Partial macrolide and streptogramin B

PMS, partial macrolide and streptogramin B antibiotics MS, macrolide and streptogramin B antibiotics M, macrolide antibiotics. 

In recent years, new resistance phenotypes (macrolide and streptogramin B antibiotics [MS] or partial macrolide and streptogramin B antibiotics [PMS], and macrolide antibiotics [M]) have been observed in elinical isolates of staphylococci and streptococci. Ross et al. [61, 125, 193] and Goldman and Capobianco [126] reported that MS-resistant strains of Staphylococcus epidermidis were resistant to 14- or 15-membered-ring macrolides and streptogramin B, but were susceptible to 16-membered-ring macrolide and lincosamide antibiotics.
