Summary
Beneficial enterococci offer probiotic and antimicrobial benefits for health and food systems. However, rigorous safety assessments are crucial due to their potential role in infections and antimicrobial resistance.
Area of Science:
- Microbiology
- Food Science
- Probiotics
Background:
- Enterococcus species are common commensal bacteria in humans and animals.
- Beneficial enterococci strains are used as probiotics, antibiotic alternatives, and protective cultures.
- They offer benefits in food fermentation, safety, and produce bioactive compounds like bacteriocins.
Purpose of the Study:
- To provide a comprehensive overview of the probiotic and antimicrobial potential of beneficial enterococci.
- To highlight the safety considerations associated with their use.
- To serve as a resource for research, regulatory assessment, and applications.
Main Methods:
- Literature review and synthesis of existing research on Enterococcus spp.
- Analysis of probiotic properties, antimicrobial activities, and safety data.
- Compilation of information on applications in health and agrifood systems.
Main Results:
- Enterococci possess significant probiotic and antimicrobial capabilities, including pathogen inhibition.
- They contribute to food safety, enhance sensory attributes, and produce health-promoting compounds.
- Concerns exist regarding their association with healthcare-associated infections and antimicrobial resistance.
Conclusions:
- Beneficial enterococci present multifaceted potential for health and agrifood applications.
- Stringent safety evaluations are essential before widespread use.
- Further research and regulatory oversight are needed to maximize benefits while mitigating risks.

01:22Probiotics
296
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...

01:27Microbiota of the Large Intestine
98
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...

01:25Clinical Significance of Antibiotic Resistance
90
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...

01:22Introduction to the Human Microbiota
209
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,...

53
The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...

Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...
