Abstract
S Thaithong N Siripoon N Seugorn D Bunnag GH Beale Electrophoretic variants of enzymes in isolates of Plasmodium falciparum P malariae and P vivax from Thailand Transactions of The Royal Society of Tropical Medicine and Hygiene Volume 83 Issue 5 September 1989 Pages 602–605 https//doiorg/101016/0035920389903684A new electrophoretic variant of glucose phosphate isomerase GPI which we now denote GPI3 has been found in isolates of Plasmodium falciparum from 6 patients all of whom acquired the infection in the same region in or near Prachinburi province of Thailand In other regions from which 453 isolates have been tested only GPI1 and/or GPI2 have been found Two isolates of P malariae from patients at Kanchanaburi showed a band of GPI activity on cellulose acetate gels at a cathodal position quite distinct from that of any previously known GPI variants in other human malaria parasites Thirtynine isolates of P vivax from 3 regions of Thailand have been examined for variants of GPI and lactate dehydrogenase LDH Three forms of GPI were found corresponding approximately in band positions to GPI1 2 and 3 of P falciparum The position of the band of LDH activity in P vivax was the same in all the isolates examined and different from that of LDH1 in P falciparum
