GENOTYPE CHARACTERIZATION OF Leishmania (Viannia) braziliensis ISOLATED FROM HUMAN AND CANINE BIOPSIES WITH AMERICAN CUTANEOUS LEISHMANIASIS

Revista do Instituto de Medicina Tropical de São Paulo, 2015
Introduction: American tegumentary leishmaniasis (ATL) can be caused by Leishmania (Viannia) braziliensis complex. The evolution of ATL initially results in lesions and can develop into disseminated or diffuse forms. The genetic diversity of L.

In Vitro Study on the Efficacy of Ziziphus vulgaris L. and Camellia sinensis (L.) Kuntze Extracts for Controlling Varroa destructor (Acari: Varroidae) in Apis mellifera (Hym.: Apidae)

Veterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Extracts of Ziziphus vulgaris and Camellia sinensis applied in wooden cages increase Varroa destructor mortality (5–25 µL/L air) while minimizing Apis mellifera harm, offering a sustainable mite control method. ABSTRACT Background Ziziphus vulgaris L.

Karyotype plasticity in NeotropicalLeishmania: an index for measuring genomic distance amongL. (V.) peruvianaandL. (V.) braziliensispopulations

Parasitology, 1995
A method for phenetic analysis of karyotype data has been developed forLeishmaniapopulations. Measurement of size difference between chromosomes recognized by a given DNA probe in different isolates led to the formulation of a Chromosome Size Difference Index (CSDI).

Evaluating the spatial distribution of Leishmania parasites in Colombia from clinical samples and human isolates (1999 to 2016).

PLoS ONE, 2019
In Colombia, nine species of parasites of the genus Leishmania circulate in more than 20 sand fly species, putting at risk of contracting the disease approximately 60% of the population.

Mucosal leishmaniasis: A forgotten disease, description and identification of species in 50 Colombian cases

Biomédica: revista del Instituto Nacional de Salud, 2019
Introduction: Mucosal leishmaniasis has a progressive course and can cause deformity and even mutilation in the affected areas. It is endemic in the American continent and it is mainly caused by Leishmania (Viannia) braziliensis. Objective: To describe a

Comparison of gene expression patterns among Leishmania braziliensis clinical isolates showing a different in vitro susceptibility to pentavalent antimony [PDF]

, 2017
Introduction. Evaluation of Leishmania drug susceptibility depends on in vitro SbV susceptibility assays, which are labour-intensive and may give a biased view of the true parasite resistance. Molecular markers are urgently needed to improve and simplify

The proinflammatory activity of recombinant serum amyloid A is not shared by the endogenous protein in the circulation.

, 2010
OBJECTIVE: Elevated serum levels of the acute-phase protein serum amyloid A (SAA) are a marker for active rheumatoid arthritis (RA), and SAA can also be found in the tissues of patients with active RA.

Library of Seleno-Compounds as Novel Agents against Leishmania Species [PDF]

, 2017
The in vitro leishmanicidal activities of a series of 48 recently synthesized selenium derivatives against Leishmania infantum and Leishmania braziliensis parasites were tested using promastigotes and intracellular amastigote forms.

In Situ Evaluation of Macrophage Populations and Inflammasome Components in Cutaneous and Mucocutaneous Leishmaniasis

Parasite Immunology, Volume 47, Issue 9, September 2025.
ABSTRACT American tegumentary leishmaniasis (ATL) affects the skin and mucous membranes, with a spectrum shaped by Th1/Th2 responses. This study investigated inflammasome activation in correlation with macrophage subpopulations, tissue parasitism, and histological changes in cutaneous and mucocutaneous leishmaniasis. We assessed inflammasome activation,

Cell migration induced by Leishmania (Leishmania) amazonensis, Leishmania (Leishmania) major and Leishmania (Viannia) braziliensis into the peritoneal cavity of BALB/c mice

Journal of Venomous Animals and Toxins including Tropical Diseases, 2010
In American cutaneous leishmaniasis, the initial infection phase is characterized by recruitment of neutrophils and monocytes. The migration of these cells in response to the presence of Leishmania in the peritoneum of affected animals remains unclear ...
