Secondary amoebic eye infections in mice due to Acanthamoeba sp.

The aim of the present study was to determine the occurrence of eye infections accompanying the infection of the central nervous system and to demonstrate the possible tissue affinity of different strains of amoebae in subsequent infections. The results obtained demonstrate a clear correlation between the occurrence of eye infection and the degree of virulence of the strains. Amoebae isolated from eyeballs and other organs of dead mice did not exhibit any specificity in relation to the organs in subsequent infections. Irrespective of the place of isolation--be it eye or brain--in the subsequent passages, the amoebae were most often found in the brain and lungs, followed only then by the eye of the infected animals.
