December 10 - Parvatrema margaritense

One cercaria established in M. helicinus can thus give rise to as many as 1.5 – 2 thousand invasive metacercariae (clones). This is about 100 times as many as the number of cercariae shed by a single T. minuta a day, providing a significant multiplication of a parasite. Another curious observation is that metacercariae in the extrapallial cavity of M. helicinus don’t cause any of the common parasite-related troubles and might better be call commensals. The broader exciting discussion on these topics as well as on their evolutionary implications can be found in the referred papers.
