Bacterial Infections

Sepsis

Modeling the profound systemic and immunological dysregulation of clinical sepsis requires a highly translatable, polymicrobial in vivo platform. At BioLegacy, we provide this definitive assessment using the gold-standard cecal ligation and puncture (CLP) model, which accurately recapitulates the complex pathophysiology of human abdominal sepsis. Our expertise in this surgically-induced model allows for a robust evaluation of your therapeutic’s ability to modulate the cytokine cascade, preserve organ function, and ultimately improve survival, delivering the pivotal data your program requires.

  • Cecal Ligation and Puncture (CLP) Models: The gold-standard surgical model of polymicrobial sepsis, providing the highest clinical relevance to human disease.
  • Systemic Cytokine Storm Profiling: Multiplex analysis of plasma to quantify the hyperinflammatory response and its modulation.
  • Multi-Organ Dysfunction Scoring: Histopathological and biochemical analysis to assess downstream organ damage.

Bacterial Infections

While standard infection models are the foundation of anti-infective research, the true quality of the data is driven by the surrounding analytical and scientific expertise. At BioLegacy, our strategic advantage lies in this integrated support. Our studies are conducted by a highly experienced team within a secure BSL-2 environment, ensuring data integrity and precise clinical monitoring, while our in-house bioanalytical platforms provide a deep, quantitative understanding of the host-pathogen interaction. By seamlessly combining bacterial load quantification with in-depth immunophenotyping, cytokine profiling, and integrated PK/PD analysis, we deliver a multi-faceted, mechanistic data package that clearly differentiates your compound’s efficacy.

  • E. coli Drug-Resistant Strains: Expertise in robust infection models using carbapenem-resistant Enterobacteriaceae (CRE) to assess novel antibiotic efficacy.
  • S. aureus Drug-Resistant Strains: Validated models, including methicillin-resistant Staphylococcus aureus (MRSA), for definitive in vivo proof-of-concept studies.
  • Thigh & Systemic Infection Models: Clinically relevant platforms to assess therapeutic efficacy by quantifying bacterial burden (CFU) in both localized and systemic infections.
  • Anti-Infective PK/PD Analysis: Integrated pharmacokinetic and pharmacodynamic analysis to optimize dosing regimens and establish exposure-response relationships.
