Flow cytometry is a rapid method to quantitate live and dead bacteria in a sample.1-4 It can be used to measure the efficacy of antimicrobial compounds by exposing organisms to the disinfectant and subsequently staining with permeant and impermeant DNA dyes. Test organism viability, measured using a 30-minute flow cytometry assay, showed comparable sensitivity with a standard 48-hour plate coun...

BACKGROUND & OBJECTIVE Clinical laboratories need to develop quick screening methods for detection of extended spectrum beta-lactamase (ESBL) producing strains, so that the appropriate medication can be started without delay. In this study, we report the screening sensitivity of four representative antimicrobial agents i.e., cefpodoxime, cefotaxime, ceftazidime and aztreonam, commonly used for ...

The present investigation was aimed to evaluate the broad spectrum antimicrobial and phytochemical analysis of the alcoholic and aqueous extracts derived from the flowers of Alangium salviifolium. Aqueous and ethanolic extracts were prepared and tested on multiple drug resistant Gram-positive (Staphylococcus aureus, Enterococci and Staphylococcus epidermidis) and Gramnegative(Citrobacter, Pseud...

introduction: methicillin-resistant staphylococcus aureus (mrsa) can cause serious and life-threatening hospital- and community-acquired infections. colonized and infected patients represent the most important reservoir of mrsa in health care facilities. therefore, in this study, mrsa isolates collected from shohada hospital in tabriz were evaluated for the frequency of meca gene and their anti...

Background & Aim: By increasing resistance of fish pathogens to chemical drugs, using herbal plants with antimicrobial properties is necessary.In this study, the composition of the essential oil and antimicrobial activity of aerial parts of Achillea wilhelmsii C.Koch growing wild in Zagross mountain (Southwest of Iran) was analyzed against common bacterial and fungal pathogens of fish....
