[Experimental meningoencephalitis by Naegleria fowleri in mice]
Experimentally, primary amoebic meningoencephalitis (PAM) is induced by Naegleria fowleri in mouse and development of PAM may be influenced by the strain, weight and sex of mouse, and inoculum size of N. fowleri trophozoite. In this paper, the effect of these factors on PAM development of mouse was studied. N. fowleri trophozoites, strain 0359, were introduced into mouse intranasally under secobarbital anesthesia (0.05 mg/g). PAM was developed more frequently in BALB/c mouse than ICR mouse. The survival time of mouse with PAM was influenced by the weight, that is, it was shorter in 15 g mouse than in the heavier groups. No difference was observed on PAM development according to sex. In case of inoculated amoeba, PAM incidence of 0.5 x 10(4) was markedly decreased.
