Chagas disease and the leishmaniases are endemic zoonoses of great importance to public health in the state of Piauí, Brazil. The domestic dog (Canis familiaris) is a major reservoir, host of Trypanosoma cruzi and Leishmania spp. in both urban and rural areas, playing an important role in the transmission of these parasites. The present study evaluated the prevalence of both infectious diseases...
The leishmaniases are neglected tropical diseases of significant public health importance. However, information on their global occurrence is disparate and sparse. This database represents an attempt to collate reported leishmaniasis occurrences from 1960 to 2012. Methodology for the collection of data from the literature, abstraction of case locations and data processing procedures are describ...
Leishmaniases are worldwide diseases transmitted to the vertebrate host by the bite of an infected sand-fly. Sand-fly biting and parasite inoculation are accompanied by the injection of salivary molecules, whose immunomodulatory properties are actively being studied. This mini review focuses on how the interactions between sand-fly saliva and the immune system may shape the outcome of infection...
Leishmania are protozoan parasites that cause several human diseases called leishmaniases, which can display very different clinical aspects (Peters and Killick-Kendrick, 1987b). The life cycle of Leishmania involves two kinds of hosts: dipteran insects (sandflies) and several mammals, in which they adopt a motile, flagellated, promastigote form and a non-motile, amastigote form with a very sho...
Phlebotominae includes some vector species, mainly that of leishmaniases, with a very old host-parasite relationship. Some species fossils of this subfamily have been recently described and this paper presents the description of a new sand fly Pintomyia (Pifanomyia) paleotownsendi sp. nov in amber. The gonostyle present four spines, being one apical, one external superior implanted close to the...

Visceral and cutaneous leishmaniases are endemic in some parts of Kenya, where they are transmitted by phlebobotomine sandflies of genus Phlebotomus. This review is a compilation of the currently known distribution of phlebotomine sandflies in the parts of Kenya that have been studied, from the time sandflies were first reported in the country. So far 48 species of sandflies have been identifi...
