The samples numbered from Chimp-1 to Chimp-30 are samples preserved in RNAlater at −80 °C.
The samples numbered Chimp-21–30* are the same samples as Chimp-21–30 but preserved in 10% formalin solution and at 4 °C.
The number of parasite elements was counted for each sample and is shown in the table.
The + sign indicates a very high density of unidentified helminth eggs on the slide (2–3 elements on average per microscope field at 40×).
