We studied the reservoir competency of canines with distinct clinical presentations of Leishmania chagasi infection. The parasitologic status of asymptomatic and symptomatic dogs was determined by standard culture methods Infectivity was assessed by multiple xenodiagnoses with Lutzomyia longipalpis, over a period of 2-11 months. Asymptomatic dogs were non-infective (0 of 5) while 2 of 7 oligosy...

b a ckground: sand flies of subgenus adlerius has a wide geographical distribution in iran and are mostly found in wild form in mountainous areas. they are always considered as probable vectors of visceral leishmaniasis. the ob- jective of this study was to determine the adlerius species and its composition in an endemic focus of zoonotic vis- ceral leishmaniasis in northwest of the country. m ...

the sefidrud dam was constructed and made operational in iran in 1962. the reservoir lost a considerable amount of its storage capacity in the first two decades of its operation when about 800 mcm sediment deposited in it and by considering the total capacity, 1800 mcm, the live storage capacity was reduced by 45 percent in 1980. the gilan project authorities have attempted to recreate the rese...

This study focused on the determination of detailed grain morphology using SEM technology on some Athabasca oil sands samples obtained from the Upper McMurray Formation in the Manville Group which occurs in the Western Canada Sedimentary Basin. The research was carried out using scientific techniques to understand grain morphology—being a major effect in discerning reservoir quality—a factor wh...

BACKGROUND Zoonotic cutaneous leishmaniasis has long been endemic in Israel. In recent years reported incidence of cutaneous leishmaniasis increased and endemic transmission is being observed in a growing number of communities in regions previously considered free of the disease. Here we report the results of an intensive sand fly study carried out in a new endemic focus of Leishmania major. Th...

Reports from the health center of Kerman Province, southern Iran showed an increasing of cutaneous leishmaniasis cases in Orzuieh Rural District, southwest of the province in 2003. The report encouraged the team to carry out an epidemiological survey in the district during 2003-2004. The objectives were to determine the ecology of sand flies, potential reservoir hosts and human infection. A tot...
