vertebral osteomyelitis, or spondylodiscitis, is a rare disease with increasing prevalence in recent years due to a greater number of spinal surgical procedures, nosocomial bacteraemia, an aging population and intravenous drug addiction. haematogenous infection is the most common cause of spondylodiscitis. we report a 47-year-old man diagnosed with escherichia coli spondylodiscitis. the patient...

The objective of this study was to evaluate the antibacterial activity of various extracts of whole plant of Borreria hispida (Linn). The extract was prepared from the whole plant of Borreria hispida by hot continuous percolation method in Soxhlet apparatus with various solvents (Pet. Ether, ethyl acetate, Methanol). All the extracts of Borreria hispida were tested for antibacterial efficacy ag...

Biyopolimerlerin ambalaj malzemesi olarak kullanımı düşük mekanik, termal ve bariyer özelliklere sahip olması nedeniyle kısıtlıdır. Bu kısıtlama biyopolimerlere dolgu malzemeleri eklenerek giderilebilmektedir. çalışmada saf polikaprolakton (PCL) % 0,5 w/v oranında halloysit (HAL) karıştırılarak, PCL/HAL filmler çözelti döküm yöntemiyle hazırlanmıştır. filmlere yapısal (ATR-FTIR XRD), (TGA) meka...

From acid-disintegrated flagellar hooks of Salmonella SJ25 an immunochemically pure preparation of hook protein was obtained by column chromatography. The molecular weight of the protein determined by sodium dodecyl sulfate-gel electrophoresis was 43,000, whereas that of SJ25 flagellin was 56,000. The amino-terminal residue of the hook protein was determined to be seryl. The amino acid composit...

Shiga toxin-producing Escheria coli (STEC) strains are virulent agents responsible for thousands of illnesses in the United States [1]. The most common and notorious STEC serotype is O157:H7 but other serotypes, like O104:H4 responsible for May 2011 HUS outbreak in Germany [2], are responsible for one third of STEC related illness. Beginning on June of 2012 the U.S. Department of Agriculture st...

The effect of shifting zygotes from a rich medium into a poor medium (shift-down) on the frequency of recombination has been examined; our results suggest that protein syntheses other than those required for growth may be involved. Experiments with chloramphenicol support this notion, and further suggest that there is a competition between genetic integration and degradation in the recipient ce...
