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.

Article Synopsis
  • Alpha-Gal syndrome (AGS) is an allergy caused by specific IgE antibodies reacting to a carbohydrate called galactose-a-1.3-galactose, primarily triggered by tick bites that introduce a-Gal antigens.
  • Individuals with AGS can have allergic reactions to mammal meat and some medical products, which can lead to severe symptoms like rashes, nausea, and even life-threatening situations.
  • The unique characteristics of AGS, including delayed reactions and specific immune responses, distinguish it from other food allergies, but the exact mechanisms behind these immune responses are still not completely understood.

Article Synopsis
  • - The study focuses on the rising incidence of cutaneous leishmaniasis (CL) in Türkiye due to migration and environmental changes, noting that it’s appearing in places where it was previously unknown, leading to misdiagnosis by physicians unfamiliar with the disease.
  • - Researchers performed a retrospective analysis of 12 CL cases diagnosed from 2013 to 2022, looking at clinical presentation, pre-diagnosis, histopathological findings, and DNA analysis to confirm species involved.
  • - Findings show that only 58.3% of cases considered CL in their pre-diagnosis; others were misdiagnosed, often as skin tumors, with patients presenting non-healing skin lesions that required further evaluation.

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.

Objective: RNA virus was detected the first time in the New World species. Recent studies were also showed the presence of RNA virus 2 (LRV2) in Old Word species including Turkish and isolates. This study aimed to increase the sensitivity of qPCR with a modification in the denaturation step of cDNA preparation protocol.

Introduction: Phlebotomine sand flies (Diptera: Psychodidae) are known as the vector of diseases such as leishmaniasis, bartonellosis and viral diseases. The aim of this study is to detect the host feeding pattern of sand flies in the endemic areas for leishmaniasis in Turkey (Antalya, Kayseri) and Northern Cyprus (TRNC) as well as the presence of Leishmania DNA in the specimens.

Methods: One-hundred seventy-six blood-fed sand fly specimens were examined for blood meal analysis.

Due to its geographical location, Muğla province is one of the most frequently used places by refugees. Although leishmaniasis have been previously reported in this region, there is a lack of information on the etiological agent and possible vectors. The main objectives of this study were; i) to investigate the sand fly fauna, ii) to reveal the natural Leishmania spp.

Leishmaniasis is a parasitic disease infecting animals and humans. Two clinical forms (Visceral and cutaneous leishmaniasis) and four species are reported to be present in Turkey. Several studies have investigated canine and human leishmaniasis in Turkey but no study was performed to screen the infection among wild rodents, so far.

Ticks are obligate hematophagous ectoparasites as well as mechanical and biological vectors of a wide variety of microbial pathogens. To date, 19 tick-borne diseases have been reported from Turkey. In this study, ticks collected from Aydın, İzmir and Şanlıurfa provinces of Turkey were identified using morphological and molecular methods.

Background: Leishmania RNA virus (LRV) is a double-stranded RNA (dsRNA) virus infecting some Leishmania strains and triggering a destructive hyperinflammatory response in mammalian hosts in the New World. There is limited knowledge of the presence of this virus in Old World Leishmania species and its role in the outcome of the disease. We aimed to investigate the presence of LRV in Leishmania species/strains from Turkey.
