We analyzed surveillance cultures for vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus aureus (MRSA) collected during a multicenter trial to determine if three negative cultures collected at weekly intervals would predict clearance of VRE or MRSA from colonized patients. Seventy-two percent of VRE-colonized patients and 94% of MRSA-colonized patients were culture ...

Antibacterial activity of cold water and ethanolic crude extracts of leaves of Strophanthus wightianus Wall. ex Wight was evaluated against Gram negative bacteria(Escherichia coli, Pseudomonas fluorescens, Klebsiella pneumoniae and Enterobacter aerogenes) and Gram positive bacteria (Staphylococcus aureus, Methicillin resistant Staphylococcus aureus, Streptococcus mutans and Bacillus subtilis). ...

Staphylococcus lugdunensis is a skin commensal classified as a coagulase-negative Staphylococcus (CoNS). Though CoNS is typically associated with less aggressive clinical disease than Staphylococcus aureus, there is growing awareness that S. lugdunensis may be as virulent as S. aureus. The association between S. lugdunensis and infective endocarditis is well known, but few reports of native-joi...

background: many efforts have been done to find effective agents against resistant pathogens. cuminum cyminum l. (cumin) is an aromatic plant within the apiaceae family. it has a variety of purposes and demonstrates antimicrobial and antioxidant properties. this study evaluated the activity of c. cyminum extract and essential oil against bacterial isolates which cause urinary tract infection, i...

Viability of Staphylococcus xylosus isolated from artisanal sausages for application as starter cultures in meat products Viability of Staphylococcus xylosus strains AD1 and U5 isolated from natural fermented sausages was investigated as starter cultures in fermented sausages produced in the South Region of Brazil. The study demonstrated that the Staphylococcus xylosus strains AD1 and U5 showed...

In a recent article, Hussain et al. evaluated a commercial latex agglutination test (LA), the MRSA-Screen (Denka Seiken Co., Niigata, Japan), for rapid detection of penicillinbinding protein 2a (PBP2a) in mecA-positive and mecA-negative coagulase-negative staphylococci (CNS) (2). The sensitivity and specificity were 100 and 99.5% (2), respectively, although the MRSA-Screen was initially develop...

background and objective: the d-test is performed by placing clindamycin and erythromycin impregnated disks at a standard distance on the agar plate then looking for the flattening of inhibition zone around the clindamycin disk. a positive d-test indicates clindamycin inducible resistance and also predicts treatment failure possibility of this antibiotic in clinic. prevalence of staphylococcal ...
