Biological screening of Nigella damascena for antimicrobial and molluscicidal activities.

The essential oil, various extracts at different polarity, fractions, and pure compounds obtained from Nigella damascena plants and seeds were screened for biological activity. Antimicrobial tests showed the essential oil to be active only against Gram positive bacteria; among the extracts, the BuOH was active against Pseudomonas aeruginosa and Staphylococcus aureus. Molluscicidal activity was absent.

Antimicrobial activity of crude extracts and pure compounds of Hypericum hircinum.

The antimicrobial activity of the n-hexane (H) and chloroform (C) extracts, the methanol extract (M) and its ethyl acetate (E) and n-butanol (B) fractions, and six isolated constituents of the aerial parts of Hypericum hircinum was investigated using an agar diffusion method. The maximum activity was exhibited by the methanolic extract against Staphylococcus aureus, while all pure constituents showed no antimicrobial activity against the tested microorganisms.

Antimicrobial activity of the essential oil of Calamintha nepeta and its constituent pulegone against bacteria and fungi.

The chemical composition of the essential oil of Calamintha nepeta and its antimicrobial activity against Listeria monocytogenes, Bacillus cereus, Salmonella veneziana, S. paratyphi B. S. typhimurium, Fusarium moniliforme, Botrytis cinerea, Aspergillus niger and Pyricularia oryzae have been studied. Moreover the main constituents of the oil (limonene, menthone, pulegone, menthol) have been tested against the same microorganisms. Only pulegone showed antimicrobial activity, particularly against all the Salmonella species.

Composition and antimicrobial properties of essential oils of four Mediterranean Lamiaceae.

Essential oils from Satureja montana L., Rosmarinus officinalis L., Thymus vulgaris L., and Calamintha nepeta (L.) Savi, were chemically analysed and their antimicrobial and fungicide activities evaluated on the basis of their minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). All four oils have a biotoxic effect, the most active being those from Calamintha and Thymus.

[Salmonella in the province of Livorno. Epidemiological study over the last five years].

The authors refer on Salmonella species isolated from carriers, in USL 13 country, during the period of five years 1984-1988 in the microbiological laboratories of S.M.P. USL 13. N. 1240 Salmonella strains were isolated. N. 62 serotypes have been recognized of which about 77% were of the groups B, C1, E1. The trial shows a high positivity of more rare serotypes especially in summer period.
