Effect of flood on the cutaneous leishmaniasis incidence in northeast of Iran: an interrupted time series study.
BMC Infect Dis

Department of Epidemiology, School of Public Health, Shahroud University of Medical Sciences, Shahroud, Iran.
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.

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.

A light and electron microscopic study of skin biopsies taken from 9 patients with ulcerative leishmaniasis of both sexes aged from 14 to 26 years in the territory of the Republic of Azerbaijan was carried out. Based on clinical, morphological and electron microscopic parameters, all patients were diagnosed with ulcerative cutaneous anthroponotic leishmaniasis (Leishmania (L.) tropica).

Article Synopsis
- Leishmania (Viannia) braziliensis causes various types of leishmaniasis, and the study investigates how different subpopulations (Thor03, Thor10, Thor22) affect disease progression in BALB/c mice.
- The research found that after three weeks of infection, Thor03 and Thor10 led to larger lesions and influenced immune response markers, showing lower IL-12 and TNF levels, while Thor10 had the highest IL-10 levels.
- The study concluded that these subpopulations might lead to mild footpad lesions but can persist in lymph nodes, highlighting differences in infection patterns and immune responses among the subpopulations.
