lot of work to be done on these pages, so thanks for the help. The main microorganism page is almost embarrassingly sparse, if you had some time to expand it, that would be great.    
 :By the way, if you are going to edit more science articles in the future you will find this tool very useful, it creates formatted references from PubMed ID numbers. Saves you a lot of time. All the best    
 No problem, I'm always glad for a bit of extra help with out-of-the-way subjects.    
 :Thanks again for your help with this, if you have time could you read through my expanded version of the genetics section and see if this is too technical for a general reader?
