Infectious Diseases

  • EVA is a highly contagious disease that can cause a 'flu-like' illness of varying severity and occasionally abortion or even death in horses. It is found in many different parts of the world and is endemic (widespread) in many continental European horse populations.

  • Feather loss occurs either because the bird is truly losing feathers or because the bird, or its cage-mate, is picking out its feathers. Feather-picking is often a behavioral problem, especially in the larger species of birds (such as cockatoos, macaws, and African gray parrots). However, feather loss and feather-picking can also be caused by diseases that result in irritation or pain for the bird, or damage to, or inappropriate growth of feathers. Your veterinarian may have to many perform several diagnostic tests to rule out potential causes. Treatment of feather loss depends on the cause. Feather loss and feather-picking are complicated problems; for specific advice, your bird should have a thorough work-up by a veterinarian familiar with birds.

  • Fechavirus is a chapparvovirus, which is a type of parvovirus. It is a newly discovered gastrointestinal virus identified in cats in 2018. The virus was discovered during an outbreak of vomiting and diarrhea among cats in three animal shelters in British Columbia, Canada. The significance of fechavirus in pet cats is unknown at this point. The most common signs associated with fechavirus are diarrhea and vomiting. If your veterinarian suspects fechavirus, your cat will receive supportive care in order to control clinical signs and prevent dehydration.

  • Feline calicivirus is a virus that is an important cause of upper respiratory infections and oral disease in cats. The typical clinical signs of an upper respiratory infection involve the nose and throat such as sneezing, nasal congestion, conjunctivitis, and discharge from the nose or eyes. Cats with a calicivirus infection often develop ulcers on the tongue, hard palate, gums, lips, or nose. Calicivirus is highly contagious and infected cats can shed the virus in saliva or secretions from the nose or eyes. The standard core vaccines that are given to cats include immunization against calicivirus and will help reduce the severity of disease and shorten the length of the illness if your cat is exposed.

  • Feline hemotrophic mycoplasmosis (FHM) can be a life-threatening condition from a bacteria that acts as a parasite on red blood cells. The anemia experienced by a cat may be mild and may not cause any obvious signs. Many cases of FHM infection in cats go undetected. If many red blood cells are destroyed, symptomatic anemia occurs. The mucous membranes, readily observed in the conjunctival lining of the eyes and the gums, will be pale to white. Diagnosis can be difficult in some cases and while treatment is available, the prognosis is variable. Antibiotics will be prescribed but may not clear the organism completely if the full course of antibiotics is not given.

  • Feline Immunodeficiency Virus (FIV) is a virus specific to the cat family. It was first recognized in the mid 1980's and it has been found in cats worldwide. Although widespread, it is not a common infection in cats. Only 1-5% of cats show evidence of exposure to the virus. In some cats exposure to the virus leads to clinical signs and symptoms that result in deficiency in the immune system.

  • FIP is associated with a viral infection called feline coronavirus. There are many different strains of feline coronavirus, which differ in their ability to cause disease. Feline enteric coronavirus strains can mutate to the more harmful type of virus and cause FIP disease. Many of the clinical signs of FIP are vague and occur with other diseases found in cats. Most cats will develop the wet or effusive form of FIP, which refers to the accumulation of fluid in body cavities; fluid may accumulate in the abdomen. Unfortunately there are no laboratory tests available that can distinguish between the enteric coronavirus and the FIP-causing strains. FIP is fatal in almost all cases. Supportive treatments may extend longevity and improve quality of life, however, there is no specific cure. If your cat has FIP, other cats in your household may be at a greater risk for becoming infected with feline coronavirus.

  • Feline leukemia virus is a virus that infects cats and can cause a variety of diseases in addition to leukemia. It suppresses the immune system and makes cats susceptible to infections and disease, including causing cancers. It is transmitted between cats through the exchange of bodily fluids, although usually an extended period of contact is necessary. It is easy to diagnose, but there is no cure for it. There is a vaccine available that is recommended based on a cat's lifestyle and risk factors.

  • The term panleukopenia means a decrease in the number of all of the white blood cells in the body. Feline panleukopenia virus is present in all excretions, particularly the feces, of infected cats. Cats typically experience depression or listlessness which may progress to collapse. Vomiting and diarrhea are frequent and the diarrhea may contain blood. Dehydration and secondary infections can easily occur. Antibiotics are ineffective against viruses, but are helpful in controlling the secondary bacterial infections that commonly occur. Vaccination is important to protect cats from this destructive virus.

  • Flea and tick prevention consists of a variety of products used to control flea and/or tick infestations on your pet and to prevent infestations inside the home. Fleas and ticks can be found worldwide. Fleas can live in many climate zones, but they prefer humid and shady areas, such as under leaf litter. Ticks can also live in many climate zones, and prefer humid and shady environments, especially areas with woods, shrubs, weeds, and tall grasses. Prevention is key to avoid infestations in your home, severe allergic reactions (in both pets and people), and to prevent disease. Many flea and tick preventives are available. Your veterinarian will help you find an appropriate product that works best for your and your pet.
