Following an epidemiological survey of zoonotic cutaneous leishmaniosis (ZCL) in some villages of Badrood, a rural district north of the city of Natanz, central Iran, Phlebotomus (Phlebotomus ) papatasi Scopoli were found to be naturally infected with Leishmania (Leishmania) major zymodeme MON-26. Sandflies were collected and dissected biweekly from rodent burrows during sandfly season, Ap...

Transmission of leishmaniasis is effected by a specific developmental stage, the metacyclic promastigote. The precursors of metacyclic promastigotes were a distinct subpopulation of parasites, identified for the first time as a new stage in the life-cycle and named leptomonad promastigotes. Microdissection of infected sandflies into 4 midgut regions and foregut allowed precursor-product relatio...

Following an epidemiological survey of zoonotic cutaneous leishmaniasis (ZCL) in several villages of Badrood, a rural district north of the city of Natanz, central Iran, Phlebotomus (Phlebotomus) papatasi Scopoli were found to be naturally infected with Leishmania (Leishmania) major zymodeme MON-26. Sand flies were collected and dissected biweekly from rodent burrows from May to October 2001. L...

background phlebotomus papatasi and p. salehi are reported as vectors of cutaneous leishmaniasis in southeast of iran. seasonal activity of these species is different in zoogeographical zones and must be known well for better management of the disease. objectives to determine the nocturnal activity of sand flies and their leptomonad infection rates. materials and methods a cross-sectional study...

objective: an entomological survey was carried out for leishmania vector incrimination of sand flies in northwestern iran. materials and methods: among other specimens, 358 sand flies belong to the sergentomyia genus were tested for leptomonad infection using semi-nested pcr method as well as sequence anlalysis of its-rdna fragment. results: results of semi-nested pcr against kietoplast dna...

zoonotic cutaneous leishmaniosis is endemic in chabahar area, south east of iran. in order to determine the natural leptomonad infection of phlebotomine sandflies caught from rodent burrows, an investigation was carried out in three foci of this area during june to october 1997. sandflies were collected by sticky traps, placed at the openings of meriones hurrianae and tatera indica burrows. tot...

BACKGROUND The binding of Leishmania promastigotes to the midgut epithelium is regarded as an essential part of the life-cycle in the sand fly vector, enabling the parasites to persist beyond the initial blood meal phase and establish the infection. However, the precise nature of the promastigote stage(s) that mediate binding is not fully understood. METHODOLOGY/PRINCIPAL FINDINGS To address ...

In a former communication one of us (Row, 1922) had pointed out that the flagellate leptomonad forms of Leishmania tropica reverted to the leishmania O-bodies and these made their appearance in the condensation fluid of NNN culture tubes inoculated with the parasite 2 to 3 weeks previously. These were described as the O-bodies, or resistant forms, and it is the presence of these in old cultures...
