Ampicillin and urticaria.

Bioavailability of ampicillin (anhydrous) and ampicillin trihydrate.

Ampicillin susceptibility and ampicillin-induced killing rate of Escherichia coli.

The killing rate induced by ampicillin was determined in 20 strains of Escherichia coli. The apparent generation rate constant for each E. coli showed a characteristic concentration-dependent course. This course can be mathematically described and is determined by four parameters. Three of these parameters determine the speed of the process, and the fourth parameter determines a minimal concent...

[Urticaria].

ma are cutaneous manifestations of localized edema. They are common skin diseases that typically result from the same pathophysiologic processes. The primary difference between the disorders is that urticaria is associated with localized edema involving the upper dermis, whereas angioedema is associated with localized edema involving deeper layers of the skin, as well as subcutaneous and submuc...

Urticaria

Effects of ampicillin-amikacin and ampicillin-rifampin on enterococci.

Fifty-seven clinical isolates of enterococcus were tested for susceptibility to 10 antibiotics in a microtiter broth dilution system. Amoxicillin, ampicillin, vancomycin, and rifampin inhibited all strains at concentrations easily achievable in blood. Resistance to rifampin developed rapidly. Of the aminoglycosides, gentamicin was most active, followed in decreasing order by tobramycin, amikaci...
