Summary
The avian gut microbiota composition is similar to mammals. Host bird species is the primary factor shaping gut microbes, with diet and environment also playing roles.
Area of Science:
- Microbiology
- Zoology
- Bioinformatics
Background:
- Avian species host diverse gut microorganisms crucial for nutrition and pathogen defense.
- Previous studies focused on specific microbes, lacking a holistic view of avian gut microbiota factors.
Purpose of the Study:
- To conduct the first meta-analysis of avian gut microbiota using sequence-based data.
- To identify key factors influencing avian gut microbial community structure and membership.
Main Methods:
- Meta-analysis of 16S rRNA gene sequences from public databases (clone-library and amplicon pyrosequencing data).
- Investigation of host phylogeny, gut location, diet, and human association as influencing factors.
Main Results:
- Avian gut microbiota exhibits phylum-level composition similar to mammals.
- Host bird species is the most significant determinant of microbial community composition.
- Sampling site, diet, and captivity status also influence the gut microbiota.
Conclusions:
- This meta-analysis provides an integrated overview of avian gut microbiota composition.
- Host phylogeny is a key driver, but environmental and dietary factors are also important.
- Establishes a foundation for future research on avian gut microbiome.

01:18Functions of the Gut Microbiota
222
The gut microbiota includes trillions of microorganisms that colonize the human gastrointestinal tract, including bacteria, archaea, viruses, and fungi. This complex ecosystem plays a critical role in maintaining intestinal and systemic health. Most of these microbes inhabit the large intestine, establishing a relatively stable and diverse community that contributes to gut homeostasis through various metabolic, immunological, and protective mechanisms.Dominant bacterial phyla, such as...

01:27Microbiota of the Large Intestine
96
The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...

01:22Introduction to the Human Microbiota
199
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity,...

01:22Gut-Brain Axis
216
The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such...

01:27Microbiota of the Stomach and Small Intestine
75
The human gastrointestinal (GI) tract is characterized by distinct physicochemical conditions that shape its microbial communities. Among these, the stomach presents a particularly challenging environment for microbial colonization due to its highly acidic pH, ranging from 1 to 3. This extreme acidity effectively limits microbial density. However, certain acid-tolerant microorganisms are capable of surviving in this niche. Notably, Helicobacter pylori can colonize the gastric mucosa,...

01:30Development of Human Microbiota
61
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...
