Infusoria
Definition:
(n. pl.) One of the classes of Protozoa, including a large number of species, all of minute size.
Example Sentences:

(5) The rumen content became alkaline, and the infusoria count dropped.
(6) Studied were the values of pH and the content of ammonia gas and volatile fatty acids, the total acidity, and the count of Infusoria in the rumen content.
