Sarcoptic mange, also known as scabies, is caused by a parasitic mite that burrows just beneath the surface of the skin. The presence of the sarcoptic mite causes intense itching; an affected dog will constantly chew and scratch his skin. Sarcoptic mange is highly contagious to other dogs and humans.

Selamectin + sarolaner is used topically on the skin to treat various parasites, both on and off-label, and prevent heartworm in cats. Side effects are rare but may include hair loss at the application site, gastrointestinal upset, skin reactions, or neurologic signs. It should be used with caution in sick or underweight cats. If a negative reaction occurs, please call your veterinary office.

Strangles is an infection caused by bacteria called Streptococcus equi. It is highly contagious and the infection can be spread by horse-to-horse contact or by humans, tack, drinking troughs and other environmental factors.

H1N1 influenza virus emerged in pigs as a genetic sharing of DNA from both human and swine influenza viruses. It caused a deadly pandemic in 2009 and continues to be an important cause of illness today. Pets including cats and dogs can be infected from their owners and become ill. It is not yet known to transfer from pets to humans. Good hygiene and restricted exposure should be taken immediately if there is any sign of influenza-like infection to restrict spread between humans, and between humans and their pets or domestic animals.

Tapeworms are parasites that infect the gastrointestinal tract of cats, other animals, and humans. Several types of tapeworms are known to infect pets, but the most common species observed in cats is Dipylidium caninum, which is transmitted through fleas. Risk factors, clinical signs, treatment, and prevention are explained in this handout. Other, less common types of tapeworms that affect cats and humans are also covered.

There are several tests for diagnosing leptospirosis, but the two most common ones are the DNA-PCR test and the microscopic agglutination test (MAT). Infection can be diagnosed with either test, but each has limitations, and in some situations, both tests may be needed to reach a diagnosis.

Tetanus is a medical condition caused by a toxin. This toxin, produced by the bacteria Clostridium tetani, affects the nerves, spinal cord, and brain, leading to hyperexcitability resulting in muscle spasms. Cats are less susceptible to the effects of tetanus toxin than humans and horses. Tetanus is typically diagnosed based on exam findings. Cats with tetanus require intensive nursing care. Most cats develop localized, self-limiting disease, which will respond to appropriate early treatment.

Toxoplasma occurs worldwide. However, infection is uncommon in pet cats that do little or no hunting and primarily or exclusively eat commercial cat foods. Despite the high number of cats infected with T. gondii, very few show significant clinical signs. Humans are most commonly infected by eating contaminated food. Most people infected with this organism do not develop clinical disease. However, infection during pregnancy may be transmitted to the fetus and sometimes cause severe damage. Many pet cats will never be exposed to Toxoplasma and, therefore, cannot pass the infection on to humans.
