Image-based dynamic phenotyping reveals genetic determinants of filamentation-mediated beta-lactam tolerance [PDF]

, 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.

Shorter Antibacterial Peptide Having High Selectivity for E. coli Membranes and Low Potential for Inducing Resistance

Microorganisms, 2020
Antimicrobial peptides (AMPs) have been recognised as a significant therapeutic option for mitigating resistant microbial infections. It has been found recently that Plasmodium falciparum-derived, 20 residue long, peptide 35409 had antibacterial and ...

Minimum bactericidal concentrations of Propionibacterium acnes isolates from cases of chronic endophthalmitis

Diagnostic Microbiology and Infectious Disease, 1995
Six isolates of Propionibacterium acnes recovered from cases of chronic infectious endophthalmitis following extracapsular cataract extraction were tested for antibiotic susceptibility. All isolates were susceptible to penicillin, cefazolin, and vancomycin with a macrobroth dilution method.

Uji Daya Hambat serta Penentuan Minimum Inhibitor Concentration (MIC) Dan Minimum Bactericidal Concentration (MBC) Ekstrak Daun Bidara Terhadap Bakteri Patogen

Jurnal Pendidikan Teknologi Pertanian, 2023
Bidara leaves contain flavonoids, alkaloids, tannins, phenols and saponins which can act as antibacterial by inhibiting the synthesis of microbial cell walls and disrupting the permeability of microbial cell membranes. This study aims to determine the inhibitory power and minimum concentration of bidara leaf extract (Ziziphus spina-christ L) against ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Effects of UV/H₂O₂ Degradation on the Physicochemical and Antibacterial Properties of Fucoidan

Marine Drugs
The applications of fucoidan in the food industry were limited due to its high molecular weight and low solubility. Moderate degradation was required to depolymerize fucoidan. A few studies have reported that fucoidan has potential antibacterial activity,

Destabilization of α-helical structure in solution improves bactericidal activity of antimicrobial peptides: Opposing effects on bacterial and viral targets [PDF]

, 2016
We have previously examined the mechanism of antimicrobial peptides on the outer membrane of vaccinia virus. Here we show that the formulation of peptides LL37 and magainin-2B amide in polysorbate 20 (Tween-20™) results in greater reductions in virus ...
