Background: Mentha piperita L. essential oils have different antibacterial activity. In the present study, we investigated the effect of &gamma–irradiation on the antibacterial activities of Mentha piperita L. essential oils in vitro and in vivo systems. Materials and Methods: The aerial parts of peppermint were irradiated in a cobalt60 source with 0, 10 and 25 kGy absorbed doses. Then, t...

BACKGROUND Flowers of Punica granatum L. (Punicaceae) var. pleniflora, known as "Golnar" in Iranian traditional medicine have been used for the prevention and treatment of foodborne diseases. In this study, antibacterial activities of ethanol extract of Golnar and its fractions were scientifically evaluated against bacteria causing foodborne diseases including Staphylococcus aureus, Bacillus ce...

Quinolone resistance in clinical isolates of Campylobacter jejuni in Sweden increased more than 20-fold at the beginning of the 1990s. Resistance to 125 microgram of ciprofloxacin per ml in clinical isolates was associated with chromosomal mutations in C. jejuni leading to a Thr-86-Ile substitution in the gyrA product and a Arg-139-Gln substitution in the parC product.

Levofloxacin carboxamides with certain amino acids were prepared through an amide linkage to the acid (glycine, histidine, or serine). These subjected in silico molecular docking evaluation on
 
 DNA gyrase predict their antibacterial activity using GOLD suite. The binding affinities very significant and encouraged synthesis of suggested for intensive evaluation. also Swiss ADME softw...
