N-Acetyl-β-D-Glucosaminidase Analysis in Sheep Milk Can Detect Early Intramammary Infection with High Yields If Incorporated into Mathematical Algorithms [PDF]
AnimalsThe aim of this study was to analyse the effect of intramammary infection (IMI) on N-acetyl-β-D-glucosaminidase (NAGase) enzyme values and to study its predictive capacity using different algorithms.

BMC Veterinary Research, 2011 Background Staphylococcus aureus is one of the most prevalent pathogens to cause mastitis in dairy cattle. Intramammary infection of dairy cows with S. aureus is often subclinical, due to the pathogen's ability to evade the innate defense mechanisms, but

The Effect of an Intramammary Teat Seal on New Intramammary Infections [PDF]
Journal of Dairy Science, 2002 As concern over the possible overuse of antibacterials increases, attention has focused on reduction of antibiotic usage and on nonantibiotic alternatives. A nonantibiotic intramammary teat sealant, Teat Seal (Cross Vetpharm Group Ltd., Tallaght, Dublin, Ireland), has been available in Ireland, in combination with an intramammary tube of cloxacillin ...

Detecting intramammary infection at the end of lactation in dairy cows
Journal of Dairy Science, 2021 To reduce antimicrobial use, infusion of antimicrobials into only infected cows at the end of lactation (selective dry cow therapy) is preferable to infusion of every cow with antimicrobials. Use of selective dry cow antimicrobial therapy requires differentiation of probably infected from uninfected cows to enable treatment allocation.

Bio-economic modeling of bovine intramammary infections
, 2009 The research of this thesis was directed to support decision making in relation to mastitis control with special focus on the dry period. First, a guideline to cost factors associated with mastitis was set, and a comprehensive literature review was ...

Innate immune response to intramammary Mycoplasma bovis infection [PDF]
Journal of Dairy Science, 2007 The objective of the current study was to characterize the systemic and local innate immune response of dairy cows to IMI with Mycoplasma bovis, a pathogen of growing concern to the dairy industry. Ten Holstein cows were each infused in 1 quarter with M.

Dynamics and Significance of Coagulase-Negative Staphylococcal Intramammary Infections
Journal of Dairy Science, 1987 Cows (n = 139) were sampled within 17 d postpartum and monthly thereafter to examine dynamics of mammary infections and relationships between infection status, milk yield, SCC, NAGase activity, and chloride concentration. Forty-eight and 67% of cows and 19.5 and 30.5% of quarters were infected at first test and lactation end, respectively, with 51% of ...
