5 y.o. girl has green smelly vaginal mucus, persists for over 7 months, 10d of cefixime and 10d of keflex did not cure. per tests no object in vag, no sexual abuse. not fungal per culture. normal??

No, not normal. Colored discharge with odor means infection. Vaginal infections often require different antibiotics than these, e.g. metronidazole or clindamycin. (Cefixime and cephalexin [Keflex] are almost identical; that was really no change at all.) Double check about sexual abuse and STDs, including STD testing (gonorrhea, chlamydia, trichomonas). She needs pediatric ID specialist. Good luck.
