Competence of the Human Host as a Reservoir forLeishmania chagasi [PDF]

The Journal of Infectious Diseases, 2000
The failure of control programs for visceral leishmaniasis (VL) that depend on elimination of infected dogs suggests that other reservoir hosts may participate in the transmission cycle. To determine whether persons infected with Leishmania chagasi can infect the vector sand fly, laboratory-reared Lutzomyia longipalpis were allowed to feed on Brazilian

Cortisol Regulates PD‐1 and IL‐12 in Canine Leishmaniasis

Parasite Immunology, Volume 48, Issue 2, February 2026.
ABSTRACT Canine visceral leishmaniasis (CanL) is a tropical zoonosis caused by Brazil's protozoan Leishmania (L.) infantum. Disorders in the hypothalamic–pituitary–adrenal (HPA) axis have been reported in human and experimental visceral leishmaniasis, but not yet in canine leishmaniasis.

Autochthonous case of Canine Visceral Leishmaniasis in a non-endemic area in Minas Gerais, Brazil

Pesquisa Veterinária Brasileira
: Visceral Leishmaniasis by Leishmania infantum chagasi is an endemic zoonosis present in many areas of Brazil. This parasite needs reservoirs for maintenance of the infection and the presence of dogs in urban areas is a key factor for the spread of ...

Chronic pericarditis in a naturally Leishmania (Leishmania) chagasi infected dog

Brazilian Journal of Veterinary Pathology, 2009
Visceral Leishmaniasis is an infection disease of chronic evolution caused by the protozoan Leishmania sp. The main clinical manifestations in dogs are anemia, progressive weight loss, lymphadenopathy, hepatomegaly, and cutaneous lesions. The heart involvement in visceral leishmaniasis has been rarely reported.

The transmission of Leishmania infantum chagasi by the bite of the Lutzomyia longipalpis to two different vertebrates

Parasites & Vectors, 2012
Background Sandflies are vectors of Leishmania, the causative agent of leishmaniasis in mammalian hosts, including humans. The protozoan parasite is transmitted by the sandfly bite during salivation that occurs at the moment of blood feeding.

Reproduction of Leishmania (Leishmania ) infantum chagasi in conditioned cell culture growth medium [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 2006
Leishmanias can be produced by inoculation in conditioned McCoy cell culture growth medium (CGM). Leishmania (Leishmania) infantum chagasi (100 parasites) grown in NNN medium was inoculated in 2.5 mL CGM, kept in plates (24 wells) and its multiplication was observed for five days (120 hours).

Visualisation of Leishmania donovani fluorescent hybrids during early stage development in the sand fly vector. [PDF]

, 2011
BACKGROUND: The Leishmania protozoan parasites cause devastating human diseases. Leishmania have been considered to replicate clonally, without genetic exchange.

Sex in Immune Cells and Parasitic Diseases — A Complex Relationship

Immunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Epidemiological studies consistently show that many parasitic diseases affect males more frequently than females. These disparities are multifactorial, arising partly from gender‐specific behaviors that influence exposure risk and health‐seeking practices, especially in low‐ and middle‐income countries. Increasing evidence also highlights that

Leishmania chagasi heparin-binding protein: Cell localization and participation in L. chagasi infection

Molecular and Biochemical Parasitology, 2015
Visceral leishmaniasis is a fatal human disease caused by the intracellular protozoan parasite Leishmania chagasi that is captured by host cells in a process involving classics receptors mediated phagocytosis. The search for molecules involved in this process is important to design strategies to disease control.
