Evolutionary Origins and Virulence Determinants of ST25 Hypervirulent <i>Klebsiella pneumoniae</i> in Swine: Genomic Insights and Functional Validation. [PDF]

open access: yesTransbound Emerg Dis
The global spread of multidrug‐resistant hypervirulent Klebsiella pneumoniae (MDR‐HvKp), among which carbapenem‐resistant strains are of major concern, poses a severe threat to public health due to its high mortality rate and extremely limited treatment options.

The pharmacokinetic study of tacrolimus and Wuzhi capsule in Chinese liver transplant patients

open access: yesFrontiers in Pharmacology, 2022
Objectives: Wuzhi Capsule (WZC) is often administrated with tacrolimus in liver transplant patients to reduce the toxicity of tacrolimus and relieve the financial burden of patients. We aimed to investigate the interaction between Wuzhi Capsule (WZC) and

Urine-mediated suppression of Klebsiella pneumoniae mucoidy is counteracted by spontaneous Wzc variants altering capsule chain length

open access: yesmSphere, 2023
Klebsiella pneumoniae is a hospital-associated pathogen primarily causing urinary tract infections (UTIs), pneumonia, and septicemia. Two challenging lineages include the hypervirulent strains, causing invasive community-acquired infections, and the ...

Prevalence of multidrug-resistant hypervirulent Klebsiella pneumoniae without defined hypervirulent biomarkers in Anhui, China: a new dimension of hypervirulence

open access: yesFrontiers in Microbiology, 2023
Klebsiella pneumoniae is an opportunistic pathogen that mainly causes nosocomial infections and hospital-associated pneumonia in elderly and immunocompromised people. However, multidrug-resistant hypervirulent K.
