Presence of sandflies infected with Leishmania infantum and Massilia virus in the Marseille urban area

Abstract

Leishmaniasis is considered a rural disease in Europe. However, circumstantial evidence has indicated urban transmission of leishmaniasis and phleboviruses in the urban area of Marseille, France. To investigate this urban transmission, sandflies were trapped in 33 locations in the urban area (horse farms, public gardens and a residential area). Sandflies were always captured: 87.8% were Phlebotomus perniciosus, a vector of Leishmania infantum and Toscana and Massilia viruses. RT-PCR and cell culture inoculation identified the Massilia virus in 2/99 pools of sandflies, and PCR identified Leishmania in 5/99. No dual infection was observed, but both pathogens were detected in samples from the same trapping site. © 2013 European Society of Clinical Microbiology and Infectious Diseases.
