Lower galactosylation levels of the Lipophosphoglycan from Leishmania (Leishmania) major-like strains affect interaction with Phlebotomus papatasi and Lutzomyia longipalpis
BACKGROUND Leishmania major is an Old World species causing cutaneous leishmaniasis and is transmitted by Phlebotomus papatasi and Phlebotomus duboscqi. In Brazil, two isolates from patients who never left the country were characterised as L. major-like (BH49 and BH121). Using molecular techniques, these isolates were indistinguishable from the L. major reference strain (FV1). OBJECTIVES We eva...
متن کاملDetection of amastigote-like forms in the valve of Phlebotomus papatasi infected with Leishmania major.
A massive and homogeneous amount of amastigote-like forms was detected in the stomodeal valve (SV) and the thoracic mid-gut (TMG) of Leishmania major-infected Phlebotomus papatasi, which received a second blood meal 13 to 21 days post-infection on healthy anaesthetized hamsters. After re-feeding, the infected sand flies were dissected out to examine the morphology of the parasite in SV, TMG and...
متن کاملPhlebotomus papatasi exposure cross-protects mice against Leishmania major co-inoculated with Phlebotomus duboscqi salivary gland homogenate.
Leishmania parasites are inoculated into host skin together with sand fly saliva and multiple exposures to uninfected sand fly bites protect mice against Leishmania infection. However, sand fly vectors differ in composition of the saliva and therefore the protection elicited by their salivary proteins was shown to be species-specific. On the other hand, the optimal vaccine based on sand fly sal...
متن کاملphlebotomus papatasi (diptera: psychodidae) as the vector of leishmania major in kharameh district, southern iran
background: cutaneous leishmaniasis (cl) is endemic in many parts of iran. this study was conducted to investigate the fauna and some biologic factors of sand flies and detect cl vector(s) in kharameh district which is one of the most important foci of the disease in fars province, southern iran. methods: to identify the fauna, a total of 1549 sand flies were collected from april 2014 to marc...
متن کاملA test for genetic exchange in mixed infections of Leishmania major in the sand fly Phlebotomus papatasi.
We tested if genetic exchange was observable between two strains of Leishmania major (Trypanosomatidae) during mixed infection of the sand fly Phlebotomus papatasi. Previous studies suggested that genetic exchange may occur in natural populations of Leishmania at a low frequency, but experimental crosses examining small numbers of progeny (less than 60) did not reveal hybrid parasites. Accordin...
