Pathogenicity of "Crithidia fasciculata" in the haemocoele of "Glossina"

Acta tropica, 1987
The mosquito flagellate Crithidia fasciculata produces intense haemocoelic infections following intrahaemocoelic inoculation into 5 species of Glossina--G. austeni, G. fuscipes fuscipes, G. morsitans morsitans, G. palpalis gambiensis and G. tachinoides. All Glossina inoculated with C. fasciculata died between days 4 and 9.

The sterols of Trypanosoma cruzi and Crithidia fasciculata

Comparative Biochemistry and Physiology, 1969
Abstract 1. 1. Six sterols have been detected in Trypanosoma cruzi cultured on serum-free medium. Four of these are ergosterol, 22,23-dihydroergosterol, 7-dehydroporiferasterol and 7-dehydroclionasterol (or their C24 isomers from which they cannot be distinguished with the small quantities available).

Effects of Hydroxyurea on Crithidia fasciculata

The Journal of Protozoology, 1979
SYNOPSIS Hydroxyurea (HU) inhibits increase in cell number in cultures of Crithidia fasciculata. Complete inhibition is produced by 8 mM and higher concentrations. If HU is not removed, population growth resumes in 45–50 h: if HU is removed, partially synchronous growth occurs through 2 cycles. During HU inhibition, the rate of DNA synthesis is reduced

The histones of the insect trypanosomatid, Crithidia fasciculata

Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1990
The histone-like proteins of the monogenetic parasite Crithidia fasciculata were extracted with 0.2 M sulfuric acid either from purified nuclei, or from purified chromatin, in both cases in the presence of 1 mM tosyl lysylchloromethylketone and 2 mM phenyl methyl sulfonyl fluoride as proteinase inhibitors.

The origin of unconjugated pteridines in Crithidia fasciculata

Archiv f�r Mikrobiologie, 1967
By using folic acid-2-14C in the growth medium as the sole source of pteridine it was found that the kinetoplastid flagellate, Crithidia fasciculata, produced a total of 87 mμg of labeled biopterin and 23 μg of 2-amino-4-hydroxy-6-hydroxymethylpteridine from 2 mg of folic acid in 2 liters of medium.

Arylamidases of Crithidia fasciculata

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1974
Abstract 1. 1. Crithidia fasciulata was found to be arich source of soluble enzymes hydrolysing the β-naphthylamides of leucine, arginine, lysine and glutamic acid. The specific activities were similar to values observed in mammalian tissues except for higher arylamidase A (α-glu) activity. 2. 2. Arylamidase A (α-glu) was stimulated twofold

The Ribonucleic Acids of Crithidia fasciculata*

The Journal of Protozoology, 1978
SYNOPSIS. Crithidia fasciculata ribosomes were found to be 80S and to dissociate into 58 and 41S subunits; on 5 to 50% sucrose gradients, rRNA was separated into 25, 18, and 5S components. The molecular sizes of the heavier rRNA species, estimated by polyacrylamide gel electrophoresis were 1.24 and 0.84 M (×106 daltons). The 25S RNA has a tendency to

Ectonucleotide diphosphohydrolase activity in Crithidia deanei

Parasitology Research, 2002
In this work we describe the ability of living Crithidia deanei to hydrolyze extracellular ATP. In intact cells at pH 7.2, a low level of ATP hydrolysis was observed in the absence of any divalent metal (0.41+/-0.13 nmol P(i) h(-1) 10(7) cells(-1)). The ATP hydrolysis was stimulated by MgCl(2) and the Mg(2+)-dependent ecto-ATPase activity was 4.05+/-0 ...
