  • Leishmaniasis is a disease caused by a protozoan parasite transmitted by sandflies and is most commonly seen in the Mediterranean, Middle East, and South and Central America. It has been reported in some parts of the United States. Clinical signs include hard skin nodules, weakness, decreased appetite, vomiting, diarrhea, and more. Diagnosis is based on travel history, clinical signs, and diagnostic testing. The goal of treatment is to resolve clinical signs. Prognosis is guarded to grave depending on the severity of the disease.

  • Leptospirosis is a bacterial disease of dogs and other mammals that primarily affects the liver or kidneys. The bacteria (Leptospira) that cause leptospirosis thrive in water. Infected or recovered carrier dogs may act as a source of the infection. Antibiotics such as penicillin, ampicillin, and amoxicillin are reasonably effective against the acute stages of leptospirosis, if started early, although most affected dogs require intensive care in the veterinary hospital. This disease can be transmitted to humans.

  • The bacterium that causes Lyme disease can be transmitted to dogs through the bite of an infected tick, most commonly the deer tick (black-legged tick), which is found in the midwestern and eastern United States and throughout Canada.

  • Melioidosis is a bacterial infection that is typically associated with tropical regions. The bacteria that causes melioidosis, Burkholderia pseudomallei, is usually found in soil and water. The clinical signs of this condition, along with transmission, diagnosis, treatment, and prognosis, are outlined in this handout.

  • The Ebola virus is very contagious and is transmitted through blood, body fluids, and tissues, but not through air, water, or food. Ebola affects humans, non-human primates, and is carried by fruit bats. Other species do not appear to be affected, although there has been evidence of exposure to the disease in dogs, cats, and other domestic animals. Domestic animals are not believed to transmit the virus; however, there is a risk that they could transmit body fluids such as saliva on their fur to other humans. Any potential exposure to Ebola should be reported to your veterinarian who will contact the Center for Disease Control (CDC).

  • Feline poxvirus is a relative of the human smallpox virus seen mainly in Asia, Europe, and England. It causes skin lesions around the head, neck, and forelimbs, such as ulcerations, scabs, or abscesses. Cats often recover on their own with no further symptoms unless they are immunocompromised. There is no specific treatment or vaccine. Antibiotics may be used to control secondary infections. The virus can be transmitted to humans but can be significantly reduced by basic hygiene precautions.

  • 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. Vaccination and post-exposure quarantine are discussed.

  • 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. Following a bite from a rabid animal, the disease progresses in stages. Vaccination is the cornerstone of rabies prevention.

  • Feeding raw food to cats is potentially dangerous - not only to the cat eating the raw food, but also to other pets and humans in the environment, due to the high likelihood of bacterial contamination. Raw food may also not be complete and balanced and could lead to nutrient deficiencies or toxicities. Consuming raw food with bones can lead to life-threatening foreign body obstruction.

  • Ringworm infections in cats are caused by a fungus, not a worm. They can be easily recognized, though definitive testing by fungal culture is recommended. Ringworm is highly contagious and can be spread between animals and from animals to people. The clinical signs, diagnosis, treatment, and risks are explained in this handout.
