Observation of Salmonella enterica subsp. enterica serovar Typhimurium LB5010 and the stbC mutant strain grown on solid agar. (a) Salmonella enterica subsp. enterica serovar Typhimurium LB5010 grown on LB agar at 37°C for 16 h did not produce fimbrial appendages. (b) The Salmonella enterica subsp. enterica serovar Typhimurium stbC mutant grown on LB agar at 37°C for 16 h exhibited flagella structures (arrowhead) but no fimbrial appendages were observed (3,000x). Bacterial cells were negatively stained with 2% of phosphotungstic acid (20,000x).
