Abstract

The work presents the results of a study on a new disinfectant known as “Aseptobrom” for use in veterinary medicine. It contains didecyldimethylammonium bromide and alcohols as active substances. The laboratory trials showed that the disinfectant had significant antimicrobial activity against Escherichia coli (strain 1257), Staphylococcus aureus (strain 209-P) and Mycobacterium (strain terrae). As a result, it was found that S. aureus was more sensitive than E. coli. When rough, moisture-absorbing surfaces were contaminated with E. coli, disinfection was achieved with a 1% solution (3-hour exposure, disinfectant consumption rate – 0.5 L/m²). In case of contamination with staphylococcus, a 0.4% solution was used. Other specified parameters were not changed. To destroy Mycobacterium, a concentration of 6.0% was required with an exposure of 24 h. Moreover, the disinfectant was applied twice with an interval of 60 min. The consumption rate of the preparation for each irrigation was 0.5 L/m². A study of the corrosion properties of the preparation showed that, in comparison with sodium hydroxide, it has a slight corrosive effect on metal surfaces, in particular on stainless steel and iron test plates.
