A Mexican researcher has created an antibiotic from frog skin that heals inflammation of the udders of cows without leaving toxic traces in the milk, in addition to being an alternative to fight bacteria and cure some diseases in humans. 19659002] Alfonso Islas, an academic on the Campus of Biological Sciences of the University of Guadalajara (western Mexico), created and patented this substance called "ranimycin", which uses the antimicrobial properties that the frog naturally develops for himself. protect from the environment.
The Immunology Specialist explained to Efe that he has developed a study funded by the Mexican National Council of Science and Technology to take advantage of the skin of the American Frog (also known as the Frog or Catebe) , raised in the area of Valles de Jalisco to cook a saucer with his hips.
Islands took pieces of frog skin thrown into restaurants to subject it to a process of homogenization and extract the molecules by centrifugation. He discovered that he has 23 peptides or molecules that serve as natural antibiotics.
With them, he created a formula that eliminates bacteria such as Staphylococcus aureus methicillin and Pseudomonas aeruginosa, which cause nosocomial infections and demonstrated resistance to antibiotics such as "We submitted the formula to bacteriological examinations and it was possible to kill bacteria such as Escherichia coli (cause of intestinal diseases), among others.It is broad spectrum and is a very good extract to fight infections, "said the specialist.
One of his colleagues challenged him to try the compound in cows because about 20% of cattle suffer from mastitis. inflammation and infection in the mammary glands caused by machines that extract milk, which occurs during the rainy season.
The antibiotic applied to 280 cows sick managed to heal them in five days and prevented them from being removed from the production process. occurs when they receive treatment with penicillin, because the natural antibiotic leaves no toxic residue in the milk.
"When you put brand name penicillin, you have to remove the cow, you can not give milk, and the human being who drinks milk becomes contaminated.With our natural antibiotic, nothing happens , that is, it is a peptide that is not toxic, which causes no problem, "he said. "Producers lose up to 20% less than selling milk and also have to spend penicillin, and with our product, which we tested in three dairy herds (farms), it's not necessary because the cow is still producing. "
The Mexican and international patents obtained by the islands allow the marketing of this antibiotic, whose dosage has a cost of 2.19 pesos (0. 11 dollars) against the 30 or 40 pesos (1.56 or 2, 08 dollars) that must be paid for brand penicillin.In addition, a 40 gram frog skin can give up to one hundred doses
The researcher has had contacts with entrepreneurs from Mexico and Mexico. Other countries interested in acquiring rights to market the antibiotic.
At the same time, he conducts studies for the application of the antibiotic in humans.
"We have results in the application to cure acne, ringworm on the skin (caused by fungi), athlete's foot and ophthalmic keratitis that presents itself as a complication of a surgery. "However, to market it as a medicine for human use, it is necessary to carry out a medium-term research protocol and obtain the patent," he added.
