This study examined bacteriostatic and bactericidal activities of oral and parenteral antibiotics for penicillin-susceptible and intermediately and fully penicillin-resistant pneumococci. beta-Lactamase inhibitors did not affect beta-lactam results. The activities of ampicillin, amoxicillin +/- clavulanate, WY-49605, cefuroxime, cefpodoxime, cefdinir, cefixime, and cefaclor against two penicill...

background and objectives: pseudomonas aeruginosa is an opportunistic pathogen that can produce biofilm. biofilm is a complex, three dimensional structure in which microorganisms are attached to a surface and embedded in a matrix made of extracellular polymers. due to high resistance to antimicrobial agents, biofilms create difficulties in various situations in healthcare. in this study, antibi...

Herein, it is investigated if black diamond useful in a bactericidal surface. Black derived from silicon, silicon surface structured into nanosized needles. obtained by coating with thin film, rendering the nanostructures more robust. The and antibacterial properties of fluorine‐terminated hydrogen‐terminated diamonds those for flat surfaces (on silicon) same terminations are studied. ability t...

Group IIA secreted phospholipase A(2) (sPLA2) is known to display potent Gram-positive bactericidal activity in vitro and in vivo. We have analyzed the bactericidal activity of the full set of recombinant murine and human groups I, II, V, X, and XII sPLA2s on Listeria monocytogenes, Staphylococcus aureus, and Escherichia coli. The rank order potency among human sPLA2s against Gram-positive bact...
