“…P. longicuspis was the second most predominant species (14%) identified in this area, yet this species is mainly found in the semi-arid and the arid bioclimatic zones. During a study conducted in August 1989 in a village (Taourit-Aden, altitude 500 m) located in the vicinity of LNI area, P. perfiliewi, the second predominant species, was found (Izri et al 1990). In our study, P. perfiliewi was poorly represented (<1%).…”

“…In Algeria, the confirmed vectors are P. perniciosus for L. infantum MON-1 and P. perfiliewi for L. infantum MON-24 (Izri et al 1990;1993). Parrot et al (1941) proposed for the first time P. longicuspis as potential vector of visceral leishmaniasis (VL) parasite, but so far, no confirmatory data have been published.…”

“…Hence, 485 cases including HVL and SCL were documented and recorded from 2004 to 2005 (Achour and Madiou 2009). Sandflies belonging to the subgenus Larroussius (Phlebotomus perniciosus and Phlebotomus perfiliewi) are so far the confirmed vectors in northern Algeria (Izri et al 1990;1993). The isoenzymatic analysis of L. infantum strains isolated within humans, vertebrate host reservoirs, and sandfly vectors revealed the presence of six zymodemes: MON-1, MON-24, MON-33, MON-34, MON-78, and MON-80 (Benikhlef et al 2004;Harrat et al 1996).…”

First detection of Leishmania infantum DNA in Phlebotomus longicuspis Nitzulescu, 1930 from visceral leishmaniasis endemic focus in Algeria

Two clinico-epidemiological forms of leishmaniasis caused by Leishmania infantum complex are endemic in Algeria: human visceral leishmaniasis (HVL) and sporadic cutaneous leishmaniasis. In the northern part of the country, the Kabylian region is the main endemic HVL focus with more than 200 cases recorded annually. During the summer of 2009, an entomological study was performed in Larbaa Nath Irathen with the aim to identify the vectors of Leishmania and of phleboviruses. In the present paper, we report the results of the Leishmania vectors. In the field, female sand flies, which were alive at collection time, were morphologically identified and examined for the presence of promastigotes. The remaining sandflies (males and dead females) were carried to the laboratory for morphological identification and molecular analysis. Total DNA was extracted from each female sandfly, and ITS2 Leishmania was amplified by PCR. A total of 883 sandfly specimens were collected. Ten distinct species were morphologically identified: one species belonged to the Sergentomyia genus and nine to the Phlebotomus genus. L. infantum DNA was amplified in 1/169 (0.6%) dissected dead females, one Phlebotomus longicuspis. Our data support the Parrot's hypothesis raised in 1941 concerning the role of P. longicuspis in the transmission of L. infantum.

“…P. (L.) perniciosus has got the largest distribution (D = 84 %) (Tables Ia and Ib). It was the most abundant Larroussius species in most studied VL sites (Ghezala, Aïn Jloula and Sidi Salem) and probably represents the main vector of VL in northern and central Tunisia as reported in other Mediterranean countries (Table IIa and IIb) (AlvesPires, 1984;Bettini et al, 1986;Rioux et al, 1986b;Maroli et al, 1988;Izri et al, 1990;Izri et al, 1992). However, in Marthouma, the dominance of P. perniciosus in CDC traps and P. perfiliewi in sticky traps suggests that more than one species could be incriminated in the transmission (Table IIa and IIb) (Dancesco et al, 1970;Alves-Pires, 1984;Rioux et al, 1986b;Izri et al, 1992).…”

Phlebotominae (Diptera: Psychodidae) of human leishmaniosis sites in Tunisia

Summary :In order to identify the phlebotomine sandfly populations in Tunisian leishmaniosis foci, an entomological survey was carried out through three entomological seasons (2002-2003-2004) in 19 visceral and cutaneous leishmaniosis areas, located in six bioclimatic zones. Sandfly collections were based on light and sticky traps placed around human leishmaniosis cases. 8,722 phlebotomine sandflies belonging to 12 species were collected. The dominance of subgenus Larroussius species in northern foci, Phlebotomus papatasi in south-western foci and their co-dominance in the centre of the country is in accordance with the distribution of Leishmania infantum and L. major in Tunisia. The low density found in the historical zoonotic cutaneous leishmaniosis focus of Metlaoui in the south-west may indicate the high competence of the local populations. Studied phlebotomine settlements have showed a low specific diversity in most of the studied sites. In L. infantum areas, the dominant species were respectively: P. perfiliewi in the cutaneous leishmaniosis site of the humid bioclimatic stage, P. perniciosus in the cutaneous and visceral leishmaniosis foci of semi-arid and arid bioclimatic stages and P. longicuspis in the visceral leishmaniosis focus of saharan bioclimate. In the zoonotic cutaneous leishmaniosis foci, P. papatasi was a dominant species. In the well-known southeastern foci of cutaneous leishmaniosis due to L. killicki, P. sergenti was a dominant species with P. perniciosus. In the central emerging foci of L. killicki, P. perniciosus was a dominant species in some sites whereas it was very rare in others. In these sites, the subgenus Paraphlebotomus was always present with a higher abundance of P. alexandri than P. sergenti. Résumé

“…Indeed, P. ariasi (Rioux et al 1984a) and P. (L.) perniciosus Newstead 1911 (Izri et al 1990) were demonstrated as vectors of visceral and cutaneous leishmaniases due to Leishmania infantum, both from Portugal to Italy and from Morocco to Tunisia, where Canidae are reservoir hosts. L. infantum may be also present in the semi-arid belt in sympatric condition with L. tropica , and even in the arid belt (Dereure et al 1986).…”
