This review examined the use of green tea (Camellia sinensis) in the diets of poultry. Research findings were obtained from various recent studies, where much attention was focused on the role of green tea in the promotion of both animal and human health. The review involved some of the currently available information about green tea, pertaining to its chemical composition, anticoccidial and an...

A contingency of observed antimicrobial activities measured for several compounds vs. a series of bacteria was analyzed. A factor analysis revealed the existence of a certain probability distribution function of the antimicrobial activity. A quantitative structure-activity relationship analysis for the overall antimicrobial ability was conducted using the population statistics associated with i...

Objectives: The emergence of carbapenem-resistant Enterobacteriaceae, especially Klebsiella pneumoniae, has become a major concern in clinic settings. Combination therapy is gaining momentum to counter the secondary resistance and potential suboptimal efficacy of monotherapy. The aim of this study was to evaluate the bactericidal effect of fosfomycin (FM), amikacin (AMK), or colistin (COL) alon...

The purpose of this study was to examine the biofilm removing and antimicrobial effects of microbubbled tap water and other functional water. The biofilm removal test showed that the activity of microbubbled tap water against the biofilm of Candida albicans and Streptococcus mutans was significantly higher than that of ordinary tap water (p<0.01). When the antimicrobial activities of two types ...

Streptomycetes group was studied in twenty-three soil samples of western region. The highest density of this group was found in 3 soil samples collected from AI-Madinah Al-Munawwarah. Six Streptomyces series were observed. Gray series represented the most dominant isolates. The highest antimicrobial activity was recorded in the case of gray and red series. Streptomyces MR13 (red series) had a b...

The antimicrobial effect of L-lactate was much greater than that of D-lactate over a range of concentrations for Escherichia coli O157 and non-O157 strains. Despite this, the intracellular pHs and membrane potentials of L-lactate- and D-lactate-treated cells were similar, suggesting that these factors are not involved in the antimicrobial action of L-lactate.

To assess the antimicrobial effect of a commercial steam-vacuuming system newly implemented after slaughtering, 105 cattle carcasses were examined for total viable counts (TVC) at four different areas. Before steam vacuuming, mean TVC of the excision samples were comparable at the perineal area and brisket (3.0-3.1 log CFU cm-2) or the hind leg and shoulder (2.6-2.7 log CFU cm-2). Steam vacuumi...

Graphene oxide-zinc oxide hybrid nanostructures were synthesized and they demonstrated significant and promising antimicrobial activity on pathogenic bacteria. The combination of graphene oxide with zinc oxide nanorods showed an impressive antibacterial effect under intense scrutiny as compared with individual graphene oxide or zinc oxide nanomaterials. The characterization and investigation of...

AIM The purpose of this study was to test a new root canal sealer (Epiphany) and 5 other root canal sealers (Diaket, Endomethasone, AH 26, Sealapex, Sultan) for their antimicrobial effect on Enterococcus faecalis. MATERIALS AND METHODS The antimicrobial effect of 6 root canal sealers was tested by the agar diffusion method. The freshly mixed sealers were placed in prepared wells of agar plate...

The aim of this study was to investigate the antimicrobial effect of chitooligosaccharides prepared by chitosanase from Pseudomonas CUY8. Antimicrobial activities of different degrees of deacetylation (DD) and polymerization (DP) of chitooligosaccharides against various species of bacteria and fungi were measured. The antimicrobial effects of chitooligosaccharides compared with chitosan and chi...
