  • Heartworm Disease in Dogs

    La enfermedad de los gusanos del corazón o dirofilariosis es una enfermedad grave y potencialmente fatal. Está causada por un parásito sanguíneo llamado Dirofilaria immitis.

  • Lyme Disease in Dogs

    La enfermedad de Lyme está causada por una espiroqueta, Borrelia burgdorferi. Una espiroqueta es un tipo de bacteria. La enfermedad de Lyme se transmite a los perros a través de la picadura de una garrapata. Una vez en el torrente sanguíneo, el organismo de la enfermedad de Lyme será transportado a diferentes partes del cuerpo y puede llegar a las articulaciones. Antes se pensaba que sólo un tipo concreto de garrapatas podían transmitir la enfermedad, pero ahora parece ser que muchos tipos de especies están implicadas. El tipo más común de garrapata portadora de la enfermedad de Lyme es la garrapata ciervo.

  • Famciclovir is given by mouth and is used off-label to control feline herpesvirus. Give as directed. Side effects may include vomiting, diarrhea, decreased appetite, and increased drinking and urination. Do not use it in pets that are allergic to it or penciclovir. If a negative reaction occurs, call your veterinary office.

  • 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.

  • This handout provides information on Feline Immunodeficiency Virus (FIV) in cats. Included is information on how the disease is transmitted, the clinical signs, the recommendations for isolation of the infected cats, and potential treatment guidelines should your cat be infected with this virus.

  • 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.

  • Feline leukemia virus (FeLV) is a virus that infects only cats. It depresses the immune system and cats tend to remain infected for life. FeLV vaccines have been available for many years and have been continuously improved upon. They are helpful in preventing infection with FeLV and, therefore, in controlling FeLV-related disease. Your veterinarian can discuss the pros and cons of vaccinating your cat against this disease based on her specific lifestyle and risk of exposure.
