Trophic cooperation promotes bacterial survival of 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...

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...

Antibacterial performance of MELITININ - BMAP27 hybrid peptide against Staphylococcus aureus and Pseudomonas aeruginosa strains

Abstract Background and purpose: Multiple drug-resistant (MDR) bacterial strains have spread in different parts of hospitals. The aim of this study was to design and synthesize an effective hybrid peptide by combining different parts of two peptides to achieve the highest antibacterial activity and its inhibitory effect against Staphylococcus aureus and Pseudomonas aeruginosa strains. Materia...

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

Accumulation of 99mTc-ciprofloxacin in Staphylococcus aureus and Pseudomonas aeruginosa.

The use of radiopharmaceuticals for the diagnosis of infection is increasing due to their ability to distinguish between septic and aseptic inflammation. The aim of this study was to analyze the intracellular accumulation of technetium-99m-ciprofloxacin in strains of Staphylococcus aureus and Pseudomonas aeruginosa harboring an overexpression of NorA and MexAB-OprM, respectively.
