Diagnostic Challenges in Visceral Leishmaniasis in a 17‐Month‐Old Female: A Case Report

Clinical Case Reports, Volume 13, Issue 11, November 2025.
ABSTRACT Visceral leishmaniasis is an uncommon infectious disease. In this report, we present a case of VL in a 17‐month‐old child who presented with a fever and splenomegaly. After the patient failed to respond to several courses of antibiotics, a bone marrow aspirate confirmed the definitive diagnosis of VL, which was successfully treated with ...

Antileishmanial Activities of Carvacrol Nanoencapsulate in Biopolymeric Nanoparticles

Chemistry &Biodiversity, Volume 22, Issue 9, September 2025.
The study obtained biopolymeric nanoparticles containing carvacrol (NPCar) and evaluated their anti‐leishmanial activity. NPCar obtained presented physicochemical characteristics due to its ideal nanometric size and zeta potential, and low polydispersity index.

Topical Resiquimod Protects against Visceral Infection with Leishmania infantum chagasi in Mice [PDF]

Clinical and Vaccine Immunology, 2014
ABSTRACTNew prevention and treatment strategies are needed for visceral leishmaniasis, particularly ones that can be deployed simply and inexpensively in areas where leishmaniasis is endemic. Synthetic molecules that activate Toll-like receptor 7 and 8 (TLR7/8) pathways have previously been demonstrated to enhance protection against cutaneous ...

THE SERO-CONVERSION AND EVALUATION OF RENAL ALTERATIONS IN DOGS INFECTED BY Leishmania (Infantum) chagasi [PDF]

Revista do Instituto de Medicina Tropical de São Paulo, 2013
This study investigated the sero-conversion period in which dogs from endemic areas test positive for visceral leishmaniasis (VL) as well as the early post-infection period in which renal alterations are observed. Dogs that were initially negative for Canine Visceral Leishmaniasis (CVL) were clinically evaluated every three months by serological ...
