[HR 810 (cefpirome). Experimental evaluation of the in vitro and in vivo antibiotic activity of a new amino-2-thiazole methoxy- imino cephalosporin].

HR 810 or cefpirome is a new amino thiazole cephalosporin whose specific characteristic is a cyclopentenopyridinium group in position 3 of the cephem nucleus. This structure is responsible for a broad spectrum of activity, covering Enterobacteriaceae, including cephalosporinase-producing Enterobacter spp. and Citrobacter spp., Staphylococcus aureus, Pseudomonas aeruginosa and group D Streptococci.
