In this study two further axenic Giardia isolates obtained from a silvery marmoset Callithrix argentata (Callithricidae) and a red-bellied guenon Cercopithecus erythrogaster (Cercopithecidae) are described. Biological features of the new primate Giardia isolates, such as morphometry of trophozoites, generation time and procedure of axenic isolation are presented.
