The sheep is becoming increasingly used as a large animal model for preclinical spine surgery studies. Access to the ovine lumbar intervertebral discs has traditionally been via an anterior or anterolateral approach, which requires larger wound incisions and, at times, significant abdominal retraction. We present a new minimally invasive operative technique for a far-lateral approach to the ovi...

A cell line (designated BMpXT1) was generated from sheep bone marrow using the Moloney murine leukemia virus-based retroviral vector pXT1. BMpXT1 cells resembled mature alveolar macrophages in being adherent and esterase positive, in expressing certain cell surface antigens, and in secreting granulocyte-macrophage colony-stimulating factor (GM-CSF) when stimulated by ovine interferon-gamma and ...

Toxoplasma gondii DNA was detected at rates of 2%, 6%, 4.17%, 20%, and 19% in 50 bovine brains, 50 bovine muscles, 120 ovine brains, 20 ovine muscles, and in 100 fermented sausage samples, respectively. Sequenced positive samples showed 100% identity with T. gondii RH strain. Seropositivity rates were detected as 24% in cattle and 25% in sheep slaughtered in local slaughterhouses. The detection...

This paper examines morbidity and mortality patterns in interwar England and Wales, using previously under-explored primary archival source materials. These materials help us understand not only what local authorities could and did do, but also the reasons for the marked variations in the ability of different authorities to manage the problem. We identify where and why there were problems and a...

BACKGROUND The aim of this study was to investigate possible cross-infection of Dichelobacter nodosus in Norwegian farms practising co-grazing of sheep and cattle. METHODS Thirteen farms practising co-grazing of sheep and cattle were included in this descriptive study: five farms with a history of severe ovine footrot (Group I) and eight farms with free-stall housing of cattle and signs of mi...
