Thirteen-lined ground squirrels (Spermophilus tridecemlineatus) harbor multiantibiotic-resistant bacteria.
Whether wild-caught animals used for biomedical research carry antibiotic-resistant bacteria is not well studied. Thirteen- lined ground squirrels (Spermophilus tridecemlineatus) are small mammals used to study hibernation. These animals are captured from the wild or are born in laboratory animal facilities to wild-caught mothers. Because microorganisms harbored by 13-lined ground squirrels may be pathogenic to their caretakers and other laboratory animals, learning more about antibiotic resistance in these animals could be useful. In this study, tetracycline- and chloramphenicol-resistant Morganella morganii and multidrug resistant Stenotrophomonas maltophilia were isolated from the ceca of four 13-lined ground squirrels. These findings support further study of antibiotic-resistant bacterial populations in wild-caught mammals used as laboratory models.
