Mycoplasma infections in cats are caused by small, cell-wall–deficient bacteria of the genus Mycoplasma. The most common species affecting cats are Mycoplasma haemofelis, Candidatus Mycoplasma haemominutum, and Candidatus Mycoplasma turicensis. These bacteria primarily infect red blood cells, leading to feline hemoplasmosis, a condition characterized by anemia and systemic illness. Kittens, elderly cats, and immunocompromised felines are especially susceptible, making early detection and treatment critical.

How Mycoplasma Spreads

Mycoplasma infections in cats are commonly transmitted through blood-sucking parasites like fleas or ticks. Other routes include fighting with infected cats, blood transfusions, or vertical transmission from mother to kittens. Immunocompromised cats, such as those with FIV or FeLV, are at higher risk of severe disease.

Key ways Mycoplasma spreads:

• Flea or tick bites introducing the bacteria into the bloodstream
• Blood transfusions from infected or unscreened donors
• Bites and scratches during fights with infected cats
• Vertical transmission from mother to kittens

Implementing flea control, limiting exposure to unknown cats, and careful handling are essential to prevent infection.

Symptoms of Mycoplasma Infection

The clinical signs of feline hemoplasmosis vary depending on infection severity. Some cats may be asymptomatic carriers, while others develop significant anemia and systemic illness.

Common signs of Mycoplasma infections in cats:

• Pale or yellow gums and mucous membranes due to anemia
• Lethargy and weakness
• Loss of appetite and weight loss
• Fever and general malaise
• Rapid breathing and reduced activity in severe cases

Early recognition of these symptoms is important for prompt veterinary intervention and better outcomes.

Diagnosis and Treatment

Diagnosis involves blood tests, PCR, and blood smears to detect the bacteria. Veterinarians also perform a complete blood count (CBC) to assess anemia.

Treatment of feline hemoplasmosis typically includes antibiotics such as doxycycline or enrofloxacin, supportive care with fluids and nutritional support, and in severe cases, blood transfusions. Timely treatment improves recovery, although some cats may remain asymptomatic carriers.

Prevention

Preventing Mycoplasma infections in cats focuses on reducing exposure and maintaining overall feline health. Regular flea and tick control, avoiding fights with unknown cats, using screened blood donors, and routine veterinary check-ups are crucial preventive strategies. Proper hygiene, prompt care for wounds, and vaccination programs where applicable can reduce the risk of feline hemoplasmosis outbreaks.

FAQs

1. What is feline hemoplasmosis?

Feline hemoplasmosis is a disease caused by Mycoplasma bacteria infecting red blood cells, leading to anemia, weakness, and lethargy in cats.

2. How do cats get Mycoplasma infections?

Cats can acquire Mycoplasma bacteria through flea or tick bites, blood transfusions from unscreened donors, fighting with infected cats, or vertical transmission from mother to kittens.

3. What are the symptoms of Mycoplasma infections in cats?

Symptoms include pale or yellow gums, lethargy, loss of appetite, fever, weight loss, rapid breathing, and reduced activity.

4. Can feline hemoplasmosis be treated?

Yes. Treatment involves antibiotics, supportive care, and in severe cases, blood transfusions. Early diagnosis improves recovery and reduces complications.

5. How can I prevent Mycoplasma infections in cats?

Prevention relies on flea and tick control, avoiding fights with unknown cats, using screened blood donors, and maintaining regular veterinary care.
