Demodex folliculorum and D. brevis are cosmopolitan, obligatory parasites. Epidemiological studies have established a clear association between these species and various facial diseases in humans. However, not much is known of the ecology of these mites, also because it has proven difficult to culture them. Here we report a laboratory study on the (combined) effects of temperature and culture medium on the viability of both species. Results showed significant differences in the survival time of D. folliculorum and D. brevis among different temperatures and media. Pair-wise comparisons revealed that both species survived longest in serum medium, at a temperature of 16-22 °C. Therefore, we conclude that these conditions allow preservation and maintenance of both Demodex mites.
毛囊蠕形螨和短须螨是世界性的、专性寄生虫。流行病学研究已经确定了这些物种与人类各种面部疾病之间的明确关联。然而，人们对这些螨虫的生态学了解甚少，这也是因为它们的培养证明很困难。在这里，我们报告了一项关于温度和培养基对两种螨类生存能力（联合）影响的实验室研究。结果表明，在不同温度和培养基中，毛囊蠕形螨和短须螨的存活时间有显著差异。成对比较显示，两种螨在血清培养基中、温度为 16-22°C 时存活时间最长。因此，我们得出结论，这些条件允许两种蠕形螨的保存和维持。
