Background Enterococci are opportunistic pathogens causing severe urinary tract infections, surgical wound infections, bacteremia and bacterial endocarditis. Aggregation substance (asa1), hemolysin/ cytolysin (cylA), gelatinase (gelE), enterococcal surface protein (esp), hyaluronidase (hyl) and biofilm formation are the major virulence determinants responsible for pathogenicity of enterococci. ...

Enterococci, as the major cause of nosocomial infections, have been shown to have an increase in drug resistance during the past two decades. TheEntrococcalemergence of Vancomycin-resistant is very important nowadays. The purpose of this study was to determine the drug sensitivity of Enterococcus faecalis and Enterococcus faecium species against Vancomycin, Tetracycline, Gentamicin, Erythromyci...

The novel heterocyclization of 5-(2-aminophenyl)-1H-tetrazole with potassium ethylxanthogenate or carbon disulfide was proposed. The potassium salt of the tetrazolo[1,5-c]quinazoline-5-thione was subsequently modified by alkylation with proper halogen derivatives to (tetrazolo[1,5-c]quinazolin-5-ylthio)alkyls, N,N-dialkylethylamines, 1-aryl-2-ethanones, 1-(alkyl)aryl-2-ethanols, carboxylic acid...

The condensation reaction of 5-(4-aminophenyl)-4-phenyl-1,2,4-triazole-3-thione with salicylaldehyde, 4-hydroxybenzaldehyde, 5-chlorosalicylaldehyde, 5-bromosalicylaldehyde, 2-nitrobenzaldehyde, 3-nitrobenzaldehyde, 4-nitrobenzaldehyde and 4-methoxybenzaldehyde in methanol results in series of new Schiff bases. The structure of Schiff bases were confirmed by 1H NMR, 13C NMR, IR and mass spectro...

objective(s) malva sylvestris l. (malvaceae), an annual plant, has been already commonly used as a medicinal plant in iran. in the present work, we evaluate some bioactivities of the plant extracts. materials and methods the aired-dried plant flowers and leaves were extracted by soxhlet apparatus with n-hexane, dichloromethane and methanol. the antimicrobial, cytotoxic, and phytotoxic of the pl...
