H. influenzae—it ain’t the flu, but it’s still pretty cool

I’ve been thinking about an interesting organism lately, an organism that illustrates some basic principles in science-based medicine.

The organism is called Haemophilus influenzae (H flu), a gram-negative bacterium discovered in the late 19th century. H flu has a great story, both in historic and modern times.

The brilliant microbiologist Richard Pfeiffer isolated H flu from influenza patients in the late 1800′s (hence its name) and for many years, it was believed to be the cause of the epidemic illness, and when the flu pandemic of 1918 hit, researchers worked tirelessly to develop anti-sera against H flu.

But some things weren’t adding up. As thousands died of the flu, doctors were isolating H flu from victims, but also other virulent bacteria such as Streptococcus pneumoniae. Influenza was decimating military camps, and was seriously degrading our ability to fight in WW I, so military bases were a focus of research. Doctors looked for H flu in patients, but could not find it consistently. For example in Camp Dodge, Iowa, an autopsy series showed H flu in only 9.6% of victims.

How not to win friends and influence people

BLOGGER’S NOTE: The incident described in this post is true, although somewhat embellished to protect the names and identities of the innocent, if you know what I mean. This conversation occurred a few years ago at a large national cancer meeting.

The question caught me by surprise.

While attending a large national cancer meeting, I was having brunch with a friend, a colleague with whom I used to work when I was doing laboratory research, someone whom I hadn’t seen in a long time. She and her husband had brought along two of their oldest and dearest friends, whom they had known for decades, as well as another of my former coworkers from my old lab. We were idly chatting away and eating, when one of the occupational hazards of being a doctor presented itself. Tthe conversation drifted to medical topics. And then it came.

“What do you think of Dr. Gonzalez?”

Ah, hell.
