Several species of Acanthamoeba, including A. culbertsoni, A. polyphaga, A. castellanii, A. astronyxis, A. hatchetti, A. rhysodes, A. divionensis. In order to define the mode by which amoebae recognize ECM components and process this recognition, we analyzed Acanthamoeba culbertsoni attachment. They have been implicated in human infections and disease, including Acanthamoeba culbertsoni, Acanthamoeba polyphaga, Acanthamoeba castellanii.

Variosea paraphyletic Holomastigida Phalansteriida Artodiscida Varipodida. All wells were read at nm with a correction wavelength of nm. Entamoeba histolytica Amoebiasis Amoebic dysentery Amoebic liver abscess Cutaneous amoebiasis Amoebic brain abscess Amebiasis cutis Entamoeba gingivalis. In the present study, a BV-2 cell in vitro model was used to gain insight into the microglial cell- Acanthamoeba interaction.

Collectively, these results suggest a mode through which A. Retrieved 31 May Thus, although a large-scale screening of chemokine and cytokine mRNA species was not performed, these observations acanthaomeba consistent with the conclusions that i A.

Exp Parasitol ;30 1: On the other hand, treatment with 5 mM 1,phenathroline resulted in abrogation of activity associated with the, and kDa bands. Echinococcus multilocularis metacestode metabolites contain a cysteine protease that digests eotaxin, a CC pro-inflammatory chemokine.

The blastogenic responses of splenocytes treated with concanavalin A were declined significantly in the experimental group as compared with the control group, but the blastogenic responses of splenocytes treated with polyinosinic acid were not different from the control group. BV-2 cells were maintained in Neurobasal-A medium for 18 h as a negative control or in Neurobasal-A medium supplemented with 0.


For supernatants of BV-2 cells incubated 8 h with A. Parasite Immunol ;1 4: In summary, it is likely that A. Immunization with culture supernatant in experimental amoebic meningoencephalitis.
