The Ultrastructure of Leishmania donovani
The Journal of Parasitology, 1956The structure of the intracellular form of Leishmania donovani as seen by the light microscope consists of a nucleus and usually a rod-like kinetoplast (Wenyon, 1926) within a homogeneous mass of cytoplasm, while the extracellular or culture form has, in addition to these structures, an anterior flagellum.

Cell surface lipophosphoglycan of Leishmania donovani
Molecular and Biochemical Parasitology, 1987Based on a galactose oxidase/NaB[3H]4 technique of radiolabeling macromolecules, the major glycoconjugate (lipophosphoglycan) of Leishmania donovani promastigotes was determined to be located on the cell surface. Incorporated radioactivity was analyzed by gel filtration on Sephadex G-100, chromatography on ricin agglutinin-coupled agarose, and lability

Lipophosphoglycan Antigen Shedding By Leishmania Donovani
Journal of Eukaryotic Microbiology, 1993ABSTRACT. The biochemical characterizations of lipophosphoglycans from various Leishmania species reported by other workers may or may not contain several types of lipophosphoglycan molecules. This is the first report in which a specific lipophosphoglycan has been defined by both its antigenie and electrophoretic properties. Furthermore, a purification

Leishmania donovani: Hemolytic Activity of Promastigotes
Experimental Parasitology, 1994A hemolytically active component was found to be present in Leishmania donovani promastigotes for the first time. It lysed human and rabbit erythrocytes to varying degrees. The optimal pH for the activity was found to be 5.8. The rate of hemolysis was dependent on both erythrocyte and parasite concentrations.

Glucose transport in Leishmania donovani promastigotes
Molecular and Biochemical Parasitology, 1984Mid-log phase Leishmania donovani promastigotes accumulated 2-deoxy-D-glucose (2-DOG) via a carrier mediated transport system, maintaining an apparent Km of 24.4 microM and a Vmax of 3.12 nmol mg-1 protein min-1. D-Glucose but not L-glucose competitively inhibited the 2-DOG transport with an apparent Ki of 18.7 microM.

Leishmania (Leishmania) donovani subsp. would Nicolle 1908
2020Leishmania (Leishmania) donovani(Laveran et Mesnil, 1903) The record of L. donovani ZMON- 31 in Oman leads us to briefly discuss the taxonomic status and the geographical distribution of this zymodeme and closely related zymodemes. Starting in the 1980s, enzymatic taxonomy studies led to consider the linnean taxa L. donovani and L.

Chromosome size polymorphisms of Leishmania donovani
Molecular and Biochemical Parasitology, 1987A minimum of 22 chromosomes were found in all Leishmania donovani stocks examined by orthogonal field alternation gel electrophoresis (OFAGE). Chromosome sizes ranged from approximately 270 to 4000 kb. Certain chromosomes were polymorphic in size between stocks and chromosomes present in some stocks had no apparent equivalent in others.

Leishmania donovani (Ross 1903)
1995Visceral leishmaniasis, also known as kala-azar, has a wide distribution; no accurate estimate of its prevalence is currently available. The protozoan species that causes visceral leishmaniasis varies according to geographic regions; each has its own unique sandfly vectors and resevoir hosts.1 In India, Bangladesh, Nepal, and China the infection is ...

In Vitro Tryptophan Catabolism by Leishmania donovani donovani Promastigotes
The Journal of Protozoology, 1992ABSTRACT. Metabolism of tryptophan by promastigotes of Leishmania donovani donovani was investigated in cells suspended in a simple buffer solution supplemented with glucose. Metabolites from supernatant and lysed cell pellets were analyzed by capillary gas liquid chromatography and 13C nuclear magnetic resonance spectroscopy, with structural ...

Characterization of strains of Leishmania donovani
Experimental Parasitology, 1966Abstract Even with the most standardized procedures yet available for in vivo trials, the intrastrain variations in the course of infection of Leishmania donovani in the hamster permit no easy assessment of variations among those tested by us from several parts of the world.
