Composition of Bacteriophages for Therapeutic and Prophylactic Use in Monkeys

Area of Science:

• Veterinary Medicine
• Microbiology
• Primate Health

Background:

• Rhesus monkeys are vital laboratory animals, necessitating effective control of bacterial infections.
• Clinically significant bacteria such as E. coli, Staphylococcus aureus, Klebsiella spp., and Proteus spp. pose a threat to primate health.

Purpose of the Study:

• To identify prevalent pathogenic and opportunistic bacteria in rhesus monkeys.
• To develop and evaluate a bacteriophage-based therapeutic agent for bacterial infections in these animals.

Main Methods:

• Microflora analysis of healthy and sick rhesus monkeys.
• Isolation and characterization of virulent bacteriophage strains.
• In vivo safety and efficacy testing of bacteriophage composition in monkeys.

Main Results:

• Identified E. coli, S. aureus, Klebsiella spp., and Proteus spp. as key bacterial pathogens.
• Selected four virulent bacteriophage strains with broad lytic activity against isolated bacteria.
• Confirmed the safety of the bacteriophage composition and detected phage-specific DNA in treated monkeys.

Conclusions:

• Bacteriophage therapy presents a promising approach for managing bacterial infections in rhesus monkeys.
• The developed phage composition is safe and shows potential for clinical application in primate care.
