Klebsiella, Enterobacter, and Serratia Infections
Introduction
 are closely related Overview of Gram-Negative Bacteria that occasionally infect the urinary tract or respiratory tract of people in hospitals or in long-term care facilities. These bacteria may infect the urinary or respiratory tract, intravenous catheters used to give drugs or fluids, burns, wounds made during surgery, or the bloodstream. Identifying the bacteria in a sample taken from blood or from infected tissue confirms the diagnosis. Infections caused by all three bacteria are treated with antibiotics given by vein (intravenously). (See also Overview of Bacteria .) Klebsiella,Enterobacter, andSerratiabacteria reside in the intestine of many healthy people and rarely cause infection in them. Infections with these bacteria are often acquired in hospitals and long-term care facilities. They usually occur in people whose resistance to infection is weakened and/or who have a medical device (such as catheters, drains, and airway tubes) in their body. These bacteria may infect different places in the body: Urinary or respiratory tract (causing Overview of Pneumonia , Catheters inserted into a vein (intravenous catheter), used to administer drugs or fluids Burns None Wounds made during surgery Bloodstream (causing Bacteremia or bacteria cause pneumonia in people who live outside a health care facility (in the community), usually in people with an alcohol use disorder, older people, people with diabetes, or people with a weakened immune system. Typically, this severe infection causes cough, bringing up a sticky, dark brown or dark red sputum, and collections of pus ( Abscess in the Lungs ) in the lungs or in the membrane between the lungs and chest wall (empyema). bacteria are able to multiply and produce the toxin. However, antibiotic-associated colitis usually results from toxins produced by Clostridioides (formerly Clostridium) difficile–Induced Colitis .
