Applications of natamycin in killing of ichthyophthirius multifiliis and cryptocaryon irritans

Abstract

The invention belongs to the technical field of chemical product uses, and discloses a prevention and control agent for killing ichthyophthirius multifiliis and cryptocaryon irritans outside aquatic animal bodies, wherein the prevention and control agent comprises, by weight, 5-25% of natamycin, 5-10% of a surfactant, 10-20% of a dissolution agent, and the balance of a solvent. According to the present invention, the natamycin is used, such that advantages of low toxicity, no toxicity on aquatic animals, and less residue are provided; the specific dissolution agent and the specific solvent are utilized, such that the dissolving effect is good, and the dissolution agent can help the entering of the prevention and control agent into the body so as to provide the significant ichthyophthirius multifiliis killing effect; and the prevention and control agent has characteristics of simple preparation, easy use, and low production cost.

Description

[0001] Application of natamycin in killing melon worm and stimulating Cryptocaryonia. technical field [0002] The invention belongs to the technical field of application of chemical products, and specifically relates to the application of natamycin in killing melon worms and stimulating Cryptocaryonia. technical background [0003] Natamycin (Natamycin) is a natural antifungal compound produced by Streptomyces fermentation. It belongs to polyene macrolides. The production of can be widely used in food preservation and antifungal treatment. Its structural formula is: [0004] [0005] Natamycin, the molecular formula is C 33 h 47 NO 13 , Light yellow or light brown powder, melting point is 280°C, slightly soluble in water, hardly soluble in most organic solvents. It relies on its lactone ring structure to interact with sterol compounds on the fungal cell membrane to form antibiotic-sterol compounds, thereby destroying the structure of the fungal cytoplasmic membrane....

Problems solved by technology

The most effective drugs to treat these two parasites are mercurous nitrate and malachite green, and these two drugs have carcinogenic effects, so they have been banned

With the prohibition of these two drugs, formaldehyde, copper sulfate, potassium permanganate, bronopol, etc. are mainly used for the prevention and treatment of these two parasites at home and abroad at present, but these drugs have no effect on the small melon worm and Cryptocaryon irritant. Significant curative effect, while long-term use has brought problems such as drug residues, environmental pollution, drug resistance, etc., so there is an urgent need for drugs with specific effects on these two parasites
