Cattle & Bison Health
Brucellosis is a contagious disease of cattle, bison, swine, and other ruminant animals that can also affect humans. The disease in cattle is also known as contagious abortion or "Bang’s disease". In humans, it's known as undulant fever because of the intermittent fever it causes.
In animals, brucellosis can cause decreased milk production, weight loss, loss of young, infertility, and lameness. The disease in cattle is caused by the bacterium Brucella abortus, though other species of Brucella bacteria can cause disease in a variety of other species.
Brucellosis is a zoonotic disease, meaning it can be spread from animals to people, but eradication efforts along with modern sanitary practices and pasteurization of milk products have greatly decreased the frequency of human infections.
Cattle Fever Ticks, known scientifically as Rhipicephalus (formerly Boophilus) annulatus and R. microplus, are a significant threat to the United States cattle industry.
These ticks are capable of carrying the protozoa, or microscopic parasits, Babesia bovis or B. bigemina, commonly known as cattle fever. The Babesia organism attacks and destroys red blood cells, causing acute anemia, high fever, and enlargement of the spleen and liver, ultimately resulting in death for up to 90 percent of susceptible naive cattle.
Cattle Fever Tick Quarantine Areas
- Cameron County Temporary Preventative Quarantine Area (TPQA)
- The Texas Animal Health Commission and the United States Department of Agriculture confirmed the presence of cattle fever ticks on Cameron County premises located outside the permanent quarantine zone in 2014.
- In order to protect the land, premises, and animals from exposure to cattle fever ticks, the TAHC created a temporary preventative quarantine area (TPQA) in Cameron County. The TPQA, and its requirements, became effective October 7, 2014. The TPQA was modified on November 17, 2016 and now consists of approximately 200,000 acres. The TPQA will be in effect until all premises within it are released from fever tick quarantines and the area is determined to no longer be at risk of infestation.
- Within this area, all livestock (cattle and equine) and live or hunted wildlife (such as nilgai antelope and white-tailed deer) that are capable of hosting fever ticks, are subject to movement restrictions, inspections and treatment as prescribed by TAHC fever tick regulations.

Their are three types of Fever Tick Quarantine Areas; The Permanent Fever Tick Quarantine "Buffer" Zone, a Control Purpose Quarantine Area, and a Temporary Preventative Quarantine Area. To learn more about the statewide fever tick response, please visit the TAHC Monthly Fever Tick Situation Report.

TAHC Seeking Input Regarding Female Cattle and Trichomoniasis, learn more by clicking here.
Cattle trichomoniasis or "Trich" is a venereal disease of cattle caused by the Tritrichomonas foetus protozoa, which is about the size of a sperm. Infected bulls carry the organism on their penis and prepuce. Trichomoniasis is then transmitted to cows through breeding. Cows may abort early in the pregnancy and become temporarily infertile. Only testing will confirm the presence or absence of the disease.
Cattle producers can lose valuable income from the extended breeding seasons and diminished calf crops caused by this disease. The cattle industry and trade associations in Texas requested that the Texas Animal Health Commission develop regulations to stop the introduction and spread of this disease.
TAHC’s Trichomoniasis regulations were developed with a working group of producers, market operators, veterinarians, laboratory representatives and educators. Under the program that was phased in beginning April 2009, Trichomoniasis is a reportable disease in Texas. The program will be reviewed annually by the Trichomoniasis Review Working Group.For Producers: Find a Trichomoniasis Certified Veterinarian

Tuberculosis (TB) is a chronic, debilitating disease of cattle and bison caused by the bacterium Mycobacterium bovis. Human tuberculosis is caused by a closely related type of bacteria and was historically known as "consumption". A variety of other species may be susceptible to cattle tuberculosis, including captive elk and exotic deer, bison, goats, swine, man and cats. Sheep and horses are rarely affected.
TB is primarily a respiratory disease affecting lungs and chest lymph nodes. Symptoms can include progressive weight loss, chronic cough, and unexplained death losses.
TB has a long incubation period (months to years) and was once the most prevalent infectious disease of cattle and swine in the United States. Bovine TB caused more losses among U.S. farm animals in the early part of this century than all other infectious diseases combined. Through a cooperative state-federal program, bovine tuberculosis has been nearly eradicated from livestock in the US. Texas has been declared free of TB, but constant vigilance is crucial to maintaining that TB-free status.
