Leishmaniasis is common in western and southern portions of Venezuela, where it tends to occur in hot, humid regions below 600 meters. This article describes the results of a survey pe$ormed during 1978-1979 in westem Venzzuela above 600 meters, where teishmaniasis caused by a recentb iaknt$ed parusitz (Leishmania gamhami) is common, but where the mucosal lesions often associated with the disea...

Cutaneous leishmaniasis is an infectious disease that is caused by protozoa belonging to the genus Leishmania and typically manifests with a single lesion on sun exposed areas. It is frequent in the Mediterranean Basin where it is most commonly due to Leishmania Infantum. In the literature, there is a number of reports describing atypical presentations, including that manifesting with multiple ...

Whether cutaneous leishmaniasis exists in China is a problem of concern in the international field of parasitology. Zhang and Hu (1983) found a girl aged 15 with mild hepatomegaly and cutaneous ulcer on her right cheek in Shawan County of Xinj­ iang; Leishmania was detected in both the exudates and biopsy tissues, but the parasite was not detected in a bone marrow smear. Notwithstanding the fac...

An important NK-cell inhibition with reduced TNF-α, IFN-γ and TLR2 expression had previously been identified in patients with diffuse cutaneous leishmaniasis (DCL) infected with Leishmania mexicana. In an attempt to pinpoint alterations in the signaling pathways responsible for the NK-cell dysfunction in patients with DCL, this study aimed at identifying differences in the NK-cell response towa...

A case of HIV/Leishmania co-infection presenting both visceral and cutaneous manifestations is reported. Leishmania infection was confirmed by conventional methods (parasitological approach and serology) and by PCR. Leishmania chagasi isolated from the skin lesion was characterized by enzyme electrophoresis and by restriction fragment length polymorphism of the internal transcribed spacer of th...

Cutaneous leishmaniasis (CL) is a public health problem on a global level because it affects the population of 88 countries. In Morocco, it is widely distributed, caused by Leishmania tropica, Leishmania major and Leishmania infantum rarely. The geographical distribution of different forms of leishmaniasis in Morocco is linked to well described bioclimatic zones. Over the past two decades, the ...

backgrounds and aims: the protozoan parasites of the genus leishmania can be stated as the causative agents of the various clinical diseases. fetal calf serum (fcs) is the major part of the leishmania culture media, which is the most expensive ingredient in these media. the coconut water is packed with nutrients that yield an array of health benefits. materials and methods: in the present study...

Basal cell carcinoma (BCC) is the most common malignant tumor of the skin, which originates from the basal cell layer of the skin. It is more common in white race with skin types I and II. Some predisposing factors are sunlight, ionizing radiation, arsenic salts, PUVA and scar. We present a case of BCC, which appeared over an old scar of localized cutaneous leishmaniasis in a 49-year-old woman.

three species of l. tropica, l. major and l. infantum are known as main causal agents of leishmaniasis have been reported in iran. since cutaneous leishmaniasis (cl) is endemic in north east of iran, in the present work, 50 leishmania positive isolates from human cases in mashhad (center of razavi province, north east of iran), were genotyped by means of polymerase chain reaction-restriction fr...

Leishmaniases are endemic zoonoses in the State of Mato Grosso do Sul. Their etiological agents in this region of Brazil are Leishmania (Leishmania) chagasi, Leishmania (Leishmania) amazonensis and Leishmania (Viannia) braziliensis. The polymerase chain reaction (PCR) is a tool with high specificity and sensitivity for identifying Leishmania species. This study examined 39 cryopreserved isolate...
