Bacteria evolve just like all organisms, just faster because their genome (all their DNA) is smaller than mammals. When we take antibiotics, the
chemicals kill off all bacteria in our body including the normal skin and gastrointestinal flora. Some of the bacteria have genes encoding products
which allow them to live in the face of the antibiotics, most of the time these resistant intruders are just killed off by the bodies own immune
system. Sometimes however these resistant bacteria survive. They may not be a problem at the time but become one later, when you get sick again or
take another antibiotic giving them another selective advantage. Bacteria in your (all animals) intestines are exposed to antibiotics most often
because most antibiotics are taken orally. The problem is not that we take antibiotics (although there are issues with people and animals taking too
much or not finishing their antibiotics when prescribed as well), antibiotics are a medical necessity it would seriously SUCK, to go back to the days
when we lacked these drugs. However in the last 20 years bacteria have become increasingly resistant to these chemicals. Now there were scientists who
in the 1970's proclaimed this to be a problem, but they were ridiculed and laughed at, and infectious disease was proclaimed dead. Well guess what
they were right. NOW MRSA- methicillin resistant Staphylococcus aureus, is common hospital infection, happen ALL the time. So what you may say that it
is resistant to one antibiotic no big thing, well it is because the gene which encodes this causes it to be resistant to other antibiotics as well.
Recently this bacteria has become resistant to vancomycin (the last antibiotic available to fight it). When people get infected with this bacteria and
it is now resistant to vancomycin they lose limbs and or die (also the CDC gets involved). Since the first scientists came forward in the 70's others
have made more dire warnings, all of which unheaded, so now MORE types of bacteria; Clostridia genera, E coli, Klebesia genera and others many others
including the bacteria causing sexually transmitted diseases like gonorrhea and syphilis. Pharmaceutical companies (a true evil empire), know about
this and refuse to manufacture new antibiotics, not updated versions of old drugs, which mean quick cash flow for these companies but actual NEW
drugs. The politicians in this country know about this and really do not care, they do not for example offer (real) finical incentives for these
companies to produce these drugs. Meanwhile people are suffering and dying, or course most of them are the very old, and sick or the very young and
poor, hey they don’t vote so in their minds do they really exist? Furthermore the current administration cut funding for the CDC. Yes they increased
the bioterriosm budget but that money is not used to combat problems with everyday bacteria. One day soon however we will begin to see even bigger
problems, more disturbing health concerns, even worse than the one cited in this article. If this problem is not addressed we will return to the days
with people dying of simple urinary track infections, or sore throats.
