I went on a tangent and was researching Y. pestis. And what did I find…
Charles Rothschild(9 May 1877 – 12 October 1923), entomologist, discovered and named, the Bubonic plague vector flea, Xenopsylla cheopis, also known as the oriental rat flea, which he collected at Shendi, Sudan, on an expedition in 1901, publishing his finding in 1903.
I'm sure they did nothing but good with that kind of information.
Note the tribute to Egyptian pyramids, X. cheopsis
