The main antimicrobial substance in Salvia officinalis tincture detected was further characterized by microchemical reactions, Aliivibrio fischeri, β-glucosidase and acetylcholinesterase (bio assays as well as mass spectrometry.
The fraction was acidified to pH 3.0 using 2 M sulfuric acid and extracted three times with chloroform, resulting in a moderately polar extract that contained the main antimicrobial activity.
This review presents a brief history of discovery of the main antimicrobial classes (arsphenamines, β-lactams, sulphonamides, polypeptides, aminoglycosides, tetracyclines, amphenicols, lipopeptides, macrolides, oxazolidinones, glycopeptides, streptogramins, ansamycins, quinolones, and lincosamides) that have changed the landscape of contemporary medicine.
AtWAKL10 is also consistently co-expressed with genes encoding enzymes that function in the biosynthesis of camalexin, which is the main antimicrobial phytoalexin in Arabidopsis and is synthesized in response to a broad range of biotrophic and necrotrophic pathogens [59].
Vast majority of the strains were susceptible to main antimicrobial agents.
Vancomycin, a glycopeptide is currently the main antimicrobial agent available to treat life-threatening infections with MRSA.
However, strains resistant to the main antimicrobial agents may emerge [ 10] and lead on to treatment inhibition.
Data from 1997 to 2004 show that the main antimicrobial classes used in livestock are tetracycline and trimethoprim sulfonamide combinations.
Of the four main antimicrobial indicator classes studied, the highest proportion of prescriptions were for penicillins (J01C - 53.4 %), followed by the macrolides, lincosamides and streptogramins (J01F – 17.5 %).
Such incidence of vancomycin resistant Staphylococci is worrisome to the clinicians as it is currently the main antimicrobial agent available to treat life-threatening infections with MRSA.
