What Makes You Sick? On a blustery and frigid evening in early December, Professor Paul Ewald is huddled inside an auditorium with a group of 30 Amherst College students. Another suggests the seasonal variation in births of autistic children is a reason to suspect that an infection during pregnancy induces the disease.

Like most students of science, I was taught that statistical associations are soft science: To back up his arguments, Ewald goes beyond curious associations such as those found for multiple sclerosis and autism, and argues his case from an evolutionary point of view: Diseases such as cancer, heart disease, and even schizophrenia and obsessive-compulsive disorder are too common to be caused primarily by bad genes, Ewald claims.

Natural selection, he says, should have weeded those genes out of the population long ago. Instead, some genes might merely be making people more susceptible to infectious organisms, which are the true culprits of chronic disease … But Ewald is more like a lone wolf than the leader of a pack.

Any mammal would have a selective disadvantage if it tended to destroy itself when invaded by micro-organisms.

The increasing number of people who are color blind to various degrees can be pointed to as an example of the survival of defects, but this does not apply to our response to parasites: Humans have substantially reduced their chances of coming in contact with macro — predators such as tigers; and this security has been with us for at least 10, years — plenty of time for the effect to show itself of no penalty for not being able to distinguish green from yellow.

This is not the case with micro — predators. Polio, diphtheria, syphillis, tuberculosis, and HIV have wrecked havoc on us within the last hundred years. For every smallpox we put down, it seems that ten more species of pathogens rise in its place. It was only in the 19th century that the germ theory of disease began to be accepted; and, even today, genetic tendencies and environmental stresses are the preferred explanations.

In the 19th century, for example, doctors at the University of Vienna hospital had their collegue Semmelweis fired because he cut the maternity death rate of one mother for every eight admissions to one in thirty by having the staff on his ward wash their hands.

In the past few decades, a handful of cancers have been unquestionably linked to infections. Take the case of cervical cancer and the human papilloma virus HPVfor example. The Centers for Disease Control reports that the sexually transmitted virus is responsible for as much as 93 percent of all cases of cervical cancer.

But because most women infected with HPV never develop cervical cancer the CDC estimates that 20 million Americans carry the virusand the cancer takes years to kick in — characteristics very uncharacteristic of infectious disease — figuring out the connection took years.

These and other viruses are responsible for between 15 and 20 percent of all cancers. The rest, say most scientists, can be blamed on rogue genes and non-infectious environmental factors such as diet and smoking. His reasoning, backed up by mathematical calculations, goes something like this: Older people are still subject to natural selection after they stop reproducing because they pass on their care and wisdom to their children and grandchildren as in some societies where grandmothers are responsible for preparing food.

Over many generations, children with grandparents will prevail over children without grandparents whose genes presumably made them more vulnerable to disease.

Studies have shown that people with a gene called APO E4 appear to be more susceptible to both diseases. But Ewald argues that a faulty gene is too prevalent between 10 and 50 percent of a given population carries APO E4 to have been conserved through evolution, and that it is merely making people more susceptible to infection.

An airborne bacterium that infects the respiratory system, Chlamydia pneumoniae, may be one of the real culprits.Microbiology Unknown Lab Report.

UNKNOW BACTERIA LAB REPORT UNKNOWN 36 Introduction The purpose of this lab was to identify two unknown bacteria from a mixed culture. The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics.

HOW TO WRITE AN UNKNOWN LAB REPORT IN MICROBIOLOGY GENERAL UNKNOWN LAB REPORT # 1 Be specific, but do not re write the lab manual.

One way is to mention the names of the materials used and reference the lab manual for the procedure or method.
