Autotransporter MisL of Salmonella enterica serotype Typhimurium facilitates bacterial aggregation and biofilm formation

Serotype Typhimurium enterica Salmonella Autotransporter Protein of MarT Activates Expression of the MisL

Brominated furanones inhibit biofilm formation by Salmonella enterica serovar Typhimurium.

Salmonella enterica serovar Typhimurium is a main cause of bacterial food-borne diseases. As Salmonella can form biofilms in which it is better protected against antimicrobial agents on a wide diversity of surfaces, it is of interest to explore ways to inhibit biofilm formation. Brominated furanones, originally extracted from the marine alga Delisea pulchra, are known to interfere with biofilm ...

Biofilm formation by Salmonella enterica serovar Typhimurium colonizing solid tumours.

Systemic administration of Salmonella enterica serovar Typhimurium to tumour bearing mice results in preferential colonization of the tumours and retardation of tumour growth. Although the bacteria are able to invade the tumour cells in vitro, in tumours they were never detected intracellularly. Ultrastructural analysis of Salmonella-colonized tumours revealed that the bacteria had formed biofi...

Ciprofloxacin-Resistant Salmonella enterica Serotype Typhimurium, China

We characterized 44 Salmonella enterica serotype Typhimurium isolates from Tongji Hospital outpatients in Wuhan, China, May 2002-October 2005. All 31 ciprofloxacin-resistant isolates were also resistant to > or = 8 other antimicrobial drugs and carried > or = 2 mutations in GyrA and 1 mutation in ParC. Class 1 integrons were identified in 37 isolates.
