Absolutely. Cattle and horse born diseases spread all along the trail. Of course with any travel some human illnesses would travel too. Look at how smallpox spread to the Indians as explorers and traders moved west. Cattle would also carry seeds for noxious (unwanted/hard to kill) weeds and vermin. For many years cattle coming from Mexico had to be dipped in pesticides to kill the lice and tics before they could be brought to the US.
Spread disease
Cattle Ranching started in Texas and spread all throughout the West.
It is believed that grasshoppers do spread disease. In the past, it has been proven that grasshoppers spread the VSV virus to cattle and horses.
A nasty disease called the Texas Fever.

Cattle trails were commonly found in the 19th century in the western United States, particularly in states like Texas, Kansas, and Nebraska. These trails were used to drive cattle from ranches to railheads for transportation to markets. Many of these historic cattle trails have since been incorporated into modern roads and highways.
If by trails you mean cattle drives, the purpose was to move large herds of cattle to the nearest railroad stop so the cattle could be shipped to other parts of the country, usually larger cities in the east.
The three great cattle trails include the western trail, the Chisholm trail and the goodnight loving trail.
Chisolm Trail is one.
