Plasmodium sporozoites require the protein B9 to invade hepatocytes

open access: yesiScience, 2023
Summary: Plasmodium sporozoites are transmitted to a mammalian host during blood feeding by an infected mosquito and invade hepatocytes for initial replication of the parasite into thousands of erythrocyte-invasive merozoites.

Transmission of pLVPK-like virulence plasmid in Klebsiella pneumoniae mediated by an Incl1 conjugative helper plasmid

open access: yesiScience, 2022
Summary: We previously reported the recovery of five ST11 carbapenem resistant hypervirulent Klebsiella pneumoniae (CR-HvKP) strains that harbored pLVPK-like virulence plasmids, yet molecular mechanisms underlying acquisition of virulence plasmid by ST11

Moraxella catarrhalis evades neutrophil oxidative stress responses providing a safer niche for nontypeable Haemophilus influenzae

open access: yesiScience, 2022
Summary: Moraxella catarrhalis and nontypeable Haemophilus influenzae (NTHi) are pathogenic bacteria frequently associated with exacerbation of chronic obstructive pulmonary disease (COPD), whose hallmark is inflammatory oxidative stress.

Reactive oxygen species accelerate de novo acquisition of antibiotic resistance in E. coli

open access: yesiScience, 2023
Summary: Reactive oxygen species (ROS) produced as a secondary effect of bactericidal antibiotics are hypothesized to play a role in killing bacteria. If correct, ROS may play a role in development of de novo resistance.

Structural insights into the inhibition of bacterial RecA by naphthalene polysulfonated compounds

open access: yesiScience, 2021
Summary: As a promising target for alternative antimicrobials, bacterial recombinase A (RecA) protein has attracted much attention for its roles in antibiotic-driven SOS response and mutagenesis. Naphthalene polysulfonated compounds (NPS) such as suramin
