    Abstract:
    Infection of laboratory mice with Helicobacter spp. is a serious problem for many laboratory animal facilities worldwide. Rederivation and antibiotic treatment are two of the most common methods used to eliminate the bacterial infection from rodent colonies. Forty-seven newly imported mice were suspected to be positive for Helicobacter infection based on PCR analysis of pooled fecal samples from sentinel animals. We treated the mice with a medicated feed containing four antibiotic compounds (amoxicillin, clarithromycin, metronidazole, omeprazole). After eight weeks of continuous administration the animals were negative for H. bilis and H. hepaticus. Frequent retesting of the animals for up to one year proved that the mouse colony remained negative for Helicobacter spp.
