Neutrophil apoptosis during experimentally induced Staphylococcus aureus mastitis.
The objective of this study was to determine whether neutrophil apoptosis and their consequent elimination by macrophages from the mammary gland is modulated by an infection caused by Staphylococcus aureus (S. aureus). The study was performed on twenty mammary glands of 5 virgin heifers. A buffered physiological solution (PBS) was administered as a means of control into the mammary glands of th...
متن کاملMastitis Prevention and Cure Rates in Heifers Treated with Spectramast Dry Cow Therapy and/or Orbeseal Dry Cow Teat Sealant
Dairy cows are vital for milk production, cheese, cream, and so much more. Healthy udders and teats are necessary to keep production levels at their highest and to keep the number of cows being culled to the lowest levels. Inflammation of the mammary gland is called mastitis, which is typically caused by bacteria that invade the teat canal. This disease is most often transmitted by contact with...
متن کاملUse of Dry Cow Therapy and Teat Seal in Managing Mastitis in Bred Holstein Heifers
Because of the importance of bred heifers to the future milk production of any dairy operation, it is critical that udder health be maximized to ensure that animals freshen free of intramammary infection (IMI). During the heifer’s first gestation, the presence of mastitis can compromise the development of milk-producing tissues, and in the case of Staphylococcus aureus, milk yield may be reduce...
متن کاملPrevalence of mastitis in dairy heifers and effectiveness of antibiotic therapy.
Dairy heifers were treated 0 to 90 d, 90 to 180 d, or 180 to 270 d prepartum with one of five different antibiotic products to determine the best time and with which product they should be treated prior to calving. Two hundred thirty-three heifers were included in the study. At the initial sampling, 56.5% of quarters were infected with some type of organism and 15.4% of quarters were infected w...
متن کاملLoop-Mediated Isothermal Amplification for Detection of Staphylococcus aureus in Dairy Cow Suffering from Mastitis
To develop a rapid detection method of Staphylococcus aureus using loop-mediated isothermal amplification (LAMP), four specific primers were designed according to six distinct sequences of the nuc gene. In addition, the specificity and sensitivity of LAMP were verified and compared with those of PCR. Results showed that the LAMP reaction was completed within 45 min at 62.5°C, and ladder bands w...
