HRS/J Hairless mice have been investigated as an experimental model in cutaneous leishmaniasis induced by Leishmania (Leishmania) amazonensis. The animals were inoculated with 10(6) promastigotes into the right hind footpad and the course of infection was followed up for 30, 60 and 90 days. BALB/c mice were infected and used as control. Hairless mice were susceptible to L. (L.) amazonensis infe...
Leishmaniasis and trypanosomiasis are globally widespread parasitic diseases which have been responsible for high mortality rates. Since drugs available for their treatment are highly hepatotoxic, nephrotoxic and cardiotoxic, adherence to therapy has been affected. Thus, the search for new, more effective and safer drugs for the treatment of these diseases is necessary. Natural products have st...
Abstract Numerous studies have investigated the chemical composition and biological activities of essential oils from different Citrus species fruit peel, leaves flowers. This paper aims to investigate composition, larvicidal antileishmanial oil reticulata peel (CR-EO). CR-EO was obtained by hydrodistillation in a Clevenger-type apparatus its analyzed GC-MS GC-FID. Limonene (85.7%), ɣ-terpinene...
The development of new and cost-effective alternative therapeutic strategies to treat leishmaniasis has become a high priority. In the present study, the antileishmanial activity of Strychnos pseudoquina St. Hil. was investigated and pure compounds that presented this biological effect were isolated. An ethyl acetate extract was prepared, and it proved to be effective against Leishmania amazone...
E10-5A3 is a dhfr-ts- Leishmania major double knockout auxotrophic shown previously to induce substantial protection against virulent L. major infection in both genetically susceptible and resistant mice. We investigated the capacity of dhfr-ts- to protect against heterologous infection by L. amazonensis. The degree of protection was evaluated by immunization of BALB/c or C57BL/6 mice with E10-...
The purpose of this study was to characterize the immunopathological response in the skin of S. apella infected with Leishmania (L.) amazonensis and L. (V.) braziliensis parasites, the main causative agents of localized cutaneous leishmaniasis in South America. In infected animals, amastigote forms of L. (L.) amazonensis could be detected till 120 days postinfection (PI), while, in L. (V.) braz...
The currently used treatments for leishmaniasis, a neglected parasitic disease, are associated with several side effects, high cost and resistance of the Leishmania parasites. Here we evaluated in vitro and in vivo the antileishmanial activity of five antimalarial drugs against Leishmania amazonensis. Mefloquine was effective against promastigotes in axenic cultures and showed an IC50 (concentr...
