          Abstract

          Com o objetivo de diagnosticar a situação do complexo teníase-cisticercose bovina em Minas Gerais, Brasil, foi selecionado o município de São João Evangelista, onde foram coletadas amostras de sangue de 339 bovinos em 15 propriedades rurais, sorteadas aleatoriamente. Em cada propriedade, foi aplicado um questionário socioeconômico para a análise de fatores que favorecem a manutenção do complexo teníase-cisticercose bovina. Foi realizado também o diagnóstico de teníase humana por meio de exame coproparasitológico dos habitantes das propriedades. Encontrou-se a prevalência de 4,1% para cisticercose bovina e a frequência de 2,94% para teníase humana. Entre os fatores de risco para a manutenção do complexo teníase-cisticercose analisados, foi observada uma relação estatisticamente significativa (P=0,042) entre a ocorrência de cisticercose bovina e a ingestão de carne malpassada pelos entrevistados. Concluiu-se que a cisticercose bovina está presente no município de São João Evangelista, MG, em índices considerados endêmicos, sendo o consumo de carne malpassada e não inspecionada o principal fator de risco para a manutenção do complexo teníase-cisticercose, o que reforça a necessidade da adoção de medidas de controle com contínua vigilância epidemiológica e sanitária.

          In order to diagnose the situation of bovine taeniasis-cysticercosis complex in the state of Minas Gerais, Brazil, the city of São João Evangelista was selected, and blood samples were collected from 339 cattle in 15 randomly selected farms. A socioeconomic questionnaire was filled in each property for the analysis of the factors that favor the maintenance of the taeniasis-cysticercosis complex. Additionally, there was the diagnosis of human taeniasis verified by stool examinations of the properties' inhabitants. A prevalence of 4.1% for bovine cysticercosis and the frequency of 2.94% for human taeniasis were found. Among the risk factors, a statistically significant relation (p = 0.042) was found between the occurrence of bovine cysticercosis and the ingestion of undercooked meat. It was concluded that bovine cysticercosis is broadly distributed in the city of São João Evangelista, with rates considered endemic, being the consumption of raw and not-inspected meat the main risk factors for the maintenance of complex taeniasis-cysticercosis, reinforcing the need to adopt control measures with continuous epidemiological and health surveillance.

            Descriptive and spatial epidemiology of bovine cysticercosis in North-Eastern Spain (Catalonia).

            From March 2005 to December 2007, 284 animals from 67 cattle farms (24 dairy and 43 beef) affected by bovine cysticercosis were detected in the region of Catalonia (North-Eastern Spain). Dairy farms were almost twice more likely to be affected than beef farms (OR=1.79, 95% CI=1.08-2.96, p<0.05), and infected premises have a statistically significant (p<0.05) larger number of animals when compared to uninfected farms in Catalonia. The geographical distribution of the infected farms was evaluated and two statistically significant clusters were identified. The most likely cluster was located in the western part of the study region, with 8 out of 10 farms infected. Epidemiological investigations revealed that the 8 farms belonged to the same company. The secondary cluster was located in Eastern Catalonia with 12 infected farms out of 167 cattle farms. No epidemiological links were found among the 12 infected premises. A questionnaire, based on the EFSA risk assessment, was used to assess the most likely route of introduction into each affected farm. Water supply for animals was the route with the highest score in 41.8% of the cases.

              High prevalence of Taenia saginata taeniasis and status of Taenia solium cysticercosis in Bali, Indonesia, 2002-2004.

              An epidemiological survey of taeniasis/cysticercosis was carried out in one semi-urban and two urban villages in three districts of Bali, Indonesia in 2002 and 2004. In total, 398 local people from 247 families were diagnosed by anamnesis and clinical examinations, and 60 residents were suspected to be taeniasis carriers. Among 60 suspected carriers, 56 persons expelled a total of 61 taeniid adult worms after praziquantel treatment. From 398 residents, 252 stool samples were available for analysis of taeniid eggs, coproantigens or copro-DNA for identification of taeniid species, and 311 serum samples were available for detection of antibodies against Taenia solium cysticercosis. Taeniasis prevalences were highly variable among three villages (1.1-27.5%), and only one case of cysticercosis due to T. solium infection was detected. All expelled tapeworms were confirmed to be Taenia saginata by mtDNA analysis. There was no Taenia asiatica human case in Bali. Case control analysis of 106 families chosen at random from 179 families in 2004 and another 106 families from non-endemic areas revealed that risk factors of T. saginata taeniasis for families were: level of education (P<0.01); consumption of beef lawar (P<0.01); and the source of lawar (P<0.01).
