Leishmania Life Cycle in the Sandfly
Sandflies (Diptera: Phlebotominae) are vectors of Leishmania parasites, causative agents of important human and animal diseases with diverse manifestations. This review summarizes present knowledge about the vectorial part of Leishmania life cycle and parasite transmission to the vertebrate host. Particularly, it focuses on molecules that determine the establishment of parasite infection in san...
متن کاملEnhanced Leishmania braziliensis Infection Following Pre-Exposure to Sandfly Saliva
BACKGROUND Sand fly saliva has an array of pharmacological and immunomodulatory components, and immunity to saliva protects against Leishmania infection. In the present study, we have studied the immune response against Lutzomyia intermedia saliva, the main vector of Leishmania braziliensis in Brazil, and the effects of saliva pre-exposure on L. braziliensis infection employing an intradermal e...
متن کاملSandfly Fever
Sik,?My thanks are due to Lieutenant Stott and Major Rogers for their criticisms of my paper published in the " Gazette " for August last. Since its publication, Lieutenant-Colonel Birt, K. A.M.C., has very kindly sent me reprints of his recent articles in the Journal of the R. A. M. C. on " Phlebotomus Fever in Malta and Crete" and " Sandfly Fever in India." His clinical description of the fev...
متن کاملSandfly maxadilan exacerbates infection with Leishmania major and vaccinating against it protects against L. major infection.
Bloodfeeding arthropods transmit many of the world's most serious infectious diseases. Leishmania are transmitted to their mammalian hosts when an infected sandfly probes in the skin for a bloodmeal and injects the parasite mixed with its saliva. Arthropod saliva contains molecules that affect blood flow and modulate the immune response of the host. Indeed, sandfly saliva markedly enhances the ...
متن کاملLeishmania major: effect of repeated passages through sandfly vectors or murine hosts.
Virulence for BALB/c mice, infectivity for Phlebotomus papatasi, haemagglutination activity and expression of metacyclic lipophosphoglycan (LPG) were studied in four strains of Leishmania major (LV561, FV1, L119 and Neal) and various lines of the LV561 strain. Attenuated line LV561/AV was passaged five times through sandflies or mice and the resulting lines (AVS5 and AVM5, respectively) and two...
