Antibiotic efficacies were evaluated by Diff-Quik (Dade, Düdingen, Federal Republic of Germany) staining of Ehrlichia sennetsu in P388D1 murine macrophages grown in 96-well microtiter plates. Sennetsu disease is generally cured with tetracyclines. In vivo, E. sennetsu is susceptible to doxycycline and is resistant to erythromycin, penicillin, and chloramphenicol. Our study confirmed, in vitro, the efficacy of doxycycline, which had an MIC of 0.125 micrograms/ml. E. sennetsu was found to be resistant to erythromycin, chloramphenicol, penicillin, gentamicin, and co-trimoxazole, while it was very susceptible to ciprofloxacin (MIC, 0.125 micrograms/ml) and rifampin (MIC, 0.5 micrograms/ml).
通过对在96孔微量滴定板中培养的P388D1小鼠巨噬细胞中的嗜吞噬细胞无形体进行Diff - Quik(德国联邦共和国杜丁根达德公司)染色,评估抗生素的疗效。腺热一般用四环素治愈。在体内,嗜吞噬细胞无形体对强力霉素敏感,对红霉素、青霉素和氯霉素耐药。我们的研究在体外证实了强力霉素的疗效,其最低抑菌浓度为0.125微克/毫升。发现嗜吞噬细胞无形体对红霉素、氯霉素、青霉素、庆大霉素和复方新诺明耐药,而对环丙沙星(最低抑菌浓度为0.125微克/毫升)和利福平(最低抑菌浓度为0.5微克/毫升)非常敏感。
