a chronic and wasting illness of livestock has been
underestimated and undiagnosed due to various intrinsic factors.
The diagnosis of the disease in small ruminants, especially in
sheep, has not received due attention, inspite of
the striking reports of mortality from many parts of the
country. In the present investigation, the efficacy of four
different methods viz., Direct
Examination, Formal Ether Technique, Alkaline Digestion and Miracidial Hatching
Test were evaluated for the detection of ovine
from 650 sheep belonging to 15 districts of Karnataka were
screened for schistosome egg
out of which 44 (6.76%) samples were positive. Majority of the
cases had Schistosoma indicum
(93.1 %) and very few were positive forS.spindale. Miracidial Hatching
Test was found to be superior in detecting natural ovine schistosomosis,
followed by Alkaline Digestion and Formal Ether Technique.
Direct examination detected none of the cases as positive.
