Composition of Bacteriophages for Therapeutic and Prophylactic Use in Monkeys

Keeping rhesus monkeys as laboratory animals requires timely prevention and treatment of infections, including diseases of bacterial etiology. Based on our own studies of the microflora of healthy and sick monkeys, as well as analysis of published reports, we identified clinically significant representatives of pathogenic and opportunistic bacteria: E. coli, Staphylococcus aureus, Klebsiella spp., Proteus spp. The isolates of these bacterial species and genera circulating in monkeys kept in the enclosure were isolated, four virulent bacteriophage strains with a wide spectrum of lytic activity against these isolates were selected and newly isolated. The composition based on virulent bacteriophage strains was tested on monkeys with assessment of its safety and its dynamics of detection of phage-specific DNA.
