Abstract

Staphylococcus aureus is the most important gram-positive bacteria causing bovine mastitis. In Engaru-cho, Hokkaido, Japan, the increase of S. aureus mastitis was subjectively observed in 2005 after the introduction of anonymous post-milking dipping Iodine-based product A. The present study was conducted to investigate the association between this product and the incidence of S. aureus mastitis.<BR>Nine farms which experienced S. aureus mastitis were selected and the data stored in Okhotsk Agriculture Mutual Association on the diagnoses with S. aureus mastitis and husbandry practice between April 2005 and March 2007 were used for the analysis. Generalized Estimating Equations (GEE) were performed to examine the association between teat level incidence rate of S. aureus mastitis and farming style, types of pre milking teat disinfectants and post milking teat dip products. A stochastic decision tree analysis was performed for economic analysis.<BR>The use of post-milking teat dip product A was a single risk factor ; the adjusted annual incidence rate was 3.0% (95%CI : 1.5%—5.8%) while that of product B 1.1% (95%CI : 0.6%—2.2%, p=0.042). Although the price of the product B was 1.5 times more expensive than A, the annual cost controlling S. aureus mastitis per teat using the product B was cheaper (JPY 837, 95%CI : 681—1,134) than that of product A (JPY 1,212, 95%CI : 796—2,020).<BR>The degradation of teat skin caused by the lower pH and glycerol concentration of the product A might be the cause of the elevated incidence. The use of Epidemiological and economic analyses were proved to be useful in evidence-based veterinary medicine.
