Abstract

Milk samples (n = 160) from 7 clinically healthy bactrian camels were cultured to detect subclinical udder infection. The samples were assessed by the Californian mastitis test (CMT) and somatic cell count (SCC). Bacteria were recovered from 36 (22.5%) of the milk samples. Staphylococcus aureus and coagulase-negative staphylococci (CNS) were the main organisms found. Infected quarters had significantly higher mean values for the SCC (p < 0.01) and CMT (p < 0.001) than non-infected quarters. All 7 camels were infected with CNS but only 4 with S. aureus. CMT values for S. aureus-infected camels were significantly higher than for those only infected with CNS. The values for SCC and CMT were significantly influenced by the stage of lactation (p < 0.05). No significant difference was found from the effect of the quarters. Both SCC and CMT were of value in predicting the infection status of the udder.

摘要

对7头临床健康双峰驼的160份乳样进行培养，以检测亚临床型乳房感染。通过加利福尼亚乳房炎试验（CMT）和体细胞计数（SCC）对这些样本进行评估。从36份（22.5%）乳样中分离出细菌。金黄色葡萄球菌和凝固酶阴性葡萄球菌（CNS）是主要分离出的微生物。感染乳区的SCC（p < 0.01）和CMT（p < 0.001）平均值显著高于未感染乳区。所有7头骆驼均感染了CNS，但仅4头感染了金黄色葡萄球菌。感染金黄色葡萄球菌的骆驼的CMT值显著高于仅感染CNS的骆驼。SCC和CMT值受泌乳阶段的显著影响（p < 0.05）。未发现不同乳区之间存在显著差异。SCC和CMT在预测乳房感染状况方面均有价值。
