Hypermucoviscosity in Klebsiella pneumoniae: manifestation, regulation, and roles in pathogenesis [PDF]
Journal of BacteriologyIn recent years, Klebsiella pneumoniae (Kpn) has evolved into a global public health threat. Convergent Kpn lineages that are both hypervirulent and multidrug-resistant have emerged and can cause community-acquired, drug-resistant infections, with ...
