Twenty cutaneous leishmaniasis (CL) cases were notified from December 2001 to February 2002, in a small village in the district of Oueslatia (governorate of Kairouan, central Tunisia) which is an endemic focus of infantile visceral leishmaniasis due to leishmania (L.) infantum and that had never been concerned previously by CL. The parasite typing of two isolates obtained from two children that...

In Brazil, American visceral leishmaniasis (AVL) is caused by Leishmania (Leishmania) chagasi and its main vector is Lutzomyia longipalpis. Cases of canine visceral leishmaniasis (CVL) in non-endemic areas have been reported over the last few years throughout the country. The objective of this research note is to describe an autochthonous case of CVL that occurred in the municipality of Volta R...

toxicity and drug resistance against pentavalent antimonials, medications of choice in treatment of leishmaniasis for more than 5 decades, have become important subjects globally. this study was a randomized, open labeled trial that was designed to determine efficacy and safety of imod as a novel herbal immunomodulator drug for treatment of canine visceral leishmaniasis (cvl).twenty healthy mon...

BACKGROUND Co-infection of leishmaniasis and HIV is increasingly reported. The clinical presentation of leishmaniasis is determined by the host immune response to the parasite; as a consequence, this presentation will be influenced by HIV-induced immunosuppression. As leishmaniasis commonly affects the skin, increasing immunosuppression changes the clinical presentation, such as in post-kala-az...

To evaluate whether familial clustering occurs in mucosal leishmaniasis (ML), patients with ML (index cases) were randomly selected from medical records at a health post in an endemic area for Leishmania braziliensis infection. Control individuals (index controls) matched by age, gender, and place of residence to index cases were selected. Family members of index cases and controls were compare...

Leishmania braziliensis are intracellular parasites that cause unique clinical forms of cutaneous leishmaniasis. Previous studies with other leishmania species demonstrated that reactive oxygen species (ROS) control promastigotes, the infective stage of the parasite, but not the amastigote form that exists in the mammalian host. Here we show that ROS inhibits growth of L. braziliensis amastigot...

BACKGROUND Leishmaniasis remains a global health problem because of the substantial holes that remain in our understanding of sand fly ecology and the failure of traditional vector control methods. The specific larval food source is unknown for all but a few sand fly species, and this is particularly true for the vectors of Leishmania parasites. We provide methods and materials that could be us...

has been observed only in imported dogs and as a consequence no preventive measures are possible. In areas where the disease is commonly encountered, however, control measures are directed against sandflies, which transmit the parasites. Although phenamidine has been used in the treatment of leishmaniasis, relapses are common and specific medication is generally unsatisfactory. The only tremato...

The term leishmaniasis comprises a group of diseases caused by different species of a protozoon called Leishmania. Leishmaniasis is found worldwide, and is considered to be endemic in 88 countries. There are three main clinical forms of leishmaniasis: visceral leishmaniasis, cutaneous leishmaniasis and mucocutaneous leishmaniasis. Exclusive involvement of the mucosa is very rare. We present a s...

BACKGROUND In Brazil Leishmania braziliensis and L. infantum are the principal species responsible for cutaneous and visceral leishmaniases, respectively. Domestic dogs are the main reservoirs of visceral leishmaniasis, while rodents and marsupials are the main reservoirs for cutaneous leishmaniasis. It has also been suggested that dogs could play a role in transmission of cutaneous leishmanias...
