Infectious Diseases

  • Rabies is a viral disease that can infect all warm-blooded animals, including cats and people, although some species are somewhat naturally resistant to the disease. When signs of rabies occur, it is an almost invariably fatal disease.

  • Rabies is one of the most devastating viral diseases affecting mammals, including dogs and humans. It is a fatal disease caused by infection with the rabies virus. Rabies virus is found throughout the world, including North America, Central and South America, Asia, Africa, the Middle East, and some parts of Europe. Following a bite from a rabid animal, the disease progresses in stages. Dumb rabies is the more common form in dogs. There is progressive paralysis involving the limbs, distortion of the face and a similar difficulty in swallowing. Vaccination is the cornerstone of rabies prevention.

  • Ringworm is the common name given to a fungal infection of the superficial layers of the skin, hair, and nails. The common name of ringworm is somewhat misleading, in that it is not an infection caused by a worm, and the infected areas are not always ring-shaped. Ringworm can be challenging to detect in cats, since the lesions of ringworm may be very mild or even undetectable.

  • Ringworm is the common name given to a fungal infection of the superficial layers of the skin, hair, and nails. The common name of ringworm is somewhat misleading, in that it is not an infection caused by a worm, and the infected areas are not always ring-shaped. In the dog, ringworm lesions usually appear as areas of hair loss (alopecia) that are roughly circular.

  • Rocky Mountain Spotted Fever is spread by various species of ticks and is not confined just to the Rocky Mountain regions of North America. Clinical signs can be non-specific and cover multiple body systems. Early diagnosis and treatment gives the best prognosis for recovery after treatment with antibiotics. Prevention of tick bites and prompt removal of ticks is important.

  • Roundworms are parasites that live freely in the intestine, feeding off of partially digested intestinal contents. Toxocara canis and Toxascaris leonina are two important species of roundworms in dogs. Infected dogs shed the microscopic roundworm eggs in their feces. Other dogs may become infected by sniffing or licking infected feces. There are many safe and effective preparations available to kill adult roundworms in the intestine.

  • Despite sounding like a toxicity, salmon poisoning is actually an infection. Salmon poisoning is caused by a type of bacteria found within parasitic flatworms that infect the tissues of wild fish found in coastal streams of the Pacific Northwest.

  • Swine Influenza or swine flu is a contagious respiratory disease of pigs, caused by a type A influenza virus. Type A influenza viruses can affect a range of other animals and humans. Like all influenza viruses, swine flu viruses change or mutate constantly. Swine flu is commonly seen in North America, South America, Asia, and Europe.

  • Tetanus is a medical condition caused by a toxin. This toxin, produced by the bacteria Clostridium tetani, affects the nerves, spinal cord, and brain, leading to hyperexcitability resulting in muscle spasms. Cats are less susceptible to the effects of tetanus toxin than humans and horses. Tetanus is typically diagnosed based on exam findings. Cats with tetanus require intensive nursing care. Most cats develop localized, self-limiting disease, which will respond to appropriate early treatment.
