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...

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...

We have developed a PCR assay for one-step differentiation of the three complexes of New World Leishmania (Leishmania braziliensis, Leishmania mexicana, and Leishmania donovani). This multiplex assay is targeted to the spliced leader RNA (mini-exon) gene repeats of these organisms and can detect all three complexes simultaneously, generating differently sized products for each complex. The assa...

Serum IgE levels and the expression of low affinity receptor for IgE (Fc epsilon RII/CD23) are increased in cutaneous leishmaniasis. The ligation of CD23 receptor by IgE-anti-IgE immune complexes results in nitric oxide (NO) production, which is a critical leishmanicidal factor. Human monocytes/macrophages express Fc epsilon RII/CD23 after activation with IFN-gamma and IL-4. In the present stud...

A 36 year old male was admitted in December 1997 to hospital with afternoon fever, malaise and hepatosplenomegaly. He also had a dry cough, dyspnoea and anaemia. Pneumonia caused by Pneumocystis carinii and human immunodeficiency virus (HIV) infection were documented. The HIV infection was confirmed in 1997 with 290,000 virus copies. The patient had been in the Mexican State of Chiapas which is...

This study investigated whether Leishmania species, the etiologic agent of cutaneous (Leishmania major) and visceral (Leishmania donovani) leishmaniasis, could differentially elicit early inflammatory events in vivo correlating with the subsequent development of their reciprocal pathogenesis. By use of the murine air pouch system, injection of Leishmania led to a rapid and transient accumulatio...

a 5-month old puppy with muco-cutaneous lesions in the chin, around lips and eyes was exam­ined physically and microscopically for leishmaniasis. muco-cutaneous lesions containing a large num­ber of amastigotes of leishmania spp. were observed . amastigotes were also detected in liver and spleen of the puppy. the animal was positive with dipstick rk39 kit and high level of anti- leishmania anti...
