Abstract
The purpose of the study was observed the DNA distraction in the peripheral blood lymphocytes of sarcocystosis infected ewes by micronuclei assay. Forty sarcocystosis infected ewes and twenty uninfected as a control group were involved in this study. Lymphocytes from peripheral blood of infected and un infected ewes was used for culture and subsequent cytogenetic studies were performed. The results showed that the MNmean of infected ewes was significantly (p? 0. 05) higher 32.05± 0.95 than the uninfected group11.95±0.622. These findings indicated of an increase in DNA damage in infected ewes measured by MN frequency.
