Cockatiels () were originally endemic to Australia; now they are popular pets with a global distribution. It is now possible to conduct detailed molecular studies on cultivable and uncultivable bacteria that are part of the intestinal microbiome of healthy animals. These studies show that bacteria are an essential part of the metabolic capacity of animals. There are few studies on bird microbiomes and, to the best of our knowledge, this is the first report on the cockatiel microbiome.
In this paper, we analyzed the gut microbiome from fecal samples of three healthy adult cockatiels by massive sequencing of the 16S rRNA gene. Additionally, we compared the cockatiel fecal microbiomes with those of other bird species, including poultry and wild birds.
The vast majority of the bacteria found in cockatiels were , while and were poorly represented. A total of 19,280 different OTUs were detected, of which 8,072 belonged to the family.
It is relevant to study cockatiel the microbiomes of cockatiels owing to their wide geographic distribution and close human contact. This study serves as a reference for cockatiel bacterial diversity. Despite the large OTU numbers, the diversity is not even and is dominated by of the family. Cockatiels and other wild birds are almost depleted of , which happen to be abundant in poultry-related birds, and this is probably associated with the intensive human manipulation of poultry bird diets. Some probable pathogenic bacteria, such as and appeared to be frequent inhabitants of the fecal microbiome of cockatiels, whereas other potential pathogens were not detected.
鸡尾鹦鹉最初原产于澳大利亚；现在它们是全球分布的受欢迎宠物。现在有可能对健康动物肠道微生物群中可培养和不可培养的细菌进行详细的分子研究。这些研究表明，细菌是动物代谢能力的重要组成部分。关于鸟类微生物群的研究很少，据我们所知，这是第一份关于鸡尾鹦鹉微生物群的报告。
在本文中，我们通过对16S rRNA基因进行大规模测序，分析了三只健康成年鸡尾鹦鹉粪便样本中的肠道微生物群。此外，我们将鸡尾鹦鹉的粪便微生物群与其他鸟类物种（包括家禽和野生鸟类）的进行了比较。
在鸡尾鹦鹉中发现的绝大多数细菌是[具体细菌名称未给出]，而[另外两种细菌名称未给出]的占比很低。总共检测到19280个不同的操作分类单元（OTU），其中8072个属于[具体细菌家族名称未给出]家族。
由于鸡尾鹦鹉广泛的地理分布和与人类的密切接触，研究其微生物群具有重要意义。这项研究为鸡尾鹦鹉的细菌多样性提供了参考。尽管OTU数量很多，但多样性并不均匀，以[具体细菌家族名称未给出]家族的[具体细菌名称未给出]为主导。鸡尾鹦鹉和其他野生鸟类几乎没有[某种细菌名称未给出]，而这种细菌在家禽相关鸟类中很丰富，这可能与人类对家禽饮食的密集操控有关。一些可能的致病细菌，如[具体细菌名称未给出]和[具体细菌名称未给出]似乎是鸡尾鹦鹉粪便微生物群中的常见居民，而其他潜在病原体未被检测到。
