Study on immunity of Leishmania major new crude antigen as a vaccine against leishmaniasis in out bred (resistant) and Balb/c (sensitive) mice

The aim of this study was to prepare a new formula of Leishmania major (L. major) crude antigen and evaluate its effect on immune system. For this purpose L. major promastigotes were cultured, harvested, washed, and resuspended in physiologic saline and the suspensions were dispersed in five equal batches. 0.1 ml of various doses of the cocktail antigen were injected intradermaly in three group...

a fundamental study of "histiriographic metafiction", and "literary genres", as introduced in "new historical philosophy", and tracing them in the works of julian barnes.

abstract a fundamental study of “historio-graphic metafiction” and “literary genres”, as introduced in “new historical philosophy”, and tracing them in the works of julian barnes having studied the two novels, the porcupine and arthur & george, by julian barnes, the researcher has applied linda hutcheon’s historio-graphic metafictional theories to them. the thesis is divided into five cha...

Role of imiquimod as adjuvant for vaccination against Leishmania major infection in BALB/c mice

Various adjuvants in combination with different antigens have been utilized as a vaccine candidate against leishmaniasis. However, the search for ideal adjuvants is still pursued due to the inefficiencies of current compounds. In the present study, the effect of imiquimod, as an adjuvant, is studied with soluble Leishmania antigens (SLA) in BALB/c mice. Four groups of mice were immunized with S...

Leishmania major-like antigen for specific and sensitive serodiagnosis of human and canine visceral leishmaniasis.

An antigen (LMS) prepared from Leishmania major-like promastigotes was used in an enzyme-linked immunosorbent assay (ELISA) for the diagnosis of human and dog visceral leishmaniasis. The results were compared with those from the indirect immunofluorescent antibody test (IFAT). A total of 1822 canine sera were tested, including sera from dogs with visceral leishmaniasis, transmissible venereal t...

In Vitro Evaluation of a Soluble Leishmania Promastigote Surface Antigen as a Potential Vaccine Candidate against Human Leishmaniasis

PSA (Promastigote Surface Antigen) belongs to a family of membrane-bound and secreted proteins present in several Leishmania (L.) species. PSA is recognized by human Th1 cells and provides a high degree of protection in vaccinated mice. We evaluated humoral and cellular immune responses induced by a L. amazonensis PSA protein (LaPSA-38S) produced in a L. tarentolae expression system. This was d...
