Antimicrobial solutions that work.
Microtide is a new antimicrobial peptide that has been designed to combat gram-negative bacteria such as E. coli and Salmonella.
It contains microcin ST19R22, an antimicrobial agent that has been optimized for efficacy and safety. Its unique mechanism allows it to kill gram-negative bacteria effectively with low potential for resistance.
Microtide has a highly favorable safety profile, with no toxicity and minimal risk of adverse effects. It represents a significant advancement in the fight against gram-negative bacterial infections and is an important new treatment option for livestock.

Field trial results
The field trial conducted on Microtide was carried out in Myanmar by the University of Veterinary Science, Yezin between September–October 2020. The trial involved 6 closed houses, with 2 houses allocated per group and 10,000 chickens per house. The three groups were: treated with Microtide, treated with neomycin sulphate, and untreated. Promising results were observed in the Microtide-treated group, which showed a reduction of 60% in mortality rates compared to the untreated group and similar results when compared to the group treated with neomycin.
These results demonstrate Microtide’s potential as a beneficial solution for the poultry industry in terms of enhanced health and productivity. Its antimicrobial properties offer a novel approach to combat bacterial infections and improve overall chicken well-being in the poultry sector.
The successful trial in Myanmar, conducted in a large-scale setting with 6 closed houses and three distinct groups, underscores the potential of Microtide as a practical and effective solution for real-world poultry farming.
