pLm74 is the smallest known plasmid in Listeria monocytogenes. It confers resistance to the toxic divalent cation cadmium. It contains a 3.1-kb EcoRI fragment which hybridizes with the cadAC genes of plasmid pI258 of Staphylococcus aureus. When introduced into cadmium-sensitive L. monocytogenes or Bacillus subtilis strains, this fragment conferred cadmium resistance. The DNA sequence of the 3.1...

Ultrafine fiber membranes of polylactic acid (PLA) 8% (w/v) loaded with pink pepper essential oil (PPEO) in 10, 20 and 30% were produced evaluated for antimicrobial potential against the bacteria Escherichia coli, Salmonella enteritidis, Listeria monocytogenes Staphylococcus aureus. The applied simulated cream cheese packaging characterized by morphological, thermal, structural, wettability ana...

BACKGROUND AND AIMS Listeria monocytogenes and Staphylococcus aureus invade and multiply in THP-1 monocytes. Fluoroquinolones accumulate in these cells, but are less active against intracellular than extracellular forms of L. monocytogenes and S. aureus. We examined whether differentiation of THP-1 monocytes into adherent, macrophage-like cells increases fluoroquinolone uptake and activity. M...

The inhibition of Escherichia coli ATCC 25922 (E. coli), Staphylococcus aureus ATCC6538 (S. aureus), Salmonella Enteritidis 13076 Enteritidis), and Listeria monocytogenes DSM12464 (L. monocytogenes) is one the main aims food industry. This study was first in which use ultrasound microwave power were applied to optimize values bioactive components, amino acids, mineral compositions tangerine jui...

BAL0030543, BAL0030544, and BAL0030545 are dihydrophthalazine inhibitors with in vitro potency against gram-positive pathogens. The MIC(50)s for methicillin (meticillin)-sensitive Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, hetero-vancomycin-resistant Staphylococcus aureus, and vancomycin-resistant Staphylococcus aureus (VISA) range from 0.015 to 0.25 microg/ml (MIC(90)s...

The in vitro activities of ABT-773, erythromycin, clarithromycin, and azithromycin were compared. ABT-773 was the most active compound against macrolide-susceptible Streptococcus pneumoniae, Streptococcus pyogenes, Staphylococcus aureus, Staphylococcus epidermidis, Listeria monocytogenes, and Enterococcus spp. and multidrug-resistant Streptococcus pneumoniae. It also had good activity against g...
