“…Our success rate is also higher than that of Pozio et al (1985), Ryan et al (1987) and Knechtli and Jenni (1990) who recorded 2.2-3.2 %, 10.5 % and 2.7 % refeeding rate respectively with different sandfly species.…”

Rearing conditions of sandflies (Phlebotomus argentipes) has been improved. Bloodfed females were initially maintained at 21-23° C for 5-7 days before allowing them to oviposit at 26-28° C and a proportion of flies were directly allowed to oviposit at 26-28° C just after feeding to see their oviposition survival and subsequently the refeeding rate. It was found that when the flies were maintained following the former method gave better results. It is proposed to keep the bloodfed sandflies at a tempe rature lower than its suitable feeding temperature for a period longer than its oogenesis period and then to bring back the flies at slightly higher temperature, required for oviposition to get better result in oviposition survival and subsequently multiple feeding activity. Résumé : Amélioration des conditions d'élévage de Phlebotomus argentipes utile pour les études sur la dynamique de transmission des leishmanioses.Les femelles gorgées sont -tantôt maintenues 5 à 7 jours à 21-23° avant d'être mises à 26-28° pour permettre la pontetantôt mises à 26-28° aussitôt après le repas pour observer leur survie après la ponte et leur attitude à prendre un second repas.La première méthode est meilleure. Nous proposons de conserver les phlébotomes pendant l'oogenèse à une température plus basse que celle qui est favorable au repas, puis ensuite d'élever la tem pérature. La survie après la ponte et la possibilité de repas ulté rieurs sont améliorées.

“…P. perniciosus was recorded in southern Switzerland (Knechtli and Jenni, 1990) and Germany (Naucke et al, 2008), while P. perfiliewi and P. neglectus were more recently detected in some areas of Hungary (Farkas et al, 2011). Moreover, Phlebotomus (Transphlebotomus) mascittii has been recorded in Germany (Naucke and Pesson, 2000), Belgium (Depaquit et al, 2005) and Austria Poeppl et al, 2013).…”

“…Few experimental studies of L. infantum infection in hamsters have been reported, and the infection has been assessed using promastigote or amastigote forms, different inoculum doses and various administration routes (Knechtli and Jenni 1990;Bories et al 1998;Requena et al 2000).

Infection with Leishmania infantum promastigotes (group I) and amastigotes (group II) was evaluated over 32 weeks, using Syrian golden hamsters as an experimental model. Spleen cells strongly responded to the specific antigen at 12 (group I) and 16 weeks (group II) post-inoculation (p.i.) and lower stimulation index values coincided with the parasite burden peak. Western-blot analysis detected antibodies during the 1st week p.i. and the number of recognized proteins increased with the time of infection, reaching a maximum at the peak parasite burden. Histopathology revealed hypoplasia in spleen white pulp and the liver showed a periportal infiltration of inflammatory cells and small granulomas, becoming increasingly more severe as the infection developed. Both organs exhibited a secondary amyloid deposition at the end of the experiment, especially the spleen. In this study, progressive visceral disease was observed as in natural human and canine infections; however, the incubation period was longer in the promastigote than in the amastigote infection.Parasites L. infantum zymodeme MON-1 (MCAN/PT/94/IMT 205) promastigotes were obtained from the liver and the spleen of infected hamsters cultured in Novy-MacNeal-Nicolle (NNN) medium. The parasites were maintained at 24°C in HO-MEM medium (Gibco BRL) supplemented with 10% heat-inactivated fetal calf serum Parasitol
