title: Study of the mutual effects of sulphadiazine and ciprofloxacin on their uptakes by Pseudomonas aeruginosa.
abstract: A high-performance liquid chromatography (HPLC) assay was developed for ciprofloxacin and sulphadiazine in Isosensitest broth. Combining the HPLC assay with cell dry-weight determinations indicated that both compounds were able to enhance the uptake of the other by log phase Pseudomonas aeruginosa cultured in the presence of the compounds. It is hypothesized that the increased bacterial uptakes are the reason for the enhanced antibacterial activity previously reported for combinations of ciprofloxacin and sulphadiazine.
