摩尔计算器

Citreamicin alpha（LL-E 19085-alpha）是一种抗生素，其对429例临床分离的革兰氏阳性球菌的体外抗菌活性已通过琼脂稀释法进行测试。这些微生物包括313株葡萄球菌和116株链球菌。Citreamicin alpha的体外活性与氨苄西林、阿莫西林、头孢噻吩、红霉素和万古霉素进行了比较。对于葡萄球菌，Citreamicin alpha的MIC值范围在0.12-4.0 μg/ml，对于链球菌属的Streptococcus pyogenes为0.03-0.12 μg/ml。然而，肠球菌相对较耐药，需要2.0 μg/ml的试剂来抑制64%的62个测试菌株。这种抗生素的体外活性远优于氨苄西林、阿莫西林、头孢噻吩和红霉素，但与万古霉素相当或略差。

生物活性

Citreamicin alpha (LL-E 19085-alpha) is an antibiotic whose in vitro antimicrobial activity against 429 clinical isolates of Gram-positive cocci has been tested by the agar dilution method. These microorganisms included 313 strains of Staphylococci and 116 strains of Streptococci. The in vitro activity of Citreamicin alpha was compared with that of ampicillin, amoxicillin, ceftriaxone, erythromycin, and vancomycin. For Staphylococci, the MIC values of Citreamicin alpha ranged from 0.12-4.0 μg/ml, and for Streptococcus pyogenes of the genus Streptococcus, it was 0.03-0.12 μg/ml. However, enterococci were relatively resistant, requiring 2.0 μg/ml of the agent to inhibit 64% of the 62 tested strains. The in vitro activity of this antibiotic was much better than that of ampicillin, amoxicillin, ceftriaxone, and erythromycin, but comparable or slightly inferior to that of vancomycin.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
