Comparative Transcriptomics of the Bovine Apicomplexan Parasite Theileria parva Developmental Stages Reveals Massive Gene Expression Variation and Potential Vaccine Antigens

Frontiers in Veterinary Science, 2020
Theileria parva is a protozoan parasite that causes East Coast fever (ECF), an economically important disease of cattle in Africa. It is transmitted mainly by the tick Rhipicephalus appendiculatus.

Extracellular Vesicles of Giardia duodenalis: Unravelling Their Virulence Factors and Potential to Induce Protection Against Experimental Giardiasis

Journal of Extracellular Biology, Volume 5, Issue 6, June 2026.
ABSTRACT Extracellular vesicles (EVs) are key mediators of intercellular communication, enabling trans‐kingdom exchange of proteins, nucleic acids, lipids, and metabolites. In Giardia duodenalis, EVs contribute to parasite survival, host–pathogen interactions, and immune modulation.

Successful in vitro propagation of feline coronavirus from clinically diagnosed feline infectious peritonitis cases using Vero cells: A potential model for future research

Veterinary Record Open, Volume 13, Issue 1, June 2026.
Abstract Background Feline coronavirus (FCoV) causes inapparent to progressive fatal feline infectious peritonitis (FIP) in domestic and wild cats, which affects multiple‐organ systems. Methods We investigated three clinically sick cats using different laboratory and molecular tests to diagnose and confirm FCoV and propagate the virus in Vero cell ...

Alpha 2 giardin is an assemblage A-specific protein of human infective Giardia duodenalis

, 2008
Of the 7 genetic assemblages of the parasite Giardia duodenalis only 2 (A and B) are known to cause infections in humans. These assemblages have been characterized in detail at the genomic level but few studies have examined differences in the proteins ...

Relationships Between European Wildcats and Domestic Cats in an Area of Sympatry: Exploring Key Conservation Questions on Hybridization and Disease Transmission

Animal Conservation, Volume 29, Issue 3, Page 321-333, June 2026.
We have found evidence of behavioural barriers for both hybridization and disease transmission between European wildcats and domestic cats. This includes hierarchical interspecies exclusion enforced by wildcats, as well as sexual selection exerted by wildcat females.

Characterization of T cell clones from chagasic patients: predominance of CD8 surface phenotype in clones from patients with pathology

Memorias do Instituto Oswaldo Cruz, 1995
Human Chagas' disease, caused by the protozoan Trypanosoma cruzi, is associated with pathological processes whose mechanisms are not known. To address this question, T cell lines were developed from chronic chagasic patients peripheral blood mononuclear ...

Evaluation of the Cutaneous Immunological Milieu Before and After Treatment With Meglumine Antimoniate in Dogs Naturally Affected by Leishmaniosis due to Leishmania infantum

Veterinary Dermatology, Volume 37, Issue 3, Page 455-463, June 2026.
Background: Canine leishmaniosis (CanL) is a zoonotic disease of variable severity. The typical immune response is driven by an exaggerated humoral immune response. Protective immunity is mediated by pro‐inflammatory cytokines that enhance macrophage leishmanicidal activity. Objective: To evaluate the cutaneous and the systemic immune responses as well
