Antibiotics and the gut microbiota.
The Journal of Clinical Investigation
|October 2, 2014
Summary
Antibiotics disrupt the human gut microbiota, altering its diversity and function. Reconsidering antimicrobial therapies through an ecological lens is crucial for preserving beneficial gut bacteria.
Area of Science:
- Microbiology
- Ecology
- Pharmacology
Background:
- Antibiotics are vital in medicine, public health, and agriculture.
- Emerging evidence highlights the detrimental effects of antibiotics on host-associated microbial communities.
Purpose of the Study:
- To examine the impact of antibiotics on the human gut microbiota.
- To propose an ecological framework for understanding antibiotic-induced alterations and informing future therapeutic strategies.
Main Methods:
- Review of recent studies on antibiotic effects on gut microbiota.
- Analysis of changes in microbial taxonomy, genomics, and functional capacity.
- Consideration of ecological principles like competitive exclusion and gene flow.
Main Results:
- Antibiotics rapidly and sometimes persistently alter gut microbiota composition and function.
- Broad-spectrum antibiotics decrease bacterial diversity and shift specific taxa.
- Antibiotic use promotes antibiotic resistance and pathogen invasion by disrupting microbial niches.
Conclusions:
- Antibiotic-induced alterations represent a disruption of host-microbe mutualism.
- An ecological perspective is essential for developing antimicrobial strategies that balance infection treatment with microbiota preservation.
- Understanding gut ecological dynamics can guide the design of novel therapies to maintain beneficial microbial communities.

119
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...

01:22Introduction to the Human Microbiota
136
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,...

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within...

Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...

01:22Probiotics
279
Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...

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...
