Perfil da transmissão e prevalência da cisticercose bovina em propriedades rurais do Triângulo Mineiro / Transmission and prevalence profile of bovine cysticercosis in rural properties of Triangulo Mineiro, Brazil

A cisticercose pode acometer o bovino, que desenvolve a larva da Taenia saginata. Apesar da importância da cisticercose para a saúde pública, para a saúde animal e para economia, a realidade epidemiológica da ocorrência dessa zoonose no Brasil é pouco conhecida. No estado de Minas Gerais a maioria dos dados é obtida dos serviços oficiais de Inspeção Sanitária nos matadouros-frigoríficos, sendo poucas as informações baseadas em dados de campo oriundos de animais vivos. Com o objetivo de avaliar a situação epidemiológica da cisticercose bovina em pequenas e médias propriedades rurais de quatro municípios, situados na região do Triângulo Mineiro, se pesquisou a ocorrência e os principais fatores de risco associados à transmissão da doença nessas propriedades. Dessa forma, foi realizado um estudo epidemiológico de corte transversal envolvendo as 68 propriedades localizadas nas zonas rurais dos quatro municípios, onde foram coletadas 1002 amostras de sangue bovino e aplicado um questionário epidemiológico. O diagnóstico sorológico da cisticercose foi realizado por triagem pelo teste ELISA indireto e os casos suspeitos foram submetidos ao Imunoblot para confirmação. Este estudo revelou a prevalência de 4,7% de cisticercose bovina nas propriedades da zona rural dos municípios amostrados, no período de julho a agosto de 2013. Os fatores que se mostraram estatisticamente significantes para a transmissão da cisticercose foram a expertiness do responsável pela propriedade (RC 5,81 IC 1,87-8,66), a renda familiar (RC 6,02 IC 1,33-8,77) e a qualidade da água da propriedade (RC 9,40 IC 1,97-9,59). Outros fatores foram observados com menor significância. Esses resultados identificaram os principais fatores que interferem na transmissão da cisticercose bovina, permitindo subsidiar medidas de prevenção e controle dessa importante zoonose na região do Triângulo Mineiro.(AU)

Cysticercosis can affect cattle which develop the larvae Taenia saginata. Despite the importance of cysticercosis for public animal health and for the economy, the epidemiological reality of such zoonosis in Brazil is little known. In the southeastern region of the State of Minas Gerais most of the data are obtained from the official Sanitary InspectionServices in slaughterhouses, but little information based on field data from live animals. In order to assess the epidemiological situation of bovine cysticercosis in small and medium-sized rural properties of four municipalities, located in the region of Triângulo Mineiro, we searched the occurrence and the major risk factors associated with transmission of the disease in those properties. We conducted a cross-sectional epidemiological study involving 68 properties located in rural areas of the four municipalities, where there were collected 1002 bovine blood samples and applied an epidemiological questionnaire. The serological diagnosis of cysticercosis was conducted by sorting through indirect ELISA test, and the suspected cases were subjected to Immunoblot for confirmation. This study revealed the prevalence of 4.7% of bovine cysticercosis in rural properties of the municipalities sampled from July to August 2013. The factors which were statistically significant for the transmission of cysticercosis were the expertise of those responsible for the property (OR 5.81 IC 1,87-8.66), the family income (OR 6.02 IC 1.33-8.77) and the water quality of the property (OR 9.40 IC 1.97-9.59). Other factors observed were of lower significance. These results identified the main factors which interfere in the transmission of bovine cysticercosis, allowing to subsidize preventive measures and to control this important zoonotic disease in the region of Triângulo Mineiro.(AU)

