Bacterial movement inside the cytoplasm is a major virulence factor in that it is necessary for efficient colonization of the infected tissues. Molecules from both the host and the pathogen present possible sites of pharmacologic intervention. Because locomoting Listeria and Shigella mimic the activated state of the leading edge of nonmuscle cells, these pathogens are powerful tools for dissecting...
The presence of class 1 integrons was investigated in 156 epidemiologically unrelated Salmonella Typhimurium isolates. Of these 156 isolates, 70 were of definitive phage type DT104 and 86 were strains of various phage type, RDNC and untypable, designated here as non-DT104 strains. Intégrons were found in 47 of DT104 isolates (67.1%), while in all strains with characteristic pentaresistance (R-type...
Mutagenic pollution of environment is a global and important problem. This includes marine environment. Although many mutagenicity assays have been developed, there are specific problems with testing marine water and sediments for mutagenic contamination. One of them is the fact that most of genetically modified strains used in commonly available microbiological mutagenicity assays, like Escherichia...
The most characteristic finding in non-typhoid salmonella (NTS) infection is acute food related outbreaks of gastroenteritis, which is usually benign and self-limiting. However, more serious extraintestinal findings, such as bacteraemia and focal infections localized to any organ may appear. The objective of this paper is to describe the most important characteristic of the extraintestinal infections...
We report that using the zwitterionic detergent Zwittergent Z 3-14® to isolate outer membrane proteins (OMPs) from Salmonella O48 is suitable for their separation by two-dimensional electrophoresis (2-DE) in a capillary tube system. Sample preparation is a very crucial step for any bacterial proteomic study. Some modifications were introduced to the 2-DE protocol suggested by O'Farrell and BioRad,...
The diagnostic assessment of water sanitary state is based mainly on the cultivation of bacteria retained on membrane filters. However classical microbiology methods have a lot of disadvantages. More and more frequently, rapid detection and identification of pathogens present in water is based on molecular biology techniques. The aim of this study was to determine the effectiveness and usefulness...
