Carvone is one of the naturally occurring monoterpenes, the largest class of secondary metabolites in plants, and exists in two enantiomers, R-carvone (R-car) and S-car. The objective of this study was to investigate the antimicrobial activity of R-car and S-car with gentamicin (GET) against methicillin-resistant Staphylococcus aureus (MRSA). MRSA is a major human pathogen that causes serious p...

AIMS To investigate the epidemiological and clinical aspects of MRSA among inpatients and outpatients presenting to hospital. METHODS Analysis of demographic, epidemiological, and clinical data collected on 385 children first identified as having MRSA between January 1998 and December 2003 in a 250 bed English children's hospital. RESULTS There were 267 inpatients and 118 outpatients. The n...

Objectives: Tigecycline is a new glycylcycline group antibiotic with broad-spectrum activity. In the present study we report on in vitro activity of tigecycline as well as the comparator antimicrobials linezolid and quinupristin/dalfopristin against methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin resistant Staphylococcus aureus (MRSA) strains isolated from burn wounds in Tr...

The findings of clinical and in vitro research support the theory that infective endocarditis (IE)-causing bacteria form biofilms and that biofilms negatively affect treatment outcomes. The purpose of the present study was to quantify the biofilm formation of methicillin (meticillin)-resistant Staphylococcus aureus (MRSA) isolates obtained from patients with IE and to evaluate the in vitro acti...

We examined the activity of CB-181963, a novel cephalosporin, against methicillin-resistant Staphylococcus aureus (MRSA) (n = 200), methicillin-susceptible S. aureus (MSSA) (n = 50), glycopeptide-intermediate Staphylococcus species (GISS) (n = 47), and VRSA (n = 2) isolates. CB-181963 exhibited MIC profiles similar to those of linezolid against MRSA and GISS; however, activity against MSSA was ...

We asked whether beta-lactamase inhibitors (BLIs) increased the activity of daptomycin (DAP) against methicillin-resistant Staphylococcus aureus (MRSA), the peptide antibiotic colistin (COL) against the emerging Gram-negative nosocomial pathogen Acinetobacter baumannii, and the human host defense peptide cathelicidin LL37 against either pathogen. DAP and LL37 kill curves were performed with or ...

introduction: aloe vera compounds have inhibitory activity on fungi, bacteria, and viruses. this study examines the antibacterial activity of a. vera purified extracts including gel, boiled skin, boiled gel, and distilled extract against pathogenic bacteria, staphylococcus aureus, methicillin-resistant s. aureus (mrsa), klebsiella pneumonia and pseudomonas aeruginosa were elucidated. method: th...

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is an organism causing significant mortality and morbidity with nosocomial infections. Ceftaroline is a new cephalosporin antibiotic that has activity against MRSA. In the USA, this antibiotic has not been approved for use in pneumonia caused by MRSA. Objectives: To review the use of ceftaroline in MRSA pneumonia in a US hospital an...

Based on ethnopharmacological information, four different varieties of seeds were obtained from authentic seed suppliers. Ethanol, methanol, acetone, chloroform and petroleum ether seed extracts were assessed for antibacterial activity against wound isolates of Multi Drug Resistant Methicillin Resistant Staphylococcus aureus (MDR-MRSA). Ethanol, methanol and acetone extracts of Moringa oleifera...

Staphylococcus aureus and coagulase-negative staphylococci (CoNS) are responsible for a wide variety of human infections. The investigational antibacterial Debio1450 (previously AFN-1720), a prodrug of Debio1452 (previously AFN-1252), specifically targets staphylococci without significant activity against other Gram-positive or Gram-negative species. Debio1452 inhibits FabI, an enzyme critical ...
