Surveys on monieziasis of sheep and goats were Conducted in several runs in the Kanto and the Northeastern regions of Japan.
At first, various technics were examined for the efficiency of detecting cestode ova.
The methods of examination used were as follows: detection of proglottid, filtration and floatation method with saturated saline solution, floatation method, filtration and precipitation method, filtration and precipitation method with formalin and ether, precipitation method, and direct smear method.
The efficiencies of the last-named two methods were found to be too low for practical use.More over, vegetable fibers of fodder contained in the feces were apt to hinder the observation on para-site eggs.
The efficiency of the directdeetection of proglottid was also extremely low.On the contrary, the filtration and floatation method with saturated saline solution was recognized to be the most effective in detecting moniezian eggs in the feces.
Lambs and one-year-old sheep showed high infection rates.
A survey on goat flocks revealed also a similar incidence level.
In several runs, the rate of infection with moniezian cestodes among, sheep was as high as 30 to 80 per cent.
