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