Experimental production of new zymodemes of Entamoeba histolytica supports the hypothesis of genetic exchange
Trans R Soc Trop Med Hyg.
1989 Nov-Dec.
Abstract
By mixing in culture zymodemes of Entamoeba histolytica, clones showing a different pattern from the 2 parents have been obtained on 3 occasions. Two new zymodemes (XI alpha- and XXI) have thus been produced, which belong to the third generation of a family of E. histolytica zymodemes apparently obtained by genetic exchange. A hypothesis for the molecular basis of those exchanges is discussed. We report also the observation of probable mutation.
