[Hematological and biochemical changes in lambs experimentally infested with Cysticercus ovis].

The effect was followed up of the experimental infection of Cysticercus ovis on some hematological and biochemical indices in lambs. The experiments were carried out with a total of 14 two-month-old lambs divided into 3 test groups of 4 animals each and a control group of 2 animals. The lambs of the first group were infected with 4000 Taenia ovis eggs, those of the second group--with 7000 T. ovis eggs, and those of the third group--with 30 000 eggs. Both the hematological and the biochemical investigations were carried out prior to the infection and on the 4th, 7th, 12th, 28h, 35th, and 60th day after that. It was found that the infection led to a considerable rise of the leukocyte count. The differential blood picture pointed to a rise of the eosinophil leukocytes and the lymphocytes, and a drop of the neutrophils. The changes observed in all three test groups were better expressed within the period from the 7th up to the 35th day after the infection.
