Echinococcosis refers to being infected with a tapeworm of the genus Echinococcus and is primarily a parasite of coyotes and foxes. Infected cats are usually asymptomatic, but in both cats and humans the parasite can cause large cysts to form within the lungs and liver. E.multilocularis is treated with praziquantel and in most cases the prognosis is good.

Ehrlichiosis is a tick-borne bacterial (Ehrlichia) infection spread by the brown dog tick found in many areas of North America. There appear to be three stages of disease: acute, sub-clinical, and chronic or clinical. Abnormal findings on initial lab work include thrombocytopenia, anemia, hyperglobulinemia, and proteinuria. In-clinic ELISA tests can be used to screen for exposure but will be negative if the infection is new. Blood can be sent for PCR testing to demonstrate infection and to determine the species of Ehrlichia. Prevention includes minimizing exposure to ticks and use of tick prevention medication regularly.

Encephalitozoonsis is a parasitic infection that can affect the kidneys, eyes, and nervous systems of rabbits. Many infected rabbits do not develop clinical signs until they are older or if they become stressed or immunocompromised. Common signs that may develop include heavy white plaques/growths inside one or both eyes, head tilt, eye twitching, and tremors or seizures. Treatments are available, though not all rabbits respond.

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.

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 Destructive Behavior (FDB) is a general classification that describes the many types of damage a bird can do to its own feathers, including feather picking. 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. 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 type of parvovirus. It is a newly discovered gastrointestinal virus identified in cats in 2018. 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 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. 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) is caused by a microscopic bacterial parasite that attaches itself to the surface of the cat's red blood cells. The infected blood cells may break down, or they may be treated as “foreign” by the cat's immune system and be destroyed. Anemia occurs if enough red blood cells are infected and destroyed. The test of choice is called a PCR assay. Broad-spectrum antibiotics such as doxycycline, enrofloxacin, or marbofloxacin are used to treat M.Haemofelis infections. Transmission is not fully understood.

Feline herpes viral conjunctivitis is a form of primary conjunctivitis caused by the highly infectious feline herpesvirus (FHV-1), which is the most common cause of conjunctivitis in cats. This handout outlines the clinical signs, diagnosis, treatment, and prognosis for affected cats.

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.
