Chlortetracycline belongs to the group of tetracyclines and acts bacteriostatic against many Gram-positive and Gram-negative bacteria like Bordetella, Campylobacter, Chlamydia, E. coli, Haemophilus, Mycoplasma, Pasteurella, Rickettsia, Salmonella, Staphylococcus and Streptococcus spp. The action of chlortetracycline is based on inhibition of bacterial protein synthesis. Chlortetracycline is mainly excreted in urine, for a small part in bile and in lactating animals in milk.
