An examination of 99 field and reference strains of Citrobacter freundii showed 79% of them to be resistant to cephaloridine and sensitive to carbenicillin, while 96% of 45 field and reference strains of Citrobacter koseri examined were sensitive to cephaloridine and resistant to carbenicillin. Susceptibility tests with these two antibiotics are therefore useful in separating the two species of Citrobacter.
对99株弗氏柠檬酸杆菌的野外菌株和参考菌株进行检测发现,其中79%对头孢菌素耐药,对羧苄青霉素敏感;而对45株科氏柠檬酸杆菌的野外菌株和参考菌株检测发现,96%对头孢菌素敏感,对羧苄青霉素耐药。因此,用这两种抗生素进行药敏试验有助于区分这两种柠檬酸杆菌。
