Charles River conducts a wide range of efficacy studies for veterinary and biocide products to determine antimicrobial activity. We conduct studies to assess the effects of antimicrobial residues on human gut flora, including in vitro model systems designed to monitor the potential for the development of resistance. We also conduct sterility, preservative efficacy and microbial limit testing, often working to client protocols.

Our experienced microbiologists offer bacteriology services to investigate the effect of animal feed additives on the shedding of zoonotic organisms, such as Salmonella spp. and Campylobacter, by food-producing animals.

As a result of the increasing concern worldwide regarding the spread of antibiotic resistance in bacteria, we offer a full monitoring service including collection and maintenance of zoonotic organisms and bacteria as well as data analysis, as required by the governing regulatory authorities.
