This study compared the in vitro activities of the new long-half-life carbapenem ertapenem (also known as MK-0826 and L-749,345) with those of imipenem, amoxicillin-clavulanate, and ciprofloxacin against 5,558 recent clinical isolates from 11 North American medical centers. We confirmed the greater activity of ertapenem than of imipenem against the Enterobacteriaceae and the greater activity of...

We pursue the definition of a KZ-doctrine in terms of a fully faithful adjoint string Dd ⊣ m ⊣ dD. We give the definition in any Gray-category. The concept of algebra is given as an adjunction with invertible counit. We show that these doctrines are instances of more general pseudomonads. The algebras for a pseudomonad are defined in more familiar terms and shown to be the same as the ones defi...

Fluorescent pseudomonads may be identified through examination of the fluorescence "profiles" of diffusible pigments released into the growth medium. The profiles are obtained in the form of an emission-excitation matrix, the elements of which correspond to fluorescence intensity as a function of multiple exciting and emitting wavelengths. Use of a rapid scanning fluorometer to acquire these da...

The effect of pasteurization on survival in milk of four strains of psychrophilic pseudomonads and of one strain of Alcaligenes was determined. Cell numbers were very low immediately after pasteurization, but increased after storage. The survival of psychrophilic bacteria in pasteurized milk appeared to depend on the initial number of organisms, and detection depended partly on the length of ti...
