Isolation of Acanthamoeba or finding out the cysts from corneal leasions is necessary to confirm the diagnosis of Acanthamoeba keratitis. However, we cannot always find out the cyst from corneal scrapings of the lesions. In these cases the isolation of Acanthamoeba is very important to confirm the diagnosis.
Non-nutrient agar plates are generally used to isolate Acanthamoeba, but it is difficult to get them easily at many hospitals.
To find out another agar that can be used to isolate Acanthamoeba and got easily, Sabouroud's glucose agar plates were compared with non-nutrient agar plates for the isolation of Acanthamoeba.
Both agar plates seeded with Escherichia coli showed a nice growth of trophozoites first and cysts later. A clinical material, stock solution of contact lens used by a suspected patient of Acanthamoeba keratitis, was put on Sabouroud's glucose agar plate seeded with Escherichia coli. After three days of incubation at 25°C Acanthamoeba was found on the plate.
Sabouroud's glucose agar plate was a very useful agar plate for the isolation of Acanthamoeba.
