|
Definition
In the absence of modification, human proteins are generally nonantigenic. β-Lactams can modify amino groups on human proteins, creating an immunogenic β-lactam hapten. This new antigenic determinant can be recognized as “nonself” by antibodies of the host immune system. |
|
|
Term
resistance to B-lactam agents |
|
Definition
Pharmacologists have addressed this mechanism of resistance: (1) by developing new β-lactam agents, the second- and third-generation cephalosporins that are resistant to degradation by many β-lactamases; and (2) by co-administering β-lactam “decoys,” such as clavulanic acid and sulbactam, that serve as β-lactamase inhibitors |
