OBJECTIVE The aim of the present study was to determine the in vitro maximum inhibitory dilution (MID) of two chlorhexidinebased oral mouthwashes (CHX): Noplak, Periogard, and one polyhexamethylene biguanide-based mouthwash (PHMB): Sanifill Premium against 28 field Staphylococcus aureus strains using the agar dilution method. MATERIALS AND METHODS For each product, decimal dilutions ranging f...

exploration of natural products with antitumoral effects such as etoposide, tenioposide, camptothecin and paclitaxel from conifers provoked us to do some research on anti-tumoral activity of iranian medicinal plants. ten different species of iranian conifers aerial parts were collected across the country. the relative potency of methanolic extract were investigated on the inhibition of topoisom...

Evaluation of an Agar Dilution Method for Identification of Extended-Spectrum Beta-Lactamase (ESBL)-Producing Klebsiella pneumoniae in the Environment

We read with interest the recently published paper by Piccolomini et al. (7). They evaluated three different methods to study the susceptibility of Helicobacter pylori to 20 antimicrobial agents. They found a very good correlation between E-test and agar dilution methods, as well as between broth microdilution and agar dilution. They recommended the E test as a reliable and alternative method f...
