1Detection of Entamoeba histolytica in experimentally induced amoebic liver abscess:comparison of three staining methods显示文摘Objective:To compare the efficacy of three different tissue stains,namely haematoxylin and eosin(H&E),periodic-acid Schiff(PAS)and immunohistochemical(1HC)stains for detection of Entamoeba histolytica(E.histolytica)trophozoites in abscessed liver tissues of hamster.Methods:Amoebic liver abscess was experimentally induced in a hamster by injecting 1×10~6of axenically cultured virulent E.histolytica trophozoites(HM1-IMSS strain)into the portal vein.After a week post-inoculation,the hamster was sacrificed and the liver tissue sections were stained with H&E,PAS and IHC stains to delect the amoebic trophozoite.Results:The three stains revealed tissue necrosis and amoebic trophozoites,but with varying clarity.H&E and PAS stained the trophozoites pink and magenta,respectively,however it was difficult to differentiate the stained trophozoites from the macrophages because of their similarity in size and morphology.On the other hand,IHC stain revealed distinct brown appearance of the trophozoites in the infected liver tissues.Conclusions:It can be concluded that out of the three stains.IHC is the best for identification of E.histolytica trophozoites in tissue sections.Tan Zi Ning Wong Weng Kin Shaymoli Mustafa Arefuddin Ahmed Rahmah Noordin Tan Gim Cheong Olivos-Garcia Alfonso Lim Boon Huat 2012Asian Pacific Journal of Tropical Biomedicine2012,2,1:1
