Integrated analysis of transcriptome and milk metagenome in subclinical mastitic and healthy cows [PDF]

Animal Bioscience
Objective Abnormally increased somatic cell counts (SCCs) in milk is usually a sign of bovine subclinical mastitis. Mutual interaction between the host and its associated microbiota plays an important role in developing such diseases.

Epidemic modelling of bovine tuberculosis in cattle herds and badgers in Ireland [PDF]

arXiv, 2020
Bovine tuberculosis, a disease that affects cattle and badgers in Ireland, was studied via stochastic epidemic modeling using incidence data from the Four Area Project (Griffin et al., 2005). The Four Area Project was a large scale field trial conducted in four diverse farming regions of Ireland over a five-year period (1997-2002) to evaluate the ...

Topological change and impedance spectrum of rat olfactory receptor I7: A comparative analysis with bovine rhodopsin and bacterior [PDF]

J. Appl. Phys. 105 084703 (2009), 2008
We present a theoretical investigation on possible selection of olfactory receptors (ORs) as sensing components of nanobiosensors. Accordingly, we generate the impedance spectra of the rat OR I7 in the native and activated state and analyze their differences. In this way, we connect the protein morphological transformation, caused by the sensing action,

Escherichia coli induces apoptosis and proliferation of mammary cells [PDF]

, 2001
Mammary cell apoptosis and proliferation were assessed after injection of Escherichia coli into the left mammary quarters of six cows. Bacteriological analysis of foremilk samples revealed coliform infection in the injected quarters of four cows.

Chronic pain management in a dairy cow with deep digital sepsis

Veterinary Record Case Reports, Volume 13, Issue 2, June 2025.
Abstract This case report describes a cow with a penetrating foreign body in the sole horn of its medial claw of the right forelimb, leading to sequestration and necrosis of the pedal bone and subsequent chronic pain. The surgical interventions, multimodal pain management and development of the gait pattern over more than 6 weeks are described. The cow

Virulence gene profiles: alpha-hemolysin and clonal diversity in Staphylococcus aureus isolates from bovine clinical mastitis in China

BMC Veterinary Research, 2018
Background Staphylococcus aureus, a common cause of bovine mastitis, is known for its ability to acquire to antimicrobial resistance and to secrete numerous virulence factors that can exacerbate inflammation. In addition, alpha-hemolysin has an important

Immunological responses against bovine viral diarrhoea virus types 1 and 2 after administration of a commercial subunit vaccine measured by ELISA and serum neutralisation on serum and milk samples

Veterinary Record Open, Volume 12, Issue 1, June 2025.
Abstract Background Our study evaluated the antibody responses against bovine viral diarrhoea virus (BVDV)‐1 and BVDV‐2 generated by a novel subunit vaccine comprising BVDV‐1 E2 and BVDV‐2 E2 recombinant glycoproteins. Methods Two trials were conducted.
