. This work identified parasitic contamination in peridomestic soils, enteroparasite infection in humans and domestic animals in the Riacho Dantas and Rio do Onha, rural communities of Santo Antônio de Jesus (Bahia, Brazil). Analyses were performed in 53 homes, with soil samples collected in four points as well as collection of human and domestic animals feces from July to October 2015. Soil samples as well as human and domestic animal feces were analyzed. For the analysis of human fecal samples, four methods were used, including spontaneous sedimentation, Baermann-Moraes, Kato-Katz and Graham. For animal fecal samples three methods were used: spontaneous sedimentation, Willis and Rugai. For soil samples, two methods were used: spontaneous sedimentation and Rugai. Of the 636 samples of soil analyzed, 68.7% were positive for some parasitic form, especially non-ciliated protozoa, ciliate protozoa; adults and larvae of the nematodes and hookworms. Of the 144 samples of human feces, 75% were positive, especially for: Endolimax nana, Entamoeba coli, hookworms, Giardia duodenalis, Entamoeba histolytica/E. dispar and Enterobius vermicularis. Of the 21 animal feces samples, 85.7% were positive, especially for the genera Ancylostoma, Toxocara, Trichuris and Giardia. The studied soil samples presented biological contaminants (for example, Toxocara and Ancylostoma) some of which pathogenic for humans and domestic animals. The lack of information regarding the care of domestic soil and direct contact with contaminated soil enabled the detection of parasites with hosts in this environment.

Introdução: O uso de plantas medicinais é uma prática comum de cuidado primário nas populações em geral. Foi introduzido no Brasil, por influência das culturas indígena, africana e europeia e caracteriza-se por ser oriundo do conhecimento e da tradição popular. Objetivos: Sendo o Recôncavo da Bahia uma região de forte influência africana, o objetivo deste estudo foi investigar o uso das principais plantas medicinais e identificar seu uso pela população de um de seus municípios, valorizando o acervo cultural e o saber popular de seus moradores quanto aos benefícios que essas plantas trazem para a população. Metodologia: Para a obtenção dos dados, foi aplicado um questionário sociodemográfico, contendo questões sobre o uso de plantas para fins medicinais em chás ou xaropes com 154 entrevistados. Resultados: Desse universo de pessoas, 74,71% tinham o costume de usar remédios caseiros e 60,0% eram do gênero feminino. Os vegetais mais citados para fins medicinais foram: Lippia alba (n=71), Cymbopogon citratus (n=31), Pimpinella anisum (n=30), Peumus boldus (n=14), Plantago major e Ocimum basilicum (n=13 cada); sendo utilizados principalmente como calmante, dores em geral e contra gases. Quanto ao local de obtenção dos vegetais, os entrevistados cultivavam a planta (94,6%), pegavam do cultivo de amigos e vizinhos (1,8%), compravam na feira livre (1,8%), compravam em farmácia ou adquiriam de outros lugares (0,9%). Conclusões: Os dados evidenciam a relevância da prática do uso de plantas para manutenção da saúde dos moradores do município pesquisado, sendo parte integrante de seu contexto sociocultural. As diferentes finalidades do uso de plantas para fins medicinais mostram que mais estudos são necessários para avaliar as propriedades dessas plantas e seus efeitos no organismo humano.

Studies linking human health to environmental conditions are essential since parasitic diseases are connected to environmental and sanitary aspects. This study identified the prevalence of enteric parasites in an academic community in the municipality of Santo Antônio de Jesus, Bahia, Brazil. The purpose was to determine the existence, or not, of links between infections and socio-epidemiological variables, such as personal hygiene habits, the presence of sewage systems and the environment. Participants answered a questionnaire and received universal collectors for fecal samples. Spontaneous sedimentation methods and Rugai were used for diagnosis. One hundred twenty-one samples were analyzed, in which a 38.8% parasite prevalence was detected as well as a 61.7% rate of monoparasitism, as well as a predominance of protozoa Endolimax nana (78.7%) and Giardia duodenalis (21.3%). Among parasitized individuals, 97.9% lived in the Recôncavo Baiano region. The following statistical significance stands out in the findings, with p<0.05: individuals who had already bathed in the local river were more likely to be parasitized than those who had not (p = 0.034) and individuals who washed their hands more frequently before meals proved to be less prone to intestinal parasitic infections (p = 0.018). Results evidenced the presence of enteric parasites in a number of participants in spite of their being university students. The socio-epidemiological variables analyzed brought to light characteristics that favor the establishment of the epidemiological infection triad, such as improper packaging of household waste on disposal and no records of regular domestic water tank cleaning.  KEY WORDS: Enteric parasites; environment; diagnosis; health education.

Demographic and social studies, as well as economic and cultural factors in a community are important regarding public health. This study identified demographic, socioeconomic and cultural aspects correlated with intestinal parasites in the population of Santo Antônio de Jesus, Bahia-Brazil, from July to October 2015. 53 semi-structured questionnaires were applied to the rural population of the municipality with previous clarification on the purpose of the study. There were questions related to the individual’s gender, family income and parental level of education. Laboratory parasitological analyzes were performed to investigate enteroparasites and produced the following results: 53.7% (n=58) were female; 62.8% (n=66) with monthly family income lower or equal to the minimum wage and 48% (n=48) of adults with incomplete basic education. The main enteroparasites found in this population were: Iodamoeba butschlii, Entamoeba histolytica/Entamoeba dispar complex, Giardia intestinalis, Entamoeba coli and Endolimax nana in addition to some geohelminths, such as hookworms and Enterobius vermicularis. The profile visualized can be understood as a risk factor for the development of certain parasitic infections that are intrinsically associated to the social and economic aspects of vulnerable populations.KEY WORDS: Teenager; adult; child; parasitic diseases.

Objective: this study aimed to associate enteroparasitic infection with nutritional, allergic, and clinical repercussions and the sociodemographic aspects in an academic community in Santo Antônio de Jesus, Bahia, Brazil. Methods: the cross-sectional research was carried out between February 2018 and March 2020, with 121 participants. Spontaneous sedimentation and Rugai techniques were used for the parasitological diagnosis of fecal samples. Allergies and clinical issues and the sociodemographic aspects were studied via a questionnaire, and the nutritional status was obtained from the assessment of body mass index and arm and abdominal circumferences. Results: there was 38.2% positivity for intestinal parasites; 65.9% for female participants; with the majority of eutrophic, between 18-27 years old; heteronormative, and single. Besides, the Endolimax nana (78.7%) and Giardia duodenalis (21.3%) were the predominant species. Statistical significance was found between obesity rates and the presence of intestinal parasites and those with allergic aspects. Nervousness, headache, and back and abdominal pains were the most common symptoms. Conclusions: this study contributes to obtaining data on epidemiological and public health surveys in the Bahian territory, providing a reference for other researchers. The statistical association of these with nutritional and allergic aspects can support future research on this population.
