Blog 10- Gastrointestinal bug C. difficile on the rise


      For years public health experts have been warning doctors to cut back on the wide scale usage of antibiotics to avoid producing mutant bacteria that are resistant to treatment.  Antibiotics not only kill infectious bacteria, but they can also wipe out good bacteria in the gut leaving a patient prone to catch another nastier disease.  Clostridium diffiicile is a common bacterium that causes gastrointestinal distress that ranges from diarrhea to deadly infections in the colon.  Karen Anderson, manager for infection control and protection at California Pacific Medical Center, believes that C. difficile is the new MRSA, which is a drug resistant staph infection.  C. difficile spreads easily and quickly, especially in the elderly; if the strain becomes resistant like MRSA the only way to get rid of it would most likely be surgery.  Researchers say that the disease is a modern problem due to the widespread use of broad spectrum antibiotics that not only wipe out the viruses, but other healthy bacteria in the gut that helps to fight infections as well.  Hospitals are trying to prevent the spread of C. dificile by monitoring the amount and type of antibiotics they give out to treat the patients.  Scientist are now studying what bacteria is needed by the gut to be healthy, with the hope of inventing a new probiotic to maintain the good bacteria.
            With all of the medical advances that have been made over the centuries people live longer and they tend to be healthier.  A lot of this is thanks to the development of vaccines and antibiotics that protect us from harmful bacteria and viruses, but now partly due to survival of the fittest and partly due to the overuse of these antibiotics bacteria are becoming immune.  It is not just in America with the C. difficile bacteria, but all over the world new resistant strains of bacteria are emerging.  Another example of resistant strains of bacteria is tuberculosis and resistance has become present in malaria.  Some scientist claim that as soon as the first antibiotic was introduced bacterial strains began to form a resistance to it because they can reproduce so quickly, but other scientists say that it is due to the improper use of antibiotics.  Antimicrobial resistance (bacteria, viruses, and some parasites) poses a threat of many diseases becoming uncontrollable, which would halt and reverse the progress made towards reaching the goal of the United Nations Millennium Development Goals set in 2015.  One of the goals is to prevent child deaths from dehydration and lack of nutrients due to chronic diarrhea, caused by gastrointestinal bacteria like C. difficile.  With resistant bacterial infections the cost of health care will increase mainly in developed nations, due to the more expensive means of getting rid of the infection.  Precautions, such as monitoring of the types of antibiotics given and the use of them by the patient, should be taken to prevent the rise of antimicrobial resistance.  If infectious diseases can no longer be controlled dire consequences will arise.
