Immune priming of honey bees protects against a major microsporidian pathogen

open access: yesPest Management Science, Volume 81, Issue 12, Page 7939-7949, December 2025.
We immune‐primed honey bees at two developmental stages in the laboratory and the field with heat‐killed Nosema ceranae spores. When subsequently fed live spores, immune‐primed adults had lower infection levels. Abstract BACKGROUND Honey bees face significant threats from pathogens like Nosema ceranae, a microsporidian parasite that contributes to ...

Delineating neuroinflammation, parasite CNS invasion, and blood-brain barrier dysfunction in an experimental murine model of human African trypanosomiasis [PDF]

open access: yes, 2017
Although Trypanosoma brucei spp. was first detected by Aldo Castellani in CSF samples taken from sleeping sickness patients over a century ago there is still a great deal of debate surrounding the timing, route and effects of transmigration of the ...

Phylogenetic and morphological characterization of trypanosomes from Brazilian armoured catfishes and leeches reveal high species diversity, mixed infections and a new fish trypanosome species

open access: yesParasites & Vectors, 2015
Several Trypanosoma species transmitted by leeches infect marine and freshwater fish worldwide. To date, all South American fish trypanosome species identified have been based on unreliable morphological parameters.

Highly divergent apicomplexan cytoskeletons provide additional models for actin biology

open access: yesThe FEBS Journal, Volume 292, Issue 24, Page 6459-6480, December 2025.
Actin is a highly conserved, abundant and central molecule in eukaryotes. Apicomplexans contain some of the most sequence‐divergent actin cytoskeletons known. This divergence results in overlapping yet different biochemical properties. Here, we highlight the remarkable divergence of the actin cytoskeleton by comparing apicomplexan to classical systems,

Assembling the components of the quorum sensing pathway in African trypanosomes

open access: yesMolecular Microbiology, 2015
African trypanosomes, parasites that cause human sleeping sickness, undergo a density‐dependent differentiation in the bloodstream of their mammalian hosts.

Arthropod ectoparasites of synanthropic rodents in northern‐central Italy

open access: yesMedical and Veterinary Entomology, Volume 39, Issue 4, Page 787-793, December 2025.
The presence of ectoparasites in synanthropic rodents in various Italian provinces was investigated. Eighty‐one Rattus norvegicus, 49 Rattus rattus and 10 Mus musculus were examined Polyplax spinulosa lice, Myobiidae mites, Laelaps echidninus and Notoedres muris were mainly recovered.

Intravital Imaging of a Massive Lymphocyte Response in the Cortical Dura of Mice after Peripheral Infection by Trypanosomes

open access: yesPLoS Neglected Tropical Diseases, 2015
Peripheral infection by Trypanosoma brucei, the protozoan responsible for sleeping sickness, activates lymphocytes, and, at later stages, causes meningoencephalitis.

Bioactivity Profiles of Progressively Ring‐Fluorinated Cyclohexyl Motifs in the WKYMVm Peptide as Formylpeptide FPR2 Agonists and in Keto‐Piperazines as Antitrypanosome Agents

open access: yesChemBioChem, Volume 26, Issue 22, November 17, 2025.
All‐cis‐fluorinated cyclohexyl motifs with progressively increasing levels of fluorine are introduced into the WKYMVm peptide and a class of keto‐piperazine derivatives and assayed against the FPR2 receptor or the parasite Trypanosoma brucei, respectively.
