| comparative review of the carbapenems. | the carbapenems are beta-lactam antimicrobial agents with an exceptionally broad spectrum of activity. older carbapenems, such as imipenem, were often susceptible to degradation by the enzyme dehydropeptidase-1 (dhp-1) located in renal tubules and required co-administration with a dhp-1 inhibitor such as cilastatin. later additions to the class such as meropenem, ertapenem and doripenem demonstrated increased stability to dhp-1 and are administered without a dhp-1 inhibitor. like all beta-lactam ... | 2007 | 17488146 |
| 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 resista ... | 2007 | 17487947 |
