De ouderdom van de tepelvoering als risicofactor voor de potentiële overdracht van Staphylococcus aureus

Abstract

A questionnaire was conducted to study the farmers’ behaviour concerning the replacement of teat-cup liners. Most of the questioned farmers replaced the teat-cup liners well past the recommended 2,500 milkings. Two in vitro experiments were used to investigate the role of teat-cup liner age in the possible transmission of Staphylococcus aureus. Teat-cup liners were contaminated with milk, from a cow known to be a Staph. aureus carrier. A teat-cup liner juice method was used to sample the teat-cup liners after contamination, the number of colony forming units (CFU) Staph. aureus / ml was defined. Three sets teat-cup liners of different ages were used in the experiments. No significant association was found between teat-cup liner age and Staph. aureus concentration in the samples.
