Abstract
ABSTRACT: Leishmaniasis is a zoonotic disease caused by parasites of the Leishmania genus, resulting in various clinical forms, including a highly lethal visceral form. This study aimed to identify Leishmania spp. in sandflies and dogs in a small Brazilian town. DPP® Visceral Canine Leishmaniasis (CVL) was used for screening, and ELISA and conventional PCR were used for confirmatory testing, while sandflies were captured using CDC light traps and conventional PCR targeting ITS1. The Hill series was used to identify the diversity profile of species in the sampled area using R software. The study identified a Leishmania spp. prevalence of 4.02% in dogs, exceeding the 2% limit required by the Brazilian Ministry of Health. A total of 443 sandflies belonging to 14 different species were identified, with Lutzomyia longipalpis being the most abundant (73.81%). Negligence regarding leishmaniasis in small towns can lead to late diagnosis, hence the need to implement effective strategies, including early diagnosis and treatment of human and canine cases, vector control programs, and awareness campaigns to educate the public about risks and preventive measures. These measures can help prevent the spread of leishmaniasis and improve health outcomes for affected individuals and animals.
