their antibacterial activities clearly corresponded to their resistance to the hydrolytic action of the beta-lactamase : namely , the correlation coefficients in regression curves of cefotaxime , ceftizoxime , and cefmenoxime , which were expressed by the antibacterial activity ( x axis ) and the beta-lactamase activity ( y axis ) were 0.098 , 0.034 , and 0.163 , respectively .
