title: Sampling of the bovine teat for studies of defence mechanisms and inflammatory reactions based on a surgical procedure separating the teat and udder cisterns.
abstract: A surgical procedure to separate the teat and udder cisterns in the udder quarter was described. The sampling method used and its influence on the somatic cell count and bacteriological status of the teat samples were determined. The surgical procedure resulted in complete separation of the teat cistern from the udder cistern in nine out of fourteen teats in six cows. An increase in SCC was seen in one of nine teats during the sampling period of 4 to 8 days. Coagulase-negative staphylococci were isolated in samples from three of six teats at the end of the sampling period. The described methods could be of considerable importance in future studies of inflammatory reactions and defence mechanisms in the bovine teat.
