Abbe took over for Zeiss.

According to Abbe’s calculations the wavelength of light determines the light microscope’s ability to see tiny objects and the magnification factor can’t be much more than 1,000. A number of parasites that had not, previously, been visible were identified. After Zeiss died in 1888, Abbe became the head of the company and, ahead of his time, he introduced an 8 hour work day, pensions and holiday and sick pay.

Chapter Two: The Late-19th Century

John Snow and diarrhea in 1854 

The son of a York farmer, Snow had moved to Newcastle, a northern English city located on the Tyne River when he was 14 and was an apprentice to an Apothecary- surgeon for 9 years.  He then moved to London where he studied medicine.  He became a member of the Royal College of Surgeons ten years before “the first case of Asiatic cholera” came to “the great city.” The illness arrived in the body of a seaman who died a few hours after the illness “seized” him.  The sailor had been working on a steamer where “the disease was prevailing.” Shortly after the man’s death his body was removed from the room he had been renting and another man moved in.  Eight days later the newcomer developed severe diarrhea and fever—cholera.  Snow discussed their illness in a medical paper and argued cholera was not airborne.  “He also wrote about the neighborhood keeper of a coffee shop who served glasses of water from the Broad Street pump along with meals.  She knew of nine of her customers who had contracted cholera.”

Mostly a vegetarian Snow “occasionally” drank wine when he was older, but he continued to have “faith in the temperance cause.”  He dressed plainly, never married, “and found every amusement in scientific books, and simple exercise.”  He was “full of humorous anecdotes” and told them in an irresistibly droll style.  His husky voice “rendered first hearings from him painful,” but when he guffawed “his good natured face laughed in every feature.”

Mosquito eradication

“Lien Jih-ching (連日清) is a specialist in mosquito-borne diseases and helped eradicate malaria in Taiwan by reducing the number of endemic cases from more than 1 million to zero within a decade,” Chen said, adding that Lien helped Taiwan become the first nation in the world to be declared “malaria-free” by the WHO in 1965.

“People call me the ‘mosquito man,’” said Lien, who is nearly 90 years old.

Lien also helped to significantly reduce the prevalence of malaria in Sao Tome and Principe — an island nation in western Africa — as depicted in the second part of the documentary.

“The prevalence of malaria was about 40 percent in 2000 … after we applied mosquito prevention measures, the numbers of patients hospitalized for malaria in Sao Tome and Principe dropped to zero in 2003,” Lien said in the documentary.

The use of an insecticide called dichlorodiphenyltrichloroethane is credited with the eradication of malaria in Taiwan, but it was not as effective in Sao Tome and Principe, Lien said, adding that he instead used alpha-cypermethrin, which had proven effective in southern Taiwan against dengue fever.

The story of Lice and ticks is on the web site but not in the book.

LICE

In the 1800s some claimed the river flowing past Rouen smelled bad when too many in Paris flushed at the same time.  Rouen borders the Seine River and is 80 miles closer to the ocean than the city of lights.  It is the capital of Normandy, is known for the Monet paintings of its Gothic cathedral, and is the home of the ancient marketplace where Joan of Arc was burned at the stake. 

It’s also the town where Jules Noelle was born in 1866.  At age 29, after he studied in Paris and became a doctor.  Then he moved back home and married 21 year old Alice Louise Avice.  He got a job at the local medical school, but his position was not tenured, his colleagues were reluctant to accept his “wonky” Parisian belief that germs caused disease, and he was unable to hear well enough to use a stethoscope.  His career was going nowhere when the French government came looking for doctors for Tunisia, their recently conquered colony.  Jules’ brother was offered a job in north Africa and he declined, but 36 year old Jules applied for the position and was hired. 

In Tunisia an illness called Typhus was a problem each winter. (The name comes from the Greek word tuphos or stupor.)  People in the “overcrowded prisons, asylums, and tent villages” ran fevers, became confused, and sometimes died. When Jules arrived an outbreak “was raging in a native prison 80 kilometers south of Tunis/” The doctor in charge of health care was planning to visit the area and Jules asked if he could accompany him.”  The night before the trip Nicolle coughed up blood and he decided to stay behind.  The chief doctor and his servant, visited the prison, spent the night, contracted typhus and both died.

