Vaccination with the Leishmania infantum ribosomal proteins induces protection in BALB/c mice against Leishmania chagasi and Leishmania amazonensis challenge

Microbes and Infection, 2010
Leishmania chagasi and Leishmania amazonensis are the etiologic agents of different clinical forms of human leishmaniasis in South America. In an attempt to select candidate antigens for a vaccine protecting against different Leishmania species, the efficacy of vaccination using Leishmania ribosomal proteins and saponin as adjuvant was examined in BALB/

A sensitive flow cytometric methodology for studying the binding of to canine peritoneal macrophages [PDF]

, 2005
The Leishmania promastigote-macrophage interaction occurs through the association of multiple receptors on the biological membrane surfaces. The success of the parasite infection is dramatically dependent on this early interaction in the vertebrate host,

Antibody response to sand fly saliva is a marker of transmission intensity but not disease progression in dogs naturally infected with Leishmania infantum [PDF]

, 2018
BACKGROUND: Antibody responses to sand fly saliva have been suggested to be a useful marker of exposure to sand fly bites and Leishmania infection and a potential tool to monitor the effectiveness of entomological interventions.

Prophylactic properties of a Leishmania-specific hypothetical protein in a murine model of visceral leishmaniasis [PDF]

, 2016
In this work, the effect of vaccination of a newly described Leishmania infantum antigenic protein has been studied in BALB/c mice infected with this parasite species.

Visceral Leishmaniasis During Pregnancy: A Case Report

Annals of Internal Medicine: Clinical Cases
Visceral leishmaniasis is a life-threatening disease endemic in tropical and subtropical regions and in the Mediterranean basin. Two species (Leishmania infantum/chagasi and Leishmania donovani) with different host reservoirs are responsible for visceral

Leishmania : taxonomie et phylogenèse ; applications éco-épidémiologiques [PDF]

, 1986
Un foyer de leishmaniose viscérale a été mis en évidence dans les Yungas du Département de La Paz. Le premier cas humain autochtone a pu être diagnostiqué en 1982 dans cette région. L'infection cutanée et viscérale du chien a été démontrée.

Detection of Leishmania infantum DNA in the non-parasitized lung of dogs with visceral leishmaniasis

BMC Veterinary Research, 2018

Sensitive and specific serodiagnosis of Leishmania infantum infection in dogs by using peptides selected from hypothetical proteins identified by an immunoproteomic approach [PDF]

, 2013
In Brazil, the percentage of infected dogs living in areas where canine visceral leishmaniasis (CVL) is endemic ranges from 10 to 62%; however, the prevalence of infection in dogs is probably higher than figures reported from serological studies.
