Texas Fever -- It’s that urge we expatriates experience in the springtime – Oh, to be back in Texas.
It’s also a disease of cattle, one that nearly wrecked the Texas cattle industry in the 19th-20th centuries.
Irene B. recently mentioned ticks, those little reminders of the dangers of springtime strolls in the woods. Ticks are more than unpleasant; when they bite they can transmit some pretty unpleasant diseases. Illnesses of animals passed along to humans. In the East, we worry mostly about Rocky Mountain Spotted Fever and Lyme disease (widely mis-diagnosed?).
Texas Fever appeared when Longhorns were trailed north and mixed with northern (Yankee?) cattle. The northern herds died. The disease was so costly that a quarantine against Longhorns nearly destroyed the Texas cattle industry. Pioneering research by entomologists revealed that Texas Fever was transmitted by a kind of tick (the first demonstration of a tick-borne disease).
Once the mode of transmission was discovered, the Texas Fever Tick was eradicated by dipping the cattle. Robert J. Kleberg is credited with building the first dipping tanks (Bob G. showed me some old abandoned dipping tanks on his South Texas Rancho). The Texas cattle industry survived.
Ticks can transmit a variety of diseases, from animals to man (humans aren’t natural hosts of ticks). In the 1940’s a tick-transmitted disease struck Camp Bullis north of San Antonio. It was named “Bullis Fever,” transmitted by (how appropriate!) the Lone Star Tick. You’ll recognize that common wood tick by the white star on it’s back. Bullis fever vanished as suddenly as it appeared.
