该协议概述了获得无菌(GF)鱼胚胎并将其从幼虫维持到幼虫阶段的主要步骤,包括取样和检测其不育状态。使用GF模型处理感染对于理解微生物在宿主健康中的作用非常重要。

这项研究的范围是生成新颖的、无菌的动物模型,这将是研究各种微生物组功能的有用和强大的工具。在该领域,早期的无菌鱼模型是最近才得到应用的,但由于养殖条件和工作人员发育防御的不同,长期模型仍然有限。目前的GF鱼模型通常是早期生命的。

因此,包括无菌秤、样品检测方法和提供无菌食品在内的技术是需要克服的非常重要的挑战。无菌斑马鱼模型对于研究宿主-微生物群相互作用及其对发育、免疫和疾病的影响至关重要。该模型使研究人员能够精确地操纵单个肠道细菌,并观察其对透明斑马鱼胚胎的影响。
