Our Lead Product: Y-Complex – The Anti-Mastitis Treatment

 

Our first product is a biological pharmaceutical for the treatment of dairy cattle infected with bovine Mastitis. Mastitis is considered the most expensive disease to the dairy industry, costing fluid milk producers worldwide up to $7 billion in lost revenues and expenses each year. It not only affects the health of the cows, but the quality of milk expressed from them. Mastitis is most prevalent in the intensive dairy operations that characterize modern dairy farming. It is also believed that higher yielding cows are more susceptible to the disease. 

 

To date, while a number of “vaccines" and antibiotics are available on the market, there is no wonder drug for either the prevention or treatment of the disease. Vaccines have been developed for two specific pathogens (E. coli and Staph Aureus), but have not been found effective in reducing the incidence of the disease. Their contribution to Mastitis treatment appears to be in mitigating the severity of the infection once it has been contracted.

 

Antibiotics, still the most popular method of post-infection treatment, are highly problematic. According to Pharmacia Animal Health in their promotional literature for Pirsue®, a relatively new antibiotic product, traditional antibiotics are only 20-30% effective in curing the disease. They leave residues in milk and consequently, milk from cows receiving antibiotic treatment is “withdrawn" from the market several days subsequent to use. Moreover, pathogens can build resistance to antibiotics and their efficacy may decrease over time. While antibiotics have been developed to address certain Mastitis pathogens, our Y Complex has a broad spectrum antimicrobial activity against most of the mastitis pathogens.

 

Y-Complex’s Competitive Advantages

 

Yamit’s Y-Complex is a biological pharmaceutical that can be as effective, if not more effective, than antibiotics in treating Mastitis. The unique technology behind Y-Complex assures that the target pathogens will be neutralized through their binding to the carrier. By combining the use of the antibody, Yamit's technology can treat a large variety of pathogens, including viruses.

Since it is a biological rather than chemical substance, it does not suffer from the major drawbacks discussed above. There are no drug residues left in the milk, as both the Complex and the pathogen are washed away with the first milking. In pre-clinical trials Y-Complex was successfully tested for both toxicity and residue. Twenty four hours post administration, no residue was found in milk, and only minor local cellular response was observed on the treated quarter.

Y-Complex could well be the first effective post-infection treatment for “environmental Mastitis”. Yamit has developed and tested the Y-Complex in pre-clinical trials for toxicity and efficacy. Two of the most common pathogens causing this disease, coliform (E-coli) and Streptococcus dysgalactiae, were examined on a small sample of cows. Results of these tests indicate tat Y-Complex is effective in treating both pathogens, eradicating E-coli within two days of treatment. Earmarked as the Company’s first product Y-Complex for E-Coli targets what is held to be the most frequent cause of clinical Mastitis, accounting for 40-60% of all cases. There are currently no FDA-approved drugs on the market today dedicated to curing Mastitis caused by E-coli.
