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