Percentage identity and divergance matrix of 10 strains of locally isolated Paramecium species from 1 to 10 (FT2.1-FT11.1 respectively) and 24 sequences from GenBank data based on the histone H4 gene fragment. From 11-15 are P. tetraurelia species (XM001425872, XM001455606, XM001452606, XM001452073, XM001459068 respectively). 16 is P. decaurelia (DQ067622), 17 and 18 again representing P.tetraurelia (AJ004699, XM001442554), 19 P.tredecaurelia (DQ067629), 20 P. pentaurelia (DQ067623), 21 is P. primaurelia (DQ067620), 22 P. quadecuarelia (DQ0676630), 23 P. decaurelia (DQ067626). 24 to 29 are P. jenningsi (DQ001056, DQ001064, DQ001062, DQ001059, DQ001061, DQ001057 respectively). 30 P. undecaurelia (DQ067627), 31 P. septaurelia (DQ067624), 32 P. tertraurelia (AJ004700), 33 P. caudatum (AB670962) and 34 P. bursaria (AJ004702).
