Interakce sauroleishmanií s flebotomy

Tichá, Lucie

Sauroleishmania is a group of less studied parasites that belong to the genus Leishmania (Kinetoplastida: Trypanosomatidae). They circulate between reptile hosts and sand fly vectors (Diptera: Psychodidae). Due to the non-pathogenic character of its species, little is known about their development in reptiles and sand flies. The main objective of this project was to elucidate some missing aspects of Sauroleishmania life cycle. A major part of this thesis aimed to test the susceptibility of various sand fly species to different Sauroleishmania isolates and describe their development in the sand fly intestinal tract. A minor part was devoted to the study of infection in reptiles. First, we investigated the development of Leishmania (Sauroleishmania) tarentolae in three Phlebotomus species. Sand flies were infected through membrane on promastigote suspension and dissected at various time intervals post infection. Leishmania (S.) tarentolae developed in all three species tested and underwent peripylarian type of the development. Moreover, heavy parasite loads were frequently found in Malpighian tubules, which is a unique localization among Leishmania parasites. To summarize the current knowledge on L. (S.) tarentolae, we have also written a review describing the origin, life cycle and application of...
