A novel A2 allele found in Leishmania (Leishmania) infantum chagasi Novo alelo do gene A2 descrito em Leishmania (Leishmania) infantum chagasi [PDF]

Revista Brasileira de Parasitologia Veterinária, 2011
Visceral leishmaniasis (VL) is a widely spread zoonotic disease. In Brazil the disease is caused by Leishmania (Leishmania) infantum chagasi. Peridomestic sandflies acquire the etiological agent by feeding on blood of infected reservoir animals, such as ...

Transmission of Leishmania infantum from cats to dogs [PDF]

Revista Brasileira de Parasitologia Veterinária, 2020
Leishmania infantum infection in cats has been reported in several countries, including Brazil. However, the transmission of visceral leishmaniasis (VL) from cats to another host has not been proven yet. Therefore, the aim of this study was to verify the

Leishmania infantum in the reproductive organs of dogs [PDF]

Ciência Rural, 2021
ABSTRACT: Leishmania infantum causes canine leishmaniasis. Using parasitological and molecular analyses, we identified L. infantum in the reproductive organs of male and female dogs. Using histochemistry, immunohistochemistry, and PCR, we examined tissue samples from the reproductive organs of 8 male dogs and 16 female dogs diagnosed with leishmaniasis.

Detection of Leishmania tarentolae in lizards, sand flies and dogs in southern Italy, where Leishmania infantum is endemic: hindrances and opportunities

Parasites & Vectors, 2021
Background Leishmania tarentolae is a protozoan isolated from geckoes ( Tarentola annularis , Tarentola mauritanica ), which is considered non-pathogenic and is transmitted by herpetophilic Sergentomyia spp. sand flies.

Identification of Chalcone Derivatives as Inhibitors of Leishmania infantum Arginase and Promising Antileishmanial Agents

Frontiers in Chemistry, 2021
Arginase catalyzes the hydrolysis of l-arginine into l-ornithine and urea, acting as a key enzyme in the biosynthesis of polyamines. Leishmania growth and survival is dependent on polyamine biosynthesis; therefore, inhibition of Leishmania arginase may ...

A Case of Leishmania Infantum Mimicking Lymphoma

Indian Journal of Dermatology, 2023
Leishmaniasis is a parasitic infection caused by an obligate intracellular protozoon transmitted by infected sand flies. Cutaneous leishmaniasis (CL) is a skin disease known in our country as oriental sore, which heals, leaving a scar in place, mainly on the skin and sometimes in the mucous membrane.

Genes and Chromosomes of Leishmania infantum [PDF]

Memórias do Instituto Oswaldo Cruz, 1997
During recent years, several Leishmania infantum genes have been cloned and characterized. Here, we have summarized the available information on the gene organization and expression in this protozoan parasite. From a comparative analysis, the following outstanding features were found to be common to most of the genes characterized: tandemly organized ...

Study of ocular manifestations and humoral immune response in eyes of dogs with leishmaniasis

Veterinary Medicine and Science, 2023
Background Ocular manifestations in dogs with leishmaniasis are frequent and complications in affected tissues can lead to blindness. Immune processes play a very important role in the pathogenesis of ocular inflammation.

Serological and Molecular Survey of Leishmania infantum in a Population of Iberian Lynxes (Lynx pardinus)

Microorganisms, 2022
Leishmania infantum, the sand fly-transmitted protozoan parasite responsible for leishmaniasis in humans, dogs, and cats, is endemic in the Iberian Peninsula. However, the impact of L. infantum infection on the conservation of the endangered Iberian lynx

Colonization and genetic diversification processes of Leishmania infantum in the Americas

Communications Biology, 2021
Leishmania infantum causes visceral leishmaniasis, a deadly vector-borne disease introduced to the Americas during the colonial era. This non-native trypanosomatid parasite has since established widespread transmission cycles using alternative vectors ...
