Known Acanthamoeba genotypes and their associations with human diseases, i.e., keratitis and granulomatous encephalitis.

Acanthamoeba genotypes	Human disease association
T1	Encephalitis
^T2a	Keratitis, Encephalitis
^T2b - ccap1501/3c-alike sequences	NA
T3	Keratitis
T4*	Keratitis, Encephalitis
T5	Keratitis, Encephalitis
T6	Keratitis
T7	NA
T8	NA
T9	NA
T10	Keratitis, Encephalitis
T11	Keratitis
T12	Encephalitis
T13	NA
T14	NA
T15	Keratitis
T16	NA
T17	NA

*this genotype has been most associated with both diseases

^basis of T2 division into T2a and T2b has been proposed by Maghsood et al., (2005)

NA - no disease association has been found yet
