Natural sandfly infection by Leishmania spp. in an area endemic for American cutaneous leishmaniasis was analyzed using multiplex polymerase chain reaction (PCR). The sandflies were captured using Falcão light traps in an endemic area of the municipality of Doutor Camargo during March, April, and June 2008. In total, 1803 females were analyzed; 1755 were Nyssomyia neivai (Pinto) and 48 were Nyssomyia whitmani (Antunes and Coutinho). Multiplex PCR analyses using MP3H-MP1L and 5Llcac-3Llcac primers showed the presence of Leishmania (Viannia) spp. in 4/181 pools of sandflies, all Ny. neivai, that is, a minimal infection rate of 0.22%. This study showed, for the first time, the presence of DNA of Leishmania (Viannia) spp. in Ny. neivai. This suggests the existence of natural infection by Leishmania (Viannia) spp. in Ny. neivai in the state of Paraná. Multiplex PCR is an important tool in the detection of Leishmania infection in sandflies.

Leishmania is a genus of the family Trypanosomatidae that unites obligatory parasitic flagellates causing a variety of vector-borne diseases collectively called leishmaniasis. The symptoms range from relatively innocuous skin lesions to complete failures of visceral organs. The disease is exacerbated if a parasite harbors Leishmania RNA viruses (LRVs) of the family Pseudototiviridae.

This study aimed to evaluate differences in the production of reactive oxygen species (ROS) by peripheral blood neutrophils in healthy dogs, dogs with superficial pyoderma, and dogs with sterile neutrophilic dermatitis using the nitroblue tetrazolium (NBT) reduction test. Additionally, the study assessed the potential of the NBT reduction test as a diagnostic tool to differentiate between these clinical conditions. A total of 28 dogs were divided into three groups: healthy (n = 10), superficial pyoderma (n = 10), and sterile neutrophilic dermatitis (n = 8).

is a vector of , the causative agent of cutaneous leishmaniasis. This study assessed the abundance and distribution of in different habitats and human houses situated at varying distances from hyrax (reservoir host) dwellings, in Wolaita Zone, southern Ethiopia. Sandflies were collected from January 2020 to December 2021 using CDC light traps, sticky paper traps, and locally made emergence traps.

: The rise of drug-resistant strains presents a significant challenge in the treatment of Leishmaniasis, a neglected tropical disease. Extracellular vesicles (EVs) produced by these parasites have gained attention for their role in drug resistance and host-pathogen interactions. : This study developed and applied a novel lipidomics workflow to explore the lipid profiles of EVs from three types of drug-resistant strains compared to a wild-type strain.

Visceral Leishmaniasis, caused by is the second most deadly parasitic disease, causing over 65,000 deaths annually. Synthetic drugs available in the market, to combat this disease, have numerous side effects. In this backdrop, we aim to find safer antileishmanial alternatives with minimal side effects from mushrooms, which harbour various secondary metabolites with promising efficacy.
