What is Mycoplasma Infection?

Mycoplasma infection is caused by a type of bacteria that acts as a parasite in the blood, causing anemia and other signs of infection. Antibiotic treatment may be needed to overcome the disease, especially in cats with poor immune performance.

Mycoplasma infection is a medical condition that affects cats, dogs, farm animals, and people. The bacteria are present in most environments and are often commensals. Most healthy animals will experience little to no symptoms, but the very young or old or those with immune disorders may have severe anemia and other signs of infection. Mycoplasma commonly causes respiratory symptoms like bronchitis and pneumonia, but can cause infection in other parts of the body as well.

Symptoms of Mycoplasma Infection in Cats

The symptoms of Mycoplasma infection can vary based on several factors. The most common symptom is anemia. Clinical signs can vary depending on the severity of the infection, the species of Mycobplasma involved and the immune status of the cat. Symptoms are considerably more severe in animals who have immune disorders and weakened immune systems. The location of the infection also affects the type of symptoms the cat will have. Infections can be located in the respiratory system, urinary tract, joints, or reproductive system. 

Common symptoms include:

Symptoms related to the infection location include:

Causes of Mycoplasma Infection in Cats

Mycoplasma infection is caused by exposure to the bacteria. This can occur in almost any setting, as this type of bacteria is very common. It can spread easily between animals, making it common in shelters and kennels as well as multi-pet homes. The infection is not limited to cats, and can be caught from or given to other companion animals. Humans are also at risk of infection. Immunodeficiency and conditions that weaken or suppress the immune system increase the risk of contracting the disease.

Diagnosis of Mycoplasma Infection in Cats

A veterinarian can diagnose Mycoplasma infection using various medical testing procedures to visually confirm the organisms in blood, urine, or other fluids. PCR tests are frequently used. Before proceeding to this step, a physical examination and medical history of the cat are required. Be prepared to discuss the symptoms and timeframes associated with your pet’s illness. If clinical signs point to a bacterial infection, your veterinarian will collect fluids for testing purposes. The fluid collected will depend on the type and location of the symptoms your cat is exhibiting. For example, a urinalysis or urine testing are effective in situations where the animal is experience related symptoms. Joint fluid, mucus, and blood samples can also be analyzed. Dye staining has been shown to be an effective method for locating the bacteria that cause the infection in cats.

Treatment of Mycoplasma Infection in Cats

No single treatment or protocol is considered consistently effective in treating Mycoplasma infection. Treatments will vary depending on the severity of symptoms and location of the infection within the body. Antibiotics are the most common form of treatment, but the type of antimicrobial the bacteria is susceptible to is not the same in all cases. To completely overcome the disease, treatments may continue for an extended period of time. Although treatment plans may differ, most cats will not require hospitalization unless their symptoms are very severe or in animals with poor immune function. Recommended treatments may include:

Antibiotics:  Most cats will require a minimum seven to ten-day course of antibiotics to treat the primary infection. Because Mycoplasma infections can be hard to eradicate, more than one course of antibiotics may be necessary for a full recovery. 

Analgesics:  If pain, inflammation, or fever is severe, painkillers may be prescribed. Be sure to carefully follow your veterinarian’s instructions if you will be dosing your pet with painkillers at home. Too much of this type of medication can be very dangerous to your cat. 

Supportive care: Ensuring your cat is eating well, is well hydrated and well rested will go a long way towards healing their recovery.

Recovery of Mycoplasma Infection in Cats

Most cats with normal immune function are expected to make a full recovery from the disease, although it may take several weeks to completely rid your pet of the infection. Once antibiotic treatment has begun, symptom improvement can be expected within a few days. Anemia symptoms may take longer to recover from. Carefully monitor your pet’s food and water intake while they are recovering to make sure your cat is receiving the proper nutrition to recover.

Reinfection is a risk with Mycoplasma, so pet areas should be thoroughly cleaned and disinfected. Continued disinfection should be maintained until your pet has completed their antibiotic treatment. If there are multiple animals in the home, isolation may be necessary to prevent the spread of infection. Take your pet back to the veterinarian if symptoms get worse, don’t improve after a week’s time, or come back.

Hi, i have a cat who has been diagnosed with mycoplasma. She is taking treatment and the 5 other cats in the household have been tested but turned out to be negative. Due to the incubation period should the 5 other cats be retested after 30 days?

Mycoplasma is a very common organism in the environment, and it typically does take an underlying problem to have it cause disease. If the other cats seem healthy and are doing well, you may be fine to monitor them for any clinical signs since they have tested negative. Since I do not know the full history or situation for Coca, however, it would be best to check with your veterinarian, as there may be complications that I'm not aware of.

My pet has the following symptoms:
Mouth Lump
Stomatitis With Infection
I have a Maine Coon female 3 years old, carrying eosinophilic granuloma. Recently she contracted Mycoplasma felis and she is now treated with Clindamicina 0.7 ml for day and cortison. Then we try a teeth extraction surgery for decrease any possible inflammation trigger. I have other 2 cats, a young male and a female 2 years old. They should be breeding cats so I performed a respiratory tract microbiological test on eye and nose mucous fluids that resulted positive for M felis for both. The 2 cats have no symptoms. What to do? Thanks for attention. Patrizia Iansa Read more at: https://wagwalking.com/cat/condition/mycoplasma-infection

Mycoplasma infections with M. felis may be seen in asymptomatic cats and the decision whether to treat these cases would be down to your Veterinarian; however if you are breeding cats it may be worth treating regardless but you should discuss this with your Veterinarian.
