Infection of Human Neutrophils With Leishmania infantum or Leishmania major Strains Triggers Activation and Differential Cytokines Release

open access: yesFrontiers in Cellular and Infection Microbiology, 2019
Leishmaniases are neglected diseases, caused by intracellular protozoan parasites of the Leishmania (L.) genus. Although the principal host cells of the parasites are macrophages, neutrophils are the first cells rapidly recruited to the site of parasites

Fatal Outcome of Membranoproliferative Glomerulonephritis in a Patient With Hidden Visceral Leishmaniasis

open access: yesCase Reports in Infectious Diseases, Volume 2025, Issue 1, 2025.
Background: Visceral leishmaniasis (VL) is a systemic parasitic disease with diverse clinical manifestations, primarily affecting the spleen, liver, and bone marrow. While renal involvement in VL is well documented, it is often mild and resolves with effective treatment.

Vaccination with Leishmania infantum Acidic Ribosomal P0 but Not with Nucleosomal Histones Proteins Controls Leishmania infantum Infection in Hamsters

open access: yesPLOS Neglected Tropical Diseases, 2015
Several intracellular Leishmania antigens have been identified in order to find a potential vaccine capable of conferring long lasting protection against Leishmania infection. Histones and Acid Ribosomal proteins are already known to induce an effective immune response and have successfully been tested in the cutaneous leishmaniasis mouse model.

Tissue Cytokine Responses in Canine Visceral Leishmaniasis [PDF]

open access: yes, 2001
To elucidate the local tissue cytokine response of dogs infected with Leishmania chagasi, cytokine mRNA levels were measured in bone marrow aspirates from 27 naturally infected dogs from Brazil and were compared with those from 5 uninfected control ...

Infectivity of Aflagellar Epimastigotes of Trypanosoma caninum in the DH82 Cell Line and Mouse Peritoneal Macrophages

open access: yesJournal of Parasitology Research, Volume 2025, Issue 1, 2025.
Background:Trypanosoma caninum presents aflagellar and flagellar epimastigote, trypomastigote, and spheromastigote forms in axenic cultures. Attempts to utilize trypomastigote forms of T. caninum to develop in vitro and in vivo infection models have failed. To investigate the infection potential of aflagellar epimastigotes, T.

Biological activities and chemical composition of methanolic extracts of selected Autochthonous microalgae strains from the Red Sea [PDF]

open access: yes, 2015
Four lipid-rich microalgal species from the Red Sea belonging to three different genera (Nannochloris, Picochlorum and Desmochloris), previously isolated as novel biodiesel feedstocks, were bioprospected for high-value, bioactive molecules.

Distinct gene expression patterns in vector-residing Leishmania infantum identify parasite stage-enriched markers

open access: yesbioRxiv, 2019
Promastigotes of Leishmania infantum undergo a series of extracellular developmental stages inside the natural sand fly vector Lutzomyia longipalpis to reach the infectious stage, the metacyclic promastigote.

Leishmaniasis in Northern Morocco: Predominance of Leishmania infantum Compared to Leishmania tropica

open access: yesBioMed Research International, 2019
In Morocco, Leishmania infantum species is the main causative agents of visceral leishmaniasis (VL). However, cutaneous leishmaniasis (CL) due to L. infantum has been reported sporadically. Moreover, the recent geographical expansion of L.

Transmission potential of paromomycin-resistant Leishmania infantum and Leishmania donovani

open access: yesJournal of Antimicrobial Chemotherapy, 2019
AbstractObjectivesFormer studies demonstrated quick selection of paromomycin resistance for Leishmania infantum and Leishmania donovani accompanied by increased fitness. The present study aimed to interpret these findings in an epidemiological context by comparing infection of WT and experimentally derived paromomycin-resistant strains in the sand fly ...

Miltefosine induces metacaspase and PARP genes expression in Leishmania infantum

open access: yesBrazilian Journal of Infectious Diseases, 2011
Objectives: Apoptosis is the process of programmed cell death (PCD) that occurs in both animal and plant cells. Protozoan parasites possess metacaspase and these caspase-related proteases could be involved in the PCD pathways in these organisms ...
