Effects of streptomyces rochi Biosurfactants on Pathogenic Staphylococcus aureus and Pseudomonas aeruginosa

Inhibitory effects of ozonated grape seed oil on Staphylococcus aureus and Pseudomonas aeruginosa

Pseudomonas aeruginosa, Staphylococcus aureus, and Fluoroquinolone Use

Few long-term multicenter investigations have evaluated the relationships between aggregate antimicrobial drug use in hospitals and bacterial resistance. We measured fluoroquinolone use from 1999 through 2003 in a network of US hospitals. The percentages of fluoroquinolone-resistant Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus (MRSA) were obtained from yearly antibiogr...

Effectiveness of honey on Staphylococcus aureus and Pseudomonas aeruginosa biofilms.

OBJECTIVES Biofilms formed by Pseudomonas aeruginosa (PA) and Staphylococcus aureus (SA) have been shown to be an important factor in the pathophysiology of chronic rhinosinusitis (CRS). As well, honey has been used as an effective topical antimicrobial agent for years. Our objective is to determine the in vitro effect of honey against biofilms produced by PA and SA. STUDY DESIGN In vitro tes...

In vitro Evaluation of Methylxanthines and Some Antibiotics: Interaction against Staphylococcus aureus and Pseudomonas aeruginosa

Background: The development of resistance to antimicrobial agents is a major problem in chemotherapy. Finding agents which potentiate antimicrobial activity could be favorable. There are some reports that methylxanthines changed the inhibitory effect of antibacterial agents. Thus, possible synergistic effect of methylxanthines, aminophylline and caffeine on some antibiotics, carbenicillin, ceft...

Effects of Cream Containing Rhamnolipid Microbial Surfactants from Pseudomonas aeruginosa MR01 on Growth Inhibition of Staphylococcus aureus

Background and purpose: Dramatic increase in antibiotic-resistant bacteria highlights the need for new compounds with more effective antibacterial properties and biotechnology could be useful in producing these metabolites. The present study aimed at investigating the effects of rhamnolipid microbial surfactants in a cream-based formulation on growth inhibition of Staphylococcus aureus using in...
