How is hemotropic mycoplasma transmitted to pets?

Hemotropic mycoplasma is typically spread through blood, and transmission may be linked to biting insects, bite wounds, or shared contaminated equipment. If there is a risk of exposure, consult your veterinarian about preventive measures.

How does a vet test for hemotropic mycoplasma infection?

The veterinarian will use blood tests (complete blood count), blood smear examination, and molecular testing (PCR) to check for parasites or blood abnormalities, and will then plan further management accordingly.

How often do blood values need to be monitored after treatment?

During treatment, several follow-up visits are usually needed to monitor blood count and biochemistry values. The interval between visits may range from a few weeks to several months, depending on the patient's condition and test results as determined by the veterinarian.

How can I reduce the risk of my pet being reinfected?

Maintaining effective flea and tick prevention, avoiding situations involving animal bites or blood-to-blood contact, and screening before transfusions or surgical procedures can reduce the risk of transmission. Consult your vet if you have any concerns.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

Hemotropic Mycoplasma in Dogs & Cats: Symptoms, Diagnosis & Treatment [2025]

Hemotropic mycoplasma is transmitted by ticks and parasitizes red blood cells, causing hemolytic anemia. PCR is the definitive diagnostic method; treatment is primarily antibiotic-based and the prognosis is generally good, though pets may become carriers.

When to See a Vet

Seek Emergency Care Immediately

•Sudden collapse with prolonged unresponsiveness
•Pale gums or dark purple lips with severe weakness
•Dark brown or red urine that persists without improvement

Schedule a Clinic Visit Soon (within 24–72 hours)

•Noticeably reduced activity with prolonged lethargy
•Persistent fever or body temperature elevated above normal for more than one day
•Significantly reduced appetite or refusal to eat for two days with low energy

01What symptoms indicate something is wrong?

Hemotropic mycoplasma infection commonly affects energy levels and blood function. Clinical signs are typically related to fatigue, fever, and jaundice, and must be confirmed by a veterinarian through laboratory testing.

Noticeably reduced activity or persistent lethargy
Decreased appetite or changes in the amount or frequency of eating
Recurring fever or abnormally elevated body temperature
Jaundice (yellowing of the skin or whites of the eyes)
Depressed demeanour, reduced interaction, or sluggish responses

Seek emergency care immediately if you notice the following symptoms:

⚠️ Sudden collapse with prolonged unresponsiveness
⚠️ Pale gums or dark-purple lips accompanied by weakness

02How should you assess the situation at home? Key things to observe and when to go to emergency

Tracking changes at home helps your veterinarian quickly understand the course of illness. Record frequency, timing, and any video or photo evidence as accurately as possible to assist with diagnosis.

Record daily food intake, meal frequency, and any episodes of refusal to eat
If you can measure body temperature, note the time and any changes in readings
Observe and document activity level, lethargy, and degree of interaction
Note changes in stool colour, bowel frequency, and urine output
Use your phone to record videos or photos of symptoms for the veterinarian's reference

03How will the vet make a diagnosis? Common tests and procedures

Upon arrival at the clinic, the veterinarian will perform a physical examination and blood tests to confirm whether there is blood parasitism or hemolytic changes and to assess severity.

Full physical examination

palpation, assessment of mucous membrane colour, and body temperature

Complete blood count (CBC)

evaluation of anaemia and white blood cell changes

Biochemistry panel

assessment of liver and kidney function and electrolyte status

Blood smear or microscopic examination

looking for parasites or abnormal cells

PCR molecular testing

confirming the presence of hemotropic mycoplasma

04What treatment and aftercare are needed? Medications, dietary adjustments, and care guide

Treatment focuses on controlling the infection and providing supportive care. Regular monitoring of blood values and clinical signs is needed to confirm the effectiveness of therapy and recovery progress.

The vet will arrange targeted treatment and supportive care based on test results
Ensure adequate hydration and rest, and adjust diet as needed
Schedule follow-up visits to monitor blood count and biochemistry values
Continue observing for improvement in jaundice, body temperature, and overall demeanour
If the condition is unstable or keeps recurring, consider referral to a specialist hospital for further care

05What should you prepare before the vet visit? Key information to help your vet identify the cause quickly

Record the onset date, when symptoms first appeared, and how they have progressed

Bring a log of food intake, bowel habits, and body temperature readings

Bring a list of all current medications and supplements

Prepare symptom videos or photos for the veterinarian's reference

Bring any prior test reports or medical records from other clinics if available

It is advisable to call ahead and book an appointment with a clinic experienced in infectious or internal medicine
