Diagnosis?
Balantidium coli is the best I can do as about the right size and has flagella and some visible nucleolus. 50:50 confidence level though.
ReplyDeleteWell, from the pictures and videos the movement is compatible with a ciliate. My thinking is that the organism is a Balantidium either coli or suis. Is there anyway to differentiate morphologically between the one of man and that of a pig?
