Activities of pefloxacin and ciprofloxacin in experimentally induced Pseudomonas pneumonia in neutropenic guinea pigs

Activities of pefloxacin and ciprofloxacin in experimentally induced Pseudomonas pneumonia in neutropenic guinea pigs.

Pefloxacin and ciprofloxacin are two new quinoline carboxylic acid derivatives that have activity in vitro against a wide range of gram-negative bacteria, including Pseudomonas aeruginosa. Using a well-standardized model of Pseudomonas pneumonia in neutropenic guinea pigs, we tested the efficacy in vivo of these new agents. Both were highly effective in increasing survival and decreasing bacter...

Activities of pefloxacin and ciprofloxacin against experimental malaria in mice.

We investigated the in vivo antimalarial activities of pefloxacin and ciprofloxacin in Swiss albino mice infected intravenously with 5 x 10(6) Plasmodium yoelii N67 parasites 1 h before treatment. Groups of 20 mice received a subcutaneous injection of 40, 80, or 160 mg of ciprofloxacin or pefloxacin per kg of body weight every 8 h for 3 days. Parasitologic activity was assessed on day 4, and su...

Pseudomonas aeruginosa Pneumonia in Neutropenic Mice

The effects of the combination of a murine monoclonal antibody (MAb) specific for the 0 side chain of Pseudomonas aeruginosa Fisher immunotype 1 lipopolysaccharide and sparfloxacin in a neutropenic mouse model of P. aeruginosa pneumonia were examined. Under the condition that neither MAb at a dose of 500 Rg per mouse administered intravenously nor a suboptimal dose of oral sparfloxacin (5 mg/kg...

Experimental Pneumonia in Guinea Pigs

1. Anti-pneumotoxic sera prepared in rabbits or horses by immunization with sterile filtrates of the pneumotoxin, under certain conditions protect against the pneumonia caused by the intratracheal injections of mixtures of living pneumococci and toxic autolysates. 2. The protection against the development of pneumonia is heterologous, at least as regards Type I, Type II, viz.: an anti-autolysat...
