Cardiac Lesions in 30 Dogs Naturally Infected With Leishmania infantum chagasi [PDF]

Veterinary Pathology, 2013
The hearts of 30 dogs naturally infected with Leishmania infantum chagasi were evaluated histologically and immunohistochemically. Myocardial lesions were detected in all dogs, including lymphoplasmacytic myocarditis (27/30), myonecrosis (24/30), increased interstitial collagen (22/30), lepromatous-type granulomatous myocarditis (7/30), fibrinoid ...

Para-kala-azar dermal leishmaniasis in a patient in Brazil: a case report

Revista da Sociedade Brasileira de Medicina Tropical
Visceral leishmaniasis is common in Brazil and is caused by Leishmania (Leishmania) infantum/chagasi. Post-kala-azar dermal leishmaniasis frequently follows visceral leishmaniasis caused by L.

Potential vectors of Leishmaniases in the Environmental Protection Area and Tinguá Federal Biological Reserve, Municipality of Nova Iguaçu, Rio de Janeiro, Brazil

Medical and Veterinary Entomology, Volume 40, Issue 2, Page 246-259, June 2026.
This study was to describe the composition of sand fly fauna, detect potential vectors of Leishmania spp. in the Tinguá district, an ATL endemic, Rio de Janeiro, Brazil. Seven species of vectorial importance in the epidemiological cycle of leishmaniasis was observed: Nyssomyia intermedia, Migonemyia migonei, Pintomyia fischeri, Psychodopygus hirsutus ...

Macrophage Polarization in the Skin Lesion Caused by Neotropical Species of Leishmania sp

Journal of Immunology Research, 2021
Macrophages play important roles in the innate and acquired immune responses against Leishmania parasites. Depending on the subset and activation status, macrophages may eliminate intracellular parasites; however, these host cells also can offer a safe ...

Evaluation of the Cutaneous Immunological Milieu Before and After Treatment With Meglumine Antimoniate in Dogs Naturally Affected by Leishmaniosis due to Leishmania infantum

Veterinary Dermatology, Volume 37, Issue 3, Page 455-463, June 2026.
Background: Canine leishmaniosis (CanL) is a zoonotic disease of variable severity. The typical immune response is driven by an exaggerated humoral immune response. Protective immunity is mediated by pro‐inflammatory cytokines that enhance macrophage leishmanicidal activity. Objective: To evaluate the cutaneous and the systemic immune responses as well

Leishmania infantum chagasi: A genome-based approach to identification of excreted/secreted proteins [PDF]

Experimental Parasitology, 2010
The parasitic protozoan, Leishmania, survives in harsh environments within its mammalian and sand fly hosts. Secreted proteins likely play critical roles in the parasite's interactions with its environment. As a preliminary identification of the spectrum of potential excreted/secreted (ES) proteins of Leishmania infantum chagasi (Lic), a causative ...

Factors Associated With the Emergence and Spread of Visceral Leishmaniasis in the State of São Paulo, Brazil

Zoonoses and Public Health, Volume 73, Issue 4, Page 348-357, June 2026.
ABSTRACT Introduction Visceral leishmaniasis (VL), once considered a rural disease in Brazil, has progressively urbanised, particularly in the state of São Paulo (SSP), where the first urban cases emerged after the detection of the vector Lutzomyia longipalpis in 1997.

Feline leishmaniosis due to Leishmania infantum (syn. L. chagasi)

Journal of the Hellenic Veterinary Medical Society, 2018
From the beginning of the 20th century, feline infections by at least eight different Leishmania species have been sporadically reported, worldwide. In the Mediterranean countries, feline infection imposed by L. infantum, the aetiological agent of canine leishmaniosis and human visceral and cutaneous leishmaniasis, is of particular importance, because ...
