are PCR positive and/or leishmanial antibody positive become infected with L. infantum. Persons with advanced AIDS or other immunosuppressive conditions seemingly would be at greatest risk for VL. In Brazil, legislation requires that all blood for transfusion be tested for T. cruzi ., hepatitis B and C, T. pallidum, human T-cell lymphotropic virus types 1 and 2, and HIV1 and -2. As additional i...
The cotton boll weevil (Anthonomus grandis) causes severe cotton crop losses in North and South America. This report describes the presence of cysteine proteinase activity in the cotton boll weevil. Cysteine proteinase inhibitors from different sources were assayed against total A. grandis proteinases but, unexpectedly, no inhibitor tested was particularly effective. In order to screen for acti...
The implantation of the mouse embryo requires the controlled invasion of the uterine stroma by the embryonic trophoblast. This event is dependent, in part, on the secretion of matrix metalloproteinases and serine proteinases for the extracellular degradation of the uterine matrix. Proteinase activity is controlled by stromal decidualization and specific proteinase inhibitors. This work adds to ...
In order to investigate whether pigs can be infected by Leishmania infantum, a serological and parasitological study was carried out on swine in the Jequié municipality, Northeast of Brazil. Anti-Leishmania infantum antibodies were detected in 37 out of 92 swine (40.2%), by two different assays: an anti-L. infantum lysate and an anti-K39 recombinant protein ELISA. An experimental study was also...
background: visceral leishmaniasis is caused by leishmania infantum , transmitted to humans by bites of phlebotomine sand flies and is one of the most important public health problems in iran. to identify the vector(s), an investigation was carried out in bilesavar district, one of the important foci of the disease in ardebil province in northwestern iran, during july - september 2008 . meth...
To determine the role that Leishmania infantum/human immunodeficiency virus (HIV) coinfected patients could play in the epidemiology of visceral leishmaniasis (VL), we applied direct xenodiagnosis of VL in this study to test the infectivity of six coinfected patients to colonized Phlebotomus perniciosus. All patients proved to be infective for the sand flies. The infectivity of patients who had...
