Escherichia coli is being one of the common microbial flora of gastrointestinal and respiratory tracts of poultry but may become pathogenic to both. Antibiotic treatment is considered the most important issue that promotes the emergence, selection and deploying of antibiotic-resistant microorganisms in veterinary medicine. With the increase of resistant to antibiotics, many researchers have tri...

Licorice (Glycyrrhiza glabra L.) is an important medicinal plant. In this study, the antimicrobial activities of ethanolic and aqueous extracts from licorice leaves were studied compared to root extracts activities. Bacillus subtilis, Enterococcus faecalis, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli, and Candida albicans were used as test organisms...

Abstract In the present study, nanoparticles of copper and copper oxides were synthesized and their antibacterial activity was evaluated and compared with silver nanoparticles. The nanoparticles were synthesized using facile chemical reactions, and then characterized using field emission scanning microscopy. The nanoparticles were stable for at least two weeks. The...

Exposure of bacterial cells to honey inhibits their growth and may cause cell death. Our previous studies showed a cause-effect relationship between hydroxyl radical generated from honey hydrogen peroxide and growth arrest. Here we explored the role of hydroxyl radicals as inducers of bacterial cells death. The bactericidal effect of ·OH on antibiotic-resistant clinical isolates of MRSA and VRE...

This study evaluated the antimicrobial, antioxidant and toxicity activity of essential oils (EOs) Hymenaea courbaril L. var. bark Syzygium cumini (L.) Skeels leaves. The EOs were extracted by hydrodistillation chemically characterized gas chromatography coupled to mass spectrometry (GC/MS). ABTS DPPH assay used evaluate activity. For assay, lethality was against Artemia salina Leach. antimicrob...

Netilmicin (SCH 20569), a new broad-spectrum aminoglycoside derived from sisomicin, was compared with gentamicin in the therapy of experimental Escherichia coli meningitis in rabbits. Meningitis was produced in 48 animals by the intracisternal inoculation of 10(5)E. coli colony-forming units. The minimum bactericidal concentration was 2 mug/ml against the test strain for both gentamicin and net...
