DNA is a large complex molecule that carries the genetic information or genetic code of an organism. All common forms of life, such as viruses, bacteria, plants, and animals carry a copy of their own genetic code in each of their cells. Each organism has a unique section of DNA that is just like a fingerprint. DNA-PCR is often used to detect the presence of infectious organisms; especially when detecting extremely small numbers of infectious organisms and for detecting certain viruses and bacteria that are difficult to diagnose by other methods.

Ear canal tumors are abnormal growths that can develop from any part of the ear canal (the skin, the glands of the skin that produce earwax and oil, and the underlying connective tissues, muscles, and bones). Initially, these tumors may appear as one or more pink, white, or purple nodular masses in the ear canal. If benign, they may grow to a certain size and may or may not be problematic. If malignant, they may grow, ulcerate (break open) and bleed, and nearly always become infected, causing recurrent or chronic ear infections. The treatment of choice for ear canal tumors is surgical excision.

The ear mite is a surface mite that lives on cats, dogs, rabbits, and ferrets. It is usually found in the ear canal but it can also live on the skin surface. Mites are barely visible to the naked eye. Clinical signs of infestation vary in severity and may include ear irritation, leading to scratching at the ears or head shaking, dark waxy or crusty discharge from the ear, areas of hair loss resulting from self-trauma, a crusted rash around or in the ear, and an aural hematoma. Your veterinarian will advise you about which insecticidal products are suitable. Your veterinarian may want to re-examine your pet to ensure that the mites have been eliminated after the initial treatment has been performed.

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.

Eclampsia in cats is a rare emergent condition of hypocalcemia that generally occurs one to four weeks after giving birth but can occur before. Risk factors include a poor diet, abnormal parathyroid gland, and calcium supplementation during pregnancy. Signs of eclampsia start as restlessness, panting, and stiffness and can progress to disorientation, tremors, inability to walk, and convulsions. Treatment includes intravenous fluids, careful intravenous calcium supplementation, and other supportive medications followed by oral supplementation and weaning kittens as soon as possible or supplementing their diet with milk replacer.

Endocarditis is an infection of a heart valve, most often affecting the mitral or aortic valve. It can arise any time that bacteria enter the bloodstream, though it is more common when the heart valve has already been damaged for some other reason. The clinical signs of endocarditis are often nonspecific in the early stages, but may progress to include signs of heart failure later in the course of the disease. The diagnosis and treatment of endocarditis can present a challenge, requiring multiple tests and prolonged courses of antibiotic therapy.

Eosinophilic granuloma complex is a term used to describe three forms of skin lesions in cats including eosinophilic plaque, eosinophilic granuloma, and indolent ulcers. The lesions most commonly occur on the lip, sometimes resulting in disfigurement, but can also develop in the mouth or on other areas of the body.

Feline eosinophilic keratitis is a chronic inflammatory disease of the cornea that results in the surface of the eye appearing pink, white, or chalky. It is caused by an accumulation of inflammatory cells called eosinophils. The clinical signs, appearance, diagnosis, and treatment of this condition are explained in this handout.

Esophageal tumors are extremely rare but more often than not malignant type tumors. The cause is unknown but cases in tropical environments may be due to infection by the worm Spirocerca lupi. Treatment options are limited as surgical complications are high due to the advanced nature of the disease at time of diagnosis.

Many liquid potpourri products and essential oils, including oil of cinnamon, citrus, pennyroyal, peppermint, pine, sweet birch, tea tree (melaleuca), wintergreen, and ylang ylang, are poisonous to cats. Both ingestion and skin exposure can be toxic.
