Naik H, Duncan C
J Food Prot . 2019 Feb; 41(2):100-103. PMID: 30795180
Thermal inactivation studies of Clostridium perfringens enterotoxin revealed that biological activity was destroyed within 5 min at 60 C, whereas about 10% or less residual serological activity could be detected...

J Chemother . 2007 Sep; 19(4):392-7. PMID: 17855183
Fluoroquinolone-resistance among pneumococci is low; however the number of isolates with a single ParC mutation has increased. Consequently, more potent agents are needed to minimize resistance selection. We investigated the...

Bast D, Dresser L, Duncan C, Walker S, Mandell L, Low D, et al.
J Chemother . 2007 Feb; 18(6):634-40. PMID: 17267342
Standard 7-14 day (d) courses of antimicrobial therapy for community-acquired pneumonia (CAP) are thought to have contributed to the emergence of resistant pneumoccoci. Consequently, short-course fluoroquinolone regimens have been proposed...

Low D, Muller M, Duncan C, Willey B, de Azavedo J, McGeer A, et al.
Antimicrob Agents Chemother . 2002 Mar; 46(4):1119-21. PMID: 11897603
The in vitro activity of BMS-284756 against 602 Staphylococcus aureus isolates, including 152 that were both methicillin and ciprofloxacin resistant (MIC > or = 4 microg/ml), was determined. For ciprofloxacin-susceptible...

Bast D, Low D, Duncan C, Kilburn L, Mandell L, Davidson R, et al.
Antimicrob Agents Chemother . 2000 Oct; 44(11):3049-54. PMID: 11036021
We report on amino acid substitutions in the quinolone resistance-determining region of type II topisomerases and the prevalence of reserpine-inhibited efflux for 70 clinical isolates of S. pneumoniae for which...
