A Klebsiella pneumoniae antibiotic resistance mechanism that subdues host defences and promotes virulence [PDF]

open access: yes, 2017
Klebsiella pneumoniae is an important cause of multidrug-resistant infections worldwide. Recent studies highlight the emergence of multidrug-resistant K.\ua0pneumoniae strains which show resistance to colistin, a last-line antibiotic, arising from ...

Hypervirulent antibiotic-resistantClostridium difficilein Europe [PDF]

open access: yesMicrobial Ecology in Health & Disease, 2008
Recently, several Clostridium difficile outbreaks due to PCR ribotype 027, associated with increased disease severity and death, have been reported in North America and in several European countries. This strain is toxinA/toxinB-positive, contains the genes for binary toxin and has an 18 bp deletion and a frameshift mutation in the gene tcdC ...

Sputum Gram stain of hypervirulent Klebsiella pneumoniae

open access: yesJournal of General and Family Medicine, 2023
Hypervirulent Klebsiella pneumoniae has virulence genes relevant to capsule overproduction, which could lead to the finding of thick transparent area ("halo") in Gram stain. In sputum Gram stain, observation of a large Gram-negative rod with a thick capsule may not only indicate that it is K. pneumoniae but also that it is a highly virulent strain.
