Thymoquinone Effect on Leishmania tropica/infantum and Leishmania-Infected Macrophages
Acta Parasitologica, 2023Leishmania is a parasitic protozoan that tries to enter and amplify within macrophages. Macrophage cells are also immune defense cells that phagocyte many microbes like bacteria, fungi, as well as parasites like Leishmania spp. However, they are unable to kill this parasite that resides in the phagosomes of contaminated macrophages and multiplies in ...

Leishmania tropica and Leishmania mexicana: Cross-immunity in mice
Experimental Parasitology, 1978Abstract The effect of a previous or concurrent Leishmania tropica major infection on a L. mexicana infection was studied. Mice which were recovering from or had recovered from a L. tropica infection were found to be totally resistant to L. mexicana. Infection of mice already carrying a L. mexicana infection with L.

Archives of Dermatology, 1977
To the Editor.— The article on Leishmania tropica infections in travellers by Drs Rau, Dubin, and Taylor (112:197, 1976) was an excellent summary of the clinical and pathologic findings of this disease. However, I think that their conclusion not to treat this disease on the basis on four cases and a deficiency in the medical literature should not be ...

Indian kala-azar caused by Leishmania tropica
The Lancet, 1995Kala-azar, or visceral leishmaniasis, in India is generally assumed to be a result of infection with Leishmania donovani. 15 parasite isolates collected over the past 10 years from patients with classical disease were typed by monoclonal antibodies, isoenzymes, and kDNA analysis.

Humoral antibody response in Leishmania tropica infection
Journal of Infection, 1992A small epidemic of Leishmania tropica infection was detected in Rajasthan, India. Most cases were in the 21-25 years age group and were possibly related to outdoor activity. Nearly one third of the patients had more than five lesions, the maximum number of lesions being confined to the face, neck and extremities.

The Metabolism of Leishmania Tropica
Journal of Infectious Diseases, 1928An extensive literature dealing with the metabolism of bacteria has accumulated, but so far, little work has been carried out on the metabolic activities of the protozoa. The protozoologist's inability to grow the latter for many generations, has been and still is one of the difficulties in the way.

Leishmania tropica: Uptake of methionine by promastigotes
Experimental Parasitology, 1977Abstract Promastigotes of Leishmania tropica transport methionine against a concentration gradient through a saturable system. This concentrative uptake requires metabolic energy and is sensitive to temperature and sulfhydryl reagents such as N -ethyl maleimide. Intracellular methionine exchanges with external methionine.

Intracellular protein degradation in Leishmania tropica promastigotes
Molecular and Biochemical Parasitology, 1983Abstract A labile class of proteins in the range of M r = 30 000–60 000 which turn over rapidly have been demonstrated in Leishmania tropica promastigotes. The rate of protein degradation is increased by exhaustion of nutrients or inhibition of energy metabolism.
