Cytotoxicity and Antibacterial Activity of Alginate Hydrogel Containing Nitric Oxide Donor and Silver Nanoparticles for Topical Applications.

ACS Biomaterials Science & Engineering, 2020
Nitric oxide (NO) and silver nanoparticles (AgNPs) are well-known for their antibacterial activity. In this work, S-nitroso-mercaptosuccinic acid (S-nitroso-MSA), a NO donor, and green tea synthesized AgNPs were individually or simultaneously ...

Antibacterial Activity of Lonchocarpol A [PDF]

Journal of Natural Products, 1998
Lonchocarpol A, a flavanone, demonstrates in vitro inhibitory activity against methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecium. This activity is antagonized by mouse plasma, which may account for its lack of in vivo activity.

Antibacterial Activity of Temocillin1

Drugs, 1985
The in vitro antibacterial activity of temocillin, a new penicillin, was determined in quantitative broth dilution tests, and compared with that of mezlocillin, piperacillin, cephazolin and cefotaxime. 805 clinical isolates of the Enterobacteriaceae family were tested, with temocillin exhibiting a high level of antibacterial activity against the ...

Antibacterial activity of lomefloxacin

Journal of Antimicrobial Chemotherapy, 1991
Lomefloxacin has marked activity against Gram-negative bacilli including Enterobacteriaceae, non-fermenting strains and Haemophilus influenzae with 98% of all isolates tested having MICs of 0.25 mg/l or less. Sixty-eight per cent of Pseudomonas aeruginosa strains were sensitive to 1 mg/l with a few strains resistant to 8 or 16 mg/l. Gram-positive cocci

Antibacterial Activity of the Staphylococcus

Nature, 1947
THE observation that the Staphylococcus can inhibit the growth of other bacteria has been recorded, in some fifty papers over a period of sixty years, beginning with Babes1, who showed that a Staphylococcus inhibited the growth of B. anthracis and of another Staphylococcus.
