Tetanus is typically caused by C. tetani bacteria entering a wound. Spores of C. tetani are widespread in the environment; these spores are shed in animal feces and can survive for years in dirt and dust.
Tetanus is caused by tetanus toxin (TeNT) produced by Clostridium tetani, an environmental soilborne, gram-positive, sporulating bacterium. The disease most often results from wound contamination by soil containing C. tetani spores.
Tetanus is a medical condition caused by a toxin. This toxin, produced by the bacteria Clostridium tetaniClostridium tetaniClostridium tetani is a common soil bacterium and the causative agent of tetanus. Vegetative cells of C. tetani are usually rod-shaped and up to 2.5 μm long, but they become enlarged and tennis racket- or drumstick-shaped when forming spores., affects the nerves, spinal cord, and brain, leading to hyperexcitability that results in muscle spasms. Although tetanus can be seen in dogs and cats, it is uncommon in both species.
0 or 1 – Mild tetanus; mortality below 10% 2 or 3 – Moderate tetanus; mortality of 10-20% 4 – Severe tetanus; mortality of 20-40% 5 or 6 – Very severe tetanus; mortality above 50%
Symptoms of generalized tetanus in dogs include:
Symptoms of Tetanus in Dogs
Tetanus is commonly known as lockjaw. Severe complications of tetanus can be life-threatening. There's no cure for tetanus. Treatment focuses on managing symptoms and complications until the effects of the tetanus toxin resolve.
The prognosis depends upon the severity of the disease. Most dogs develop localized, self-limiting disease, which will respond to appropriate early treatment. Improvement is often seen within one week of treatment, though it may take 3-4 weeks for patients to fully resolve.
Tetanus is a potentially life-threatening infection that dogs can contract through open wounds. This soil-borne bacterial disease causes muscle stiffness and ultimately death if left untreated, so it is important for dog owners to be aware of the causes, treatments, and prevention of tetanus.
Tetanus symptoms include:
Tetanus often begins with mild spasms in the jaw muscles (lockjaw). The spasms can also affect your chest, neck, back, and abdominal muscles. Back muscle spasms often cause arching, called opisthotonos.
What Causes Tetanus in Dogs? Tetanus is caused by the Clostridium tetani bacteria. This bacteria is commonly found in dirt and dust, as well as fecal matter.
Susan Rehm, medical director of the National Foundation for Infectious Diseases. Almost half of injuries that resulted in tetanus infection between 1998 and 2000 occurred indoors or at home, according to the U.S. Centers for Disease Control and Prevention.
Tetanus does not spread from person to person. The spores of tetanus bacteria live in soil, dust, and manure. The spores can get into the body through broken skin, usually through injuries from contaminated objects.
