AIM: The aim of this preliminary study was to investigate the in vitro effect of "non-antibiotic" trimebutine against reference strains Staphylococcus aureus ATCC 29213, ATCC 25923, Escherichia coli ATCC 25922, ATCC 35218, Pseudomonas aeruginosa ATCC 27853 and Enterococcus faecalis ATCC 29212; microbiota that are potentially involved in the pathophysiology of post-infectious functional gastrointestinal disorders.
METHODS: Trimebutine activity was assessed by the broth microdilution method according to Clinical and Laboratory Standards Institute recommendations against reference strains S. aureus ATCC 29213 and ATCC 25923, E. coli ATCC 25922 and ATCC 35218, P. aeruginosa ATCC 27853 and E. faecalis ATCC 29212. Bactericidal activity of the compound was determined by spreading a 10 μL aliquot on Mueller-Hinton agar from each dilution showing non-visible growth. All tests were carried out in triplicate.
RESULTS: Trimebutine was active against all strains tested presenting with MIC ranging from 1024 to 4000 mg/L. MIC and MBC were similar for E. coli ATCC 25922 and P. aeruginosa ATCC 27853 whereas for Gram-positive isolates and E. coli ATCC 35218 the MBC was higher.
CONCLUSIONS: We demonstrated the in vitro bacteriostatic/bactericidal activity of trimebutine against bacteria frequently colonizing the gastrointestinal tract and potentially involved in human gastrointestinal infections that might trigger post-infectious functional gastrointestinal disorders.
