Mechanism of trifluoromethionine resistance in Entamoeba histolytica.
OBJECTIVES To determine the mechanism of trifluoromethionine resistance in Entamoeba histolytica and evaluate the impact of acquired drug resistance on virulence. METHODS Trifluoromethionine-resistant amoebae were selected in vitro and examined for cross-resistance to antiamoebic drugs, stability of resistance, methionine γ-lyase (MGL) activity, cell adhesion and virulence. Targeted gene sile...
متن کاملTranscriptional and functional analysis of trifluoromethionine resistance in Entamoeba histolytica.
OBJECTIVES Drug resistance in parasitic protozoa is an obstacle to successful chemotherapy. Understanding how pathogens respond to drugs is crucial in preventing resistance. Previously, we have shown that in Entamoeba histolytica, methionine γ-lyase (EhMGL) downregulation results in trifluoromethionine resistance. The transcriptional response, however, of this parasite to the drug is not known....
متن کاملThe cultivation of entamoeba histolytica in HSr+ s medium
In 1926 for the first time Dobell and laid low synthesized and used Hsre+ s ( horse serum, ringer, egg+ starch rice) as a culture medium for growth of E.histolytica. since then this medium along with tens of other media have been used for growth of E.histolytica and other intestinal microorganisms. This medium has been used worldwide in many diagnostic and research laboratories. In Iran, in ...
متن کاملPRELIMINARY COMPARATIVE STUDY OF ENTAMOEBA HISTOLYTICA AND ENTAMOEBA DISPAR BY PCR TECHNIQUE IN IRAN
It has been suggested that two distinct species exist within what was originally known as Entamoeba histolytica and E. dispar. These are Entamoeba dispar for the nonpathogenic and E. histolytica for the pathogenic fonn. Differentiation of these two organisms is of great clinical importance since they are morphologically indistinguishable and both fonns can infect the human intestinal cavity...
