Hd. Isenberg et al., RESPONSE OF ENTERIC GRAM-NEGATIVE BACTERIA TO DISKS CONTAINING 20 MICROGRAMS EACH OF AMPICILLIN AND SULBACTAM, Journal of clinical microbiology, 35(2), 1997, pp. 523-524
Ampicillin-sulbactam disks containing either 10 mu g of each drug or 2
0 mu g of each drug were tested against 138 recently, sequentially iso
lated members of the family Enterobacteriaceae. Results obtained with
the higher-content disks corresponded more closely to the impressions
of clinicians.
