Postantibiotic effects of imipenem and enoxacin against S. typhimurium and S. enteritidis and the influence on their surface hydrophobicity

摘要: The influence of the postantibiotic effect (PAE) and sub-MICs (PA SME) imipenem enoxacin on surface hydrophobicity ofS. typhimurium andS. enteritidis strains were studied by evaluating Congo red binding aggregation in molar solutions ammonium sulfate (SAT). A PAE was induced 2× 4× MIC antibiotics tested for 0.5 h. Suprainhibitory concentrations againstS. a short (0.3–0.6 h) compared toS. (6.0–9.7 h). Suprasubinhibitory did not allow regrowth enteritidis. Similar results also found enoxacin. Evaluation hydrophobic properties salmonellas after affecting both PAEs PA SMEs has shown that at 4×MIC 4×MIC+0.3×MIC partially influenced typhimurium. S. more susceptible toward tested.
