Ulwahlulo: Amachiza okulwa neebhaktheriya ahlulwe abe ngamacandelo amabini: i-antibiotics kunye neyeza zokwenziwa kwe-antibacterial. Into ebizwa ngokuba yi-antibiotics yi-metabolites eveliswa yi-microorganisms,  enokuthintela ukukhula okanye ukubulala ezinye iintsholongwane ezithile.  Izinto ezibizwa ngokuba yi-synthetic antibacterial drugs zizinto ezilwa ne-antibacterial eziveliswa ngabantu ngokusebenzisa i-chemical synthesis, engaveliswa yi-microbial metabolism.

Amayeza okubulala iintsholongwane: Amayeza okubulala iintsholongwane ngokuqhelekileyo ahlulahlulwe abe ziindidi ezisibhozo: 1. Iipenicillins: penicillin, ampicillin, amoxicillin, njl.; 2. Cephalosporins (pioneermycins): cephalexin, cefadroxil, ceftiofur, cephalosporins, njl.; 3. Aminoglycosides: streptomycin, gentamicin, amikacin, neomycin, apramycin, njl.; 4. Macrolides: erythromycin, roxithromycin, tylosin, njl.; 5. Tetracyclines: oxytetracycline, doxycycline, aureomycin, tetracycline, njl.; 6. I-Chloramphenicol: i-florfenicol, i-thiamphenicol, njl.; 7. I-Lincomycins: i-lincomycin, i-clindamycin, njl.; 8. Ezinye iindidi: i-colistin sulfate, njl.
