detection and identification of leishmania parasites within sand flies using kdna, rdna and cpb loci
objective: molecular epidemiology of visceral leishmaniasis (vl) is currently used widely for different objectives such as vector incrimination studies. materials and methods: in this study three different loci including kinetoplast dna (kdna), ribosomal dna (rdna), and cystein protease b (cpb) of leishmania parasite genome were used for detection and identification of natural infection of san...
ایمپلنت h.a چشمی در ابتدا بوسیله آرتورپری در 1985 بکار رفته برای استفاده عمومی در 1989 بوسیله fda، توسعه یافت . ما در یک مطالعه مقطعی، عوارض ایجاد شده در بیمارانی را که بعد از تخلیه چشم در آنها کره هیدروکسی آپاتیت کار گذاشته شده بود، بررسی کردیم. این مطالعه بر روی بیماران از سال 1372 تا 1377 انجام شده است . از بین 30 مورد بیمار مورد مطالعه، 8 مورد (26 درصد) دچار عارضه شده بودند که 6 نفر آنها مر...

Introduction: Cutaneous Leishmaniasis cases have recently increased in Bastak area in Hormozgan province. There is no practical information on the causes and vectors of this disease in the region. This study was designated in order to focus on various aspects of the vectors in Bactak area. Methods: In this descriptive study, sand flies were collected biweekly from human dwellings and rodent b...

We report experimental infection and transmission of Leishmania tropica (Wright), by the blood-feeding sand fly Phlebotomus duboscqi (Neveu-Lemaire). Groups of laboratory-reared female sand flies that fed "naturally" on L. tropica-infected hamsters, or artificially, via membrane feeding device, on a suspension of L. tropica amastigotes, were dissected at progressive time points post-feeding. Ac...
Leishmania ISPs are ecotin-like natural peptide inhibitors of trypsin-family serine peptidases, enzymes that are absent from the Leishmania genome. This led to the proposal that ISPs inhibit host serine peptidases and we have recently shown that ISP2 inhibits neutrophil elastase, thereby enhancing parasite survival in murine macrophages. In this study we show that ISP1 has less serine peptidase...
one hundred sixty two domestic fowls were examined for toxoplasma infection by both indirect haemagglutination tests for toxoplasma antibodies and inoculation of their brains intraperitoneally into mice for the parasite. the overall sero-positive rate (spr) was 29 percent with the titers ranging from 1:20 to 1:6400. the number of each species tested and their spr were: 74 hens (27.0%), 35 roost...
