Staphylococcus growth inhibition

PolyPs display antiseptic, cytoprotective and antiviral activities. At a concentration of 0.1 % or higher, PolyP had a bacteriocidal effect on log arithmic-phase Bacillus cereus cells (Maier et al., 1999). The growth inhibition effect of PolyP was observed with Staphylococcus aureus (Jen and Shelef, 1986 Matsuoka et al., 1995) and Aerornonas hydrophila (Palumbo et al., 1995).

Figure 3 Comparison of growth inhibition o/Staphylococcus aureus by crude extracts (50% acetone) of seed interiors from a typical subset of large seeded species in our studies.

The aqueous/methanol fraction of the dichloromethane extract of Carthamus lanatus L. exhibited a high rate of antibacterial activity against Staphylococcus aureus and Escherichia coli [35], while crude dichloromethane extracts of the aerial parts and roots of Leontopodium alpinum Cass, exhibited significant growth inhibition of Bacillus subtilis, Escherichia coli. Pseudomonas aeruginosa. Staphylococcus aureus and Streptococcus pyogenes [36]. 

Bioassay-guided fractionation of an extract of Artemisia annua was conducted in order to assess the possible presence in the plant material of inhibitors of bacterial multidrug resistance pumps [218]. Fractions were tested for Staphylococcus aureus growth inhibition in the presence of a subinhibitory dose of weak antibacterial alkaloid berberine. Active fractions yielded the flavones chrysoplenol D and chrysoplenetin,... 

St. John s wort has been used topically for wound healing for hundreds of years. Antibacterial properties have been reported as early as 1959, with hyperforin found to be the active component. Using multiple concentrations, it was discovered that no hyperforin dilutions had antimicrobial effects on Gram-negative bacteria or Candida albicans. There was, however, growth inhibition for all of the Gram-positive bacteria tested, some with the lowest dilution concentration of 0.1 pg/mL. Hyperforin was also shown to be effective at inhibiting methacillin-resistant Staphylococcus aureus (25).

Further work (c/. Vol. 8, p. 30) has indicated the considerable geographic variation in the halogenated monoterpenoid content of P. cartilagineum. Both plocamene B (96) and violacene (2) exhibit growth inhibition against mosquito larvae,and antibacterial activity against Staphylococcus aureus has been reported for ochtodene (92 X = Cl, Y = Br)."

Corollosporine A (26) showed moderate growth inhibition of gramnegative Escherichia coli and Proteus mirabilis) and gram-positive bacteria Staphylococcus aureus. Micrococcus flavus and Bacillus subtilisy. 

In 1928/29 Alexander Fleming discovered that the growth of a staphylococcus was inhibited by a substance produced by a mold. Since the mold in question was identified as Penicillium notatum, Fleming named the substance penicillin however, he did not make any further systematic attempts to isolate it.

In vitro cytotoxic activity was found against human leukemia (HL-60) cells exposed to coumarins (especially dipetaUne) and lignans (asarinin and sesamin) isolated from the root bark and fresh stems of northern prickly ash. Cytotoxic effects on human tumor cell lines were also found from crude extracts of the berries and furanocoumarins isolated therefrom (psoralen, isoimperatoin, and xanthox-toxin). The bark of southern prickly ash has shown in vitro growth inhibition of a methi-cillin-resistant strain of Staphylococcus aureus. Activity was largely attributed to the alkaloid chelerythrine, which showed activity against various other methicillin-resistant strains of the bacteria. ... 

It is now believed that many of our useful drugs exert their beneficial action by the inhibition of enzyme activity in bacteria. Some bacteria, such as staphylococcus, require for their growth the simple organic compound poraaminobenzoic...
