Comparative in vitro evaluation of the antimicrobial activity of flurithromycin by means of the MS-2 Abbott Research System.

The study reports the results of an in vitro comparative evaluation of flurithromycin by means of MS-2 research system analyzing the growth curve patterns of recently isolated strains of S. aureus, S. epidermidis, S. faecalis and H. influenzae. Flurithromycin is provided with superior activity to that of josamycin and practically superimposed on that of erythromycin. Of the 4 bacterial species studied, S. faecalis is the most sensitive, followed by Staphylococci and H. influenzae in decreasing order of sensitivity.
