Who said: “The path towards sustainable energy sources will be long and sometimes difficult. But America cannot resist this transition, we must lead it... That is how we will preserve our planet, commanded to our care by God. That’s what will lend meaning to the creed our fathers once declared.”

Malaria Quotes (10 quotes)

Had there not been in zoology men who devoted themselves to such seemingly unimportant studies as the differentiation of the species of mosquitoes, we should not have been able to place on a firm foundation the aetiology of malaria and yellow fever.
From address, 'A Medical Retrospect'. Published in Yale Medical Journal (Oct 1910), 17, No. 2, 65.

I can think of a few microorganisms, possibly the tubercle bacillus, the syphilis spirochete, the malarial parasite, and a few others, that have a selective advantage in their ability to infect human beings, but there is nothing to be gained, in an evolutionary sense, by the capacity to cause illness or death. Pathogenicity may be something of a disadvantage for most microbes…
In 'Germs', The Lives of a Cell: Notes of a Biology Watcher (1974), 90.

I have failed in finding parasites in mosquitoes fed on malaria patients, but perhaps I am not using the proper kind of mosquito.
Letter to his wife (14 Aug 1897). In Memoirs, With a Full Account of the Great Malaria Problem and its Solution (1923), 221.

I must … explain how I was led to concern myself with the pathogenic protozoa. … I was sent to Algeria and put in charge of a department of the hospital at Bone. A large number of my patients had malarial fevers and I was naturally led to study these fevers of which I had only seen rare and benign forms in France.
From Nobel Lecture (11 Dec 1907), 'Protozoa as Causes of Diseases', collected in Nobel Lectures, Physiology or Medicine 1901-1921 (1967, 1999), 264.

In the tropical and subtropical regions, endemic malaria takes first place almost everywhere among the causes of morbidity and mortality and it constitutes the principal obstacle to the acclimatization of Europeans in these regions.
From Nobel Lecture (11 Dec 1907), 'Protozoa as Causes of Diseases', collected in Nobel Lectures, Physiology or Medicine 1901-1921 (1967, 1999), 264.

Lately, however, on abandoning the brindled and grey mosquitos and commencing similar work on a new, brown species, of which I have as yet obtained very few individuals, I succeeded in finding in two of them certain remarkable and suspicious cells containing pigment identical in appearance to that of the parasite of malaria. As these cells appear to me to be very worthy of attention … I think it would be advisable to place on record a brief description both of the cells and of the mosquitos.
In 'On Some Peculiar Pigmented Cells Found in Two Mosquitoes Fed on Malarial Blood', British Medical Journal (18 Dec 1897), 1786. Ross continued this study and identified how malaria was transmitted.

Malaria which is almost unknown in the north of Europe is however of great importance in the south of the Continent particularly in Greece and Italy; these fevers in many of the localities become the dominant disease and the forms become more grave.

This day relenting God
Hath placed within my hand
A wondrous thing; and God
Be praised. At His command,
Seeking His secret deeds
With tears and toiling breath,
I find thy cunning seeds,
O million-murdering Death.
I know this little thing
A myriad men will save.
O Death, where is thy sting?
Thy victory, O Grave?
Poem he wrote following the discovery that the malaria parasite was carried by the amopheline mosquito.
From a privately printed book of verse, anonymously published, by R.R., In Exile (1906). As cited by S. Weir Mitchell, in 'The Literary Side of a Physician’s Life—Ronald Ross as a Poet', Journal of the American Medical Association (7 Sep 1907), 49, No. 10, 853. In his book, Ronald Ross stated “These verses were written in India between the years 1891 and 1899, as a means of relief after the daily labors of a long, scientific research.”

When the morning breezes blow toward the town at sunrise, if they bring with them mists from marshes and, mingled with the mist, the poisonous breath of the creatures of the marshes to be wafted into the bodies of the inhabitants, they will make the site unhealthy.
Vitruvius
In De Architectura, Book 1, Chap 4, Sec. 1. As translated in Morris Hicky Morgan (trans.), Vitruvius: The Ten Books on Architecture (1914), 16.

[The parasite that causes malaria] edges through the cells of the stomach wall of the mosquito and forms a cyst which grows and eventually bursts to release hundreds of “sporozoites” into the body cavity of the mosquito … As far as we can tell, the parasite does not harm the mosquito … It has always seemed to me, though, that these growing cysts … must at least give the mosquito something corresponding to a stomach-ache.
In The Prevalence of People (1955, 1962), 165.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
