Risk Factors for New Zealand Sea Lion (Phocarctos hookeri) Pup Mortality: Ivermectin Improves Survival for Conservation Management

Frontiers in Marine Science, 2021
Septicaemia due to hypervirulent (HV) Klebsiella pneumoniae is the leading cause of neonatal pup mortality in endangered New Zealand sea lions (Phocarctos hookeri) at Enderby Island, in the New Zealand sub-Antarctic.

Serotypic and Genomic Diversity of Vibrio anguillarum in Rainbow Trout Farms in Turkey: Implications for Vibriosis Control and Vaccine Candidate Selection

Journal of Fish Diseases, EarlyView.
ABSTRACT Outbreaks of vibriosis caused by Vibrio anguillarum are a persistent constraint on rainbow trout (Oncorhynchus mykiss) aquaculture. However, information on the population structure of field strains in Turkey has been lacking. Here, we report the first systematic serotypic, proteomic, and genomic characterization of 23 V.

Naturally Occurring CodY Variants Alter Ligand Binding, DNA Target Affinity, and Virulence in Clostridioides difficile

Molecular Microbiology, EarlyView.
Single amino acid substitutions in the global regulator CodY can alter nutrient sensing and virulence regulation in Clostridioides difficile. We show that the CodY(Y146N) and CodY(V58A) variants display altered ligand binding and reduced promoter binding, leading to derepression of toxin regulatory pathways and increased virulence in vivo.

Hypervirulent Klebsiella pneumoniae ST23: Hypervirulence Meets Antimicrobial Resistance

eMicrobe
Hypervirulent Klebsiella pneumoniae can cause community-acquired invasive infections such as pyogenic liver abscess and endophthalmitis in healthy individuals compared to the classical K. pneumoniae, causing opportunistic healthcare-associated infections. Globally, K.

Klebsiella species: Taxonomy, hypervirulence and multidrug resistance

eBioMedicine, 2022
Members of the genus Klebsiella have rapidly evolved within the past decade, generating organisms that simultaneously exhibit both multidrug resistance and hypervirulence (MDR-hv) phenotypes; such organisms are associated with severe hospital- and community-acquired infections.

Revisiting the Molecular Roadmap for Sugar Crops: Genome Reading, Trait Writing and Variety Redesigning

Plant Biotechnology Journal, EarlyView.
ABSTRACT Sugar crops, including but not limited to sugarcane, sugar beet, sweet sorghum and stevia, are major sources of sugar production in the world. However, conventional breeding approaches, limited by long breeding cycles, low efficiency and restricted capacity to improve complex traits in sugar crops, are increasingly insufficient to address the ...

Engineered surface strategies to manage dental implant‐related infections

Periodontology 2000, EarlyView.
Abstract When exposed to the oral environment, dental implants, like natural surfaces, become substrates for microbial adhesion and accumulation, often leading to implant‐related infections—one of the main causes of implant failure. These failures impose significant costs on patients, clinicians, and healthcare systems.

Occurrence of colistin-resistant hypervirulent Klebsiella variicola [PDF]

Journal of Antimicrobial Chemotherapy, 2018
A colistin-resistant mucoid Klebsiella strain was recovered from the blood of a patient in China. Hypervirulence has been reported in Klebsiella pneumoniae, but not in other Klebsiella spp. The strain was suspected to be hypervirulent and was therefore characterized.The strain was subjected to genome sequencing using both the short-read Illumina HiSeq ...
