prevalence of 39% (76/195) of C. tenuicollis in goats and 17.4% (34/195) in
sheep. The percentage of infection in goats was statistically greater to sheep (p
<0.05). However, the extensive management to sheep was the only statistically
significant variable considered to be a risk factor for infection of C. tenuicollis (p
<0.05). In the second chapter was evaluated the physical and sanitary conditions
