Family Cupressaceae is the largest coniferous plant family. Essential oils of many species belonging to family Cupressaceae are known to have several biological activities specially antimicrobial activity. The essential oils from aerial parts of Calocedrus decurrens Torr., Cupressus sempervirens stricta L. and Tetraclinis articulata (Vahl) Mast. were prepared by hydrodistillation. The chemical ...
Background & Aims: The natural compounds have received more attention due to their lower side effects and better biodegradation compared to antibiotics. The purpose of this study was to investigate the antibacterial and antioxidant effects of leaf and skin essential oil of Citrus Grandis on some human pathogenic bacteria. Materials & Methods: The leaf and skin of Citrus Grandis were collected ...
morphological and bactericidal effects of amikacin, meropenem and imipenem on pseudomonas aeruginosa
conclusions induction of coccoid form of p. aeruginosa may be one of the important reasons for antibiotic treatment failure; therefore, prescribed dose of antibiotics should be carefully managed to prevent increasing antibiotic resistance and coccoid bacteria induction. results all used antibiotics at sub mic concentration had capability to induce coccoid bacteria. the highest rate of induced c...
The action and interaction of benzylpenicillin and gentamicin on Streptococcus faecalis was studied using mainly turbidimetric methods. The minimum antibacterial concentration (MAC) of each antibiotic lay considerably below the conventionally determined minimum inhibitory concentration, and levels of the two agents exceeding the MAC were necessary in order to obtain a synergic interaction. Evid...
The aim of this chapter is to evaluate the contribution of antimicrobial therapeutic drug monitoring (TDM) to adjust dosing regimens in achieving control of infections using pharmacokinetics (PK) and pharmacodynamics (PD) to define the antimicrobial exposures that are necessary to maximise bactericidal activity and to inhibit bacterial growth. Robustness data exist for some antimicrobial agents...
Agaricus bisporus mushrooms are well known for their nutritional and medicinal values. A. bisporus is a source of protein (about 40% on a dry basis), ergosterol, several minerals, carbohydrate, and fat. The present study was conducted to investigate the effect of A. bisporus S-II extracts on human pathogenic bacteria in-vitro condition. Totally, thre...
SMAP29, an ovine cathelicidin, was systematically altered to create a family of 23 related peptides for MIC and minimum bactericidal concentration determinations. SMAP28, SMAP29, and a derivative of SMAP29 called ovispirin were all antimicrobial. However, many congeners of SMAP29 and ovispirin were not as active as the parent molecules. With immunoelectron microscopy, SMAP29 was seen on membran...
The in vitro activities of HMR 3647, roxithromycin, erythromycin, and azithromycin against 19 strains of Chlamydia pneumoniae were tested. The MIC at which 90% of the isolates are inhibited and the minimum bactericidal concentration at which 90% of the isolates are killed of HMR 3647 were 0.25 microgram/ml (range, 0.015 to 2 micrograms/ml). Nine recently obtained clinical isolates from children...
