Circulating extracellular vesicles across bovine gestation conserve characteristics independently of fetal age and sex
IntroductionExtracellular vesicles (EVs) are released by cells into extracellular space and play a key role in intercellular communication. During pregnancy, embryo- and placenta-derived EVs are present in the maternal circulation, where they can serve as biomarkers of pregnancy status.MethodsThe present study aimed to characterize the circulating EVs in pregnant cows carrying male or female calves. Crossbred Angus cows were subjected to Timed- Artificial Insemination (TAI) u

A pilot study investigating the comparison of immunological responses to two immunosuppressive regimens in a porcine model
Effective immunosuppression in large animal models is essential for successful preclinical assessment of cell-based therapies in the allo- or xeno-transplantation setting. Pigs, due to their physiological and immunological similarity to humans, are widely used in translational research. However, direct, longitudinal comparisons of immunosuppressive strategies in swine are scarce, limiting the development of safe and reliable protocols. To address this gap, we performed a head

Progress in the application of traditional Chinese medicine and natural products for the prevention and treatment of calf diarrhea: a review
Calf diarrhea is a common and severe disease in the livestock industry, leading to poor growth and high mortality rates in calves, thereby causing significant economic losses. With increasing concerns over antibiotic resistance, traditional Chinese medicine (TCM) and natural products have garnered widespread attention as alternative therapeutic options for managing calf diarrhea. This review systematically summarizes recent advances in the utilization of TCM, natural products

Qualitative behavioural assessment shows individual variation suggestive of affective state changes in early lactation dairy cows
Qualitative behavioural assessment (QBA) is described as a ‘whole animal’ approach for evaluating welfare through posture and behaviour to judge their emotional state. Although QBA has been applied in dairy cows for a population-level assessment, its use in evaluating individual cattle remains limited. Given the current limitations in evaluating the affective state in cows, validated methods are needed, including the assessment of QBA, for the assessment at the individual lev

Evaluation of an E2-based indirect ELISA for the serological differentiation of ovine Italy pestivirus from classical swine fever virus in pigs
The genus Pestivirus includes several species responsible for economically important diseases in domestic and wild animals. In 2017, a novel ovine pestivirus (ovIT PeV) was isolated from aborted lamb fetuses and molecular analysis showed a genetic distinction from known Pestivirus species with the closest phylogenetic relationship to classical swine fever virus (CSFV, Pestivirus suis). This close similarity is concerning because CSF is a notifiable disease to the World Organi

MiR-1 mediates autophagy via ATG14 in sheep Leydig cells infected with Brucella melitensis strain BA0711
Brucella spp. achieve intracellular parasitism by hijacking host autophagy pathways. Sheep Leydig cells (SLCs) are important intracellular parasitic target cells for Brucella melitensis (B. melitensis). To investigate the molecular regulatory network induced by B. melitensis in SLCs, particularly whether the autophagic pathway response differs from that in other cell types, transcriptome sequencing analysis was performed on SLCs treated with B. melitensis BA0711.

Overview of waterfowl circovirus: research progress and future perspectives
Waterfowl circovirus (WFCV) is an important member of the genus Circovirus within the family Circoviridae, encompassing duck circovirus (DuCV) and goose circovirus (GoCV). As a pathogen that poses a serious threat to the global waterfowl industry, WFCV induces significant immunosuppression in its hosts, leading to growth retardation, feather abnormalities, and increased susceptibility to other pathogens. Consequently, it results in markedly elevated mortality rates among affe
