Midyk S. Development of Disinfectant of Combined Action

The thesis is devoted to the development, study and introduction of effective chemical means of preventive measures of infectious and invasive animal illnesses in Ukraine.A recipe of new disinfection preparation is worked out. An aproximate bactericidal breeding, phenol coefficient, albuminous index and disinfection action of preparation are determined. Its effective bactericidal concentrations are set on E. coli and S. aureus on the objects of test and in the production conditions; its tuberculocide effect was proved on Mycobacterium of bovis; its viruscide effect on the virus of the Newcastle bird's desease of vaccine culture La Sota is studied. The method of distinguishing of the efficiency of surfaces disinfecting is improved, which allowed to prevent from the dilution of virus containing material. The preparation is effective for disinvasion of stock-raising apartments in case of nematodosis. An effective concentration for an insecticide action on Musca domestica has been set and its prolongationhas been proved. Certain lethal toxic doses of preparation have been determined; its cumulative, irritating, skin resorptive sencitilazing effects have been checked. The macroscoric histological changes of organs of laboratory animals after the administration of working and lethal doses of preparation have been shown. The corrosive effect of preparation on metals has been studied. The presence of tailings of preparation on surfaces after disinfection is tested.
