Tylosin

Tylosin structure

Tylosin is a macrolide antibiotic that is produced by the bacterium Streptomyces fradiae. It is primarily used in veterinary medicine to treat a variety of bacterial infections in animals, particularly in livestock such as cattle, swine, and poultry. Tylosin is effective against a range of Gram-positive and some Gram-negative bacteria, as well as Mycoplasma species.

Mechanism of Action

Tylosin works by inhibiting protein synthesis in bacteria. It binds to the 50S subunit of the bacterial ribosome, thereby preventing the translocation of peptides during translation. This action is similar to that of other macrolides, such as erythromycin.

Uses in Veterinary Medicine

Tylosin is used to treat various infections in animals, including:

• Bovine respiratory disease
• Swine dysentery
• Mycoplasma pneumonia in poultry
• Mastitis in dairy cattle

It is also used as a growth promoter in some countries, although this practice is controversial and banned in others due to concerns about antibiotic resistance.

Administration and Dosage

Tylosin can be administered in several forms, including:

• Oral powder
• Injectable solution
• Premix for feed

The dosage and administration route depend on the type of animal and the specific condition being treated.

Side Effects and Precautions

Common side effects of tylosin include gastrointestinal disturbances such as diarrhea and colic. Allergic reactions can also occur, although they are rare. It is important to follow veterinary guidance when using tylosin to avoid potential side effects and ensure effective treatment.

Regulatory Status

The use of tylosin is regulated in many countries. In the European Union, its use as a growth promoter is banned. In the United States, it is approved for use in livestock but is subject to veterinary oversight.
