A barrier breakdown with potential human health implications while not affecting animal welfare

摘要

Citrobacter freundii is a human pathogen that is routinely carried within the human intestine and is not usually a concern to healthy individuals. It is not routinely found in rodents and is not routinely screened for.While performing our routine health screening, results showed that we had a positive test for Citrobacter freundii. This positive result was initially thought to have been brought in from a member of the staff but upon further investigations it was seento be bought in from an outside animal source.
