Cow, Goat, Pig & Man Fever

Malcolm Herman Soule, back last week at the University of Michigan, lecturing on bacteriology, has solved the cause of undulant fever's spread in the U. S.

It has long been known that milk from goats infected with Malta fever causes undulant fever in man. More recently it was discovered that milk from cows suffering from contagious abortion causes undulant fever. Bacteriologist Soule found that pigs apparently healthy carried a germ that causes undulant fever. The four germs are very much alike, yet different enough to have fooled bacteriologists. Dr. Soule, by brilliant laboratory technique, proved that the four were the same, looking different and acting, differently in different animal hosts. Cooking-heat kills them.
