PRELIMINARY 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...

The collagenase of Entamoeba histolytica

The present work was designed to investigate the capacity of trophozoites of Entamoeba histolytica to adhere to and digest human collagen types I and III in vitro. The time-course of binding of ameba to both human collagen types I and III was similar. However, the kinetics of detachment were different for each collagen type. Trophozoites of E. histolytica cultured on heat-reconstituted type I c...

Radiosensitivity of Entamoeba histolytica cysts.

A dose of approximately 8,400 RAD noticeably lowered the number of viable cysts of E. histolytica in a clear, saline suspension, as calculated by the Most Probable Number method. Doses of approximately 16,700 RAD and more destroyed more than 99% of viable cysts. The relation between increasing cyst mortality and increasing gamma-ray dosage is represented by a logarithmic straight line. A differ...
