چکیده
Results comparing the time needed for the development of cytopathic effects in cell cultures with that needed to cause death in mice using inocula of Naegleria and Acanthamoeba are presented. The significance of the source and concentration of the inocula is demonstrated. The use of cell cultures as an indicator of the pathogenicity of free-living amoebae is discussed.

متن کاملThe Salmonella pathogenicity island 2-encoded type III secretion system is essential for the survival of Salmonella enterica serovar Typhimurium in free-living amoebae.
Free-living amoebae represent a potential reservoir and predator of Salmonella enterica. Through the use of type III secretion system (T3SS) mutants and analysis of transcription of selected T3SS genes, we demonstrated that the Salmonella pathogenicity island 2 is highly induced during S. enterica serovar Typhimurium infection of Acanthamoeba polyphaga and is essential for survival within amoebae.

Background: The free-living amoeba called amphizoic amoebae, have the ability to live in natural environmental resources, including water, soil, dust and body tissues of humans and animals. Unlike other free-living amoebae, Neagleria fowleri could cause fatal disease called Primary Amoebic Meningoencephalitis in immunocompetent humans and animals. The disease affects the meninges membrane of br...
