To detect the rumen ciliates from the outside of their host, the faeces of both sheep and cow and the living or non-living particles adhered to clover were incubated in the culture medium containing hay and wheat flour (Table 2), in which the rumen ciliates thrived. This experiment resulted in finding no viable organisms. The survival time of the ciliates in the rumen fluid dilluted by MC DOUGAHL's artificial saliva under both aerobic and anaerobic conditions was examined. The result is that the ciliates are able to tolerate the mixture of saliva and exposure to air, at least within six hours (Tables 4 and 5). From the above-mentioned results, it seemed that the rumen ciliates are passed from animal to animal by direct transfer through the saliva containing the active organisms and that the resistant cysts or viable rumen ciliate forms are not present either in the food or faeces.
