Indices of Cysticercus tenuicollis (Taenia hydatigena cysts) in abdominal cavity of sheep slaughtered in municipal slaughterhouses. J.Selva Andina Anim. Sci. [online]. 2017, vol.4, n.2, pp.104-115. ISSN 2311-3766.

The purpose of this research was to determine the prevalence of Cysticercus tenuicollis and to identify the variables that may influence parasitic disease in sheep. The study quantified a total population of 362 animals which were examined during the slaughter process, a total of 133 sheep were positive to the presence of the cysticercus so that a period frequency of 37% was obtained in the population. In the investigation it was determined that there is no dependence of the race, sex and origin of the animals for the presentation of the parasite inside. The distribution of the parasite was identified in the abdominal cavity of sheep slaughtered, determining that the omentum is the anatomical structure most affected by the presence of C. tenuicollis, among the affected organs are: liver, mesentery and peritoneum with an average diameter by cysticercus between 2.5 and 3.7 cm depending on the organ or structure infested. Statistical analysis Chi2 determined that the parasite C. tenuicollis affects each and every one of the animals without differences of races, sex and origin since the probability of occurrence in the three variables proposed is higher than that established and the parasite does not differs with any of the categories described above.
