Core Technology & Innovation
Harnessing nature's precision lytic predators to conquer Antimicrobial Resistance (AMR) in the post-antibiotic era.
Bacteriophage Lytic Mechanism vs. Antibiotics
Conventional veterinary antibiotics act via broad chemical suppression, indiscriminately destroying beneficial intestinal symbionts (such as Lactobacillus and Bifidobacterium). This collateral damage destabilizes gut mucosal immunity and accelerates horizontal transfer of antibiotic resistance genes.
Bacteriophages, conversely, are natural precision bio-predators. Their tail fiber Receptor-Binding Proteins (RBPs) act as molecular "guided missiles," binding exclusively to surface receptors of specific target pathogens. After injecting genetic material, the phage replicates hundreds of progeny within 20?30 minutes, culminating in holin-endolysin mediated cell wall rupture. Once the host pathogen is eliminated, residual phages are harmlessly metabolized by the host.
Comparative Performance Metrics
| Parameter | New-Line Phage Cocktails | Conventional Antibiotics |
|---|---|---|
| Target Specificity | Ultra-high (Target species only) | Broad-spectrum (Destroys microflora) |
| Resistance Development | Co-evolving (Prevented by cocktails) | Rapid MDR & superbug emergence |
| Chemical Residues | Zero (Pure protein & nucleic acid) | Tissue residues, strict withdrawal |
| Ecological Footprint | 100% Biodegradable & safe | Accumulates in soil and groundwater |
| Dosage Dynamics | Self-amplifying at infection site | Metabolized and cleared rapidly |
Multivalent "Cocktail" Synergistic Engineering
Single-phage treatments can occasionally select for bacterial receptor mutation. To definitively solve this challenge, New-Line Biotech utilizes proprietary epidemiological genomic surveillance to formulate multi-strain cocktails. By combining phages that target complementary, non-overlapping receptor families (e.g. LPS core oligosaccharides, O-antigens, outer membrane porins, and flagellar motors), bacterial mutational fitness costs are rendered fatal, completely blocking resistance escape.
GMP Automated Production & Quality Control
Our facilities in Weifang encompass 6 automated fermentation production lines equipped with real-time dissolved oxygen, pH, and nutrient feed controls. Downstream purification relies on Tangential Flow Filtration (TFF) and ultra-clean freeze drying, guaranteeing stability, purity, and high viable titers across global shipping environments.
