ABSTRACT
Introduction. Localised cutaneous leishmaniasis (LCL) is endemic in the Peninsula of Yucatan. Leishmania mexicana is transmitted to humans by the infectious bite of the insect vector
Lutzomyia olmeca olmeca and possibly by
Lu. cruciata as well. Even though there are several previous studies on the ecology of both phlebotomid sandflies, potential genetic variations have not been determined for geographically separated sandfly populations
Objective. The main objective of this study was to evaluate the existence of variability of morphological characters among populations, and then to evaluate whether or not populations could be distinguished from each other using discriminant analyses
Materials and Methods. Specimens of
Lu. olmeca olmeca and
Lu. cruciata were collected in distinct locations of the southern states of Tabasco, Campeche, Yucatán y Quintana Roo. Thirty one morphological characteristics were measured using a micrometric for every specimen, using consistent techniques for preservation and slide mounting for all samples. Following univariant analyses, we then selected only the statistically significant morphological characteristics for a multivariant analysis to identify group characteristics.
Results. For
Lu. olmeca olmeca, univariant analysis found that 26 out of 31 characteristics were statistically significant, whereas for
Lu. cruciata, 16 out of 31 characteristics were significant. Subsequent multivariate analyses showed that
Lu. olmeca olmeca from Bechanchén were statistically different (discriminant) from the rest of the populations. In the case of
Lu. cruciata, the populations of Dos Naciones and La Libertad were statistically different (discriminant) from the rest of populations studied.
Conclusions. Geographic variability was found among the morphological characteristics of the studied populations at both individual levels using univariant analysis, and for several characteristics considered simultaneously via multivariant analysis. More studies are required to confirm the levels of heterogeneity and genetic isolation among populations of the two studied sandfly species.
