Abstract:
Objective To investigate the feasibility of applying nanotechnology against M.tuberculosis growth.Methods Chitosan-antisense ODN nanoparticles were prepared by complex coacervation method.Varied amount of ODNs and chitosanODN nanoparticles were added to the cultures and the growth of the bacilli was monitored.Results The nanoparticles were composed of(35.6±0.9)% ODN and(64.4±0.9)% chitosan.Compared to the free ODN,antisense nanopartilces were more effective in inhibiting the proliferation of M.tuberculosis.Antisense nanoparticles decreased growth by(2.8±0.1)CFU/ml at concentration of 4/μmol/L.Conclusion Chitosan-ODN nanoparticles were more effective in inhibiting the growth of M.tuberculosis than free ODN.
