“…In addition, results of susceptibility testing vary when different methods are used. Results from disk diffusion methods may not be reliable, so broth reference quality microdilution tests should be performed when possible (1,9).…”

Limited data are available on Chryseobacterium spp. leading to an evaluation of the patient demographics and susceptibility patterns for Chryseobacterium spp. collected in the first 5 years of the SENTRY Antimicrobial Surveillance Program (1997 to 2001). Fifty isolates (24 Chryseobacterium meningosepticum, 20 Chryseobacterium indologenes, two Chryseobacterium gleum, and 4 Chryseobacterium spp. isolates) were collected. The highest Chryseobacterium prevalence was detected among the elderly. The most active antimicrobials were the newer quinolones (garenoxacin, gatifloxacin, and levofloxacin, each with a MIC at which 90 percent of the isolates are inhibited [MIC 90 ] of 1 g/ml and 98.0% susceptibility) followed by rifampin (MIC 90 , 2 g/ml and 85.7% susceptibility). Trimethoprim-sulfamethoxazole, ciprofloxacin, and piperacillin-tazobactam also showed reasonable activity; vancomycin showed poor potency.

“…Disc diffusion method for filamentous fungi tested by using approved standard method (M38-A) developed [18] for evaluating the susceptibilities of filamentous fungi to antifungal agents. Disc diffusion method for yeasts developed by using approved standard method (M44-P) [19]. Plates inoculated with filamentous fungi as Aspergillus flavus at 25°C for 48 hours; Gram (+) bacteria as Staphylococcus aureus, Bacillus subtilis; Gram (-) bacteria as Escherichia coli, Pseudomonas aeuroginosa they were incubated at 35-37°C for 24-48 hours and yeast as Candida albicans incubated at 30°C for 24-48 hours and, then the diameters of the inhibition zones were measured in millimetres [20].…”

Green Synthesis of Novel 5-Arylazo-2-[(2S, 3S, 4R, 5R)-3, 4, 5-trihydroxy-6-(hydroxymethyl) tetrahydro-2H-pyran-2-yloxy]-4, 6-dimethyl 3-nicotinonitrile IntroductionPyridine nucleus is one of the most interesting nucleus in organic synthesis. Many uses of pyridines derivatives were investigated in the recent decades especially fluorinated derivatives. One of the recent researches discovered that high tuberculostearic activity of pyridine was observed [1,2].Also from the amazing character of some pyridine is its high fluorescence activities which was used as molecular sensor of picric acid [3].It has been of great importance in the exploring of some novel antimicrobial compounds in veterinary as well as human medicine worldwide. Genetic mutation and acquisition of mobile drug resistance genes of microorganisms is a very great resistance and barrier in treating animal and human patients with infectious diseases [4,5]. The importance of the synthesis of novel derivatives of pyridine nucleosides due to their potential use to treat various diseases, such as hepatitis cancer and microbial infections [6][7][8][9][10].Fluorinated derivatives of pyridines are of high significance in pharmaceutical and medicinal chemistry [11]. Synthesis of poly substituted fluroarylazopyridone by using green protocol is of great effect in synthetic chemistry and also in pharmaceutical chemistry [12]. The presence of fluorine atoms in the molecule can change its lipophilicity, which also affect and change the rate of transportation through lipid membranes [13]. Achievement of green and sustainable chemistry protocol instead of classical methods synthetic chemistry nowadays is of high interest, especially in synthesis of some novel Fluro arylazo pyridine derivatives (1a-e) and their nucleosides (3a-e). Methodology ChemistryGeneral coupling procedures of synthesis of Acetylated -arylazo-2-[(2S, 3S, 4R, 5R)-3, 4, 5-trihydroxy-6-(hydroxymethyl) tetrahydro-2H-pyran-2-yloxy]-4,6dimethylnicotinonitrile AbstractPyridine derivatives played important roles in the last decade in to approach many and different functionalities, especially as antitumor, antibacterial, anti-fungal, and many of pharmacological activities. Novel compounds of 5-Arylazo-2-[(substituted)-3,4,5-trihydroxy-6-(hydroxymethyl) tetrahydro-2H-pyran-2-yloxy]-4,6dimethyl nicotine nitrile, (3a-e), generally called (Fluro arylazo pyridine glucosides) were synthesised via green protocol, microwave scheme 3, and the compounds were investigated on the basis of spectroscopic data (FT-IR, 1D, 13 C), and antibacterial and antifungal studies had been applied. Microwave method: A mixture of 2(1H)-pyridines (1a-e) (10 mmol) and 1″,2″,3″,4″,6″-penta-O-acetyl-α-D-glucopyranose (11 mmol, 4.29 g) where be dissolved in a mixture of methylene chloride/methanol (80/20) then silica gel (200-400 mesh) where be added after that the excess solvent was removed by evaporation. The dried residue was transferred into a 10 mL vial and subjected to microwave irradiation for 2-3 minutes using CEM Microwave syst...

“…On the contrary, aminoglycosides, other ␤-lactams, chloramphenicol, linezolid, and glycopeptides are not appropriate for treating infections due to this organism (8). Clinical microbiologists have two additional problems to resolve: (i) susceptibility disk diffusion testing is inaccurate for chryseobacteria (1,3) and (ii) the MIC breakpoints for these organisms have not been established by the NCCLS (11).…”
