In Portugal human and canine leishmaniasis are caused by Leishmania infantum, and Phlebotomus perniciosus and P. ariasi are the proven vectors. Three main foci were identified in eighty's decade: Trás-os-Montes and Alto Douro region, Lisbon region and Algarve region, but according to OnLeish observatory data, canine leishmaniasis cases have been reported(More)
Visceral leishmaniosis caused by Leishmania infantum is a zoonotic disease in the Mediterranean basin. We report an epidemiological survey carried out in dogs from the municipality of Alijó in the endemic region of Alto Douro (north Portugal). Performance of the direct agglutination test (DAT) was assessed in 205 matching samples of blood collected on(More)
An intraspecific study on Phlebotomus sergenti, the main and only proven vector of Leishmania tropica among the members of the subgenus Paraphlebotomus was performed. The internal transcribed spacer 2 (ITS2) sequences of 12 populations from 10 countries (Cyprus, Egypt, Italy, Lebanon, Morocco, Pakistan, Portugal, Spain, Syria, and Turkey) were compared.(More)
In recent years there has been growing interest in analyzing the geographical variations between populations of different Phlebotomus spp. by comparing the sequences of various genes. However, little is known about the genetic structure of Phlebotomus ariasi. In this study, we were able to sequence a fragment of the mitochondrial Cyt b gene in 133 sandflies(More)
To the Editor: In southern Eu-rope, zoonotic visceral leishmaniasis caused by Leishmania infantum used to be considered a rural disease, but it is becoming more prevalent in urban areas. Outbreaks in urban/periur-ban settings are associated with the urbanization of natural zoonotic foci (1). The presence of a high number of stray dogs in urban/periurban(More)
This study reports isoenzyme polymorphism of Leishmania strains isolated in different regions of Portugal between 1982 and 2005. A total of 213 strains were obtained from cases of visceral and cutaneous leishmaniasis isolated from immunocompetent patients (adults and children) and immunocompromised adults, as well as from dogs and sandflies. Four zymodemes(More)
We reported the results of an entomological investigation in Marrakech area, in the aim to study the present Sergentomyia species composition. One hundred thirty seven sandflies were collected by sticky papers and they comprised three sub-genera: Parrotomyia (43.1%), Sergentomyia (36.5%), and Grassomyia (20.4%). Four species were identified; Sergentomyia(More)
Protozoal parasites are the causative agents of many insect-borne infectious diseases worldwide with impact on human and animal health. Leishmaniasis is caused by Leishmania spp. and transmitted by female Phlebotomine sand flies. In Portugal, two species of Phlebotomus (Larroussius), namely Phlebotomus perniciosus and Phlebotomus ariasi are the proven(More)
