Leishmaniasis is a vector-borne disease transmitted by the intradermal inoculation of Leishmania (Kinetoplastida: Trypanosomatidae) promastigotes together with saliva during the bite of an infected sand fly. Objective. The salivary glands were compared from two vector species, Lutzomyia ovallesi (Ortiz,1952) and Lutzomyia migonei (França,1920) (Diptera: Psychodidae). Material and methods. Protein profiles by SDS PAGE of salivary glands were compared among species as well as their development at several times post feeding. First, mice were immunized to salivary proteins by exposure to biting by L. ovallesi and of L. migonei. Antibodies in these mice against salivary gland-specific proteins were evaluated by immunoblotting. Results. No apparent change was revealed in the kinetic expression of salivary proteins induced by the different physiological states post feeding. Qualitative and quantitative variations were detected in16-18 polypeptides with molecular weights ranging from 6 to 180 kDa. Species-specific proteins were demonstrated for L. migonei and L. ovallesi. In addition, antibodies against salivary gland specific proteins were found in mice immunized by the saliva of both species. Conclusion. Basic information was obtained concerning the nature of salivary gland proteins of L. migonei and L. ovallesi. This information helps to elucidate the role of salivary proteins and their potential as effective tools in screening risk factors in human and other vertebrate hosts. 2010 artículo científico 0120-4157 https://www.redalyc.org/articulo.oa?id=84316250013 en http://www.redalyc.org/revista.oa?id=843 Biomédica application/pdf Instituto Nacional de Salud Biomédica (Colombia) Num.3 Vol.30
