entamoeba histolytica: genetic diversity of african strains based on the polymorphism of the serine-rich protein gene. | the polymorphism of the serine-rich entamoeba histolytica protein (srehp) among isolates obtained from different geographic regions was analyzed by a nested pcr followed by restriction analysis. thirteen different profiles were generated from 23 e. histolytica isolates from cameroon, zimbabwe and south africa while 20 others were generated from 38 e. histolytica pcr positive stool samples from south africa. one of the profiles was common to isolates from cameroon, zimbabwe and south africa and c ... | 2008 | 18028911 |
