“…Results from field study researches are still scarce in this country (Ferreira et al 2012). In several regions of the country, mainly in small counties, there is no inspection of pork prior to human consumption and much of the pork comes from small farms with limited technology (Iasbik et al 2010).…”

ABSTRACT.-Acevedo-Nieto E.C., Pinto P.S.A., Silva L.F., Guimarães-Peixoto R.P.M., Santos T.O., Ducas C.T.S. & Bevilacqua P.D. 2017. Prevalence and risk factors for porcine cysticercosis in rural communities of eastern Minas Gerais, Brazil. Pesquisa Veterinária Brasileira 37(9):905-910. Setor de Medicina Veterinária Preventiva, Departamento de Veterinária, Universidade Federal de Viçosa, Avenida PH Rolfs s/n. Viçosa, Cysticercosis is caused by Taenia solium, a parasitic zoonosis that affects human and pigs raised free-range in developing countries. The epidemiology of the taeniosis cysticercosis complex in Brazil is poorly understood especially when it comes to field research. The aim of this study was to estimate the prevalence and identify the risk factors associated with porcine cysticercosis in rural communities located in the east of Minas Gerais (MG), Brazil. From 371 farms in the county of Tumiritinga/MG, 101 farms from 14 communities were randomly sampled. Blood samples from pigs were collected, and epidemiological questionnaires were carried out. The serum samples obtained were analyzed through immunodiagnosis techniques, including ELISA and Western Blot, both for the detection of antibodies. The data obtained by different surveys were analyzed using EpiInfo 3.5.1 software to determine seroprevalence and risk factors associated with cysticercosis. The prevalence of farms with porcine cysticercosis was 9.9% (10/101) and antibody-based seropositive was 5.3% (13/247). The results indicate that cysticercosis occurs in high level in the rural area never studied before. These results suggest the presence of tapeworm carriers contributing to the occurrence and maintenance of this zoonotic life cycle in the county. Regarding risk factors, the most significant determinants for porcine cysticercosis in the field were free-range pig management (OR: 17.4, p: 0.0001), the method of disposal of human faeces in the environmental (OR: 7.6; p 0.012), and the size of the farm. Porcine cysticercosis was diagnosed only in areas represented by Agrarian Reform Settlements. From the results, it is possible to recommend as a means of control and prevention the destination of human faeces in appropriate sanitary landfills and the production of pigs in an enclosed area. Additionally, improving education in the communities sampled will indirectly affect the spreading of this disease. The results draw attention to the largest studies of this zoonotic disease in human settlements from rural areas due to the lack of knowledge about the epidemiology of the taeniosis-cysticercosis complex. The results could serve as the basis to support public policies aimed at creating an effective program to control the taeniosis-cysticercosis complex in the studied area. Awareness of TC among medical doctors, veterinarians, meat animal family producers and the public should be developed through appropriate information and education.

“…Data on bovine cysticercosis prevalence using serological methods as diagnostic tests in Brazil are scarce and limited to local surveys. Seropositivities rates at animal level have been referred to range from 0.4% to 4.1% in surveys conducted in the state of Minas Gerais (IASBIK et al, 2010;ACEVEDO et al 2012;SANTOS et al, 2013;FELIPPE et al, 2014;GARRO et al, 2015). It seems that the herd-level prevalence could be even higher in Paraíba, once for this study only cows aged ≥ 24 months were used.…”

The aim of this survey was to identify spatial clustering of bovine cysticercosis-positive herds in the state of Paraíba. The state was divided into three sampling groups: sampling stratum 1 (Sertão mesoregion), sampling stratum 2 (Borborema mesoregion) and sampling stratum 3 (Zona da Mata and Agreste mesoregions), and 2382 cows aging ≥ 24 months from 474 farms were sampled. Serological diagnoses of bovine cysticercosis were initially done by means of indirect ELISA, and positive serum samples were confirmed by a immunoblot test. Herds were deemed positive for cysticercosis if they presented at least one positive animal in herds of up to 29 females, and two positive animals in herds with more than 29 females. The spatial clustering was assessed using the Cuzick-Edwards k-nearest neighbor method and spatial scan statistics. A significant clustering of positive herds was detected in the southern part of the Borborema mesoregion. Given that serological tests for bovine cysticercosis are not widely available, and also that replacement and maintenance of herds through animal purchases is common in the region, it can be concluded that prevention measures should be applied at herd level.

“…Já Moralez et al 2008 Quanto à prevalência de teníase, todas (n=243) amostras de fezes humanas coletadas foram negativas para este parasito. A ausência de casos de teníase observada pode ser devido ao método de coleta das amostras de fezes (única amostra por indivíduo), corroborando com Iasbik et al (2010) e Nieto et al (2012).…”

Esta pesquisa teve como objetivo avaliar as características epidemiológicas do complexo teníase-cisticercose na zona rural do município de Divinésia-MG. Para tanto, realizou-se coleta de 243 amostras de fezes humanas, 435 amostras de soro bovino e 56 de soro suíno. Além disso, foi aplicado questionário para coleta de informações sobre as características socioeconômicas e higiênico-sanitárias da população amostrada. Não foram encontrados animais positivos ao teste ELISA indireto e Immunoblot para cisticercose suína e bovina, nem ovos de Taenia sp. em amostras de fezes humanas. Verificou-se que, apesar da população estudada possuir renda mensal baixa, as famílias residiam em casas bem estruturadas, com banheiro e rede de esgoto, realizavam tratamento antiparasitário de rotina, não consumiam carne malpassada, e vermifugavam os bezerros. Essas características contribuem para o controle do complexo teníase-cisticercose, justificando os resultados obtidos neste estudo.
