Experimental infection and transmission of Leishmania by Lutzomyia cruzi (Diptera: Psychodidae): Aspects of the ecology of parasite-vector interactions. [PDF]

PLoS Neglected Tropical Diseases, 2017
Several parameters should be addressed before incriminating a vector for Leishmania transmission. Those may include its ability to become infected by the same Leishmania species found in humans, the degree of attractiveness for reservoirs and humans and ...

The Paradox of a Phagosomal Lifestyle: How Innate Host Cell-Leishmania amazonensis Interactions Lead to a Progressive Chronic Disease

Frontiers in Immunology, 2021
Intracellular phagosomal pathogens represent a formidable challenge for innate immune cells, as, paradoxically, these phagocytic cells can act as both host cells that support pathogen replication and, when properly activated, are the critical cells that ...

Vaccination of C57BL/10 mice against cutaneous leishmaniasis using killed promastigotes of different strains and species of Leishmania Vacinação de camundongos C57BL/10 contra leishmaniose com promastigotas mortas de diferentes cepas e espécies de Leishmania

Revista da Sociedade Brasileira de Medicina Tropical, 2002
Antigenic extracts from five Leishmania stocks were used to vaccinate C57BL/10 mice. The Leishvacin® and PH8 monovalent vaccine yielded the highest IFN-gamma levels in the supernatants of spleen cell culture from vaccinated animals.

Leishmania (Leishmania) amazonensis Infection in Mice Treated With FTY720

Transplantation Proceedings, 2010
In transplantation, parasite diseases are transmitted from the donor, or appear as de novo infections, or activate from a dormant insource as a consequence of immunosuppression. Clinical findings have shown that an intact immune system is crucial to prevent recurrence of Leishmania infection.

Selective effects of Euterpe oleracea (açai) on Leishmania (Leishmania) amazonensis and Leishmania infantum

Biomedicine & Pharmacotherapy, 2018
Leishmania (Leishmania) amazonensis and Leishmania infantum (=Leishmania chagasi) are protozoa that cause American cutaneous and visceral leishmaniasis, respectively. These diseases show a high incidence in developing countries such as Brazil. The treatments used for leishmaniasis are still limited due to their high cost and toxicity.
