Characterization of Clostridium tyrobutyricum Strains Using Three Different Typing Techniques

Comparison of three different techniques in parotid gland tumors using three dimensional conformal radiation therapy

Introduction: Background: Radiotherapy of parotid tumors is achieved by different radiotherapy techniques. So they deliver the dose to organs at risk such as contralateral parotid, temporal lobe & spinal cord. The consequences of high dose to OARs are xerostomia, Temporal lobe necrosis and loss of hearing. Purpose: The aim of this study was to compare different treatment tech...

Action of egg white lysozyme on Clostridium tyrobutyricum.

A 500-U ml-1 portion of egg white lysozyme was able to kill 99% of 5 X 10(5) resting vegetative cells of Clostridium tyrobutyricum within 24 h of incubation at 25 degrees C. Spores were completely resistant to lysozyme. Proliferating vegetative cells were severely inhibited, although lysozyme-resistant cells developed in growing cultures in the presence of lysozyme. Whereas early stages of spor...

Comparative study of five different DNA fingerprint techniques for molecular typing of Streptococcus pneumoniae strains.

The aim of this study was to identify the strengths and weaknesses of five DNA fingerprint methods for epidemiological typing of Streptococcus pneumoniae. We investigated the usefulness of (i) ribotyping, (ii) BOX fingerprinting with the BOX repetitive sequence of S. pneumoniae as a DNA probe, (iii) PCR fingerprinting with a primer homologous to the enterobacterial repetitive intergenic consens...
