Piroplasmosis and piro-like diseases of the horse - Symptoms, Treatments and Prevention

Introduction

Piroplasmosis, or equine babesiosis, is a serious parasitic disease caused by two main types of protozoa: Babesia caballi and Theileria equi. These parasites are transmitted to horses by ticks, notably of the Dermacentor and Rhipicephalus genera. Once infected, the horse may present a variety of symptoms, often difficult to distinguish from other equine diseases, making diagnosis a complex task.

The consequences of piroplasmosis

Piroplasmosis can have a wide range of consequences, from mild fatigue to life-threatening complications. In addition to piroplasmosis, other so-called piro-like diseases (such as anaplasmosis and borreliosis) present similar symptoms. These diseases, which are also transmitted by ticks, are a serious threat to horses' health.

Symptoms of piroplasmosis in horses

Clinical signs to watch out for

Piroplasmosis can manifest itself as a combination of various symptoms:

• High fever
• Anemia: destruction of red blood cells, causing pale mucous membranes (gums, eyelids).
• Fatigue and general weakness
• Icterus (jaundice): yellowish tint of the skin and mucous membranes
• Hemoglobinuria: dark red to brown urine with an unusual odor
• Loss of appetite and weight
• Respiratory distress

When these symptoms appear, it's crucial to consult a veterinarian without delay.

Piro-like diseases: Symptoms and diagnosis

Equine anaplasmosis

Caused by Anaplasma phagocytophilum, this disease results in :

• High fever
• Lethargy
• Swelling of the lower limbs
• Ataxia (motor coordination disorders)

Diagnosis is based on blood smears and PCR tests.

Equine Ehrlichiosis

Caused by Ehrlichia risticii, this disease is also transmitted by ticks and can cause :

• Fever
• Severe diarrhea
• Rapid dehydration

Equine borreliosis (Lyme disease)

This disease, caused by Borrelia burgdorferi, leads to :

• Muscle and joint pain
• Moderate fever
• Neurological symptoms (facial paralysis, limb weakness)
• Intermittent swelling of joints

Conclusion

Piroplasmosis and piro-like diseases represent a real danger for horses. Prompt treatment is essential to reduce the risk of complications. If in doubt, always consult a veterinarian to ensure your horse's health.
