Detection of extended-spectrum beta-lactamases (ESBLs) in clinical isolates of Klebsiella pneumoniae using the ESBL NDP test and flow cytometric assay in comparison to the standard disc diffusion

This study was undertaken to evaluate the comparison among three different assays: extended-spectrum beta-lactamases (ESBL) Nordmann/ Dortet/ Poirel (NDP) test, flow cytometric assay and disc diffusion method for the detection of ESBL production. Sixty clinical isolates of Klebsiella pneumoniae were isolated from patients’ clinical samples admitted to Suez-Canal University Hospital, Ismailia Governorate. The...

Physicochemical and in vitro antimicrobial activity of the oils and soap of the seed and peel of Citrus sinensis

Citrus sinensis seed and peel oils were extracted by solvent extraction using n-hexane, after air drying and grinding. Soaps were formed by saponification methods. Fatty acid composition of the oil samples were analyzed using Gas Chromatograph-Flame Ionization Detector (GC-FID). Physicochemical properties of the oils and soaps were determined following standard methods. Antimicrobial activities were assessed by the agar...
