Leishmania (Viannia) panamensis/Leishmania (Leishmania) amazonensis—A Warning
Parasitology Today, 1999The parasite Leishmania (Viannia) panamensis causes local cutaneous lesions. The Laboratory of Infectious Disease Pathology of the University of Sao Paulo Medical School has been working with a strain of Leishmania (Viannia) panamensis, HSJD-1, characterized by isoenzyme at the Liverpool School of Tropical Medicine, by W.

The Lipophosphoglycan of Leishmania
Parasitology Today, 1988The major cell surface glycoconjugate of leishmanial parasites is lipophosphoglycan (LPG). Its relative abundance, unique structure, and cellular location suggest one or more important roles in interactions between parasites and host cells. In this article, Sam Turco examines current information about this novel glycoconjugate and its significance.

Parasitology Today, 1992
Chromosome size polymorphisms occur in Leishmania such that each strain of a given species has a distinctive molecular karyotype. Despite this variability, the chromosomal similarities among closely related strains of Leishmania are sufficiently characteristic to permit classification of unidentified clinical isolates.

Veterinary Parasitology, 2007
Leishmania parasites cause a group of diseases collectively known as leishmaniases. The primary hosts of Leishmania are sylvatic mammals of several orders (Rodentia, Marsupialia, Carnivora, etc.). Under certain circumstances, particularly in peridomestic and domestic transmission foci, synanthropic and domestic animals can act as source of infection ...

The presence of different sets of several enzymes that participate in the Krebs-Henseleit cycle has been used to identify several genera of trypanosomatids. One of these enzymes is arginase (L-arginine amidinohydrolase, E.C. 3.5.3.1), a metalloenzyme that catalyzes the hydrolysis of L-arginine to L-ornithine and urea.

Leishmania (Leishmania) chagasi is not vertically transmitted in dogs
Veterinary Parasitology, 2002The most frequent and most important mode of human or canine visceral leishmaniasis (CVL) transmission is through the bite of infected sand flies. This study investigates Leishmania (Leishmania) chagasi vertical transmission in offspring of naturally infected dogs. Thus 63 puppies from 18 female dogs with CVL were used.

Characterization of Leishmania (Leishmania) tropica axenic amastigotes
Acta Tropica, 2010Optimum conditions for generating Leishmania (Leishmania) tropica axenic amastigotes (AxA) in culture were determined, pH 5.5/36 degrees C, and the parasites characterized by different techniques, including light microscopy, macrophage infection, stage specific antigen expression and differential display. AxA were morphologically similar to amastigotes

Leishmania RNA Viruses in Leishmania of the Viannia Subgenus
The American Journal of Tropical Medicine and Hygiene, 1996Karyotype analysis of 69 strains of Leishmania belonging to three species of the Viannia subgenus originating from the southeastern and southwestern regions of Colombia revealed approximately 5.3-kb RNAs in four strains of L. braziliensis and also in the World Health Organization reference strain L. guyanensis IWHI/BR/78/M5313.

Purine metabolism in Leishmania donovani and Leishmania braziliensis
Biochimica et Biophysica Acta (BBA) - General Subjects, 1978We have studied purine metabolism in the culture forms of Leishmania donovani and Leishmania braziliensis. These organisms are incapable of synthesizing purines de novo from glycine, serine, or formate and require an exogenous purine for growth. This requirement is better satisfied by adenosine or hypoxanthine than by guanosine.

Proteophosphoglycans of Leishmania
Parasitology Today, 2000Proteophosphoglycans are an expanding family of highly glycosylated Leishmania proteins with many unusual and some unique structural features. The novel protein-glycan linkage in proteophosphoglycans - phosphoglycosylation of Ser by lipophosphoglycan-like structures - emerges as a major form of protein glycosylation in Leishmania.
