Bacteriolysis by a Species of Streptomyces [PDF]

Journal of General Microbiology, 1951
SUMMARY: The lysis of dead Bacterium coli by concentrates prepared from filtrates of a Streptomyces sp. is probably due to proteolysis. In any event the lysis can be accounted for by proteolysis, even if the action of other bacteriolytic enzymes cannot be excluded.

Image-Based Dynamic Phenotyping Reveals Genetic Determinants of Filamentation-Mediated β-Lactam Tolerance

Frontiers in Microbiology, 2020
Antibiotic tolerance characterized by slow killing of bacteria in response to a drug can lead to treatment failure and promote the emergence of resistance.

Dual Inhibitory Activity of Petroselinic Acid Enriched in Fennel Against Porphyromonas gingivalis

Frontiers in Microbiology, 2022
Increasing evidence has shown that a major periodontal pathobiont, Porphyromonas gingivalis, triggers oral dysbiosis leading to deterioration not only of periodontal health, but also of several systemic conditions.

Model-Driven Controlled Alteration of Nanopillar Cap Architecture Reveals its Effects on Bactericidal Activity

Microorganisms, 2020
Nanostructured surfaces can be engineered to kill bacteria in a contact-dependent manner. The study of bacterial interactions with a nanoscale topology is thus crucial to developing antibacterial surfaces.

Molecular basis of IRGB10 oligomerization and membrane association for pathogen membrane disruption

Communications Biology, 2021
Ha et al. present a crystal structure of mouse IRGB10, a mouse interferon-inducible GTPase that mediates bacteriolysis in cell autonomous immunity. With further mutagenesis studies, they show that IRGB10 bound to GDP forms an inactive head-to-head dimer,

Mycobacteriophages in diagnosis and alternative treatment of mycobacterial infections

Frontiers in Microbiology, 2023
Antimicrobial resistance is an increasing threat to human populations. The emergence of multidrug-resistant “superbugs” in mycobacterial infections has further complicated the processes of curing patients, thereby resulting in high morbidity and ...

Intracellular bacteriolysis contributes to pathogenicity of Staphylococcus aureus by exacerbating AIM2-mediated inflammation and necroptosis

, 2022
Staphylococcus aureus can survive within phagocytes. Indeed, we confirm in this study that approximately 10% of population persists in macrophages during S.

Listeria monocytogenes requires cellular respiration for NAD+ regeneration and pathogenesis

eLife, 2022
Cellular respiration is essential for multiple bacterial pathogens and a validated antibiotic target. In addition to driving oxidative phosphorylation, bacterial respiration has a variety of ancillary functions that obscure its contribution to ...

WhyD tailors surface polymers to prevent premature bacteriolysis and direct cell elongation in Streptococcus pneumoniae

eLife, 2022
Penicillin and related antibiotics disrupt cell wall synthesis in bacteria causing the downstream misactivation of cell wall hydrolases called autolysins to induce cell lysis.
