Therapeutic Efficacy of Mammary Irrigation Regimen in Dairy Cattle Diagnosed with Acute Coliform Mastitis

Therapeutic efficacy of mammary irrigation regimen in dairy cattle diagnosed with acute coliform mastitis.

The objective of this field study was to determine the therapeutic efficacy of mammary irrigation for the treatment of dairy cattle diagnosed with acute coliform mastitis caused by gram-negative bacteria. Additionally, the effects of different mammary irrigation regimen fluids such as ozone water and normal saline were compared. Dairy cattle clinically diagnosed with acute coliform mastitis (n ...

15‐F2t‐Isoprostane Concentrations and Oxidant Status in Lactating Dairy Cattle with Acute Coliform Mastitis

BACKGROUND Severe mammary tissue damage during acute coliform mastitis in cattle is partially caused by oxidative stress. Although considered a gold standard biomarker in some human conditions, the utility of 15-F2t-Isoprostanes (15-F2t-Isop) in detecting oxidative stress in dairy cattle has not been validated. HYPOTHESIS Concentrations of 15-F2t-Isop in plasma, urine, and milk correlate with...

Comparison of disease severity scoring systems for dairy cattle with acute coliform mastitis.

OBJECTIVE To compare use of 4 disease severity scoring systems to predict bacteremia (yes vs no) and outcome (survived vs died or culled) in dairy cows with acute coliform mastitis (ACM). DESIGN Retrospective cohort study. ANIMALS 99 dairy cows with ACM. PROCEDURES Cows were classified as having mild, moderate, or severe disease with a scoring system based on systemic disease signs alone ...

Mycoplasma Mastitis in Dairy Cattle

Expression profile of genes associated with mastitis in dairy cattle

In order to characterize the expression of genes associated with immune response mechanisms to mastitis, we quantified the relative expression of the IL-2, IL-4, IL-6, IL-8, IL-10, IFN-γ and TNF- α genes in milk cells of healthy cows and cows with clinical mastitis. Total RNA was extracted from milk cells of six Black and White Holstein (BW) cows and six Gyr cows, including three animals with a...
