Development of Leishmania (Leishmania) infantum chagasi in Its Natural Sandfly Vector Lutzomyia longipalpis [PDF]

The American Society of Tropical Medicine and Hygiene, 2012
We analyzed the development of Leishmania (Leishmania) infantum chagasi in its natural sandfly vector Lutzomyia longipalpis. In addition, we compared sandfly infections initiated with axenic amastigotes or promastigotes. Our data showed no important difference between Lu. longipalpis infection rates resulting from either type of infections. Furthermore,

New record of preclinical diagnosis of American visceral leishmaniasis in Amazonian Brazil encourages optimizing disease control

Parasite Epidemiology and Control, 2020
The clinical-immunological spectrum of human Leishmania (L.) infantum chagasi-infection in Amazonian Brazil has recently been reviewed based on the combined use of the delayed-type hypersensitivity (DTH) and indirect fluorescence antibody test (IFAT-IgG ...

Biodistribution of meglumine antimoniate in healthy and Leishmania (Leishmania) infantum chagasi-infected BALB/c mice [PDF]

Memórias do Instituto Oswaldo Cruz, 2013
Pentavalent antimonials such as meglumine antimoniate (MA) are the primary treatments for leishmaniasis, a complex disease caused by protozoan parasites of the genus Leishmania . Despite over 70 years of clinical use, their mechanisms of action, toxicity and pharmacokinetics have not been fully elucidated.

Leishmania infantum chagasi in northeastern Brazil: asymptomatic infection at the urban perimeter. [PDF]

Am J Trop Med Hyg, 2012
Visceral leishmaniasis (VL) is endemic in large cities in Brazil, including Natal. We determined the prevalence of asymptomatic human infection with Leishmania infantum chagasi and associated environmental risks around Natal. Infection was detected by Leishmania skin test (LST) and anti-leishmanial antibodies in humans and anti-leishmanial antibodies ...

Design of primer pairs for species-specific diagnosis of Leishmania (Leishmania) infantum chagasi using PCR [PDF]

Revista Brasileira de Parasitologia Veterinária, 2012
The objective of this study was to design and evaluate new primers for species-specific detection of L. infantum chagasi using PCR. Two combinations of primer pairs were established with the aim of obtaining specific amplification products from the L. infantum chagasi 18S rRNA gene.
