Synthesis of unsaturated fatty acids in the slime mold Physarum polycephalum and the zooflagellates Leishmania tarentolae, Trypanosoma lewisi, and Crithidia sp.: a comparative study

open access: yesJournal of Lipid Research, 1965
On the basis of the unsaturated fatty acids which they synthesize, protists can be grouped in a meaningful way. Thus, the unsaturated fatty acids of the true slime mold are identical with the unsaturated fatty acids of the soil amoebae Acanthamoeba and ...

Host Detection by Cuckoo Bumblebees: Choice Experiments Reveal Non‐Visual Cues Support Host Detection, but Accuracy Is Low

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Female Bombus vestalis cuckoo bumblebees were introduced to a flight arena containing four identical opaque boxes, featuring slits to release volatiles from the bumblebees inside. When only one box contained a developing host colony, the cuckoos were able to locate their hosts among the four boxes with 66.2% accuracy.

The genomes of Crithidia bombi and C. expoeki, common parasites of bumblebees. [PDF]

open access: yesPLoS ONE, 2018
Trypanosomatids (Trypanosomatidae, Kinetoplastida) are flagellated protozoa containing many parasites of medical or agricultural importance. Among those, Crithidia bombi and C.

Common pathways and outliers in glucose catabolism across Trypanosomatidae

open access: yesThe FEBS Journal, EarlyView.
Trypanosomatid parasites, including Trypanosoma sp., Leishmania sp., Phytomonas sp., and Vickermania sp., share a common motif: a metabolism built around the glycosome, a unique peroxisome‐derived organelle housing the first steps of glycolysis. Yet, these organisms have evolved remarkably diverse strategies to catabolize glucose, excreting distinct ...

Large circular mitochondrial DNA in Crithidia luciliae

open access: yes, 1975
A novel circular DNA, 11.3 μm in contour length, has been found in a pure kinetoplast DNA fraction of Crithidia luciliae. The mitochondrial nature of the kinetoplast and the absence of these large circular molecules in the nuclear fraction of DNA suggest

Infection of a mammal by monogenetic insect trypanosomatids (Kinetoplastida, trypanosomatidae)

open access: yesMemorias do Instituto Oswaldo Cruz, 1988
Monogenetic insect trypanosomatids of the genera Crithidia, Leptomonas and Herpetomonas, multiplied as in axenic cultures, for many months, in the lumen of the scent glands of the opossum Didelphis marsupialis.

Structural Insights Into the Function of Leishmania major Adenylosuccinate Lyase

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 10, Page 1686-1701, October 2026.
ABSTRACT One of several intriguing aspects of kinetoplastid biochemistry is the complete dependence on host purines and purine recycling due to the lack of a de novo purine biosynthesis pathway. Adenylosuccinate lyase (ASL, EC 4.3.2.2) is a key enzyme in the purine synthesis pathway responsible for the conversion of adenylosuccinate into adenosine ...

Molecular and phylogenetic characterization of honey bee viruses, Nosema microsporidia, protozoan parasites, and parasitic mites in China [PDF]

open access: yes, 2013
China has the largest number of managed honey bee colonies, which produce the highest quantity of honey and royal jelly in the world; however, the presence of honey bee pathogens and parasites has never been rigorously identified in Chinese apiaries.
