A bull in Colorado's Weld County has died from rabies.
The animal tested positive for the disorder, exhibiting many severe clinical signs of rabies. It is the 4th case of rabies positive finds in Colorado this year.
In June, two Weld County horses tested positive, and in April, a Logan County horse tested positive, reports the Colorado Department of Agriculture which monitors such diseases in livestock.
Weld and Logan counties adjoin one another in the southeastern part of the state.
CDA officials are alerting livestock owners and pet households to consider the need for rabies vaccinations with local veterinarians, and monitor animal health for behavioral changes that could indicate onset of rabies.
"Animal owners need to primarily look for any dramatic nervous system changes such as muscle tremors, weakness, lameness, stumbling or paralysis," urges CDA State Veterinarian Keith Roehr. Such signs are hallmark indications that an animal may be suffering from rabies, he adds.
Additional examples of unusual behavior include wild animals that seem to be unafraid of humans, nocturnal critters active during daylight hours, bats on the ground or in pools, or which may have been captured by a pet.
Rabid carnivores, such as skunks, foxes, bobcats, coyotes, dogs and cats, may become aggressive and may attempt to bite people and animals.
Livestock and pet owners are advised to consider vaccination for animals exposed to wildlife that carry and can transmit rabies to dogs, cats, horses, small ruminants, llamas, alpacas and petting zoo animals.
Rabies is a viral disease infecting the brain and nervous system. The clinical appearance of rabies typically falls into two types: aggressive and dumb.
Aggressive rabies symptoms include combativeness and violent behavior and sensitivity to touch. Dumb rabies indications are lethargy, weakness in one or more limbs, and inability to raise the head or make sounds because of throat and neck paralysis.
Rabies can be transmitted to humans from animals.
