A stand of Paramecium novaurelia was found in Boston Massachusetts, USA, the first on this continent. Molecular studies (RAPD and sequencing ofrRNA [3'SSUrRNA-ITS1, 5' LSU rRNA] and COI mtDNA fragments) of P. novaurelia strains show intra-specific polymorphism within the species as strain clusters characterized by variable relationships.
