Hospital disinfection

Hospital trials will be instigated

From Mr S. Blum, MRPharmS

Michael Richards incorrectly assumed (PJ, 13 August, p194) that “Hospital sterilisation” was the heading that I had placed on my letter entitled “New discovery” (PJ, 30 July, p139). On the basis of this false assumption Professor Richards then goes on to denigrate both my knowledge of microbiology (acquired in the pharmaceutics department of Bradford University) and the contents of my letter.

All my statements as to the efficiency of my bactericidal formulation against methicillin resistant Staphylococcus aureus and a number of other life-threatening hospital pathogens are derived from a UK accredited microbiology laboratory which has certified its results.

Its results show that D+10, ie, 100 per cent of the pathogens named (to use Professor Richards’s D for 90 per cent kill), died within an exposure time of 10 minutes at 22C.

Further exciting results have emerged from the microbiology laboratory relating to my bactericidal compound’s activity, which will be made public after their inclusion in my patent application filed on 3 March 2005.

I have notified the microbiology laboratory of Professor Richards’s assertion “that it is not possible to determine a 100 per cent kill of micro-organisms” and I await its reply. In the meantime I will instigate hospital trials as I believe that the proof of the pudding is in the eating.
