Management of Canine Leishmaniasis and the Treatment Trends of Veterinarians in Aegean Region of Türkiye: A Questionnaire-based Survey.

Objective: Canine leishmaniasis (CanL) is an important veterinary and public health problem in Mediterranean countries. Although CanL and vector sandflies are widespread in the study area, there are no standardized diagnostic and treatment methods followed by private clinics. This study aimed to survey (i) the treatment, diagnosis, and control measures preferred by veterinarians, (ii) compare the differences in the first-step diagnostic tests applied, and (iii) identify differences in the guidance for CanL.

Performance evaluation of nine reference centers and comparison of DNA extraction protocols for effective surveillance of Leishmania-infected Phlebotomine sand flies: Basis for technical recommendations.

Background: Leishmaniasis, caused by Leishmania protozoan parasites transmitted by Phlebotomine sand flies, is a significant public health concern in the Mediterranean basin. Effective monitoring of Leishmania-infected sand flies requires standardized tools for comparing their distribution and infection prevalence. Consistent quantitative real-time PCR (qPCR) parameters and efficient DNA extraction protocols are crucial for reliable results over time and across regions.

Mosquito populations originating from nonendemic areas have the potential to transmit recently emerging Japanese encephalitis virus genotype IV.

Japanese encephalitis virus (JEV) genotype IV (GIV) is one of the least common and most neglected genotypes worldwide, having been identified only on a few Indonesian islands until it was recently found to be the cause of outbreaks that occurred in several Australian states in early 2022. Given the limited availability of information, the vector range for JEV GIV remains unknown; thus, understanding this range could prove invaluable for future prevention efforts in new areas. Herein, we experimentally exposed four mosquito colonies originated from various countries with no previous reports of GIV to JEV GIV strain 19CxBa-83-Cv, which was isolated from Theobald collected in Bali in 2019.

Genetic diversity and epidemiological insights into cutaneous leishmaniasis in Pakistan: a comprehensive study on clinical manifestations and molecular characterization of Leishmania species.

Cutaneous leishmaniasis (CL) stands out as a significant vector-borne endemic in Pakistan. Despite the rising incidence of CL, the genetic diversity of Leishmania species in the country's endemic regions remains insufficiently explored. This study aims to uncover the genetic diversity and molecular characteristics of Leishmania species in CL-endemic areas of Baluchistan, Khyber Pakhtunkhwa (KPK), and Punjab in Pakistan.

Entomological surveillance and spatiotemporal risk assessment of sand fly-borne diseases in Cyprus.

Visceral and cutaneous leishmaniases are important public health concerns in Cyprus. Although the diseases, historically prevalent on the island, were nearly eradicated by 1996, an increase in frequency and geographical spread has recently been recorded. Upward trends in leishmaniasis prevalence have largely been attributed to environmental changes that amplify the abundance and activity of its vector, the phlebotomine sand flies.

Comparative analysis of the severity and progression of cutaneous leishmaniasis caused by Leishmania tropica in untreated and glucantime-treated patients.

Millions of people worldwide are affected by cutaneous leishmaniasis (CL), a disease that has a significant impact on morbidity and mortality. Understanding the immune responses responsible for tissue damage or the process of lesion healing plays a pivotal role in shaping optimal treatment strategies. In this study, we investigated immunological phenotypes for three groups: glucantime treated (n = 30) and untreated (n = 30) CL patients infected with Leishmania tropica (L.

Autochthonous infections were reported in the scientific literature from 22 countries, including 13 and 21 countries reporting human and animal infections, respectively.

Arthropod vectors of disease agents: Their role in public and veterinary health in Turkiye and their control measures.

Mosquitoes, sandflies, and ticks are hematophagous arthropods that pose a huge threat to public and veterinary health. They are capable of serving as vectors of disease agents that can and have caused explosive epidemics affecting millions of people and animals. Several factors like climate change, urbanization, and international travel contribute substantially to the persistence and dispersal of these vectors from their established areas to newly invaded areas.

Immunoinformatics Approach to Design a Multi-Epitope Vaccine against Cutaneous Leishmaniasis.

Cutaneous Leishmaniasis (CL), a neglected vector-borne disease caused by protozoan parasite Leishmania major (), is a major public health concern, and the development of new strategies to reduce the disease incidence has become a top priority. Advances in immunoinformatics and in-silico epitope prediction could be a promising approach to designing a finest vaccine candidate. In this study, we aimed to design a peptide-based vaccine against CL using computational tools and identified ten B-cell-derived T-cell epitopes from the glycoprotein gp63 of .

Leishmania kinetoplast DNA contributes to parasite burden in infected macrophages: Critical role of the cGAS-STING-TBK1 signaling pathway in macrophage parasitemia.

Leishmania parasites harbor a unique network of circular DNA known as kinetoplast DNA (kDNA). The role of kDNA in leishmania infections is poorly understood. Herein, we show that kDNA delivery to the cytosol of infected THP-1 macrophages provoked increased parasite loads when compared to untreated cells, hinting at the involvement of cytosolic DNA sensors in facilitating parasite evasion from the immune system.

The Effect of BTK Inhibitor Ibrutinib on Leishmania infantum Infection In Vitro.

Purpose: Leishmaniasis is a neglected infectious disease affecting millions of people worldwide. Visceral leishmaniasis (VL), caused by Leishmania infantum and Leishmania donovani, is one of the main clinical forms of the disease and fatal if not treated promptly and properly. Despite being available for the last 70 years, current drugs used in the treatment of leishmaniasis have serious problems as they have high toxicity, require long-term administration and cause serious side-effects, leading to the emergence of resistant and relapse cases.

Multiparametric approach to assess the disease severity and progression of cutaneous leishmaniasis infection.

The pathophysiology of Cutaneous Leishmaniasis (CL), an infection caused by Leishmania tropica (L. tropica) and Leishmania major (L. major) is primarily determined by inflammation-mediated immune cells.
