Diagnosis and characteristics of contagious mastitis caused by Staphylococcus aureus and Streptococcus agalactiae
With rapidly increasing herd sizes, focus on contagious udder pathogens becomes important. Based on a yearly test of bulk tank milk in Danish dairy herds, the prevalence of herds infected with Streptococcus agalactiae (S. agalactiae) increased from 2 % in 2000 to 7 % in 2010, while approximately 90 % of the herds were positive for Staphylococcus aureus (S. aureus) (Katholm, et al., 2012). The r...
متن کاملEfficacy 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...
متن کاملAssociation between teat skin colonization and intramammary infections with Staphylococcus aureus and Streptococcus agalactiae
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 cr...
متن کاملFactors associated with intramammary infection in dairy cows caused by coagulase-negative staphylococci, Staphylococcus aureus, Streptococcus uberis, Streptococcus dysgalactiae, Corynebacterium bovis, or Escherichia coli.
The aim of this study was to determine risk factors for bovine intramammary infection (IMI) associated with the most common bacterial species in Finland. Large databases of the Finnish milk-recording system and results of microbiological analyses of mastitic milk samples from Valio Ltd. (Helsinki, Finland) were analyzed. The study group comprised 29,969 cows with IMI from 4,173 dairy herds. A c...
متن کاملQuarter milk somatic cell count in infected dairy cows: a meta-analysis.
The aim of this paper was to evaluate the effects associated with intramammary infection (IMI) by a bacterium or a group of bacteria (Staphylococcus aureus, Streptococcus agalactiae, Streptococcus dysgalactiae, Streptococcus uberis, coliforms, Staphylococci other than S. aureus, and Corynebacterium bovis) on the somatic cell count (SCC) in quarter milk of dairy cows. Papers selected for analysi...
