Infectious Diseases

  • Brucellosis is a contagious bacterial infection that can cause a number of reproductive problems, including infertility and abortion in breeding dogs. Male dogs infected with brucellosis develop epididymitis, an infection of the testicle. Female dogs infected with brucellosis develop an infection of the uterus. The infection is usually diagnosed by a blood test (rapid slide agglutination test). Treatment with antibiotics is not significantly effective and infected dogs should be removed from the breeding population. In the United States, brucellosis is a reportable disease.

  • Campylobacter infection or Campylobacterosis is a bacterial intestinal infection cased by Campylobacter jejuni and Campylobacter upsaliensis. It is a major cause of human bacterial enteritis although it is considered a normal bacterium in the intestinal tract of many animals and birds.

  • Canine coronavirus (CCoV) is not the same virus as SARS-CoV-2 that 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. Dogs may be carriers of the disease for up to six months (180 days) after infection. The most typical sign associated with canine coronavirus is diarrhea, typically sudden in onset, which may be accompanied by lethargy and decreased appetite. There is no specific treatment for coronavirus. Canine coronavirus vaccines are available. This vaccine will only work for the CCoV type of coronavirus.

  • Capillaria is a small internal parasite, related to intestinal worms. Capillaria, however, can live in a number of areas within the body, including the bladder and respiratory tract. There are multiple species of Capillaria; some species affect cats, some affect dogs, and some can affect both species. These parasites are acquired from the environment, when a cat eats the Capillaria eggs directly or eats an earthworm infected with the parasite. Treatment is simple and effective, though diagnosis can be challenging.

  • 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 an infrequent occurrence. If you contract COVID-19, you will need to remain quarantined on your property which may make caring for dogs a bit more challenging. If you suspect that you may have COVID-19 (with or without a positive test result), you should minimize contact with your pets. Just as you would quarantine yourself from the other human members of your home while sick, you should also quarantine yourself from your pets. If you are hospitalized and your pets must be cared for by a boarding kennel or pet sitter, inform the kennel or pet sitter that you are ill, allowing them to take the necessary precautions.

  • Cat bites are puncture wounds that can cause bacterial infections with Pasteurella multocida that can spread within the tissues or into the blood stream. Any bite should be cleaned immediately and assessed by a physician as soon as possible, as antibiotics are frequently needed to treat infection. Your doctor may recommend vaccination with tetanus or rabies prophylaxis. Your doctor will report any bite to the local health department and your cat will have to undergo a quarantine – the length of which depends on their rabies vaccination status.

  • 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 contaminating skin lesions or their eyes. Signs include fever, lethargy, enlarged lymph nodes, and lesions on the conjunctiva 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. Strict flea control, good hygiene, keeping your cat indoors, and keeping your cat’s nails trimmed are among the most important ways to try to prevent CSD.

  • Chagas disease, also known as American Trypanosomiasis, is an infection that is primarily observed in Latin America. In recent years, however, this infection has been observed at various sites in the Southern United States. Chagas disease is spread by the bite of certain insects, including the Mexican Kissing Beetle and other related insects. The clinical signs of Chagas disease are variable and non-specific. There is currently no consensus on the best method of treatment for Chagas disease.

  • Cheyletiellosis is an uncommon but highly contagious skin parasite of dogs, cats and rabbits caused by Cheyletiella spp. mites. It is also referred to as walking dandruff due to the appearance of the large, whitish mites as they crawl across skin and fur, and the excessive scaling that accompanies the infection.
