This investigation reported for the first time the occurrence of intramammary infections caused by Staphylococcus in primiparous replacement goats before parturition and the persistence of clinical Staphylococcus aureus infection during the lactation period. Subclinical infections, mainly caused by coagulase negative staphylococci (CoNS), did not persist during lactation. Genotyping analysis indicated that environment seems to play a moderate role as source of intramammary infections to goats before parturition, but causative agents of mastitis in lactating animals are not genotypically related to environmental staphylococci. The occurrence and persistence of intramammary infections in replacement goats demonstrate the need to consider those animals as potential sources of infections in dairy goat herds.
本研究首次报告了初产代孕山羊在分娩前发生由葡萄球菌引起的乳房内感染，以及金黄色葡萄球菌临床感染在泌乳期的持续情况。主要由凝固酶阴性葡萄球菌（CoNS）引起的亚临床感染在泌乳期未持续存在。基因分型分析表明，环境似乎在分娩前山羊乳房内感染源方面发挥了一定作用，但泌乳期动物乳腺炎的病原体在基因型上与环境葡萄球菌无关。代孕山羊乳房内感染的发生和持续表明，有必要将这些动物视为奶山羊群中潜在的感染源。
