Struvite Precipitation by Trypanosoma cruzi
The Journal of Parasitology, 1987It has been previously reported that some microorganisms in culture possess the capacity to generate exocellular mineral crystals. Some species of bacteria are able to produce crystals such as aragonite, calcite, apatite, stroncianite, and struvite (Greenfield, 1963, Annals of the New York Academy of Science 109: 23-45; Ennever et al., 1974, Journal of

Fatty acids of Trypanosoma cruzi
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19821. The fatty acid pattern of total lipids from T. cruzi is different from one of its growth medium. 2. The distribution of major fatty acids in phospholipid fraction was linoleic (50.4%), oleic (25.6%), stearic (10.1%) and palmitic (6.3%) and in neutral lipid fraction oleic and linolelc (about 29% each), palmitic (18.3%) and stearic (9.8%). 3.

Purine metabolism in Trypanosoma cruzi
Molecular and Biochemical Parasitology, 1981Culture forms of Trypanosoma cruzi are incapable of synthesizing purines de novo from formate, glycine, or serine and require an exogenous purine for growth. Adenine, hypoxanthine, guanine, xanthine and their respective ribonucleosides are equal in their abilities to support growth.

An immunocytotoxic assay for Trypanosoma cruzi
International Journal for Parasitology, 1976Abstract Trypanosoma cruzi culture forms grown for 8 days in LIT medium fortified with 14C-labeled amino acids will incorporate the isotope into membranous and soluble components of the parasite. On lysis, labeled cytoplasmic elements released into the surrounding medium can be measured and reflect the degree of destruction of the parasites ...

Catabolic metabolism in Trypanosoma cruzi
International Journal for Parasitology, 1980Abstract Culture, blood and intracellular forms of Trypanosoma cruzi have a high rate of endogenous oxygen uptake and probably utilize amino acids and carbohydrates as their exogenous energy sources. It is likely that triglyceride is the main energy reserve. Oxidation of carbohydrate by all forms is probably via a glycolytic sequence and a complete

Intermediary metabolism of Trypanosoma cruzi
Parasitology Today, 1994In this article, Julio Urbino discusses the characteristics o f the intermediary metabolism of Trypanosoma cruzi (the causative agent of Chagas disease), which are responsible for the unusual capacity of this parasite to use carbohydrates or amino acids as carbon and energy sources without drastic changes in its catabolic enzyme levels(1-3).

TRYPANOSOMA CRUZI CRUZI IN THE TISSUES OF THE ARMADILLO
JAMA: The Journal of the American Medical Association, 1923In 1912, Chagas 1 reported finding Trypanosoma cruzi in the hind gut of Triatoma geniculata , which was collected in the burrows of the armadillo ( Tatusia novemcincta ) in the zone in which American trypanosomiasis is endemic. Following this he found the trypanosomes in the blood of the armadillo, from which he was able to infect guinea-pigs, and ...

Reservosomes of Trypanosoma cruzi
2010Reservosomes are lysosome-related organelles (LROs) of Trypanosoma cruzi with the special capacity of nutrient storage and hydrolase accumulation. They represent the final compartment of epimastigote endocytic pathway and the site of activity of cruzipain, the major T. cruzi protease.

Signaling in Trypanosoma cruzi
2003Many signaling pathways known to be present in metazoans are also present in unicellular organisms, and Trypanosoma cruzi is not an exception. T. cruzi shares key molecules and biochemical pathways with higher eukaryotes. For example, calcium, adenylyl cyclase, guanylyl cyclase, phospholipase C, nitric oxide synthase, protein kinases, and protein ...

Signal Transduction in Trypanosoma cruzi
2011Signal transduction plays a key role in regulating important functions in both multicellular and unicellular organisms and largely controls the manner in which cells respond to stimuli. Signal transduction pathways coordinate the functions in different type of cells in animals and control the growth and differentiation in unicellular organisms ...
