First molecular detection of Leishmania (Leishmania) infantum chagasi in a domestic cat (Felis catus) from an urban area in eastern Amazon [PDF]

Journal of Venomous Animals and Toxins including Tropical Diseases, 2023
Background: Domestic cats have been implicated as accidental hosts of Leishmania sp. However, in recent years, the recurrent description of new cases in endemic and nonendemic areas draw attention to the potential epidemiological role of cats as ...

Brain Involvement in Leishmaniasis. [PDF]

Cell Biochem Funct
ABSTRACT Leishmaniasis is a neglected tropical disease caused by infection with the protozoan parasite Leishmania and it is a significant global health problem. The disease has a wide clinical spectrum, from tegumentary leishmaniasis (TL) that encompasses cutaneous (CL), mucosal (ML) and cutaneous‐diffuse (CDL) forms, to the potentially fatal systemic ...

Thymus and Leishmania at the Crossroads: Autoimmunity and Cancer. [PDF]

Immunology
Conceptual ‘Crossroads Model’ linking Leishmania, thymic infection and immune dysregulation: an integrative model is proposed in which Leishmania infection disrupts thymic architecture and stromal–thymocyte interactions. These alterations converge to promote defective tolerance, increased autoimmune risk and a microenvironment permissive to malignant ...

Peptides as a Therapeutic Alternative Against Leishmaniasis: A Scoping Review. [PDF]

Chem Biol Drug Des
This scoping review of 79 studies identified 231 antimicrobial peptides with anti‐Leishmania activity, including natural‐derived and synthetic peptides (inspired by natural sources or developed through rational design). Most were evaluated in vitro against promastigote and/or amastigote forms, with synthetic peptides showing a more promising effect ...

Leishmaniasis Transmission Risk at the Forest-Peridomestic Interface in an Area of Southern Sinaloa, Mexico: Entomological, Molecular, and Climatic Evidence. [PDF]

J Parasitol Res
Leishmaniasis, caused by Leishmania spp. and transmitted by phlebotomine sand flies, affects almost 1,000,000 people annually across more than 90 countries. In Mexico, growing evidence of locally acquired transmission in northwestern states makes ecoepidemiological work increasingly urgent.

Assessment of Leishmania exposure in blood donors from a non-endemic urban area: A study in São Paulo. [PDF]

Vox Sang
Abstract Background and Objectives According to the World Health Organization, more than 1 billion people are at risk of leishmaniasis in over 89 countries. Environmental changes such as deforestation, urban expansion and climate change facilitate the spread of sand fly vectors and reservoirs, increasing disease transmission.

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

Vet Dermatol
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

Cortisol Regulates PD-1 and IL-12 in Canine Leishmaniasis. [PDF]

Parasite Immunol
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.

Cutaneous Leishmaniasis Mimicking a Nasal Tumor: A Case Report. [PDF]

Case Rep Infect Dis
Leishmaniasis is a disease caused by Leishmania protozoa that is transmitted to the patient by sand flies. Depending on the Leishmania species, the disease can present with cutaneous, mucosal, or multiorgan involvement. Cutaneous leishmaniasis can present with diverse clinical manifestations mimicking other diseases.

Immucillins Impair Leishmania (L.) infantum chagasi and Leishmania (L.) amazonensis Multiplication In Vitro [PDF]

PLoS ONE, 2015
Chemotherapy against visceral leishmaniasis is associated with high toxicity and drug resistance. Leishmania parasites are purine auxotrophs that obtain their purines from exogenous sources.
