PCR of Utermohl's solution-preserved P. piscicida cells and field-collected samples. (A) PCR of fresh and Utermohl's solution-preserved P. piscicida cells. (B) PCR of preserved field samples collected from Avery Point in November 2000 and June 2001. I, P. piscicida-specific mitochondrial cytochrome b primer set (primers PPCOB3F and PPCOB3R); II, P. piscicida-specific 18S rRNA primer set (primers PP18SF1 and PP18SR1); III, eukaryote universal 18S rRNA primer set (primers 18SCOMF and 18SCOMR).
