Association between teat skin colonization and intramammary infections with Staphylococcus aureus and Streptococcus agalactiae

چکیده
Introduction and Objective Staphylococcus aureus and Streptococcus agalactiae are traditionally considered contagious mastitis pathogens mainly causing subclinical infections in dairy cattle. The consequences of subclinical mastitis are economic losses to the farmer and impaired milk quality. To improve the control of contagious mastitis pathogens, knowledge of reservoirs and transmission is crucial. The role of the teat skin as a reservoir of Strep. agalactiae is unknown and still discussed for Staph. aureus. Furthermore, teat skin colonization is not yet investigated in automatic milking systems (AMS) with more milkings per cow and less human contact compared with conventional milking. Thus, the objective of this study was to investigate the association of teat skin colonization with intramammary infections for Staph. aureus or Strep. agalactiae in herds with AMS.

Efficacy of two hydrogen peroxide teat disinfectants against Staphylococcus aureus and Streptococcus agalactiae.
An experimental teat dip containing 0.5% hydrogen peroxide as the active ingredient was compared with a teat disinfectant also containing 0.5% hydrogen peroxide that is commercially available throughout North America. The study was conducted under conditions of experimental challenge with a positive control following the guidelines recommended by the National Mastitis Council. The efficacy of t...

The effectiveness of a teat dip with dodecyl benzene sulfonic acid (1.94%) for the prevention of intramammary infections was determined in cows experimentally challenged with Streptococcus agalactiae and Staphylococcus aureus. The infection rates with Streptococcus agalactiae and Staphylococcus aureus were 62.5% and 75% in undipped quarters, 12.5% and 21.5% in dipped quarters with a reduction r...
متن کاملEffects of an automatic postmilking teat dipping system on new intramammary infections and iodine in milk.
A technology of automatically applying a postmilking teat dip via the milking machine prior to machine detachment was compared to manual postmilking teat dipping with a teat dip cup for effects on new IMI and iodine content in milk. One hundred twenty Holstein cows were experimentally challenged in a 22-wk trial with Streptococcus agalactiae and Staphylococcus aureus and 148 Holstein cows were ...
متن کاملHost adapted intramammary infections in pregnant heifers which were co-housed and reared on fresh milk as calves
BACKGROUND Heifers can calve down with intramammary infections (IMI) and udder damage. This will have a negative impact on their longevity, future milk yield and financial return. Co-housed pre-weaned calves that are fed fresh milk have the opportunity to suckle each other's teats and may infect udders of fellow heifer calves with pathogens present in milk. The prevalence of IMI in pregnant hei...

Mastitis in dry cows has traditionally been controlled with long-acting intramammary antibiotic formulations. However, the widespread use of antibiotics, particularly for prophylactic application, is likely to be restricted in the future. As a consequence, there is now a growing requirement for effective alternatives to prevent mastitis. A bismuth-based, intramammary teat seal has recently been...
