Anatomical Vascular Differences and -Induced Vascular Morphological Changes Are Associated with a High Parasite Load in the Skin of Dogs Infected with .

Canine visceral leishmaniasis (CVL), caused by the protozoan , affects several organs, including the skin. Dogs are considered the major domestic reservoir animals for leishmaniasis, and through their highly parasitized skin, they can serve as a source of infection for sandfly vectors. Therefore, studies of the skin parasite-host relationship can contribute to the understanding of the infectious dissemination processes of parasites in the dermis and help to identify targets for diagnosis and treatment.

Refinement of the rKLi8.3-Based Serodiagnostic ELISA Allows Detection of Canine Leishmaniosis in Dogs with Low Antibody Titers.

The diagnosis of canine leishmaniasis (CanL) still represents a challenge due to the variable clinical manifestations and the large number of asymptomatic dogs. Serological tests are most commonly used to detect infected animals, revealing anti- antibodies, mainly of the IgG isotype. Recently, a new diagnostic antigen, rKLi8.

Advancement in Leishmaniasis Diagnosis and Therapeutics.

Leishmaniasis is a complex of clinical manifestations that affects thousands of people in the world each year according to WHO [...

Insights from Leishmania (Viannia) guyanensis in vitro behavior and intercellular communication.

Background: Pentavalent antimonial-based chemotherapy is the first-line approach for leishmaniasis treatment and disease control. Nevertheless antimony-resistant parasites have been reported in some endemic regions. Treatment refractoriness is complex and is associated with patient- and parasite-related variables.

Colonization and genetic diversification processes of Leishmania infantum in the Americas.

Leishmania infantum causes visceral leishmaniasis, a deadly vector-borne disease introduced to the Americas during the colonial era. This non-native trypanosomatid parasite has since established widespread transmission cycles using alternative vectors, and human infection has become a significant concern to public health, especially in Brazil. A multi-kilobase deletion was recently detected in Brazilian L.