Cysticercosis report of three cases form Qatar

This article reports three cases of cysticercosis seen in the State of Qatar between 1983 to 1996. The lesion in case 1 was present in the left side of the neck in a 24-year-old Indian woman, simulating branchial cleft cyst; In case 2 the cyst had involved soft tissue and muscle of the chest wall in a 17-year- old Qatari girl, presenting as left breast mass, presumed to be a fibradenoma; Case 3 was a 24-year- old Bangladeshi man who presented with discharge from the left eye which on ophthalmologic examination was found to be from a conjunctival cyst. He had a history of headache and double vision. A brief account of the geography, life cycle, clinical features, pathology, diagnosis and treatment of cysticercosis is presented

Estudio cualitativo y cuantitativo de la presencia de posoncósferas de taenia solium en el tejido muscular de cerdos con y sin cisticercosis / Qualitative and quantitative study on taenia solium posoncospheres in pigs with and without cysticercosis in muscular tissues

It was determined the presence of posoncospheres in muscular tissues in 20 natural cysticercotic pigs and in 20 pigs apparently free of taenia solium metacestodes. Ten differents anatomical regions were dissected, giving 400 samples in total. The animals were slaugthered in Ecatepec, México State, México. The samples were kept in bottles with saline and were processed in the Laboratorio de Biología de Parásitos, Facultad de Medicina, Universidad Nacional Autónoma de México (UNAM); cysticercus were counted and later on the resulting muscular mass was grinded and observations were made in the sediment for posoncospheres search. Mann-Withney statistical method revealed meaningful differences between postoncospheres in cysticercotic pigs and not apparently cysticercotic pigs. The linear correlation analysis showed no relation between cysticercus quantity and postoncospheres quantity in the same samples. Postoncospheres were found in cysticercotic animals and in those apparently free of cysticercus, in the last group the quantity was bigger

Aspectos epidemiológicos da teníase-cisticercose na área endêmica de Lagamar, MG / Epidemiological aspects of cysticercosis due to Taenia solium in the endemic area of Lagamar, MG

An epidemiological inquiry of humancysticercosis due to Taenia solium was carried out in Lagamar, Minas Gerais State, Brazil, in 1992. A survey of 1109 houses with 3344 inhabitants was made. The inquiry included 875 (86 per cent) families and the questionnaire was answered by an informer, who was the father in 80 per cent of the cases. One hundred pigsties, sheltering 406 swines in extremely precarious conditions, were found in 100 (11.4 per cent) houses. A history on taeniasis in some member of the family was verified in 300 (34.2 per cent) houses. A history of seizures was referred to by 125 (14.2 per cent) of families. The outset of convulsion in adult age was characterized in 39 (37.8 per cent) families. A history of mental disorder was reported in 53 (6.0 per cent) of houses. Stool examinations were positive for Taenia spp in 24 (1.3 per cent) of samples examined per cent.

Relacion teniasis cisticercosis en trabajadores del materno municipal de Cochabamba / Teniasis-cisticercosis Relation in workers of the Cochabamba council drugery

La importancia del consumo de carne de cerdo infectada con cisticerco cellulosae causante de la teniasis, radica sobretodo en adquirir una posterior cisticercosis de localizacion cerebral. El grupo estudiado, constituido por la totalidad de los trabajadores del Matadero Municipal, es considerado de alto riesgo por la manipulacion de carnes contaminadas y el supuesto gran consumo de las mismas de las mismas por su costo reducido. En el estudio, se recabaron datos en ralacion a habitos higienicos, alimenticios y vivienda simultaneamente se realizaron examenes coproparasitologicos duplicados. El estudio inmunologico para cisticercosis, correlacionado a tecnicas de inmunofluorecencia indirecta (IFI) y ensayo de la enzima ligada al inmuno absorbente (ELISA) fue realizado en el Instituto Boliviano de Biologia de la Altura (IBBA) de La Paz. Los resultados mas descollantes fueron que de la totalidad de los trabajadores el 8,5% presentaron teniasis, entretanto que el analisis inmunologico dio un 36,5% de posivilidad mas un 11,5% de casos dudosos, sobre el total de la poblacion estudiada
