Introduction: Medicinal plants are plentiful of bioactive molecules effective against multi-resistance bacteria. The aims of this study were to assess the in vitro antimicrobial activities of essential oils extracted from three Moroccan aromatic plants. Methodology: Analysis of essential oils of Origanum compactum, Rosmarinus officinalis and Pelargonium asperum, collected from different localities in Morocco, were performed using a GC-MS spectrophotometry. Antibacterial activity was evaluated in vitro for five clinical multi-resistant isolates. Results: Origanum showed strong antibacterial activity against tested strains except Pseudomonas aeruginosa while Rosmarinum showed a bactericidal effect against Acinetobacter baumanii, Escherichia coli and Staphylococcus aureus. Pelargonium presented only slight growth inhibition of Staphylococcus aureus on solid medium, but provided bactericidal effect against Acinetobacter baumanii and Staphylococcus aureus. Interestingly, fractions F7 and F8 of Pelargonium which represented only 0.3% and 0.1% of the total mass were found bactericidal respectively against Klebsiella pneumoniae and Pseudomonas aeruginosa. Conclusions: Ours results showed that the antimicrobial activities were variables depending on the chemical composition of essential oils, the fraction used and the microorganism tested.Essential oils fractionation allows detection of bioactive substances, especially those owning antimicrobial activity, present in small quantities.

Three bis-acetylferrocene schiff bases have been synthesized and characterized by IR, 1H NMR, and elemental analysis, the results conformed well with expected structures. The synthesized compounds were screened in vitro for their antimicrobial activity against three Gram-negative (Escherichia coli, Pseudomonas aeruginosa, and Salmonella typhi) and two Gram-positive (Bacillus subtilis and Staphylococcus aureus) bacterial strains. The results showed that these compounds are show excellent antimicrobia activities against Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi ,Bacillus subtilis,Staphylococcus aureus.

ABSTRACT The antimicrobial activity of human β-defensin 3 (hBD-3) against multidrug-resistant clinical isolates of Staphylococcus aureus, Enterococcus faecium, Pseudomonas aeruginosa, Stenotrophomonas maltophilia, and Acinetobacter baumannii was evaluated. A fast bactericidal effect (within 20 min) against all bacterial strains tested was observed. The presence of 20% human serum abolished the bactericidal activity of hBD-3 against gram-negative strains and reduced the activity of the peptide against gram-positive strains.
