Tiamulin Powder

1. Core mechanism of action: precise targeting of the 50S subunit of ribosomes through "molecular sniping"
To understand why it stands out among numerous antibiotics, one must first delve into the microscopic world of its mechanism of action.
1.1 Antibacterial oriented, high concentration sterilization
It belongs to antibacterial antibiotics, but also has bactericidal effects on sensitive bacteria at very high concentrations. Its antibacterial mechanism is to bind to the 50S subunit of bacterial ribosomes and inhibit bacterial protein synthesis.

1.2 Pocket locking of the three ring core
Through in-depth research on its mechanism of action, it was found that its tricyclic core is precisely located at the peptidyl transferase center of the 50S subunit of the ribosome, forming a tight pocket at the A site; At the same time, the protruding part of its tricyclic core covers the P site for tRNA binding, thereby directly inhibiting the formation of peptide bonds. This unique binding mechanism effectively blocks the synthesis of target proteins.

1.3 Differences and Similarities with Macrolides
The mechanism of action is similar to that of macrolide antibiotics, belonging to the same class of Truncarinin antibiotics. However, its effect on Mycoplasma is stronger than that of macrolides, and its unique structure makes it extremely resistant during application. This is the fundamental reason why it is unanimously recommended by industry experts as one of the most effective drugs for controlling porcine respiratory syndrome and porcine ileitis.

2. Clinical core use: Comprehensive coverage of the five major battlefields
1.1 Chronic respiratory disease (CRD) in chickens - the "ace battlefield" of tetracycline
Chronic respiratory disease in chickens is a stubborn respiratory disease caused by Mycoplasma gallisepticum and Mycoplasma gallisepticum, which causes huge economic losses in the global poultry industry. It has significant inhibitory effects on Mycoplasma gallisepticum, Mycoplasma gallisepticum, and Mycoplasma synovium, and is one of the preferred drugs for treating this disease.

In addition, it is also effective against Staphylococcus aureus synovitis in chickens and can be used alone or in combination with other drugs.

2.2 Mycoplasma hyopneumoniae pneumonia (asthma) - the "battle for fame" of tetracycline
Mycoplasma hyopneumoniae pneumonia, commonly known as "asthma", is the most widespread and difficult to purify important disease in pig farms. Mild cases have low feed conversion rates and slow growth, while severe cases can lead tosecondary infections such as blue ear disease virus and circovirus, causing serious losses.

Taimiao fungicide has strong antibacterial activity against Mycoplasma hyopneumoniae (MIC only 0.015 μ g/mL), which can quickly relieve symptoms such as cough and dyspnea, reduce the degree of lung damage, and improve the production performance of livestock and poultry. Because its effect on mycoplasma is stronger than that of macrolides and it has almost no resistance, tetracycline is often used as the preferred drug for controlling mycoplasma in pig farms.

2.3 Porcine contagious pleuropneumonia - the "golden partner" with doxycycline
Porcine infectious pleuropneumonia caused by Actinobacillus pleuropneumoniae is another major respiratory killer.

It has a certain effect on this pathogen, and in clinical practice, the plan of "80% tetracycline 150g/ton feed+10% doxycycline 1000g/ton feed+20% florfenicol 400g/ton feed" is often used. After weaning and transitioning to group and conservation and fattening, it is used continuously for 10 days, and the effect is significant.

2.4 Porcine Treponema dysentery (blood dysentery) - a dominant field in the world
Porcine dysentery caused by Treponema pallidum is another major intestinal disease in pig farms. Tiamulin powder mushroom extract has good antibacterial activity against porcine dysentery spirochetes and colonic trichomonas,byinhibitingpathogen proliferation, reducing intestinal mucosal inflammation, and restoring normal intestinal function.

For pig ileitis, the commonly used clinical protocol is "80% tetracycline 150g/ton feed+20% doxycycline 2000g/ton feed", continuously used for 10 days.

2.5 Porcine bacterial enteritis and mixed infections - the "expansion weapon" of streptomycin combination
Mixing with streptomycin at a ratio of 1:4 can treat bacterial enteritis, bacterial pneumonia, and swine dysentery caused by spirochetes in pigs. It has significant therapeutic effects on pneumonia caused by mixed infections of Mycoplasma pneumoniae, Bordetella bronchiseptica, and Pasteurella multocida.

A 1:3 ratio with streptomycin can increase the efficacy of drugs by 3-8 times in clinical practice, making it a model for combination therapy.

3. Growth promoting effect: the 'invisible dividend' under sub therapeutic doses
Not only is it a powerful tool for treating diseases, but it is also an expert in promoting growth. At sub therapeutic doses (low doses), multiple growth promoting effects can be exerted:
Regulating the balance of gut microbiota: inhibiting the proliferation of harmful bacteria and maintaining the stability of gut microbiota;

Improve feed conversion rate: reduce nutrient waste caused by intestinal diseases;
Promote animal growth and development: shorten the growth cycle and reduce breeding costs.
This characteristic makes it widely used as a feed drug additive for pigs, with a bioavailability of about 85% after single dose administration. The peak blood drug concentration is reached within 2-4 hours, and the blood drug concentration is maintained for 24 hours, with the highest concentration in lung tissue and extremely high drug utilization efficiency.

4. Frontier Exploration: Emerging Applications Beyond Veterinary Medicine
4.1 Inhibition of breast cancer -- a new hope of CD73 target
The study by Ronald N. Jones et al. showed that tetracycline can inhibit the activity of CD73 in vitro enzyme activity assays, with the highest inhibitory activity. The researchers speculate that tamarin may inhibit breast cancer by inhibiting CD73, and relevant validation tests are in progress.

If this discovery is clinically confirmed, it will cross over from livestock and poultry antibiotics to become a candidate molecule for anti-tumor drugs.
4.2 Other potential applications
δ - tocopherol is still being used as a control drug in in in vivo studies for the prevention of prostate cancer, and its broad biological activity is gradually being revealed.
