Can Living With Chickens Protect Against Face-Eating Bacteria?

When doctors call a disease "multifactorial in causation" it's a fancy way of obscuring that they don't know what causes it.

When doctors knew nothing and could do even less (if actively harming patients with their treatment counts as doing less than nothing), they hid their ignorance and therapeutic impotence by the use of impressive-sounding Latin terminology. Even when they spoke in the vernacular, they did their best to be incomprehensible, and generally succeeded. Portentousness was then a substitute for prowess.

Doctors are still inclined to use impressive-sounding words for the same purpose: or at any rate, so their critics say. Idiopathic is a learned way of saying that the cause of a disease is unknown; and when a disease is said to be multifactorial in causation, it is an implicit avowal of ignorance: for diseases should at least have necessary causes if doctors can claim to understand them.

Actually, most diseases are multifactorial: necessary conditions of causation in medicine are common, while sufficient conditions are rare. For example, the presence of the tubercle bacillus is a necessary condition for the development of tuberculosis, but not sufficient. Many are the people who are infected who do not get the disease.

An ill-understood condition that is thought nevertheless to be bacterial in origin is noma, or cancrum oris. This is a horrible disease that starts as an infected gum and then eats away a large part of the face, killing the patient or leaving him deformed for life. It now affects mainly children in Africa, but it once occurred in Europe and America and was common in the victims of German concentration camps during the Second World War.

Its cause is unknown, unless extreme poverty and malnutrition can be accepted as causes. Nevertheless, these are an insufficient explanation of the disease because, even in severely impoverished conditions, most people do not get it.

A Swiss group, working in a confined area of Niger, a Sahelian country that was once a French colony and that supplies the uranium from which France generates three quarters of its electricity, tried to find the cause of noma, that is to say a bacterially necessary precondition for its development, by comparing 82 children who suffered from it with over 300 matched control who did not. In summary, they failed to do so as have others before them, though certainly not for lack of trying. Their report of their efforts appears in a recent edition of The Lancet.

In the end they produced a list of factors which were associated with the disease, many of which were already known or suspected. Perhaps the most intriguing such factor — a new one — was the absence of chickens from the homes of children who developed the dread disease.

Could it be that chickens exert a positive protective effect against noma, for example by influencing the bacterial flora of a child’s mouth? After all, one of the explanations of the rise in allergic conditions in western countries is excessive hygiene cleanliness that means that children are not exposed to enough infections to develop a proper immune system which then, faute de mieux, turns on quite harmless substances instead.

The authors do not consider this possibility, but rather take an absence of chickens as being a manifestation of even more extreme poverty than is normal in Niger. They attempted instead to measure the levels of vitamins in the blood of the children, both victims of the disease and controls, but they were low in both groups.

The authors conclude that a higher number of children in the household, recent diarrhoeal or other infectious disease, poor nutrition and altered bacterial flora of the mouth are associated with noma, which remains therefore a mysterious multifactorial disease, as was peptic ulceration before the discovery of the role of the Helicobacter.

Can Living With Chickens Protect Against Face-Eating Bacteria?

So: if I move in with a Republican Congressman or Senator, I will be protected from face-eating bacteria? What about face-saving bacteria? Can we get some for the GOP?

When it comes to bacteria and Africa, water is huge.

I like this idea, maybe the Bill and Melinda Gates Foundation can throw in some billions, or Bono some cash from an "Aid" concert... (although oddly enough, Bono has recently discovered that "capitalism" lifts more people out of poverty than cash to African despots...)

"Portentousness was then a substitute for prowess...Doctors are still inclined to use impressive-sounding words for the same purpose..."

Obscuring the negative, the obvious, words like:

IATROGENIC: induced inadvertently by a physician or surgeon or
by medical treatment or diagnostic procedures


NOSOCOMIAL: hospital acquired infections (e.g., staph)

If you look at the Latin, Iatrogenic means something that generates physicians. If you want a Latin word for something generated by a physician, try iatrogenous.

Nicely written. This is mostly anecdotal but people who live and raise their own food usually are more healthy, live longer and more productive lives even when they do things such as smoke or chew tobacco and drink alcohol.

I suspect it has more to do with nutrition than the researchers want to admit.

Maybe they just need more cholesterol or some other protein found in eggs.
