In two of my earlier articles "Little lively chemists- part I and part II" we have seen that bacteria are the tiniest of the living beings. They carry out a very wide range of biochemical reactions. Some of them trap sunlight and yield food for others to eat. In this process they release oxygen which makes it possible for us all to breathe. There are bacteria which fix nitrogen from the atmosphere. Some of the bacteria release methane whch can be useful as a clean and green renewable biofuel. Seems they are the angels making our life possible and richer.
But life is never so simple. The angelic actions outlined so far in the two articles indicate only one side of the story. The other side is brutal. There are bacteria that kill a large number of people even today, despite all our antibiotics. They are the pathogens giving diseases like - tuberculosis, typhoid, meningitis, bacterial dysentery, and syphilis to name a few. In this article I am just going to acquaint you with the menacing activity of the bacteria causing tuberculosis. You will shudder when you appreciate the gigantic scale it is operating on. The bacteria causing tuberculosis are called Mycobacterium tuberculosis. If you wish please take a look at a T.B. causing single bacterium stained (colored with chemicals in biology lab) follow please this link - http://www.sanger.ac.uk/Projects/M_tuber... Tuberculosis kills according to World health Organization's estimate 1800000 (i.e. 1.8 million) people every year or almost 5000 people every day. To give you more concrete idea 1800000 people means almost the entire voting population of a state like Texas or Florida in US. If stricter measures are not taken against T.B. world over, then it is feared that 100 million more people will get infected in another 15 years with this disease and one third of them will die of the disease. Every second, a person is getting infected with T.B. and one third of the entire world's population is infected at this moment. Many people especially in the first world countries tend to think that only less educated, poor people from developing countries fall prey to this disease. This is not essentially true. The complacence has allowed T.B to reach such proportions where it is now beginning to threaten those countries, which believed it does not exist. Kindly read a story of a highly qualified person a Pharmacy graduate with an M.Phil and M.B.A. in Marketing, residing in a developed country. http://www.stoptb.org/mystory.html#I%20a...
