There is cross-resistance between different varieties of tetracycline antibiotics.
3.The mechanism of action of the drug for the drug can specifically with the bacterial ribosome 30S subunit A site binding, inhibition of peptide chain growth and the impact of bacterial protein synthesis.
4.For dysentery, trachoma, conjunctivitis, pneum
