Samples (120) of ewes' raw milk collected over a 12-month period on arrival at the dairy and freshly drawn ewes' milk samples (30) collected at the farm were analysed for total viable counts and staphylococci. Total viable counts reached on the average 5.4 X 10(6)/ml in dairy samples and 6.0 X 10(5)/ml in farm samples, whereas mean levels of staphylococci were 5.9 X 10(4)/ml and 3.3 X 10(3)/ml, respectively. A high proportion (62%) of coagulase-positive isolates from Baird-Parker agar plates was detected in spring months. Staphylococcus aureus (42%), Staph. haemolyticus (23%) and Staph. epidermidis (10%) were the predominant species in 210 characterized isolates of staphylococci from ewes' raw milk. Seven coagulase-positive, maltose-negative staphylococci could not be identified with any of the recognized Staphylococcus species. Eighteen Micrococcus strains were identified as M. varians, whereas 111 Micrococcus strains of uncertain taxonomic status were separated into three groups, according to their physiological characters.
在12个月期间，对抵达乳品厂时收集的120份母羊生鲜乳样本以及在农场采集的30份刚挤出的母羊乳样本进行了总活菌数和葡萄球菌分析。乳品厂样本中的总活菌数平均达到5.4×10⁶/ml，农场样本中为6.0×10⁵/ml，而葡萄球菌的平均水平分别为5.9×10⁴/ml和3.3×10³/ml。在春季月份，从贝尔德-帕克琼脂平板上检测到的凝固酶阳性分离株比例很高（62%）。金黄色葡萄球菌（42%）、溶血葡萄球菌（23%）和表皮葡萄球菌（10%）是从母羊生鲜乳中分离出的210株葡萄球菌中的主要菌种。7株凝固酶阳性、麦芽糖阴性葡萄球菌无法用任何公认的葡萄球菌菌种进行鉴定。18株微球菌菌株被鉴定为变异微球菌，而111株分类地位不确定的微球菌菌株根据其生理特征分为三组。
