چکیده
The effect of 24 anti-amoebic and other chemotherapeutic compounds on six strains of hartmannellid amoebae was studied by tissue culture, agar diffusion, and liquid axenic culture. Of the recognized anti-amoebic compounds only one inhibited growth of the amoebae, which were remarkable for their resistance. Two compounds, hydroxystilbamidine isethionate and 5-fluorocytosine, showed some amoebicidal activity while some others were inhibitory.

متن کاملPotentially Pathogenic Free-Living Amoebae in Contact Lenses of the Asymptomatic Contact Lens Wearers
BACKGROUND Free-living amoebae (FLA) including Acanthamoeba spp. and Hartmannella spp. are the causative agents of serious corneal infection especially within contact lens wearers. Thus contact lenses and their storage case could be a suitable niche for potentially pathogenic amoebae. The main objective of the present study was to evaluate the contamination of contact lenses to free living amoe...
