Viruses and Diseases
We are there food. Those germs of the past that best converted our bodies into their own propagation are the germs of the present. Those germs of the present that best convert our bodies into their own propagation will be the germs of the future. Why should we care about the prospects of one particular germ over another? Aren’t they all just plain bad? The answer is no. We can never get rid of them all. Their future is our future. If their future goes one way, we will be relatively healthy; if it goes another, we will be sick or even dead. Neglect of the germ’s-eye view of the world is not restricted to the average person; it extends to medicine as a whole for most of its history (Ewald 9). Scientists have proven that some viruses are to blame for certain diseases not the genes that have been inherited.
Artherosclerosis is characterized by fatty deposits that develop as streaks inside the lining of arteries and some streaking can be found in teenagers and then by an increasing proportion of the population from then on. If you were to ask the experts what causes arteriosclerosis the answer would depend on the expert. Researchers do not agree on the causation but they have agreed on possible risk factors such as smoking, a high fat diet, high cholesterol levels, high blood pressure, high iron levels, inflammation and bad genes. None of which appear to be the primary cause because if you were to eliminate one possible cause you should eliminate the disease. Many researchers have begun to think that many diseases including cancers originate as a composite of risk factors and that approach does not make sense because it suggests that Human arteries are so fragile that any one or combination of these risk factors can cause life threating damage to it. Such a weakness would have been breed out or caused the extinction of the human species long ago. Besides the fact that half of the people that come down with the disease don’t have any of the risk factors (Ewald 157).
In Finland incendance of heart disease is ranked highest in the world that is why many labs there are working cooperatively on that problem. To assess the presence of infection after heart attacks a large sample of blood serum was collected by the University of Helsinki and distributed to several labs. When Maia Leinonan of the National Public Health Institute of Helsinki analyzed the samples for Chlamydia she found that 70% had antibodies for it which was significantly higher than the serum from the control group that had not had heart attacks. And the only species of Chlamydia that could produce such a high antibody rate was Chlamydia Pneumoniae it is a bacteria that is responsible for 1 of every 5 incidence of pneumonia and there were no recent incidence of infection in any of the patients. The response of the scientific community to the hypothetical possibility that the organism at the site of arthersclerotic damage in the artery is actually doing the damage or triggering an immunological response that does the damage was met with mild fascination to strong ridicule (Ewald Evolution 178).
In 1992 while studding sections of arthersclerotic plaques from arteries removed during bypass operations the South African researcher Alan Shor found the bacteria Chlamydia Pneumoniae. He then sent samples to the lab at the University of Washington in Seattle. And after performing several tests confirmed that it was indeed Chlamydia Pneumoniae.
But such evidence was not enough to satisfy the many critics in the scientific community who prefer to side with the alternative hypothetical research involving diet or genetics the two sides that most researchers have taken (Ewald 109).
After several decades and billons of dollars a common gene has not been found. And the researchers that favor the good diet hypothesis have yet to make up their minds. First they have stated a low fat and low cholesterol diet was the answer. Later stating that fats are necessary, that there are good fats and bad fats as well as good cholesterol and bad cholesterol. All the while people who follow these strict diet and exercise regimens for many years and are apparently in excellent health are
