Isoenzymatic diagnosis of Litomosoides galizai and Litomosoides sigmodontis

Abstract

The morphological diagnosis of the two species, Litomosoides sigmodontis Chandler, 1931 and L. galizai Bain, Petit et Diagne, 1989 is confirmed by the isoenzymatic analysis. In L. galizai, the mannose-phosphate isomerase and the glucose-phosphate isomerase migrate much faster and therefore further than in L. sigmodontis ; a polymorphism at MPI locus is shown in L. sigmodontis that does not exist in L. galizai. The «  L. ? » line, derived from the meriones in which it and L. sigmodontis coexisted, is of the pure sigmodontis type, both in morphology and in isoenzymes.
