Fecal non-aureus Staphylococci are a potential cause of bovine intramammary infection [PDF]

Veterinary Research, 2020
The presence of non-aureus staphylococci (NAS) in bovine rectal feces has recently been described. Similar to other mastitis causing pathogens, shedding of NAS in the environment could result in intramammary infection.

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 ...

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 conducted to evaluate literature estimates of the cost and cost-benefits of mastitis control.

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 ...
