The global rise of multidrug-resistant (MDR) enteric pathogens has created an urgent clinical and agricultural demand for natural antibiotic alternatives. While traditional probiotics like Lactobacillus and Bifidobacterium have paved the way, the scientific community is now shifting its focus toward Next-Generation Probiotics (NGPs). Recent breakthroughs, such as the isolation of robust, goat-derived Enterococcus strains, have demonstrated that the path to superior gut health and pathogen defense lies in mining diverse, non-conventional microbiotas.
At Creative Biolabs, we provide a comprehensive CRO platform designed to translate these high-impact findings into scalable therapeutic candidates. Whether you are targeting livestock health or human biotherapeutics, our integrated services match the rigorous methodologies seen in cutting-edge literature to ensure your candidates are robust, safe, and effective.
Case Study Insight: Robust Goat-Derived Enterococcus as NGP Candidates 1
Recent literature highlighted in Veterinary Sciences (MDPI) has shed light on the exceptional potential of Enterococcus isolates derived from the feces of healthy goats.1 This research is a blueprint for NGP development, showcasing how specific environmental pressures can yield "hardened" microbial candidates with unique traits:
-
Exceptional GI Robustness: The study identified five key isolates (E. faecium, E. faecalis, E. hirae, S. lutetiensis) that maintained survival rates of up to 89.05% in simulated gastric juice (pH 2.0) and survived high concentrations of bile salts.
-
Broad-Spectrum Antimicrobial Power: Beyond standard inhibition, these strains showed significant activity against formidable pathogens, including Methicillin-resistant Staphylococcus aureus (MRSA), E. coli, and Shigella flexneri.
-
Superior Adhesion & Colonization: High cell surface hydrophobicity (up to 93.85%) and auto-aggregation properties ensure these strains don't just pass through-they colonize.
Creative Biolabs has optimized our service pipeline to replicate and expand upon these research parameters, offering our clients the ability to discover similarly high-performing strains from any biological source.
Comprehensive CRO Services for Enterococcus & NGP Development
To match the technical excellence required for identifying "robust" isolates, we offer a modular suite of services that mirrors the workflow of professional microbiome research.
Just as the literature mined goat microbiota, we offer Targeted Microbial Isolation from diverse sources, including:
-
Animal feces (livestock, companion animals, wild species).
-
Human clinical samples (fecal, oral, vaginal).
-
Fermented food and environmental niches.
-
Service Highlight: Our "Screening of 50+ Isolate Batches" ensures that only the top 1% of performers move to the characterization phase.
Following the study's use of biochemical and molecular tools, we provide:
A probiotic is only useful if it survives the "acid bath" of the stomach. Our In Vitro Gut Simulation Platform tests:
-
Acid Tolerance: Survival at pH 2.0-3.0 over 3-5 hours.
-
Bile Salt Resistance: Stability in 0.3% to 1.5% porcine or bovine bile salts.
-
Intestinal Fluid Simulation: Real-time viability tracking in simulated pancreatic environments.
Advanced Antipathogenic & Functional Assays
We quantify the competitive edge of your strains through:
-
Co-Aggregation Assays: Measuring the physical binding of probiotics to pathogens like Salmonella and E. coli.
-
Pathogen Displacement Testing: In vitro models showing how probiotics "kick off" established pathogens from mucosal surfaces.
-
Bacteriocin Characterization: Identification and purification of the specific antimicrobial peptides produced by your strains.
Rigorous Safety Assessment for Live Biotherapeutic Products (LBPs)
The Enterococcus, while naturally occurring, requires stringent safety verification due to the risk of opportunistic pathogenicity. Creative Biolabs provides the necessary data for regulatory filings
-
Hemolytic Activity Screening: Ensuring isolates are non-hemolytic (γ-hemolysis).
-
Antibiotic Susceptibility Testing (AST): Utilizing the Disk Diffusion and MIC methods to ensure no resistance to "last-resort" clinical antibiotics.
-
Mobilizable Resistance Gene (MRG) Analysis: Bioinformatic screening to ensure no presence of genes on mobile genetic elements (plasmids/transposons) that could transfer resistance to host microbiota.
Our Product Portfolio
In addition to our CRO services, we offer a catalog of products to serve as benchmarks for your NGP programs:
-
Reference Probiotic Strains: A library of well-characterized Enterococcus and Lactobacillus strains for use as positive controls.

Frequently Asked Questions (FAQs)
Why are goat-derived strains considered superior for NGP development?
Ruminants like goats have evolved complex microbial ecosystems to digest fibrous plant materials. Strains isolated from these environments, particularly those from healthy, conventionally managed animals, often possess superior environmental resilience (acid/bile tolerance) and unique metabolic pathways compared to standard laboratory strains.
Is Enterococcus safe for use in human probiotics?
While some Enterococcus strains are pathogens, many species like E. faecium have a long history of safe use in food and medicine. The key lies in rigorous screening for virulence factors and antibiotic resistance genes. Our Biological Safety Test Services are specifically designed to differentiate safe probiotic candidates from potential risks.
Can Creative Biolabs help with large-scale production?
Yes. We offer Microbial Fermentation and Lab-Scale Production services. We optimize growth kinetics and stabilization (e.g., freeze-drying) to ensure high viability and potency in the final dosage form.
How do you evaluate "antipathogenic activity"?
We use a multi-tiered approach: starting with agar well diffusion to identify broad-spectrum inhibition, followed by co-culture assays to simulate host-pathogen interactions, and finally biochemical analysis to identify the active compounds (e.g., enterocins).
