[Anatomic regions of major occurrence of Cysticercus bovis in bovines under federal inspection at slaughterhouse in the municipality of São José dos Pinhais, State of Paraná from July to December, 2000].
The purpose of this work was to determine the most common anatomic location of bovine cysticercosis, as well as its number per animal. To accomplish these objectives a number of 26,633 bovines from the slaughterhouse Argus Ltd., SIF 1710, located at São José dos Pinhais in the State of Paraná, Brazil, were examined from July to December 2000. The results demonstrated that the head's muscles were infected with a rate of 57.77%, and the cardiac muscles 39.65%, totalizing 97.42% of the infected sites. According to the classification concerning viability, the occurrence of metacestode was 66.97% nonviable (dead) and 33.02% viable (alive). From the Cysticercus alive, 81% of them were located in the head's muscles and 17% in the heart; whereas from those dead, 52.11% were located in the heart's muscles and 47.88% in the hea's one. Of the total of carcasses positives for Cysticercus bovis, 94% of them were infected by only one cyst and 6% by multiple cysts. All the viable cysts were submitted to the morphologic identification being verified that 100% of the parasites were C. bovis.
