Cultures of parasites differ from bacterial cultures in that they require what for quality control?

In parasitology, having controls for organisms and media is essential for quality control when culturing parasites. This is because parasites can have very specific growth requirements and can be more sensitive to variations in culture conditions compared to bacteria. Including controls helps ensure that the media used is supporting the growth of the specific parasites being cultured and confirms that any observed growth is indeed due to the intended organisms. Regular checks, multiple media types, and using two tubes of media might be helpful practices but do not address the fundamental need for controls that validate the culture environment and aid in the identification of the parasites accurately.
