The ostrich () is an herbivorous bird with a long and developed hindgut. In the hindgut, there is a dense and highly diverse population of anaerobic bacteria, and active fermentation produces high concentrations of short-chain fatty acids. Bacteria in the hindgut of the ostrich are considered vital for both their nutritional contribution and health benefits, such as benefits to the immune and defense system of the host. We attempted to isolate , which might be involved in improving immune function and in inhibiting pathogens. The number of colonies from ostrich feces observed on LBS agar medium was 3.64×10 per gram of feces. Three strains of were isolated from the feces. Nearly the entire length of the 16S ribosomal RNA gene of these isolates was sequenced, and a homology search showed high identity with (identity=99.93%), (98.39%), and (100.0%). These isolates may be deemed potential probiotics for the ostrich.
鸵鸟是一种食草鸟类，其后肠长且发达。在后肠中，存在大量密集且高度多样的厌氧细菌，活跃的发酵过程会产生高浓度的短链脂肪酸。鸵鸟后肠中的细菌被认为对其营养贡献和健康益处至关重要，比如对宿主免疫和防御系统有益。我们试图分离出可能参与改善免疫功能和抑制病原体的[具体细菌名称未给出]。在LBS琼脂培养基上观察到每克鸵鸟粪便中菌落数为3.64×10[次方未给出]。从粪便中分离出了三株[具体细菌名称未给出]。对这些分离株的16S核糖体RNA基因几乎全长进行了测序，同源性搜索显示与[具体细菌名称未给出1]（同一性=99.93%）、[具体细菌名称未给出2]（98.39%）和[具体细菌名称未给出3]（100.0%）具有高度同一性。这些分离株可被视为鸵鸟的潜在益生菌。
