The effect of recombinant human interleukin-1 alpha (IL-1) on the resistance of normal and bone marrow-suppressed mice against bacterial infection was evaluated. IL-1 induced neutrophilia and enhanced the resistance of normal mice against acute, systemic intraperitoneal infection with Klebsiella pneumoniae and methicillin-resistant Staphylococcus aureus.(More)
Enterotube, a multiple-test system which combines nine biochemical tests useful in the identification of members of the family Enterobacteriaceae, was tested and compared with the PathoTec test system in the identification of gram-negative bacilli isc ated from clinical specimens. It was found that both the Enterotube and the PathoTec systems rapidly and(More)
1-(2-Nitro-1-imidazolyl)-3-methoxy-2-propanol (RO 7-0582) and 2-methyl-5-nitroimidazole-1-ethanol (Metronidazole), substances known to be potent trichomonacides, were shown to inhibit obligate anaerobic bacteria in vitro but were essentially without effect at the doses tested against bacteria capable of growing aerobically. A similar effect was noted in(More)
Ceftriaxone (Ro 13-9904) was compared with other newer beta-lactam antibiotics for activity in experimental infections of mice with Enterobacteriaceae, Haemophilus influenzae, Pseudomonas aeruginosa, and gram-positive bacteria. Overall, ceftriaxone was equal or superior to cefotaxime and cefoperazone against systemic infections. All three drugs were highly(More)
Recent clinical isolates (approximately 150 strains) of the family Enterobacteriaceae were examined by agar diffusion, microdilution, and the Autobac automated system for their responses to beta-lactam antibiotics singly and in combination with amdinocillin (formerly called mecillinam). The ratio of ampicillin, carbenicillin, and cephalothin to amdinocillin(More)
Both an oral and a parenteral form of a 6beta-amidinopenicillanic acid derivative were found to have appreciable activity against gram-negative bacteria and poor activity against gram-positive bacteria in vivo. When administered orally or parenterally, definite synergy was demonstrated between the amidinopenicillins and ampicillin, amoxicillin,(More)
