Full-service antibiotic development program combining in vitroex vivo and in vivo animal model efficacy, toxicity and mechanism of action evaluations for antibacterial and antifungal testing.

In vitro and in vivo services for ESKAPE pathogens, clinical and laboratory strains, drug-resistant strains, a wide variety of gram positive, gram negative and anaerobic organisms, and fungal organisms. Bacterial stock production services are also available.

Antibacterial testing services are available for the evaluation of small molecules, natural products, immune modulators, biologics and therapeutic antibodies and provide necessary support from initial discovery, structure-activity relationship evaluation, lead identification and IND-directed preclinical development.

Customized assay design, endpoint modification, and internalization and validation of pre-developed or published methods are available.
