We compared human and bovine isolates of Salmonella enterica using antimicrobial-drug resistance profiles and pulsed-field gel electrophoresis. From 2000 through 2006, we observed an increase in a novel multidrug-resistant clone of S. Typhimurium with no recognized phage type. This clone may represent an emerging epidemic strain in the Pacific Northwest.

Phosphodiesterase enzymes (PDEs) are responsible for the adjustment of cyclic nucleotide levels. Alterations in PDE expressions in different tissues cause conflicts between functional and clinical effects of PDE inhibitors. Therefore, the aim of this study was to investigate the gene and protein expressions and the functional role of PDEs in atrium and ventricle of rat heart The expressions of PDEs were examined in cardiac intact tissues and enzymatically isolated cells. The effects of PDE1-5 inhibitors (vi...
Investigation of antioxidant and antimicrobial effects of Plantago major leaves
Kaya, Özge; Çoruh, Nursen; Sağdıçoğlu Celep, A. Gülçin; Department of Biochemistry (2011)
This study was designed to investigate Plantago major leaves, which is widely used in ethnobotanical uses in Turkey as is the case in all over the world, for their antioxidant capacities and antimicrobial effect on two gram-positive and two gramnegative bacteria. Extracts of P. major leaves prepared in the methanol and fraction samples were collected in solvents in increasing polarity, from non-polar to polar, to separate bioactive compound in crude extract. Antioxidant capacities of the crude extracts and ...

All rights reserved.The purpose of this study is to synthesize and characterize the mesoporous nanostructure of Hydroxyapatite (HA), evaluate the impact of the addition of sulphate ions (SO42-) on the microstructure properties of HA, and assess the ability of the prepared materials to be used as a carrier for Bovine serum albumin (BSA) protein. This study successfully synthesized 0.07 mole of SO42- substituted HA using the reflux microwave-assisted wet precipitation method and fully characterized it using m...
Salmonella enterica Serotype 4,5,12:i:-, an Emerging Salmonella Serotype That Represents Multiple Distinct Clones
Soyer, Yeşim; Davis, M. A.; Maurer, J.; McDonough, P. L.; Schoonmaker-Bopp, D. J.; Dumas, N. B.; Root, T.; Warnick, L. D.; Groehn, Y. T.; Wiedmann, M. (American Society for Microbiology, 2009-11-01)
The prevalence, among human clinical cases, of Salmonella enterica serotype 4,5,12: i:-, a serotype antigenically similar to Salmonella enterica serotype Typhimurium but lacking second-phase flagellar antigens, has increased considerably over the last 10 years. To probe the evolution and ecology of this emerging serotype, we characterized 190 Salmonella isolates initially classified as Salmonella serotypes 4,5,12: i:- (n = 90) and Typhimurium (n = 100) and obtained from various sources in the United States ...
