To editor: Toscana Virus belongs to the genus Phleobovirus, family Bunyaviridae. They are transmitted in the Mediterranean area by Phlebotomus perniciosus and Phlebotomus perfiliewi sandflies (Braito et al., 1997). Toscana virus (TOSV) was first isolated in 1971 from Phlebotomus perniciosus in Monte Argentario (Grosseto, Tuscany) (Verani et al., 1982). Sandflyborne TOSV was recognized as a lead...

Geographical information systems and remote sensing were used to analyze the distribution of the Leishmania infantum-Phlebotomus perniciosus parasite-vector system in relation to environmental features of two opposite sides (coastal and Apennine) of Mt. Vesuvius, an area of intense transmission of human and canine leishmaniasis in southern Italy. Weekly phlebotomine collections were carried out...

Leishmania donovani chagasi parasites, transmitted by sandflies of the Lutzomyia longipalpis species complex, normally cause visceral leishmaniasis. However, in Central America infections frequently result in cutaneous disease. We undertook experiments to investigate the possible influence of sandfly saliva on the course of infection. Erythemas caused by feeding sandflies correlated well with t...

The bloodsucking adult females of Phlebotomus perniciosus Newstead and P. longicuspis Nitzulescu (Diptera: Psychodidae) are important vectors of the protozoan Leishmania infantum Nicolle (Kinetoplastida: Trypanosomatidae) in western Mediterranean countries. The species status of the two phlebotomine sandflies was assessed, along with the epidemiological implications. Individual sandflies from t...

Sandfly prevalence in the Kani tribe settlements of Western Ghats in India was investigated. A total of 1,279 sandflies comprising 17 species was obtained. Sandfly abundance showed a negative correlation (r = -0.97, p = 0.003) with increase in altitudinal ranges from 0-1,000 m. When sandfly samples were grouped according to landscape characteristics of the location, the estimated Shannon-Weiner...

Leishmania parasites must survive and proliferate in two vastly different environments - the guts of poikilothermic sandflies and the antigen-presenting cells of homeothermic mammals. The change of temperature during the transmission from sandflies to mammals is both a key trigger for the progression of their life cycle and for elevated synthesis of heat shock proteins, which have been implicat...

INTRODUCTION American cutaneous leishmaniasis (ACL) has been reported in every municipality of the State of Mato Grosso, Brazil, but the transmission epidemiology remains poorly understood. Our study was developed in a rural area of the Nova Mutum municipality where four autochthonous cases of ACL were reported in 2009. Our aims were to describe the local phlebotomine sandfly fauna and to inves...

In this study, we used Random Amplified Polymorphic DNA (RAPD) for identification of 17 isolates of Leishmania from the skin and reticuloendothelial system of humans, animal reservoirs (rodent and dog) and sandflies in various parts of Iran in the last decade. Fifteen species have been confirmed by isoenzyme characterization by the London School of Hygiene and Tropical Medicine and Shiraz ...

According to the WHO, infectious diseases, and in particular neglected tropical diseases in poor developing countries, still play a significant role in a vast number of deaths reported worldwide. Among them, leishmaniasis occurs as a complex and clinically diverse illness caused by protozoan Leishmania species which are transmitted through the bite of sandflies. They develop through a complex l...

Protozoan parasites [1]: 1) Leishmania major; 2) L. tropica; 3) L. infantum (very rare) WHO case definition Suspected case A person showing clinical signs (skin lesions). A papule appears, which may enlarge to become an indolent ulcerated nodule or plaque. The sore remains in this stage for a variable time before self healing and typically leaves a depressed scar. Other atypical forms may occur...
