WebThe ciliate Ichthyophthirius multifiliis is an important pathogen of freshwater teleosts occurring in both temperate and tropical regions throughout the world. The disease, ichthyophthiriosis, accounts for significant economic losses to the aquaculture industry, including the ornamental fish trade, and epizootics in wild fish populations can ... WebThe absence of death ciliates or other pathological changes within 24 hours showed a lack of acute and subacute toxicity of the product. Relative biological value of broiler chicken meat was determined by the intensity of reproduction of ciliate on a nutrient substrate, which contained experimental samples of meat as a source of protein.
