It did not seem likely that I was destined to undertake research on typhus.

The fact that I was fortunate enough to escape contagion, in spite of frequent, sometimes daily contacts with the disease, was because I soon guessed how it spread.

The discovery that I soon made that the guinea pig was also susceptible to infection made it possible for me, from the third year on, to preserve the virus on this animal.

From the practical point of view, the susceptibility to infection of the guinea pig proved to be the most useful step forward. Today, all laboratories use this animal for preserving the virus.

I was less successful in my attempts to effect preventive vaccination against typhus by using the virus and in trying to produce large quantities of serum using large animals.

My first attempts to transmit typhus to laboratory animals, including the smaller species of monkeys, had failed, as had those of my predecessors, for reasons which I can easily supply today.

I finally demonstrated that typhus infection is not hereditary in the louse.

Just as the only reservoir for the typhus virus in nature is provided by man, so the only vector of infection is the louse. The bite of the louse is not virulent immediately after the infecting meal. It becomes so only towards the 7th day following infection.

Even if it had not been possible to reproduce the disease in animals and consequently to verify the hypothesis, this simple observation would have been sufficient to demonstrate the way in which the disease was propagated.

Most of the doctors in the Tunisian administration, especially those in country districts, contracted typhus and approximately one third of them died of it.

Of all the problems which were open to me for study, typhus was the most urgent and the most unexplored. We knew nothing of the way in which contagion spread.

I demonstrated the characteristics of experimental fever. It appears after an incubation period which is never less than five days. It follows the same pattern as natural fever in man, but is of shorter duration and less pronounced.

At the time when I was conducting my research there was no known method for taking the guinea pig's temperature. I demonstrated a technique which is now widely used.

It did not seem likely that I was destined to undertake research on typhus.

Corporate partners help UNICEF fund our programmes for children, advocate with us on their behalf, or facilitate our work through logistical, technical, research or supply support.

There are many experiments and a great deal of research that can be performed on the station that make a difference in our lives and we are committed to supporting this important vocation.

From the beginning, the series has been story driven - I began with a story idea - but research feeds it.

This invisibility, however, means that the opportunities for creative research are infinite.

Research is of considerable importance in certain fields, such as science and history.

While I recognize the great value and importance of prescription drugs and strongly support a continued U.S. focus on pharmaceutical research and development, our nation's seniors cannot be asked to subsidize the drug costs of other wealthy industrialized nations any longer.

Harvard is first and foremost a university and not a consulting operation, and our job here is to teach and to research and to create knowledge on Asia in conjunction and in cooperation with scholars as well as with political, intellectual, and cultural leaders in Asia.

I did as much research as I could and I took ownership of this illness, because if you don't take care of your body, where are you going to live?

While advances in scientific research have led to some new and exciting treatments that have enlarged and enhanced the quality and length of human life, we must not lose sight as to what we are trying to accomplish.

I was much involved in the development of the spark chamber as a practical research tool.

You see, I used to do a certain amount of market research by going to the local drugstore and seeing what the truck drivers would put up. Now it's all just copies from the latest best-seller list and damn little of anything else.

When I began, I thought that the way one should work was to do all the research and then write the book.

Advances in science and medical research and public health policies have meant that life expectancy for Australians is one of the highest in the world.

As long as I had easy access to psychedelics at the government-sponsored research project, most of my energy went into psychedelic sessions.

I basically did all the library research for this book on Google, and it not only saved me enormous amounts of time but actually gave me a much richer offering of research in a shorter time.

I think genetic research is a fascinating and fertile area.

The 150th anniversary of Penn State will highlight what is important and good about this distinguished institution and the fine people and research that it produces.

A novel usually takes me two years. A year to research and plan and dream. Then a year to write.

Modern medical advances have helped millions of people live longer, healthier lives. We owe these improvements to decades of investment in medical research.

We said in our 21st Century Party paper there are 61 mosaic groups, which the market research people use as different socio-economic categories and half of our members come from just five of those groups and that is very narrow - too narrow.

We don't ask research to do what it was never meant to do, and that is to get an idea.

I think that we're foolhardy to not be engaging in federal funding of stem-cell research in the most aggressive way we possibly can.

One hundred percent of our earnings are reinvested in the company, and a great deal of that goes to research.

Manufacturers account for nearly 60 percent of all industrial research and development.

As we begin this debate, I am confident that we will hear the supporters of this bill argue in the name of Ronald Reagan that this research is consistent with his long-held views about the sanctity of life.

Some studies show that women can be better money managers than men because they tend to be more conservative and do their homework. Men tend to take more risks without the research.

Think on a 50-year scale, which is a much more natural time-scale for global warming. The US is right now spending about 200 million dollars annually on research into renewable energy.

In the war, most young men were inducted into the armed forces at the age of 17. A group of students was permitted to attend university before taking part in wartime research projects.

Any setting can potentially acquire this vividness. It slowly arrives during the period of research, until it is as immediate to me as my own real surroundings.

Right now I am doing my residency in orthopedic research.

I wouldn't say I'm a method actor. I do research when I feel I don't have enough experience for the part I'm playing.

Research and development needs permanent tax credits to build the technology that spurs our growth. But no government programs alone can get America's students to study more science and math; parents must push and help their children to meet this goal.

For, behind the scenes, halfway around the world in Mexico, were two decades of aggressive research on wheat that not only enabled Mexico to become self-sufficient with respect to wheat production but also paved the way to rapid increase in its production in other countries.

The outcome of any serious research can only be to make two questions grow where only one grew before.

An investigator starts research in a new field with faith, a foggy idea, and a few wild experiments. Eventually the interplay of negative and positive results guides the work. By the time the research is completed, he or she knows how it should have been started and conducted.
