Operation Big Itch, in 1954, was designed to test munitions loaded with uninfected fleas ( Xenopsylla cheopis ).
2.
Nonetheless, Pulex irritans, the human flea, is a much less efficient vector of plague than the rat flea Xenopsylla cheopis.
3.
He discovered and named the vector flea, " Xenopsylla cheopis ", also known as the oriental rat flea, in 1903.
4.
The oriental rat flea, " Xenopsylla cheopis ", is a vector of " Yersinia pestis ", the bacterium which causes bubonic plague.
5.
Bubonic plague is an infection of the lymphatic system, usually resulting from the bite of an infected flea, " Xenopsylla cheopis " ( the rat flea ).
6.
He also discovered and named the vector flea, " Xenopsylla cheopis " ( Rothschild ), also known as the oriental rat flea, at Shendi, Sudan, on an expedition in 1901, publishing his finding in 1903.
7.
From time to time plagues such as bubonic plague, caused mainly by rat fleas ( Xenopsylla cheopis, a parasite found on brown rats ), " red " dysentery and other scourges killed a great deal of Flensburg's population.
8.
In September 1954, at Dugway Proving Ground in Utah, the E14 was again used in a series of tests known as " Operation Big Itch " . ( " Xenopsylla cheopis " ) were loaded into the E14 and air-dropped over the proving ground.
9.
Four of the five patients had severe pharyngitis and submandibular lymphadenitis . " Yersinia pestis " was isolated from the camel's bone marrow, from the jird ( " Meriones libycus " ) and from fleas ( " Xenopsylla cheopis " ) captured at the camel's corral.
10.
"' Paul-Louis Simond "'( 30 July 1858 & ndash; 3 March 1947 ) was a French physician, chief medical officer and biologist whose major contribution to science was his demonstration that the intermediates in the transmission of bubonic plague from rats to humans are the fleas " Xenopsylla cheopis " that dwell on infected rats.
