To determine the prevalence and causes of subclinical caprine mastitis, an investigation based on bacteriological diagnosis was carried out in three dairy herds (A, B and C) respectively constituted of Saanen, Alpine and a local breed, Draa. Among 287 samples analysed in the study 98 teats (34%) were infected. Coagulase-negative Staphylococci were the most frequently isolated (43% of total isolated bacteria) followed by Bacillus spp. (27%) and Staphylococcus aureus (13%). Other bacteria isolated were Pseudomonas spp. (6%), Streptococcus spp. and coliforms (5%) and Micrococcus spp. (2%). No Mycoplasma was recovered. The epidemiologic study showed the significant effect of the type of herd husbandry and breed as well as the number and month of lactation.
为确定亚临床型山羊乳腺炎的患病率及病因，分别对由萨能山羊、阿尔卑斯山羊和当地品种德拉山羊组成的三个奶牛群（A、B和C）进行了基于细菌学诊断的调查。在该研究分析的287份样本中，98个乳头（34%）受到感染。凝固酶阴性葡萄球菌是最常分离出的细菌（占分离出细菌总数的43%），其次是芽孢杆菌属（27%）和金黄色葡萄球菌（13%）。分离出的其他细菌有假单胞菌属（6%）、链球菌属和大肠菌群（5%）以及微球菌属（2%）。未分离到支原体。流行病学研究表明，饲养方式、品种类型以及泌乳次数和月份有显著影响。
