Missense mutation in the PAS2 domain of phytochrome A impairs subnuclear localization and a subset of responses.

Phytochrome A signaling shows two photobiologically discrete outputs: so-called very-low-fluence responses (VLFR) and high-irradiance responses (HIR). By modifying previous screening protocols, we isolated two Arabidopsis mutants retaining VLFR and lacking HIR. Phytochrome A negatively or positively regulates phytochrome B signaling, depending on light conditions.

In vitro activity of gatifloxacin compared with gemifloxacin, moxifloxacin, trovafloxacin, ciprofloxacin and ofloxacin against uropathogens cultured from patients with complicated urinary tract infections.

Minimum inhibitory concentrations (MICs) of gatifloxacin were compared with those of gemifloxacin, moxifloxacin, trovafloxacin, ciprofloxacin and ofloxacin using an agar dilution method for 400 uropathogens cultured from the urine of urological patients with complicated and/or hospital-acquired urinary tract infections (UTI). The collection of strains was made up of Enterobacteriaceae (34.5%), enterococci (31.

In vitro activity of enoxacin versus ciprofloxacin, fleroxacin, lomefloxacin, ofloxacin, pefloxacin, and rufloxacin against uropathogens.

Minimum inhibitory concentrations (MIC) of enoxacin, ciprofloxacin, fleroxacin, lomefloxacin, ofloxacin, pefloxacin and rufloxacin were determined against 400 uropathogens cultured from the urine of patients with complicated and/or hospital-acquired urinary tract infections (UTI) using an agar dilution method. The bacterial spectrum consisted of Entero-bacteriaceae (34.5%), enterococci (31.
