The use of actinomicetes products in the fight against american foulbrood

Abstract

It is known that actinomycetes actively synthesize products with antibacterial, antifungal, antiviral and antitumoral proprietes. Summary of actinomycetes antibiotics are characterized by a broad antimicrobial spectrum. Antibiotics are widely used on microbial diseases in human and veterinary medicie. Their advantage of actinomycetes is in the relatively low toxicity to humans and animals in comparison with the chemical compounds and the specific action of ability to penetrate the tissues and high activity against pathogens. Scientists from several countries dealing with the isolation of new strains of streptomycetes, which synthesizes substances with antimicrobial properties. Thus, the selection of antibiotic-producing microorganisms isolated from various regions, has been isolated a new strain of streptomicetes summarizing the antibiotic. Object of the research were actinomycetes strains of the genus Streptomyces isolated from soil and kept in CNMN Moldova ASM. Streptomycetes strains are maintained in the laboratory on solid Czapek medium with glucose at temperature +40C. As test strains were used pathogens Paenibacillus larvae, Aspergillus flavus and Aspergillus niger causing American foulbrood and aspergillosis in Apis mellifera.
