Genetically enhanced cows resist intramammary Staphylococcus aureus infection

Nature Biotechnology, 2005
Mastitis, the most consequential disease in dairy cattle, costs the US dairy industry billions of dollars annually. To test the feasibility of protecting animals through genetic engineering, transgenic cows secreting lysostaphin at concentrations ranging from 0.9 to 14 micrograms/ml [corrected] in their milk were produced.

Streptococci Isolated from Bovine Intramammary Infections

American Journal of Veterinary Research, 1976
SUMMARY Streptococcal isolates from 71 dairy herds considered free of Streptococcus agalactiae were compared with isolates from 1 herd used in bovine mastitis research over a 12-year period. The incidence of streptococci was as follows: Streptococcus uberis, 56.5%; enterococci, 24.2%; Streptococcus dysgalactiae, 9.0%; Streptococcus bovis, 5.1 ...

Prevalence of intramammary infection in Dutch dairy herds

Journal of Dairy Research, 2009
A survey was carried out in 2003 in 49 dairy herds to determine the overall and pathogen-specific prevalence of intramammary infection (IMI) in Dutch dairy herds, and to compare the distribution with four studies performed from 1973 to 1985 in The Netherlands.

Antibiograms of Streptococci Isolated from Bovine Intramammary Infections

American Journal of Veterinary Research, 1976
SUMMARY A total of 455 streptococcal cultures from bovine intramammary infection in 72 herds were studied to determine their sensitivity to 17 antimicrobial agents. More than 90% of the cultures were sensitive to carbenicillin, chloramphenicol, erythromycin, and penicillin.

Effect of intramammary infusion of bacterial lipopolysaccharide on experimentally induced Staphylococcus aureus intramammary infection

Research in Veterinary Science, 2007
Mastitis due to Staphylococcus aureus is a significant problem in the dairy industry and is refractory to antibiotic treatment and/or vaccine prevention. Relative to other mastitis-causing pathogens, S. aureus elicits a diminutive host inflammatory response during intramammary infection.

The Pathogenic Significance of Various Intramammary Infections

British Veterinary Journal, 1970
SUMMARY The presence of intramammary infections in all quarters of eighteen cows was determined by collecting milk samples by syringe from the teat sinus through the teat wall. The samples were taken within 1 week before calving, 8 weeks after calving and thereafter at monthly intervals throughout lactation.
