UNLABELLED Leishmaniasis has been documented in several countries, with an estimated prevalence of 12 million people and an incidence at around 400,000 new cases per year. Leishmaniasis in the New World is one the major endemic diseases in Brazil and Latin America. OBJECTIVE The aim of this study was to add to the current knowledge on mucosal leishmaniasis, bringing the experience of the Immu...

IgG avidity tests are used to discriminate acute from chronic infections. There are few reports on the IgG avidity profile of patients with visceral leishmaniasis (VL). This study investigated the anti-Leishmania IgG avidity in patients with classic VL (n = 10), patients showing clinical cure after treatment (n = 18), and asymptomatic subjects with at least one positive Leishmania test (n = 20)...

Experimental animal models have been used for the study of the physiopathogenesis of leishmaniasis, on some occasions with success, while in other situations such as bone alterations that accompany tegumentary leishmaniasis, especially in diffuse cutaneous form (DCL), the mechanisms are still unknown. In the present study, we determined these alterations in an animal model susceptible to Leishm...

BACKGROUND Concomitant infections may influence HIV progression by causing chronic activation leading to decline in T-cell function. In the Americas, visceral (AVL) and tegumentary leishmaniasis (ATL) have emerged as important opportunistic infections in HIV-AIDS patients and both of those diseases have been implicated as potentially important co-factors in disease progression. We investigated ...

INTRODUCTION Leishmaniasis is a neglected tropical disease caused by vector-borne protozoa of the genus Leishmania. Cutaneous and mucocutaneous forms result in disfiguration or mutilation, whilst visceral leishmaniasis (VL) affects multiple organs and is fatal if untreated. Notably, Leishmania are capable of establishing a chronic infection, which may reactivate years after initial infection wh...

Both cutaneous and visceral forms of leishmaniasis are prevalent in some parts of the Islamic Republic of Iran [1,2]. The Mediterranean type of visceral leishmaniasis (VL) is also reported sporadically throughout the country [3] with canines being the main animal reservoir hosts [4]. The cutaneous form of leishmaniasis is seen in 2 forms: anthroponotic and zoonotic. Anthroponotic cutaneous leis...

Leishmaniasis has a long history in the Islamic Republic of Iran. This study aimed to show the trend in leishmaniasis incidence from 1983 to 2012 and to describe the epidemiological characteristics in 2012. In a retrospective cross-sectional study, data were extracted from th%e national leishmaniasis surveillance system for the 3 clinical types-cutaneous (zoonotic and anthroponotic) and viscera...

Leishmaniasis is a family of infectious diseases caused by parasites of the genus Leishmania and transmitted through the bite of sandflies. The geographical distribution of Leishmaniasis is tied in to the abundance of sandflies, their life cycle, and the presence of the parasite reservoirs. The World Health Organization classifies Leishmaniasis as a neglected disease affecting the poorest commu...

Cutaneous leishmaniasis is the most common form of leishmaniasis caused by flagellate protozoa of the genus Leishmania transmitted by sand fly bites. Old World leishmaniasis is endemic in the Mediterranean Sea and the neighbouring countries. We present a case of a 10-year-old boy with a cutaneous leishmaniasis in form of papules on the nose, right and left lower leg. Histopathological examinati...

L eishmania is an early-branching unicellular eukaryote belonging to the order Kinetoplastidae and family Trypanosomatidae. At least 20 Leishmania spp. cause leishmaniasis, vector-borne parasitic diseases with a large spectrum of clinical symptoms that depend on the species. Leishmania infects mononuclear phagocytes, key cellular components of the immune system. Intracellular survival of these ...
