Chirality (chemistry) Chirality /kaÉªËrÃ¦lÉªti/ is a geometric property of some molecules and ions. A chiral molecule/ion is non-superposable on its mirror image. The presence of an asymmetric carbon center is one of several structural features that induce chirality in organic and inorganic molecules.
Increasingly, Klebsiella bacteria have developed antimicrobial resistance, most recently to the class of antibiotics known as carbapenems. Klebsiella bacteria are normally found in the human intestines (where they do not cause disease). They are also found in human stool (feces). In healthcare settings, Klebsiella infections commonly occur among sick patients who are receiving treatment for other conditions.
One research paper found 4% of the lettuce they tested containedKlebsiella pneumoniae4. As a general rule, Klebsiella infectionstend to occur in people with a weakened immune system. Many of these infectionsare obtained when a person is in the hospital for some other reason. The mostcommon infection caused by Klebsiella bacteria outside the hospital ispneumonia. Klebsiella pneumonia tends to affectpeople with underlying diseases, such as alcoholism, diabetes and chronic lungdisease.
