In the presence of aqueous extracts (ranging from 1.0 to 32.0 mg/ml), numbers of the viable Acanthamoeba castellanii trophozoites and cysts were decreased during the experimental process. Both extracts showed a time- and dose-dependent amoebicidal action on the trophozoites and cysts. Among the extracts tested, I. oculus showed the strongest amoebicidal effect on the trophozoites and cysts. In the presence of 32.00 mg/ml extract solution in the media, no viable trophozoites were determined from the time of 24 h. Moreover, in the presence of 16.00 mg/ml I. oculus-christi extract, no viable trophozoites were detected in 72 h of the experiment. Effectiveness of I. oculus-christi extract was found moderate against the cysts. In the presence of 32.00 mg/ml extract, only 25.3% of the total cysts were killed effectively. In the case of P. armenea, 40.3% and 23.0% of the trophozoites and cysts were killed in the presence of 32.00 mg/ml extract at the end of the experimental process (72 h), respectively.en10.1007/s00436-011-2524-zinfo:eu-repo/semantics/closedAccessArticle1102570565217351492-s2.0-84857062615Q1WOS:000299519800011Q2
