Purifloh Limited advised that the hospital trial work is ongoing. Isolating the Mycobacterium Tuberculosis ("MTB") from air samples in the in situ environment remains challenging and the Company has still not been able to successfully obtain reliable baseline data. The Company has previously noted the difficulties with rapid contamination of the culture by pathogenic species of mold such as Aspergillus fumigatus and Aspergillus flavus. This still remains a challenge even though the trial venue was shifted to a more controlled environment in a negative pressure room with a single MTB patient. The difficulties of identifying MTB through the culture method have been reported by other researchers due to ".slow growth of M. tuberculosis and the contamination of other bacteria and fungi (Loudon et al. 1969; Macher et al. 1992; Riley et al. 1976)"". The Company is now in discussions with industry experts and exploring alternative means of collecting the air samples and analyzing them. It should be stressed that the lack of desired results is not due to the performance of the Free Radical Generator ("FRG") rather the challenges of isolating MTB to provide a suitable baseline. Literature user does define order of susceptibility to disinfection and sterilization, with the table below showing that bacterial spores are more resistant than mycobacteria. The Aerosol testwork did achieve a single pass kill rate for Bacillus 1Endospores of 99.9598%, so the company retain a reasonable expectation that FRG would kill MTB. The Company would stress the importance of the hospital trials showing the FRG's ability to destroy the pathogenic molds Aspergillus fumigatus and Aspergillus flavus. Aspergillus is an increasing problem within the global hospital environment particularly with immune compromised patients ­ elderly, cancer, HIV and patients undergoing procedures requiring immune suppression such as bone marrow transplant.
