It is a long, slender, and fast-moving snake, identified by its distinctive stripes running down the length of its body. They primarily feed on lizards and small rodents.

Carbapenems
-
Carbapenems are a subclass of antibiotics called beta-lactam antibiotics (antibiotics that have a chemical structure called a beta-lactam ring). Beta-lactam antibiotics also include cephalosporins, monobactams, and penicillins.
Carbapenems are broad-spectrum antibiotics. That is, they are effective against many types of bacteria, including bacteria that are resistant to many other antibiotics.
Carbapenems include the following:Doripenem
Ertapenem
Imipenem
MeropenemCarbapenems must be given by injection. They are often used with aminoglycosides to treat some infections because using them together enhances the effectiveness of both antibiotics.
Imipenem is always given in combination with other drugs cilastatin and sometimes also relebactam. Cilastatin and relebactam are not antibiotics. They help prolong the effect of imipenem by protecting it from being broken down.
Some bacteria have an outer covering (cell wall) that protects them. Like other beta-lactam antibiotics, carbapenems work by preventing bacteria from forming this cell wall, resulting in death of the bacteria.
Rarely, because carbapenems are structurally similar to the penicillins, people who have an allergic reaction to penicillins have an allergic reaction to carbapenems.
