As part of a health investigation on koalas at San Diego Zoo, serum samples were analyzed from 18 free-ranging and 22 zoo-based koalas, Phascolarctos cinereus. Serum concentrations of calcium, chloride, cobalt, copper, iron, magnesium, manganese, molybdenum, phosphorus, potassium, selenium, sodium, zinc, and vitamins A, E, and 25(OH)D3 were quantified. Calcium, chloride, molybdenum, selenium, and vitamin E concentrations were significantly higher in zoo-based koalas than in free-ranging koalas, whereas magnesium, manganese, phosphorus, and zinc concentrations were significantly higher in the free-ranging koalas. No significant differences were found between genders. The results from this study will help to establish a starting point for determining target circulating nutrient concentrations in koalas.
作为圣地亚哥动物园对考拉进行健康调查的一部分，对18只野生考拉和22只圈养在动物园里的考拉（树袋熊）的血清样本进行了分析。对血清中的钙、氯、钴、铜、铁、镁、锰、钼、磷、钾、硒、钠、锌以及维生素A、E和25(OH)D3的浓度进行了定量分析。圈养考拉的钙、氯、钼、硒和维生素E浓度显著高于野生考拉，而野生考拉的镁、锰、磷和锌浓度显著更高。未发现性别之间存在显著差异。这项研究的结果将有助于为确定考拉血液中营养物质的目标浓度建立一个起点。
