Lincomycin hydrochloride is the product of the growth of Streptomyces lincolnensis (Streptomyces lincolnensis) flora. It is a kind of Lincosamides (Lincosamides) basic antibiotic. It acts on the 50S subunit of the ribosome of sensitive bacteria. Prevents the extension of the peptide chain, thereby inhibiting the protein synthesis of bacterial cells, with antibacterial effect, but also has a bactericidal effect on highly sensitive bacteria at high concentrations. The antibacterial spectrum is the same as lincomycin, but the antibacterial activity is stronger
Lincomycin hydrochloride has a strong antibacterial effect on Gram-positive bacteria, some anaerobic bacteria and mycoplasma, and its antibacterial spectrum is narrower than that of erythromycin. Staphylococcus aureus, hemolytic streptococcus, pneumococcus and Mycoplasma hyopneumoniae, Mycoplasma gallisepticum are sensitive to this product, but enterococci are generally resistant to this product; anaerobic bacteria such as Bacteroides, Tetanus, Clostridium, Clostridium weischii, Peptococcus, etc. are also sensitive to this product. It is mainly used to treat various infections caused by gram-positive bacteria, especially penicillin-resistant gram-positive bacteria, chronic respiratory diseases of poultry caused by mycoplasma, swine asthma, anaerobic infections such as necrotizing enteritis in chickens, etc. It is used to treat swine treponema dysentery, toxoplasmosis and actinomycosis in dogs and cats.
