Analysis of 448 milk samples (11 herds) from caprine udder halves showed that microorganisms were isolated from 21.8% of the samples. California Mastitis Test (CMT) and N-acetyl-beta-glucosaminidase (NAGase) were superior to antitrypsin in detecting subclinical infections. Coagulase-negative staphylococci and micrococci were the main species isolated from halves showing no clinical disease. Coagulase-positive staphylococcal infections were associated with a significant increase of all inflammatory parameters. Significantly increased CMT and NAGase occurred when streptococci, other staphylococci or micrococci were present. Infection within one half was reflected as an increase in the inflammatory parameters in the milk of the infected half as well as a slight increase in the inflammation parameters in the adjoining half.
对来自11个羊群的448份山羊乳房半侧的乳样进行分析，结果显示21.8%的样本中分离出了微生物。加利福尼亚乳房炎检测法（CMT）和N-乙酰-β-葡萄糖苷酶（NAGase）在检测亚临床感染方面优于抗胰蛋白酶。凝固酶阴性葡萄球菌和微球菌是从无临床疾病的乳房半侧分离出的主要菌种。凝固酶阳性葡萄球菌感染与所有炎症参数的显著增加有关。当存在链球菌、其他葡萄球菌或微球菌时，CMT和NAGase显著升高。一侧乳房的感染表现为感染侧乳汁中炎症参数增加，以及相邻一侧炎症参数略有增加。
