“…Similar to earlier reports in various endemic areas, we identified the masseter muscles, tongue, heart muscles, triceps muscles, and thigh muscles as the preferred areas (predilection sites) for the cysts causing bovine cysticercosis (17)(18)(19). A number of factors such as muscle activity, animal's age, and geographical area seem to determine the predilection sites in slaughtered cattle (18,20). According to previous studies on cattle, the prevalence rate was 0.142% in France (8), 1.6 % in Zimbabwe (21), 2.3% in India (22), 0.75% in Madagascar (23), 0.14% in Egypt (24), and 1.2% in Mexico (25).…”

Objective: Bovine cysticercosis is a cattle infection caused by a tapeworm, Taenia saginata. While the condition is relatively innocuous, the parasite infects the small intestine of humans in its mature stage and causes a few specific symptoms such as abdominal pain and nausea. Methods: Between February 2013 and February 2014, a total of 640 cattle were randomly selected from all the cattle sent to the abattoir, and some internal organs and skeletal muscles of these cattle were inspected. Results: Overall, 11 (1.71%) cattle were infected with the larval form of the cestode parasite T. saginata. In addition, the infection was more prevalent in cattle aged above 12 months than in those aged below 12 months [10 (2.06%) vs. 1 (0.64%)]. The prevalence of infection was significantly higher in female animals [8 (3.72%)] than in male animals [3 (0.70%)] (p<0.05). However, no significant difference was found between the rates in the 2 age groups or in different seasons. While the infections were detected in several visceral organs, no significant difference was found between their infection rates. Conclusion: The comparatively high prevalence of Cysticercus bovis infection in the cattle in Tabriz, Iran, may contribute to economic and health problems in the country's meat industry. On the other hand, the role of public health education in C. bovis infection control cannot be neglected.

“…Em vários estudos foi mostrado que, através do fatiamento completo dos sítios de predileção, a média de prevalência aumenta de cinco a cinquenta vezes mais que a inspeção de rotina (Geerts et al, 1980;Minozzo et al, 2002;2004). Porém, esta metodologia leva a depreciação comercial dos cortes.…”

RESEARCH OF Cysticercus bovis ANTIBODIES BY ELISA TEST IN SLAUGHTERHOUSE ANIMALS ABSTRACT:In order to standardize a serological test for diagnosing cysticercosis in cattle, 812 animals have been tested, most of them halfblooded zebu cattle, males and females, from age groups ranging from 18 months to 60 months. The animals had come from 139 municipalities in the State of Parana. The animals were identified and slaughtered in a slaughterhouse in the metropolitan region of Curitiba/PR-Brazil. From the animals that presented cysts during the post-mortem inspection, blood samples were also collected and submitted to the ELISA test for antibodies againstC. bovis. The sensitivity coefficient in the ELISA test was 83.6%, and the specificity coefficient was 92.8%. Therefore, the ELISA test proved to be more sensitive than the post-mortem examination, because the latter failed to detect 06 carcasses with mild infection with cysticercosis (PPV 99.7% -ELISA).

“…Na África as perdas por cisticercose bovina estão estimadas em US$ 1.000 e 2.000(milhões), onde a impossibilidade prática de manter o gado livre da infecção continua frustrando o crescimento de uma indústria de carne rentável em muitos países em desenvolvimento. Estes índices podem ser ainda maiores uma vez que as prevalências da cisticercose são calculadas tendo como base o método de corte e olha que apresenta baixa sensibilidade (MINOZZO et al, 2002).…”

ResumoA cisticercose é a patologia mais encontrada na Inspeção post mortem em bovinos abatidos em estabelecimentos com Serviço de Inspeção Federal (SIF). No Brasil a média da prevalência desta parasitose é de 5%, porém, estes índices podem variar segundo a região anatômica avaliada, região geográfica ou período de realização de trabalho. Para conhecer a prevalência desta patologia em bovinos, no Estado do Paraná, foi realizada uma pesquisa durante seis meses, entre julho a dezembro de 2000, em animais procedentes de 137 municípios, que foram abatidos no Frigorífico Argus, Região Metropolitana de Curitiba. A prevalência de animais positivos encontrados com Cysticercus bovis variou de 0 a 27,27% com média de 3,83% entre os 26.465 bovinos inspecionados. Os municípios com maior número de animais abatidos tiveram prevalência aparente no lote entre 2,8 a 5%. De acordo com o sexo dos animais não foi verificada predileção ou especificidade parasitária sendo que nos machos foi encontrado o índice de 3,81% e nas fêmeas 3,93 %. Todos os cisticercos encontrados vivos passaram pelo processo de desinvaginação, coloração por carmim acético e identificação microscópica constatando que 100% eram C. bovis. As implicações epidemiológicas destes achados são discutidas no presente trabalho. Palavras-chave: Cysticercus bovis, cisticercose bovina, zoonoses, prevalência, epidemiologia AbstractCystercosis is the most frequently detected pathology in post mortem inspection in bovine slaughtered at establishments under the Federal Inspection Service (SIF). In Brazil, the average prevalence of this parasitosis is 5%, but the rates can vary according to the anatomic area screened, the geographic region, or the period of time the work was carried out. In order to find out the prevalence of this pathology among bovine, in the State of Parana-Brazil, a six months research was carried out -from July to December, 2000 -in animals originating from 137 towns and slaughtered in the Argus Cold Store, located in the Metropolitan Area of Curitiba. The prevalence of positive animals found with Cysticercus bovis varied from 0 to 27.27% with an average of 3.83% among the 26 465animals inspected. The towns with larger numbers of slaughtered animals had an apparent prevalence in allotment between 2.8% to 5%. Regarding sex, a 3.81% rate was found among males and 3.93% among females, but no parasitary specificity or preference were detected. All cystercercus found alive were submitted to the desinvagination process, staining with acetic carmin, and microscopic identification evidencing that 100% were C. bovis. The epidemiological implications of these findings are discussed in the present work.
