Dogs + Zoonosis & Human Health

  • Leptospirosis is a bacterial disease of dogs and other mammals that primarily affects the liver or kidneys. The bacteria (Leptospira) that cause leptospirosis, commonly called leptospires, thrive in water. Infected or recovered carrier dogs may act as a source of the infection. There are three main forms of the disease. Antibiotics such as penicillin, ampicillin, and amoxicillin, are reasonably effective against the acute stages of leptospirosis if begun early, although most affected dogs require intensive care in the veterinary hospital.

  • Lyme disease is caused by a spirochete, Borrelia burgdorferi. A spirochete is a type of bacterium. Lyme disease is transmitted to dogs through the bite of a tick. Once in the blood stream, the Lyme disease organism is carried to many parts of the body and is likely to localize in joints.

  • Here are a few facts about Ebola that will provide a reasonable approach to the disease and its risk to pets and their owners.

  • Pruritus is the medical term for itching. It is common in many types of skin disorders. Itching and scratching are commonly associated with flea allergy dermatitis and other allergic skin diseases.

  • Rabies is one of the most devastating viral diseases affecting mammals, including dogs and humans. The danger of a bite from a rabid dog was described in writings dated from the 23rd century BC.

  • 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.

  • 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.

  • Although ticks are commonly thought of as insects, they are actually arachnids similar to scorpions, spiders and mites. All ticks have four pairs of legs (eight legs in total) as adults and have no antennae.

  • Tularemia is an uncommon infection in dogs, but they can be exposed if they kill and/or eat an infected rabbit or rodent.
