| proteus mirabilis isolates of different origins do not show correlation with virulence attributes and can colonize the urinary tract of mice. | proteus mirabilis has been described as an aetiological agent in a wide range of infections, playing an important role in urinary tract infections (utis). in this study, a collection of p. mirabilis isolates obtained from clinical and non-clinical sources was analysed in order to determine a possible correlation between origin, virulence factors and in vivo infectivity. isolates were characterized in vitro, assessing several virulence properties that had been previously associated with p. mirabi ... | 2006 | 16804188 |
| mapping bacterial surface population physiology in real-time: infrared spectroscopy of proteus mirabilis swarm colonies. | we mapped the space-time distribution of stationary and swarmer cells within a growing proteus mirabilis colony by infrared (ir) microspectroscopy. colony mapping was performed at different positions between the inoculum and the periphery with a discrete microscope-mounted ir sensor, while continuous monitoring at a fixed location over time used an optical fiber based ir-attenuated total reflection (atr) sensor, or "optrode." phenotypes within a single p. mirabilis population relied on identific ... | 2006 | 16808858 |

| colonization of sitka spruce stumps by decay-causing hymenomycetes in paired inoculations. | sitka spruce stumps were inoculated with decay fungi using colonized sawdust or dowel inoculum to investigate colonization in paired combinations. estimates of domain sizes were made in the top 15cm of stump after 13-14 or 21-23 months with sawdust or dowel inoculations, respectively. none of the co-inoculated species prevented colonization by heterobasidion annosum; sapwood colonization by resinicium bicolor may limit growth of h. annosum colonies out of heartwood, reducing the incidence of dis ... | 2006 | 16814536 |
| characterisation of prototype nurmi cultures using culture-based microbiological techniques and pcr-dgge. | undefined nurmi-type cultures (ntcs) have been used successfully to prevent salmonella colonisation in poultry for decades. such cultures are derived from the caecal contents of specific-pathogen-free birds and are administered via drinking water or spray application onto eggs in the hatchery. these cultures consist of many non-culturable and obligately anaerobic bacteria. due to their undefined nature it is difficult to obtain approval from regulatory agencies to use these preparations as direc ... | 2006 | 16814892 |
