چکیده انگلیسی
We demonstrate that a proteophosphoglycan-rich gel secreted by Leishmania infantum inside the midgut of Lutzomyia longipalpis sand flies (promastigote secretory gel) is regurgitated along with an average dose of 500 L. infantum metacyclic promastigotes per infected bite. Using both low (103) and high (105) doses of parasites in the ears of BALB/c mice we show that the infections benefit from the presence of vector saliva and parasite gel in the skin. However, chronic infection of the spleen was only enhanced in high dose co-infections with gel. These results provide the framework for a more natural experimental model of visceral leishmaniasis.
