Infectious Diseases

  • 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 and can live in many climate zones. Prevention is key to avoid infestations and to prevent disease; preventatives are discussed. Your veterinarian will help you find an appropriate product that works best for you and your pet.

  • Giardiasis is an intestinal infection caused by a microscopic protozoan. The parasites attach themselves to the intestinal wall and the damage causes an acute, sudden onset of foul-smelling diarrhea. Diagnosis may be by routine fecal flotation or presumptively based on clinical signs. Fenbendazole and metronidazole are the drugs most commonly used to kill Giardia. Giardiasis is the most common intestinal parasitic infection of man and can potentially be passed from cats to humans.

  • Heartworms (Dirofilaria immitis) are blood-borne parasites that reside in the heart or nearby large blood vessels of infected animals. Veterinarians now strongly recommend that all cats receive year-round monthly heartworm preventives.

  • There is no drug approved for treating heartworms in cats and surgical removal is generally the best option. Veterinarians now strongly recommend that all cats receive heartworm preventative.

  • Heartworm disease or dirofilariasis is a serious and potentially fatal disease. It is caused by a blood-borne parasite known as Dirofilaria immitis.

  • Heartworm treatment involves several components to combat potential bacterial infection, kill heartworm larvae (microfilaria), kill adult heartworms, and then test to confirm successful treatment. Complete rest for a dog undergoing treatment is essential.

  • Hepatozoonosis in dogs is caused by ingestion of one of two organisms: H. americanum and H. canis. Both parasites are more common in the southern United States. The clinical sign and treatments for dogs with hepatozoonosis differ depending on the parasite species causing the infection. In either case, with appropriate treatment, the prognosis is generally good.

  • Canine herpesvirus, or canine herpes, is a systemic, often fatal disease of puppies caused by the canine herpes virus. It may remain latent in tissues after a dog is infected and may be passed on to other dogs, particularly to fetuses developing in the mother's uterus. Clinical signs in puppies include difficulty breathing, nasal discharge, anorexia, soft stools, crying, seizures, and sudden death. Symptoms in adult dogs include coughing and sneezing, miscarriage, lesions on the external genitalia, conjunctivitis, and corneal ulcers. The disease may be prevented by avoiding contact with infected dogs. Pregnant dogs should be isolated to prevent infection.

  • Feline viral rhinotracheitis (FVR) is an infectious disease caused by feline herpesvirus type-1. It is a major cause of upper respiratory disease in cats and is the most common cause of conjunctivitis. The typical symptoms of FVR involve the nose, throat, and eyes, and include sneezing, nasal congestion, conjunctivitis, excessive blinking, squinting, and discharges from the eyes and nose that range from clear and watery to thick and purulent (containing yellow/green pus). Treatment consists of supportive care, hydration of the environment, and control of secondary bacterial infections with antibiotics and antibiotic eye medications. An effective vaccine exists and is recommended for all cats.
