INVESTIGATION OF NEW DISINFECTANT “UNIVAYT” FUNGICIDAL ACTIVITY
Introduction. Spreading of resistant microorganisms and fungi to disinfectants is a serious problem for animal health. The disease of animals is caused by resistant agents, which are not easy to treat and can lead to significant mortality. Only one way to overcome the resistance of agents is to search substances, among the new chemical groups too, that obtains high bactericidal and fungicidal effect. Development medicines on their basis for the prevention of diseases that are caused by bacteria and fungi, is an urgent task today.
The goal of the work was to investigate the fungicidal activity disinfectant “Univayt”.
Materials and methods. To determine the sensitivity of micromycetes strains genera Aspergillus, Penicillium, Fusarium to the disinfectant “Univayt” using serial dilutions of preparations and disk sensitivity method. In the study of fungicidal activity of the preparations we prepared aqueous solutions of “Univayt” in 0.5; 1.0; 2.5; 5.0 and 6.0% concentrations and spore suspension of 7-day fungi cultures of the genera Aspergillus, Penicillium, Fusarium, which included 120 diasporas to 0.2 cm3 (working dilution).
Results of research and discussion. As a result of our investigations was found that the disinfectant broad-spectrum “Univayt” was effective in neutralizing Micromycetes. Starting with the 0.5% concentration solutions it detrimental effect on fungi genera Aspergillus, Penicillium, Fusarium in contact for 30 minutes and completely eliminates them, as evidenced by the absence of fungal growth on the Capek medium. It should be noted that the concentration of disinfectant working directly proportional to the change of its fungicidal properties relative Micromycetes. In our case, disinfectant “Univayt” at 6.0% concentration was the most effective. During the experiment, it was confirmed in diameter crops stunted growth of fungi.
Conclusions and prospects for further research: 1. Investigation of the exposure and concentration of disinfectant “Univayt”, which killed micromyceta in 0.5% at 30 minutes. 2. The effective fungicidal action on fungi genera Aspergillus, Penicillium, Fusarium investigational agent was at a concentration of 2.5% at the 30 minute exposure.
