Abstract
The pathogenicity of Eimeria mulardi has been studied in mule-duckling s orally inoculated with sporulated oocysts. With two dose levels (10( 5) or 10(6) oocysts per bird), a significant loss of body weight was o bserved, whereas no loss of weight was observed with a dose level of 1 0(4). With a dose of 10(6) oocysts per bird, inflammatory and haemorrh agic changes associated with obstruction mainly involving the end of t he jejunum, the ileum and the caeca were seen from day 5 post-inoculat ion. Pathogenicity of Eimeria mulardi is due to the last generation of meronts and essentially to gamonts.
