Wh. Traub et al., INTRACELLULAR BACTERICIDAL ACTIVITIES OF CEFPIROME AND MEROPENEM AS COMPARED WITH CIPROFLOXACIN AGAINST SERRATIA-MARCESCENS, Medical microbiology letters, 3(4), 1994, pp. 173-180
The addition of phenylbutazone (2 mg/ml) to 55 % (v/v) of fresh defibr
inated human blood permitted leukocytic ingestion of serum-resistant S
erratia marcescens bacteria, but blocked phagocytic killing activity.
A group A (phage tail) bacteriocin of S. marcescens, bA(+) 16, was use
d to kill extraphagocytic test bacteria. The fluoroquinolone ciproflox
acin rapidly killed ingested bacteria, whereas the cephem cefpirome an
d the carbapenem meropenem displayed kinetically delayed intracellular
bactericidal activity.
