Mapping the global distribution of Strongyloides stercoralis and hookworms by ecological niche modeling.

Background: The WHO has established a control strategy for Strongyloides stercoralis in school-aged children as well as targets and to maintain control programs for Ascaris lumbricoides, Trichuris trichiura and hookworms. For an efficient development of control programs, it is necessary to know the target countries around the world, as well as the areas within each country where efforts should be focused. Therefore, maps that provide information on the areas at risk for soil-transmitted helminth (STH) infections on a national and sub-national scale would allow for a better allocation of resources.

Molecular Identification of spp. DNA from Archived Giemsa-Stained Slides of Patients from Salta, Argentina.

Cutaneous leishmaniasis is endemic in Salta province, which belongs to the northwest of Argentina. spp. DNA from Giemsa-stained slides of up to 12 years in storage of patients from Salta was characterized through polymerase chain reaction (PCR) restriction fragment length polymorphism (RFLP).

Reappraisal of Leishmanin Skin Test (LST) in the management of American Cutaneous Leishmaniasis: A retrospective analysis from a reference center in Argentina.

Leishmania (Viannia) braziliensis is the species most frequently implicated with cutaneous and mucosal leishmaniasis in the Americas; its diagnosis is based on the identification of amastigotes in lesions, which is limited by low parasite burden. Leishmanin Skin Test (LST) is a support tool for diagnosis, based on delayed type hypersensitivity responses to Leishmania antigens injected intradermally, used in endemic areas as a complement to diagnosis. A retrospective analysis of individuals evaluated for their first episode of tegumentary leishmaniasis at a reference center in Argentina during the period 2006-2015 was performed, with the goal of assessing its usefulness as a support tool in the diagnosis of leishmaniasis.
