Genetic switch to hypervirulence reduces colonization phenotypes of the globally disseminated group A Streptococcus M1T1 clone [PDF]

, 2010
Background. The recent resurgence of invasive group A streptococcal disease has been paralleled by the emergence of the M1T1 clone. Recently, invasive disease initiation has been linked to mutations in the covR/S 2-component regulator.

Deciphering the Epidemiological Characteristics and Molecular Features of blaKPC–2- or blaNDM–1-Positive Klebsiella pneumoniae Isolates in a Newly Established Hospital

Frontiers in Microbiology, 2021
The emergence of hypervirulent carbapenem-resistant Klebsiella pneumoniae (hv-CRKP) was regarded as an emerging threat in clinical settings. Here, we investigated the prevalence of CRKP strains among inpatients in a new hospital over 1 year since its ...

Phenotypic and Genotypic Characterization of a Hypervirulent Carbapenem-Resistant Klebsiella pneumoniae ST17-KL38 Clinical Isolate Harboring the Carbapenemase IMP-4

Microbiology Spectrum, 2022
Carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-hvKP) is a threat to global public health. We characterized a sequence type 17 (ST17) K. pneumoniae clinical isolate that was resistant to carbapenems and belonged to serotype KL38/O2.

Construction of a Hypervirulent and Specific Mycoinsecticide for Locust Control [PDF]

Scientific Reports, 2014
Locusts and grasshoppers (acridids) are among the worst pests of crops and grasslands worldwide. Metarhizium acridum, a fungal pathogen that specifically infects acridids, has been developed as a control agent but its utility is limited by slow kill time and greater expense than chemical insecticides.
