The combination of tylosin and doxycycline has additive action. Doxycycline belongs to the group of tetracyclines and has bacteriostatic action against many Gram-positive and Gram-negative bacteria like Bordetella spp., Campylobacter spp., E. coli, Haemophilus spp., Pasteurella spp., Salmonella spp., Staphylococcus spp. and Streptococcus spp. Doxycycline is also active against Chlamydia spp., Mycoplasma spp. and Rickettsia spp. The action of doxycycline is based on inhibition of bacterial protein synthesis. Doxycycline has a great affinity to the lungs and is therefore especially useful for treatment of bacterial respiratory infections. Tylosin is a macrolide antibiotic with a bacteriostatic action against Gram-positive and Gram-negative bacteria like Campylobacter spp., Pasteurella spp., Staphylococcus spp., Streptococcus spp., Brachyspira spp. and Mycoplasma spp.
