K. Kamigiri et al., YM-32890-A AND YM-32890-B, NEW TYPES OF MACROLIDE ANTIBIOTICS PRODUCED BY CYTOPHAGA SP, Journal of antibiotics, 50(7), 1997, pp. 556-561
Two new types of macrolide antibiotics, YM-32890 A. and B, have been i
solated from the fermentation broth of Cytophaga sp. YL-O2905S. In thi
s paper, the taxonomy of the producing strain, Fermentation, isolation
, structure elucidation, and biological activity of the antibiotics ar
e reported. YM-32890 A inhibits the growth of staphylococci including
a macrolide-resistant strain, but shows no antimicrobial activity agai
nst other Gram-positive, Gram-negative bacteria and yeast.
