How antibiotics work:
 
Sulfonamides:
This class of drug block nucleic acid metabolism in cells, and they have a very high alkalinity. THIS CLASS OF DRUG SHOULD NEVER BE GIVEN WHEN KIDNEY DISEASE IS SUSPECTED (i.e.) Dropsy.  It can be fatal. Also this class of drug is best used when fed, NOT when added to water.
 
Penicillins:
This class works to weaken the bacterial cell wall so that when the cell divides (reproduces), it does not form properly and bursts as it grows, thereby killing the cell. For this drug to work, the bacteria cells must be actively growing and reproducing.
 
Gentamycin, Kanamycin, Neomycin:
These three effect the bacterial cell membrane which is responsible for bringing nutrients into the cell and taking waste out of the cell. The antibiotics disrupt this process. THESE ANTIBIOTICS CAN BE TOXIC IF OVERDOSED.
 
Erythromycin, Neomycin, Kanamycin, Tetracylines, Chloramphenicol:
These antibiotics prevent protein synthesis and effect the cells ability to reproduce.
