Intramammary antibiotic treatment at the end of lactation for prophylaxis and treatment of intramammary infections in ewes

Journal of the American Veterinary Medical Association, 1989
Summary Ewes treated by intramammary infusion of cephapirin benzathine at the end of lactation were less likely to develop new intramammary infections by early in the next lactation. A controlled clinical trial involving 135 treated ewes and 145 untreated control ewes evaluated the prophylactic and treatment efficacy of intramammary antibiotic ...

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.

Prevalence and Effects of Intramammary Infection in Beef Cows

Journal of Animal Science, 1986
Prevalence and effects of intramammary infection in 322 beef cows was determined during three calving intervals. Intramammary infection was confirmed in 37% of cows and 18.1% of quarters. Coagulase-positive staphylococci accounted for 17.9% of infections with Staphylococcus aureus isolated from 7.1% of cows.

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 ...

Patterns of nonclinical intramammary infection in a ewe flock

Journal of the American Veterinary Medical Association, 1986
SUMMARY Coagulase-negative staphylococci were the most frequent bacterial isolates from nonclinical intramammary infections (nimi) in a ewe flock. The prevalence of nimi was 22.9 % of the udder halves at lambing and decreased to 12.5% or less between week 2 and week 6 of lactation.

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.

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.
