30 Brazilian stocks of Leishmania mexicana amazonensis and 13 stocks of subspecies of Leishmania hertigi were characterized by starch-gel electrophoresis, using 18 enzymes selected from a total of 36 investigated. L. m. amazonensis was separable from subspecies of L. hertigi by enzymic profiles of 11 enzymes. The L. m.

The first documented human case of visceral leishmaniasis caused by L. mexicana amazonensis is reported. Leishmania were isolated from bone marrow aspirate material from a typical visceral leishmaniasis patient. Further characterization by isoenzyme electrophoresis and by a panel of species- and subspecies-specific monoclonal antibodies established its

The Comparative Genomics and Phylogenomics of Leishmania Amazonensis Parasite [PDF]
Evolutionary Bioinformatics, 2014 Leishmaniasis is an infectious disease caused by Leishmania species. Leishmania amazonensis is a New World Leishmania species belonging to the Mexicana complex, which is able to cause all types of leishmaniasis infections. The L.

Heme binding to Leishmania mexicana amazonensis
Molecular and Biochemical Parasitology, 1988Leishmania mexicana amazonensis is a pathogenic parasite whose growth, due to a biosynthetic deficiency, is dependent on a supply of exogenous heme. Utilizing [55Fe]hemin, we have demonstrated that heme binding to non-dividing cultured promastigotes of L. m.

The surface free energy ofLeishmania mexicana amazonensis
Cell Biophysics, 1990Surface charge of Leishmania mexicana amazonensis was investigated by direct zeta-potential determination and ultrastructural cytochemistry, and its surface tension was studied by measurements of the advancing contact angle formed by the parasite monolayers with drops of liquids of different polarities.

Leishmania mexicana amazonensis: Surface charge of amastigote and promastigote forms
Experimental Parasitology, 1983The surface charge of Leishmania mexicana amazonensis was evaluated by means of the binding of colloidal iron hydroxyde particles at pH 1.8 and cationized ferritin particles at pH 7.2 to the cell surface, visualizated by electron microscopy and by direct measurements of the electrophoretic mobility of cells suspended in solutions of different pH.

N-Glycosylation as a biochemical basis for virulence in Leishmania mexicana amazonensis
Molecular and Biochemical Parasitology, 1988Promastigotes of Leishmania mexicana amazonensis grown in vitro under different conditions showed variable degrees of virulence, as determined quantitatively by the size of the lesions and the number of intracellular parasites produced in mice and in cultured macrophages, respectively.

Some attempts have been made to isolate intracellular forms of cutaneous leishmaniasis (Childs et al., 1976, J. Parasitol. 62: 676-679; Shaw and Lainson, 1977, J. Parasitol. 63: 384385; Brasil, 1978, Ann. Trop. Med. Parasitol. 72: 379-580; Infante et al., 1980, Parasitology 80:105-112). However, each of these techniques has limitations.

Intracellular forms of Leishmania mexicana amazonensis divide inside the phagocytic vacuole of macrophages. Some parasites attach to the membrane of the phagocytic vacuole while others remain free in the vacuole. Examination of thin sections of the attachment region by electron microscopy revealed a space of 2 nm between the membrane of the phagocytic ...

In order to understand the mechanisms which generate minicircle sequence diversity, we sequenced three minicircles belonging to the same or closely related sequence classes from the kinetoplast DNA of Leishmania mexicana amazonensis strains, PH8, Raimundo, and Josefa.
