Evaluation of the Loop-Mediated Isothermal Amplification (LAMP) Technique in Swab Samples from Ulcerated Cutaneous Lesions Compared with Conventional Diagnostic Methods for American Tegumentary Leishmaniasis in Patients Treated at a Reference Center in Rio de Janeiro, Brazil [PDF]

Tropical Medicine and Infectious Disease
Cutaneous leishmaniasis (CL) is a vector-borne disease caused by Leishmania spp. Molecular methods such as conventional PCR (cPCR) and real-time PCR (qPCR) show high accuracy but remain restricted to reference centers.

Susceptibility of Lutzomyia longipalpis (Lutz & Neiva, 1912) to Fludora FusionPM, a combination of clothianidin and deltamethrin: field and laboratory bioassays [PDF]

Parasites & Vectors
Background Insecticides remain a cornerstone in the control of vector-borne diseases. In Brazil, Alfatek 200SC—a pyrethroid (alphacypermethrin)—is recommended for controlling phlebotomine sand flies, the vectors of leishmaniases.
