I was unaware of the discovery of the organism that caused the "Spanish" flu. [I lost a grandmother and greatgrandmother to this disease; more people were killed by this disease in one province of India than died in both sides in World War I.]

I have heard a number of well informed experts opine that much of the virulence of this outbreak was due to a bacterium [in the Haemophilus genus as I recall] which occurred along with the influenza virus. Do you know if such an association was found and, if so, were any LD50 testings done?

Sorry, don't know about the bacteria angle or any other conclusions.
