Abstract
Paldimycin (U-70138F) is a new antimicrobial agent with activity against gram-positive cocci. Clinical isolates of staphylococci and streptococci were tested. MICs were higher in Mueller-Hinton broth than in nutrient broth. Change in pH had minimal effect on the MICs in either broth. When inoculum size was varied, an inoculum effect was observed. The gram-positive cocci tested were generally more susceptible to paldimycin than to vancomycin.
