Červa (1967a,b) studied white mice of the Czechoslovak H-strain weighing 13-15 grams inoculated intranasally by placing 0.02 mL of the A1 strain of Acanthamoeba over the nares of the ethyl-ether anesthetized mice (Cerva, 1967b).
The beta-Poisson model provided the best fit to the data.

Culbertson et al. (1966) studied the pathogenicity of the HN-3 strain of A. castellanii (Culbertson et al., 1966; Marciano-Cabral & Cabral, 2003) on ether-anesthetized-specific-pathogen-free (SPF) mice. Cultures of amebae were grown in trypticase soy broth and diluted so that 0.03 mL of a concentrated suspension could be instilled intranasally into the mice by placing fluid over the nares (Culbertson et al., 1966; Culbertson, Ensminger, & Overton, 1965a; Culbertson, Ensminger, & Overton, 1965b).
The exponential model provided the best fit to the data.
