Infectious Diseases

  • Campylobacteriosis is a bacterial intestinal infection usually acquired by exposure to raw meat, poultry, or infected water, but can be spread between pets and humans. Signs of infection are watery or mucoid diarrhea with straining, possible cramping, lethargy, and fever. Testing, treatment and prevention are discussed.

  • Candida is a type of yeast that may cause problems in the digestive tract of birds. In young birds, immunocompromised birds, or birds that have been on antibiotics for an extended period, candida may overgrow in the digestive tract and cause various problems, such as 'sour crop'.

  • Canine coronavirus (CCoV) is not the same virus as SARS-CoV-2, which causes COVID-19. Canine coronavirus disease, known as CCoV, is a highly infectious intestinal infection in dogs, especially puppies. CCoV does not affect people, and causes gastrointestinal problems as opposed to respiratory disease. Crowding and unsanitary conditions lead to coronavirus transmission. This article discusses signs, treatment, and vaccines for this disease.

  • Kennel cough is the common name for an infectious respiratory disease that affects the trachea and lower airways in dogs. Viral or bacterial pathogens may cause it. Treatment may or may not be necessary with antibiotics and, in some cases, anti-inflammatory medication. There are no long-term effects from this infection.

  • Canine influenza is a relatively new, highly contagious virus that causes respiratory disease in dogs. It has been reported in all US states and some Canadian provinces. Clinical signs include coughing, runny nose, and fever. Definitive testing can be performed in the early stages of the disease. Vaccination is recommended for dogs at a higher risk of infection or morbidity. The virus is not spread to humans, but cats can become infected.

  • Capillaria is a small internal parasite, often less than half of a centimeter in length. They are closely related to intestinal worms, though they can live in a variety of locations within the body. Capillaria can affect both dogs and cats, although dogs are more frequently affected. Diagnosis can be difficult because the eggs of Capillaria are shed only on an intermittent basis. While the parasite is easily eliminated with a dewormer, your cat may require additional medications to decrease the inflammation associated with the infection.

  • COVID-19 is a viral respiratory disease of humans that was first discovered in late 2019. The illness is caused by the virus SARS-CoV-2, which is a new coronavirus that has not previously been identified in humans. Certain animals can be infected by the COVID-19 virus, but it appears to be infrequent. Dogs and cats seldom show severe clinical illness if infected with COVID-19.

  • Cat bites can be dangerous both to other animals and to humans. All cats carry bacteria in their mouths that can cause tissue infections in bite wounds. These bites may lead to serious conditions such as cellulitis and/or septicemia. Immediately wash your wound and contact a physician as soon as possible to have the wound properly treated.

  • Cat scratch disease (CSD) is caused by the bacteria Bartonella that is transmitted by cat fleas and other biting insects. Cats act as reservoirs for the bacteria. Humans are exposed to the bacteria through flea feces that contaminate skin lesions or eyes. Signs include fever, lethargy, enlarged lymph nodes, and lesions on the eye and skin. The disease is usually self-limiting; however, some people will require antibiotics, especially if they are immunocompromised. Tests are available for diagnosis in humans as well as in cats. The most important ways you can prevent CSD include strict flea control, good hygiene, keeping your cat indoors, and keeping your cat's nails trimmed.
