Possibility of Leishmaniasis transmission in Jura, France

TO THE EDITOR: The report of a human cutaneous leishmaniasis case acquired in Clairvaux-les-lacs (1) led us to carry out an investigation with the veterinary clinics in Jura Department, France. Clairvaux-les-lacs is a lakeside resort located in Jura, one of the areas in France with the coldest average temperatures, and is clearly located outside the usual leishmaniasis-endemic area. At least 31 cases of canine leishmaniasis were diagnosed by veterinary clinics in Jura during 2007-2011. Because these dogs were native of or traveled in the leishmaniasis-endemic area along the Mediterranean Sea, all veterinarians considered the infections as acquired outside Jura

Distribution and ecological aspects of sand fly (Diptera: Psychodidae) species in Sri Lanka

WOS: 000287927300010PubMed ID: 21366784Human indigenous cutaneous leishmaniasis caused by Leishmania donovani complex is endemic in Sri Lanka. We performed an entomological survey to determine the distribution of probable vector species. Sand flies were collected in districts in the dry zone, in the wet zone highlands, and in the wet zone coastal belt of Sri Lanka using CDC light traps, sticky traps and cattle-baited net traps during July, 2005. The survey was reconducted in February, 2006. Overall, 584 sand flies belonging to Phlebotomus (266 specimens, 2 species) and Sergentomyia (318 specimens, 8 species) genera were collected. A total of 266 Phlebotomus was identified as P. argentipes (258/266; 97%) and P. stantoni (8/266; 3%) . The identification studies of Sergentomyia specimens showed that there are at least 8 species in Sri Lanka. Higher number of Phlebotomus sand flies (76/266) were caught in the southern part of the country compared to the other parts probably due to different ecological aspects. P. argentipes were widely distributed throughout the island whereas P. stantoni were collected only in four districts. Since P. argentipes is known to be the vector of L. donovani responsible of visceral leishmaniasis in India, this species may be incriminated as the most possible vector of human cutaneous leishmaniasis in Sri Lanka.Japan Society for the Promotion of ScienceMinistry of Education, Culture, Sports, Science and Technology, Japan (MEXT)Japan Society for the Promotion of Science [16406007, 19256001]This work was supported by Grant-in-Aid for Scientific Research (B) (16406007) and by Grant-in-Aid for Scientific Research (A) (19256001) from Japan Society for the Promotion of Science.

Molecular homogeneity in diverse geographical populations of Phlebotomus papatasi (Diptera, Psychodidae) inferred from ND4 mtDNA and ITS2 rDNA Epidemiological consequences

WOS: 000254602700008PubMed ID: 18243814An intraspecific study on Phlebotomus papatasi, the main proven vector of Leishmania major among the members of the subgerms Phlebotomus, was performed. The internal transcribed spacer 2 (ITS 2) of rDNA and the ND4 gene of mt DNA were sequenced from 26 populations from 18 countries (Albania, Algeria, Cyprus, Egypt, Greece, India, Iran, Israel, Italy, Lebanon, Morocco, Saudi Arabia, Spain, Syria, Tunisia, Turkey, Yugoslavia and Yemen), and compared. Samples also included three other species belonging to the subgenus Phlebotomus: P. duboscqi, a proven vector of L major in the south of Sahara (three populations from Burkina Faso, Kenya and Senegal), P. bergeroti, a suspected vector of L. major (three populations from Oman Sultanate, Iran and Egypt), and one population of P. salehi from Iran. A phylogenetic study was carried out on the subgenus Phlebotomus. Our results confirm the validity of the morphologically characterized taxa. The position of P. salehi is doubtful. Variability in P. papatasi contrasts with that observed within other species having a wide distribution like P. (Paraphlebotomus) sergenti in the Old World or Lutzomyia (Lutzomyia) longipalpis in the New World. Consequently, it could be hypothesized that all populations of P. papatasi over its distribution area have similar vectorial capacities. The limits of the distribution area of L major are correlated with the distribution of common rodents acting as hosts of the parasites. (C) 2007 Elsevier B.V. All rights reserved
