objective(s): soluble leishmania antigens (sla) provide suitable protection against leishmaniasis in murine model when delivered by an appropriate delivery system. liposomes have been shown to be suitable vaccine delivery systems against leishmaniasis, however, the phospholipase-a (pla) activity of sla is a drawback to prepare a stable liposomal sla. one strategy to overcome this problem might ...

A vaccine against different forms of leishmaniasis should be feasible considering the wealth of information on genetics and biology of the parasite, clinical and experimental immunology of leishmaniasis, and the availability of vaccines that can protect experimental animals against challenge with different Leishmania species. However, there is no vaccine against any form of leishmaniasis for ge...

Leishmaniasis is a wide-spectrum disease caused by parasites from Leishmania genus. A well-modulated immune response that established after the long-lasting clinical cure of leishmaniasis can represent standard requirement for vaccine. Previous studies demonstrated (Viannia) naiffi causes benign and its antigens induce responses in vitro. In this work we aimed to identify immunodominant protein...

leishmaniases are a group of sand fly-borne diseases caused by protozoan parasites from species of leishmania genus. these diseases are reported in about 100 countries with a prevalence of 12 million people infected and incidence of 2 million people per year, putting approximately 350 million people at risk of the infections. leishmaniases are endemic and are considered as important public heal...

Leishmania is an obligate intracellular pathogen that invades phagocytic host cells. Approximately 30 different species of Phlebotomine sand flies can transmit this parasite either anthroponotically or zoonotically through their bites. Leishmaniasis affects poor people living around the Mediterranean Basin, East Africa, the Americas, and Southeast Asia. Affected regions are often remote and uns...

Leishmaniasis is a protozoan parasitic disease endemic to the tropical and subtropical regions of the world, with three major clinical forms, self-healing cutaneous leishmaniasis (CL), mucocutaneous leishmaniasis (MCL), and visceral leishmaniasis (VL). Drug treatments are expensive and often result in the development of drug resistance. No vaccine is available against leishmaniasis. Subunit Lei...

objective(s)cpg oligodeoxynucleotides (cpg odns) have been shown to have potent immunostimulatory adjuvant activity for a wide range of antigens. due to susceptibility of phosphodiester cpg odns (po cpg) to nuclease degradation, nuclease-resistant phosphorothioate cpg odns (ps cpg) were currently utilized in an in vivo model. in this study, according to some recently reported drawbacks with ps ...

Serine proteases are involved in several biochemical processes that are essential for the biology of pathogens, including Leishmania sp. Considering their importance, an interest in serine proteases for vaccine development against leishmaniasis has been raised. As targets, these enzymes have demonstrated a dual role in a vaccine against leishmaniasis, both protective and a counter-protective, d...

In this paper, we present spatial analysis of the association between all incidents cases of human Visceral Leishmaniasis and seropositive dogs, from 1994 to 1997 in Belo Horizonte, a large Brazilian city. We geocoded 158 human cases and 11,048 seropositive dogs and compared canine prevalence rates with Human Bayesian Incidence rates in the same areas. We also used Knox's test to evaluate the h...

objective(s): leishmaniasis is a complex parasitic disease that represents a major public health problem. despite numerous attempts over the past decades, yet there is no effective vaccine against human leishmaniasis probably due to the lack of suitable adjuvants. in this study, a first generation liposomal-based leishmania vaccine was developed using soluble leishmania major antigens (sla) and...
