Bacteriostatic and bactericidal effects of antibiotics on Bacteroides
The bacteriostatic or bactericidal action of metronidazole, clindamycin, tetracycline, chloramphenicol, cefoxitin and penicillin were determined against sixteen Bacteroides fragilis strains and six B. thetaiotaomicron strains. Drugs were considered bactericidal when minimal bactericidal …

In vivo display: a selection and its derivatives for antimicrobial peptide lead identification
… of growth phenotypes including bacteriolytic, bacteriostatic, bactericidal and growth rate reducing or weakly inhibitory. The cytoplasmic selection, in which the peptide library is fused to the C-terminus (cIVD) or the N-terminus (nIVD) of EmGFP produced 39 and 5 peptides, respectively. Of the …

Design, Synthesis and Evaluation of Organic and Metal Based Antimicrobial Agents
… compounds synthesised were evaluated for their bacteriostatic activity against the Gram-negative bacteria Escherichia coli and Pseudomonas aeruginosa and the Gram positive bacterium Staphylococcus aureus. A selection of the compounds were also evaluated for their in vivo toxicity using the …

Production and characterization of a phage endolysin with putative antimicrobial activity against Cutibacterium acnes
… cell wall. Endolysins retain bactericidal and bacteriostatic activity when applied to bacteria in vitro and are safe for topical application. We hypothesize that the endolysin (ENDL) from the P100.1 C. acnes bacteriophage will exhibit bacteriostatic activity against C. acnes in vitro. This …

Catechin, a novel root exudate of Centaurea stoebe, exhibits pleiotropic effects on the soil microbial community and individual soil isolates, and undergoes chemical changes with numerous abiotic factors from soil
… but instead should be categorized as bacteriostatic. In chapter 5, I extend the findings in chapter 4 to include a repressive effect to various bacterial genera but show that species capable of altering catechin stability can overcome this bacteriostatic effect. More importantly, I …

Size Dependent Antimicrobial Properties of Sugar Encapsulated Gold Nanoparticles
… The microbial assays revealed the dGNPs to be bacteriostatic as well as bactericidal. The dGNPs exhibited their bactericidal action through the disruption of the bacterial cell membrane causing leakage of cytoplasmic content. The overall outcomes of this study suggest that dGNPs hold promise as …

Evaluation of Surface Acetylated Bacterial Cellulose for Antibacterial Wound Dressing Applications
… the host's immune response. Wound dressings with bacteriostatic or bactericidal properties are a promising solution. This study investigated the potential of surface acetylated bacterial cellulose as a novel antibacterial wound dressing. Hydroxyl groups on the surface of bacterial cellulose were …
