Abstract:
Objective To investigate the aerosolized livability,aerosolized quantity and aerosol particle diameter,etc. of phage D29. Methods Phage D29 aerosol was produced in the aerosol test cabinet in negative pressure laboratory. TSI3321 aerodynamic particle sizer spectrometer was used for detecting the diameter of the aerosol particle. Bioaerosol particle median diameter was tested with Anderson six grade microorganism sampler. The aerosolized livability and quantity of phage D29 were determined by the variations of the concentrations and quantities of phage D29 before and after aerosolization.Results The aerodynamic diameter of phage D29 aerosol was 0.872 μm. Bioaerosol particle median diameter was 2.21 μm. The livability after aerosolization for 5,15,30,45,and 60 min were 89.78％,77.19％,48.86％,33.99％,30.12％,respectively. The aerosolized quantity of phage D29 was 232 μl/min. Conclusion The characters of the aerosolized livability,aerosolized quantity and aerosol particle diameter of phage D29 were thought to be suitable for further research into aerosol inhalation treatment of Mycobacterium tuberculosis infection in animals.