As one of the now senior physicians, Nicolle decided to learn more about the illness.  He visited a hospital, and recalled stepping over the bodies of typhus patients who were awaiting admission to the hospital and had fallen exhausted at the door.”  He noticed that sick people “spread the contagion “to others in the hospital waiting room but stopped contaminating others as soon as they bathed and dressed in a hospital uniform.”  Nicole figured the clothes—more specifically the lice that lived in the clothes, had to be the vector that spread the disease.

He injected a chimpanzee with blood from an ill patient and a day later the chimpanzee was running a fever and was prostrate. “Nicolle then injected a toque macaque (Macaca sinica) with blood from the ill chimpanzee and two weeks later the macaque got sick.  He transferred the lice that were feeding on sick macaques to other macaques and they got sick.  Nicolle was unable to culture the offending organism in agar or broth, but he published his findings in 2009 and remained in Tunis where he became an important bacteriologist.  As he aged Nicolle became philosophical and a nature lover.  His deafness got worse, it was hard to be social, and he spent much of his non research time writing and publishing three novels:  The Two ThievesThe Pleasures of Boredom, and Marmouse and his Guests. He was “Captivated by the town of Carthage” built near the ruins of a once influential and affluent city.  Noelle was known to hold court and sip mint tea in the village of Sidi Bou at a café that overlooked the town.  Carthage had once been the home of Hannibal the general who marched his troops and elephants across the Alps and almost reached Rome.  Between 264 and 146 BC the ancient city-state fought three bloody wars with Rome. During the third war the Carthaginian troops were defeated and the town was thoroughly destroyed.     At age 62 Noelle was awarded a Nobel Prize. 

The germ that causes typhus belongs to a “type” of bacteria that replicates inside other cells but doesn’t grow on agar.  Called Rickettsia, this type of bacillus enters the body through a skin scratch, gets into the blood stream, and infects the cells that line the arterial walls.  The first illness proved to be caused by this type of bacteria was Rocky Mountain spotted fever.  Infected people have headaches, fever, and a rash.  Some become quite ill, and a few die.  The name—Rocky Mountain fever–is a bit misleading because the disease affects people in many parts of the U.S.  The groups of bacteria that only replicates inside cells are called Rickettsia after Thomas Rickets, a small town Illinois boy who showed how Rocky Mountain spotted fever is spread.  As a young researcher Rickets spent four years working mostly alone and separated from his young family.  He pitched a 10 by 10 foot tent in a hospital yard in the Bitter Root Valley of Montana, in a location where the population of ticks increased when the snow melted in spring.  Rickets spent much of the research years catching and studying the vector that he thought probably spread the disease.  One of the human families Rickets studied lived on a farm where large number of ticks thrived around the house, on trees, and on the ground.  At one point, Rickets stained a sample of blood from a sick boy who had been bitten multiple times.  Examining the slide Rickets saw the gram-negative bacillus that caused the illness.    He was the first to identify the organism, and in 1910 he wrote a medical paper describing his findings.  His discovery made him famous and later that year he went to Mexico to look for the organism that caused typhus.  In the process of his research he developed typhus–and he died.

In 1930, the year after Nicolle won the Nobel Prize, Paul Müller, a Swiss biochemist working for the pharmaceutical company Geigy, discovered that dichlorodiphenyltrichloroethane (DDT) was highly effective for killing lice and other insects and seemed to be safe for man.   Muller had become interested in chemistry when he was a high school student.  As a teenager he “was often mocked by his peers and called, “The Ghost,” due to his thin and pale appearance”  In later life he owned “a home in the alps, tended a small fruit farm, and took the children on  early morning nature walks. In 1948 Muller was awarded a Nobel Prize.  After it was discovered DDT was widely used in Europe and elsewhere and Typhus stopped being a major problem.  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2819868/
