Infection of sand flies collected from different bio-geographical areas of Tunisia with phleboviruses.

Abstract : An entomological investigation performed in 2013 covering different bio-geographical areas varying from humid in the north to the arid in the center showed that sand flies of the subgenus Larroussius including Phlebotomus perniciosus, Phlebotomus perfiliewi, and Phlebotomus longicuspis are abundant and widely distributed in Tunisia A total of 3992 collected and pooled with up to 30 specimens per pool based on sex, trapping location and collection date were tested for the presence of phleboviruses by nested reverse transcriptase polymerase chain reaction and sequencing Of a total of 135 pools, 23 were positive, yielding and minimum infection rate of 0.6%. Phylogenetic analysis performed using partial amino acid sequence in the polymerase gene showed that all these phleboviruses were grouped in one cluster clearly distinct from but closely related to Massilia virus and Granada virus This putative novel virus, tentatively called Saddaguia virus (SADV), is widely distributed in Tunisia Together with Toscana, Punique, and Utique viruses, SADV is the fourth recognized phlebovirus to be transmitted by sand flies in Tunisia The medical and public health interest of SADV remains to be investigated.
