[Experimental study of the antibiotic activity of cefuroxime]

The antimicrobial spectrum of cefuroxime, an antibiotic of the cephalosporin family was studied in vitro with respect to 11 species (16 strains) of gram-positive and gram-negative bacteria and in vivo on albino mice with experimental salmonellosis or pneumococcal infections. The bacteria were either test cultures or isolates from patients. The studies showed that cefuroxime had a wide antibacterial spectrum in vitro. It inhibited the growth of Staph. aureus, Str. pneumoniae, E. coli, Salm. typhimurium, Kl. pneumoniae, Bac. subtilis and had no effect on Ps. aeruginosa, Pr. vulgaris, M. tuberculosis and M. fortuitum. Cefuroxime had also a high bacteriostatic effect with respect to the experimental pneumococcal infection and a lower bacteriostatic effect with respect to the experimental salmonellosis infection.
