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.
Several different species of Klebsiella bacteria can cause infection in humans, but the most common pathogen is K. pneumoniae, which targets the lungs and airways. K. pneumoniae can enter the respiratory tract if it is present on an unsterilized breathing tube, a physician's hands or gloves, or on unwashed bedding.
