- Abstract
The identification of new probiotics as antimicrobial agents is important in connection with the evolution of the antimicrobial resistance of pathogenic bacteria as a result of the intensive use of antibiotics. In experiments on gnotobiotic chickens, the ability of monocultures and associations of bifidobacteria, lactobacteria and bacteroides to inhibit and replace pathogenic bacteria - Escherichia and Salmonella - was tested. It has been established that monocultures and combinations of beneficial bacteria in a single dose (1 million bacterial cells for each animal) do not significantly influence the inhibition of pathogenic microbial agents. In order to eliminate them from the intestines, a new scheme was applied, which provided the additional administration of beneficial bacteria in a dose of 100 billion microbial cells for 15 days, over a day. The administration of beneficial bacteria according to the proposed scheme resulted in the obvious suppression of the pathogens of colibacteriosis and salmonellosis in experimental chickens. Also, the tested microorganisms positively influenced the growth and development of experimental animals and contributed to the general resistance of the organism and protection against gastrointestinal diseases. The obtained results can be applied not only to poultry industry, but also to the captive-breeding of pet and wild birds.
