Mastitis, an inflammation of the mammary gland most often resulting from a bacterial infection, is a multi-faceted disease and is one of the most expensive dairy cow health problems. The estimated cost of mastitis for Canadian dairy producers is approximately $300 million per year. Mastitis reduces milk yield of dairy cows and affects animal welfare with clearly visible and measurable signs of sickness and discomfort. Furthermore, antibiotics treatments used to treat and prevent mastitis represent a very large proportion of the antibiotics used on Canadian dairies and constitute a risk of residues in the milk supply that could be a threat for public health. Finally, there is currently no gold standard test to diagnose intramammary infections (IMI) and this later aspect has important repercussions both in research and in practice.

乳腺炎是一种最常见的由细菌感染引起的乳腺炎症，是一种多方面的疾病，是最昂贵的奶牛健康问题之一。据估计，加拿大乳制品生产商每年的乳腺炎费用约为3亿美元。乳腺炎降低奶牛的产奶量，并影响动物福利，具有清晰可见和可测量的疾病和不适症状。此外，用于治疗和预防乳腺炎的抗生素治疗在加拿大奶牛场使用的抗生素中占很大比例，并构成牛奶供应中残留的风险，可能对公共健康构成威胁。最后，目前还没有诊断乳房内感染（IMI）的金标准测试，后者在研究和实践中都有重要影响。
