Josamycin (EN-141, Kitasamycin A3, Leucomycin A3, Turimycin A5) is a macrocyclic lipid antibiotic derived from Streptomyces nalopyces that has a wide range of antimicrobial activities against a range of pathogens.
The antibacterial action of lucamycin is similar to erythromycin. It has antibacterial effects on gram-positive bacteria such as Staphylococcus aureus, hemolytic streptococcus, pneumococcus, diphtheria bacillus, tetanus bacillus, anthrax bacillus, etc. It also has effects on some gram-negative bacteria such as gonococcus Chemicalbook, Bacillus pertussis, Brucella, etc. It is effective against mycoplasma, chlamydia, Rickettsiae and spirochaeta, etc. It is also sensitive to Campylobacter and Legionella, and is more effective against gram-positive anaerobic bacteria than erythromycin.
The main biodetection method for the titer of oxamycin was the tube and disc method. By using the diffusion effect of antibiotics in AGAR medium, the standard solution with known concentration and the sample with unknown concentration were expanded on the AGAR surface containing the sensitive experimental bacteria. The inhibitory zone was generated due to the inhibition effect on the tested bacteria, and the inhibitory zone size was proportional to the concentration of antibiotics. This method uses antibiotics to inhibit the characteristics of sensitive bacteria, in line with the actual situation of clinical use, so it is recognized internationally.
