The term leishmaniasis comprises of a group of diseases caused by different species of a protozoan called Leishmania. There are three main clinical forms of leishmaniasis: visceral leishmaniasis, cutaneous leishmaniasis, and mucocutaneous leishmaniasis. Exclusive involvement of the mucosa is very rare. We present a case of mucosal leishmaniasis located in the oral cavity. The only manifestation of leishmaniasis disease in the described case was the appearance of an oral lesion. Treatment was provided in the form of antimoniates (oral miltefosine and systemic sodium stibogluconate). A review of literature is made on the subject.

Introduction: Cutaneous Leishmaniasis (CL) is a zoonosis infection which is endemic in more than 100 countries in Asia, Africa, Europe and America. It was estimated that nearly 20 thousand of new cases are reported in Iran annually. This study aimed to investigate the impact of floods on the incidence of leishmaniasis in Golestan province (northeast of Iran) over nine years, from 2015 to 2023.

Bacterial infections commonly complicate cutaneous leishmaniasis (CL), worsening the disease and delaying healing. Despite this, there is a gap in research concerning the characteristics of pathogenic microorganisms associated in CL patients. This study aims to identify bacterial isolates and drug susceptibility patterns in CL patients.

The present investigation aims to develop a reactive oxygen species (ROS) and esterase-responsive biodegradable mannosylated polyurethane to effectively deliver the encapsulated antileishmanial drug amphotericin B (AmB) selectively to infected macrophage cells. Owing to suitable amphiphilic balance, the as-synthesized glycosylated polyurethane () with aryl boronic ester-based diol () moiety as ROS-trigger, water-soluble mannose pendants, and fluorescent 4,4-difluoro-4-bora-3a,4a-diaza--indacene (BODIPY) chain ends for bioimaging formed nanoaggregates in an aqueous medium as confirmed by H NMR spectroscopy, dynamic light scattering (DLS), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and critical aggregation concentration (CAC) measurements. Aided by two endogenous stimuli present in phagolysosome, ROS and esterase, AmB-encapsulated polymeric nanoaggregates as drug delivery vehicles achieved an efficient reduction of both and intracellular amastigote burden compared to the free AmB.

Leishmaniasis, a neglected tropical disease caused by Leishmania parasites, continues to pose global health challenges. Current treatments face issues like resistance, safety, efficacy, and cost. This review covers the discovery, mechanisms of action, clinical applications, and limitations of key antileishmanial agents: pentavalent antimonials, amphotericin B, miltefosine, paromomycin, and pentamidine.

Background: Leishmaniasis represents a significant parasitic disease with global health implications, and the development of an affordable and effective vaccine could provide a valuable solution. This study aimed to evaluate the immunogenicity of a DNA vaccine targeting Leishmania major specifically based on the Leishmania-activated C kinase (LACK) antigen, utilizing calcium phosphate nanoparticles (CaPNs) and chitosan nanoparticles (ChitNs) as adjuvants.
Methods: Seventy female BALB/c mice, aged 4-6 wk and weighing 20-22 g, were selected and divided into five groups, each consisting of 14 mice.
