Background and purpose: Toxoplasma gondii (T. gondii) as a causative agent of toxoplasmosis, is an obligate intracellular parasite which is excreted by the cat's feces. Efforts have been made for the development of toxoplasmosis vaccine, but none led to developing a vaccine with protective immune response to the parasite. Adjuvants are essential for vaccine formulation to create strong immune r...
Background: Pseudomonas aeruginosa, an opportunistic pathogen, is a common cause of healthcare-associated infections in immunocompromised individuals. The rapid emergence of multidrug-resistant strains has made P. aeruginosa infections progressively difficult to treat. In this study we evaluated the effect of a chimeric protein containing a P. aeruginosa PilQ fragment and the PilA disulfide loo...
The importance of Fc-dependent effector functions of Abs induced by vaccination is increasingly recognized. However, vaccination of mice against HIV envelope (Env) induced a skewed Th cell response leading to Env-specific Abs with reduced effector function. To overcome this bias, GagPol-specific Th cells were harnessed to provide intrastructural help for Env-specific B cells after immunization ...
Mastitis is a one of the major diseases of dairy animals. Staphylococcus aureus is the most common microorganism associated with this dairy scourge. Cure rates of mastitis associated with this pathogen are appallingly low. Biofilm is an important virulence factor and immunogenic structure of S. aureus that makes it resistant to phagocytosis and antibiotics. Reports on the efficacy of vaccine pr...
The effects of different levels of alcoholic chicory (Cichorium intybus L.) extract were investigated on performance, cellular and humoral immunity in 200 one-day chicks (Ross 308) in a completely randomized design with 5 treat ments and 4 replicates and 10 chicks per replicate. The treatment groups received 0 (control), 0.5, 1, 1.5 and 2 ml/Lit of alcoholic chicory extract, (provided from Ch...
Adenoviral transfer of human apo A-I in Balb/c mice induces a strong humoral immune response against the transgene product when expression is driven from the ubiquitously active CMV promoter but induces no immune response when driven by the hepatocyte-specific 256-base pair apo A-I promoter. Here the hypothesis was tested, which is that the humoral immune response against the circulating transg...
