In vivo Microbiology


With the rising prevalence of drug-resistant microorganisms, effective and potent anti-infective agents are becoming increasingly more relevant in order to treat infectious diseases.  The scientific team at Pharmacology Discovery Services works diligently with our clients to provide a robust portfolio of in vivo Anti-infective models to support the discovery and development of novel antimicrobial therapies. 

Our team of Technical and Study Directors have experience in Anti-infective drug development and clinical microbiology.  We can meet a variety of study endpoints to generate the high-quality, reproducible data your projects require including minimal data scatter and dose-response to standard antimicrobial agents.  Our models have been used to test small molecules, drug combinations, biologics, RNAi, liposomal formulations, nanoparticles, and vaccines.  To meet the needs of your specific Anti-infective drug discovery project we also have the flexibility and expertise to develop custom in vivo models.

Determine In vivo Efficacy with Survival and Tissue Burden Models

We have over 50 validated infection models with clinically relevant pathogens:

  • Ocular, peritonitis, pneumonia or sepsis
  • Skin, thigh muscle, wound or vaginal
  • Models with multi-drug resistant (MDR) bacterial pathogens

Pathogen types include:

  • Fungi: C. albicans, A. fumigatus
  • Gram-negative bacteria: A. baumannii, E. coli, K. pneumoniae, N. gonorrhoeae, P. aeruginosa
  • Gram-positive bacteria: E. faecalis, S. aureus, S. epidermidis, S. pneumoniae, S. pyogenes

Flexible Dosing Routes:

  • ID, IM, IN, IP, IT, IV, PO, RO, SC or topical
  • Continuous IV infusion or dose fractionation

Multiple Readouts Available

  • Survival or microbial counts
  • Counts of resistant microbial variants
  • Histopathology
  • PK exposure
  • Cytokine profile
  • Flow cytometry
  • quantitative RT-PCR

In vivo Pharmacology Expertise

Each of our Technical Directors specializes in selected therapeutic areas so they may provide expert scientific support to our clients.  This involves consulting with clients to identify an appropriate model to meet their scientific objectives, designing studies and writing the custom protocols and statements of work (SOWs) to meet quality assurance guidelines.  They also work closely with our Study Directors to assure that SOWs are clear and that all methods and timelines are feasible.  Our laboratory staff also averages 15 years of experience conducting in vivo pharmacology studies.
