Leishmania infantum is the obligatory intracellular parasite of mammalian macrophages and causes zoonotic visceral leishmaniasis (ZVL). The presence of infected dogs as the main reservoir host of ZVL is regarded as the most important potential risk for human infection. Thus the prevention of canine visceral leishmaniasis (CVL) is essential to stop the current increase of the Mediterranean visce...

BACKGROUND In this paper we study the distribution of leukocyte populations and of cytokine-producing cells in the spleen of a patient with visceral leishmaniasis resistant to clinical treatment. It is the first attempt to compare the distribution of leukocyte populations and cytokine-producing cells in the splenic compartments of a patient with visceral leishmaniasis with those observed in pat...

conclusions: according to our results, it is likely that the increased frequency of the fcγriiib-na1/na2 genotype is associated with impaired immune responses against vl and its subsequent clearance from the patient. results: our results indicated that polymorphisms within the fcγriiib gene (that lead to the expression of the na1/na2 isoforms) are significantly associated with vl. the results d...

background: visceral leishmaniasis (vl) is an endemic disease in some parts of iran. many techniques have been used for diagnosis of vl, among which the urine based la-tex agglutination test (katex) is a promising one. objective: to compare three diag-nostic tests of vl including katex, elisa and direct agglutination test (dat) in vl patients and healthy controls in the south west of iran. meth...

leishmania infantum is the most frequent cause of visceral leishmaniasis and l. tropica has been rarely linked to the disease in iran. in this study, bone marrow aspirates were collected from 10 child patients, suspected with visceral leishmaniasis referred to the pediatric wards of kerman medical hospitals, kerman, iran during 2002–2011. leishmania species were identified by using nested pcr i...

Forty-one naturally infected dogs with visceral leishmaniasis from an urban area of Corumbá (Mato Grosso do Sul-BRAZIL) were studied and three types of lung involvement due to visceral leishmaniasis were characterized; a cellular, a cellular-fibrotic and a fibrotic type. These types seem to represent a sequential evolutive proce'as. Visceral leishmaniasis frequently causes an interstitial pneu ...

Leishmaniasis is a neglected tropical disease infecting world’s poorest population in over 90 countries throughout Asia, Africa, the Middle East, and Central South Africa. An underestimated 700,000 to one million new cases occur annually. refers spectrum of diseases caused by parasite, Leishmania, transmitted bite infected sandflies. Of three major syndromes (cutaneous, mucosal visceral) leishm...

visceral leishmaniasis (vl) is a zoonotic disease caused by leishmania species. dogs are considered to be the main reservoir of vl. a number of methods and antigen-based assays are used for the diagnosis of leishmaniasis. however, currently available methods are mainly based on direct examination of tissues for the presence of parasites, which is highly invasive. a variety of serological tests ...

background: previous studies revealed that selectins play key roles in homing of immune cells to inflamed tissues and lymphatic organs. l-selectins are expressed on immune cells and interact with p and e selectins to homing to the tissues, hence, the polymorphisms within the gene of l-selectins may are associated with alteration in its expression. thus, the current cross-sectional analytical st...

background: visceral leishmaniasis (vl) as one of the most important human parasitic disease is endemic in some parts of iran. several cases of vl have been reported recently in the ilam province. the current study aimed to assess the pre-sent status of human vl in the region. methods: a random cluster sampling method was used to collect 456 serums samples from the children up to 12 years of ag...
