Toxicity of bilirubin to Leishmania tropica promastigotes

Experimental Parasitology, 1976
Abstract Treatment of Leishmania tropica promastigotes with bilirubin results in loss of viability and death of the cells. A concentration of 0.1 m M is sufficient to cause complete inhibition of growth. Bilirubin inhibits the uptake of 2-deoxy- d -glucose and l -methionine. It increases the efflux of intracellularly accumulated sugars (both free

Characterization of RNA from Leishmania tropica and Leishmania d. donovani promastigotes

Molecular and Biochemical Parasitology, 1987
RNA has been prepared from promastigotes of Leishmania tropica and Leishmania d.donovani using three different methods. Extraction by hot phenol/isothiocyanate gave the best quantitative and qualitative results. The analysis of total RNA on methyl mercuric agarose gels shows that the large rRNA species is nicked: it is composed of a 630 and a 560 kDa ...

Coexistence of Leishmania tropica and Leishmania infantum in Sefrou province, Morocco

Acta Tropica, 2014
Cutaneous leishmaniasis (CL) has been recently emerged in new foci, posing a public health problem. Increasing cases of CL have been reported during recent years in Sefrou province, a previously non-endemic area. The present study was designed for epidemiological and parasitological characterization of the disease for the first time in this area.

Leishmania mexicana and Leishmania tropica: Cross immunity in C57BL/6 mice

Experimental Parasitology, 1979
Abstract 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.

Cutaneous leishmaniasis caused by Leishmania tropica in Algeria

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2008
Cutaneous leishmaniasis is endemic in Algeria, but clinical and parasitological data from this area are scarce. In order to document the transmission of this disease in a peri-urban setting, cutaneous lesions from patients living in Constantine City and surrounding areas were spotted on filter paper for diagnosis and species identification using real ...

Leishmania tropica in Egypt: an undesirable import

Tropical Medicine & International Health, 1996
SummaryCutaneous as well as visceral leishmaniasis has been previously reported in Egypt. The former clinical manifestation is attributed to Leishmania major, the latter to L. infantum. In this study, L. tropica was isolated from an Egyptian labourer returning from Saudi Arabia.

Leishmania tropica (Wright 1903) and Leishmania mexicana (Biagi 1953)

1995
The 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 ...

Leishmania tropica ve Středomoří

2010
In recent years new foci of Leishmania tropica appeared in the Mediterranean states of Northern Africa. While L. tropica was isolated from humans, dogs and sand fly species Phlebotomus sergenti in Morocco and from humans and gerbils (Gerbilus pyramidum floweri) in Egypt; in Tunisia, Algeria and Lybia the parasite was isolated from humans only.

Biochemical Reactions of Leishmania Tropica 1

The American Journal of Tropical Medicine and Hygiene, 1939
Summary and Conclusions Seven locally isolated strains of Leishmania tropica were uniform in their biochemical reactions, i.e. 1.  No production of acid or gas from carbohydrates, 2.  No liquifaction of gelatin, 3.  Methyl red reaction was negative, 4.  Voges Prauskauer reaction was negative, 5.  Peptonization of milk, 6.  Bile soluble, 7.
