Special Issue Information

Dear Colleagues,

Anthropogenic movements result in modifications of wild natural habitats, such as the destruction of forest areas, the introduction of domestic animals, and the improvising of sanitation conditions. These changes, associated with global warming, can lead to the uncontrolled proliferation and dispersion of arthropod vectors of parasitic infectious diseases, such as malaria, Chagas disease, and leishmaniasis. Others parasitic diseases are associated with poor sanitation conditions, such as giardiasis, toxoplasmosis, and diseases caused by helminths and flatworms. As a result of the diversity of biomes, the investigation of eco-epidemiological and evolutionary relationships among parasites is important for the detection, prevention, and clinical management of parasitic infectious diseases.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pathogens is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Leishmaniasis is difficult to control due to clinical and vector diversity associated with the complex life cycle of Leishmania parasites, which are transmitted by sandflies. This study investigated the presence of Leishmania DNA in sandfly vectors, their blood meal sources, and their distribution in relation to environmental and climatic variables in four municipalities in Piauí state, Brazil. Between 2020 and 2022, sandflies were collected, morphologically identified, and analyzed for the presence of parasite DNA and blood meal sources (PCR, sequencing). Climate data were correlated with the density of collected insects. Among the 10,245 specimens collected, Lutzomyia longipalpis (54.87%) and Nyssomyia whitmani (30.41%) were the most abundant in the collection areas. Leishmania braziliensis DNA was detected in Lu. longipalpis, while L. braziliensis and Leishmania infantum DNAs were recovered from Ny. whitmani. Homo sapiens was the main blood meal source (~73%). Vector density was associated with humidity, temperature, and precipitation in Teresina and Pedro II, with significant results for Ny. whitmani. In conclusion, Lu. longipalpis, widely adapted to anthropized environments, can act as a potential vector of the etiological agent of cutaneous leishmaniasis in Teresina and Oeiras. In Pedro II, the detection of L. infantum DNA in Ny. whitmani suggests a possible role of this species in the transmission cycle of visceral leishmaniasis, reinforcing the complex ecoepidemiology of Leishmania spp. in Piauí.
