title: In vitro activity of A-56268 (TE-031), a new macrolide, compared with that of erythromycin and clindamycin against selected gram-positive and gram-negative organisms.
abstract: The in vitro activity of A-56268 was determined and compared with that of erythromycin and clindamycin against a limited spectrum of 401 gram-positive and gram-negative organisms. A-56268 was quite active against erythromycin-susceptible Staphylococcus aureus, Neisseria gonorrhoeae, Listeria monocytogenes, Streptococcus pneumoniae, Streptococcus pyogenes, and group B streptococci and was moderately active against Campylobacter fetus subsp. fetus. A-56268 was consistently bactericidal only for S. pneumoniae. The activity of A-56268 was comparable to that of erythromycin against most organisms tested.
