Respiration of Leishmania mexicana amastigotes and promastigotes
Molecular and Biochemical Parasitology, 1981Promastigotes of Leishmania mexicana mexicana recently derived from amastigotes by transformation in vitro respired at a rate (17 nmol O2/min per 10(8) parasites) 4-5 times higher than that of amastigotes, but when the difference in cell protein content between the two preparations was taken into account the rates were not significantly different (32 ...

Leishmania mexicana: Amastigote hydrolases in unusual lysosomes
Experimental Parasitology, 1986Leishmania mexicana mexicana (M379) amastigotes were found to contain much higher activities than cultured promastigotes of five putative lysosomal enzymes: cysteine proteinase; arylsulfatase (EC 3.1.6.1); beta-glucuronidase (EC 3.2.1.31); DNase (EC 3.1.22.1), and RNase (EC 3.1.27.1).

The glycolytic enzyme glucosephosphate isomerase (PGI) is present in two different cell compartments of Leishmania mexicana promastigotes; more than 90% of the activity was detected in the cytosol, the remainder in glycosomes. This subcellular distribution contrasts with that in Trypanosoma brucei, in which the enzyme activity has been mainly located ...

Abstract The effect of certain inoculation conditions on the incubation period and development of cutaneous Leishmania braziliensis and Leishmania mexicana lesions was determined in golden hamsters infected in multiple sites. These conditions included: use of the nose, ear, forepaw, and flank as sites of inoculation; use of the intradermal and ...

Leishmania mexicana and Leishmania tropica: Cross immunity in C57BL/6 mice
Experimental Parasitology, 1979Abstract Leishmania mexicana and Leishmania tropica infection were comparatively studied in C57BL/6 mice. Infection with 10 4 amastigotes of L. mexicana was followed by the appearance of a single lesion which ulcerated in 8 weeks and healed in 24 weeks. Mice infected with 10 4 amastigotes of L.

The particulate activities of Leishmania mexicana mexicana amastigote malate dehydrogenase (L-malate:NAD+ oxidoreductase, EC 1.1.1.37) and phosphoenolpyruvate carboxykinase (ATP:oxaloacetate carboxy-lyase (transphosphorylating) EC 4.1.1.49) have been purified to apparent electrophoretic homogeneity by hydrophobic interaction chromatography using Phenyl-

Leishmania tropica (Wright 1903) and Leishmania mexicana (Biagi 1953)
1995The genus Leishmania has been the subject of much current taxonomic and clinical research.1 Through the use of DNA probes, ELISA tests, and differential respirometry, new species and subspecies of Leishmania have been identified and partially characterized.2 Although taxonomy has introduced new species of this genus, from the clinical point of view ...

Evidence for a Membrane Adenosine Receptor in Leishmania Mexicana Mexicana (WR 227)
1986Leishmania spp., a Protozoan Parasite transmitted to the mammalian host by the sand fly (genus Phlebotomus), produces a disease manifested in the cutaneous, mucocutaneous or visceral form. The choice of drugs has been limited primarily to the pentavalent antimonial compounds.

[Production of monoclonal antibodies against Leishmania mexicana mexicana antigens].
Acta cientifica venezolana, 1993In the present work we obtained three mAbs specific against gp65 of the strain L. mexicana mexicana (NR). These three mAbs were able of recognizing promastigotes of L.m.m. not only for immunofluorescence but also by immunostain. In the immunohistochemistry of biopsies of patients with leishmaniasis, using the three mAbs, it was possible to observe the ...
