Other organisms isolated from UK during this period also included cefruoxime resistant Enterococcus faecalis, Klebsiella pneumoniae and genus Proteus mirabilis.

Among the different -lactams available, carbapenems were used against ESBL because they are relatively resistant to hydrolysis by most of the lactamases. But, however with the advent of carbapenem resistant strains other a lternatives like mecillinam and fosfomycin may be used to treat UTIs caused by ESBL producing E. coli with much success.One of the most common problems hovering human females is Urinary tract infection.
