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.

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 ...

Case series: Kikuchi‐Fujimoto disease with diagnostic overlap

open access: yesRheumatology &Autoimmunity, EarlyView.
Kikuchi‐Fujimoto disease (KFD) is a rare, self‐limiting necrotizing lymphadenitis that poses significant diagnostic challenges due to its overlap with tuberculosis, systemic lupus erythematosus (SLE), and malignancy. We present four cases highlighting distinct diagnostic complexities: KFD mimicking tuberculosis with concomitant latent TB infection and ...

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.

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Structural basis of ligand selectivity in FAD/NAD(P)H‐dependent dehydrogenases: insights from trypanothione reductase and type II NADH dehydrogenase

open access: yesProtein Science, Volume 35, Issue 7, July 2026.
Abstract FAD/NAD(P)H‐dependent dehydrogenases form a structurally conserved family of redox enzymes that participate in essential metabolic processes across parasites and higher organisms. Among them, trypanothione reductase (TR) is a key component of the redox metabolism of Leishmania species and represents an attractive target for antileishmanial ...

Microbial Pressure and Social Immunity: Bumble Bees Increase Brood Hygiene After Exposure to a Bacillus thuringiensis‐Based Biopesticide

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
In social insect colonies, diseased or dead brood is identified and removed by workers to prevent the infection of the whole colony. Here, bumble bee larvae exposed to a bacterium (Bacillus thuringiensis ssp. aizawai (strain: ABTS‐1857)) based biopesticide were removed more frequently than wounded or untreated control larvae. This shows that bumble bee
