Jules Henry QUOTES / QUOTATIONS
After clearly establishing the role of the louse, I demonstrated the detailed mechanism of transmission. Two factors are involved: man and the louse.
Quotation of Jules Henry
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.
Quotation of Jules Henry
During the years that followed I undertook with Conseil and Alfred Conor, and later with Georges Blanc, a more detailed experimental study of the disease and the conditions of transmission.
Quotation of Jules Henry
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.
Quotation of Jules Henry
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.
Quotation of Jules Henry
From the very beginning of the Great War steps were taken, on my instruction, to institute medical control of troops in North Africa.
Quotation of Jules Henry
I cultivated lice on the macaco, which I then transported to other macacos. The latter became infected and subsequently proved to be vaccinated against a test inoculation of the virus.
Quotation of Jules Henry
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.
Quotation of Jules Henry
I finally demonstrated that typhus infection is not hereditary in the louse.
Quotation of Jules Henry
I was born, first studied medicine and undertook my first research work in a French province from which typhus had disappeared since 1814.
Quotation of Jules Henry
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.
Quotation of Jules Henry
I wondered if there was not, below the very slight susceptibility of the guinea pig, an even lesser degree in which the only sign of infection was the virulence of the blood during the period when more susceptible animals showed signs of the characteristic fever. This was indeed the case.
Quotation of Jules Henry
In June of 1903 I was determined to carry out a preliminary study. At that time typhus was raging in a native prison, 80 kilometres South of Tunis, Djouggar.
Quotation of Jules Henry
In spite of this, once admitted to the general ward the typhus patient did not contaminate any of the other patients, the nurses or the doctors.
Quotation of Jules Henry
It did not seem likely that I was destined to undertake research on typhus.
Quotation of Jules Henry
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.
Quotation of Jules Henry
Lebailly and I then went on to demonstrate that inapparent primary infection typhus, which is exceptional in inoculated guinea pigs, is the only form which the disease takes experimentally in the rat and the mouse.
Quotation of Jules Henry
Most of the doctors in the Tunisian administration, especially those in country districts, contracted typhus and approximately one third of them died of it.
Quotation of Jules Henry
My arrival in Tunisia placed me immediately in contact with typhus. Ten days after my arrival, at the beginning of January 1903, I saw a few cases in natives living in a suburb of Tunis.
Quotation of Jules Henry
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.
Quotation of Jules Henry
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.
Quotation of Jules Henry
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.
Quotation of Jules Henry
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.
Quotation of Jules Henry
The knowledge of the preventive properties contained in serum from convalescent typhus patients led me, with Conseil, to use serum taken from children cured of measles to prevent this disease.
Quotation of Jules Henry
Thus my research opened a new chapter, subpathology, which is doubtless a vast field where almost everything remains to be discovered.
Quotation of Jules Henry
We have known for a long time that primary infection of typhus confers immunity in man in almost all cases and that this immunity lasts a lifetime.
