Technical information
Dirofilaria immitis, also known as heartworm, is a parasitic roundworm that causes the so-called heartworm disease (dirofilariasis) in dogs and occasionally in cats worldwide. Adult worms prefer to settle in the right ventricle and the pulmonary artery, and if left untreated, can lead to severe health damage such as pulmonary hypertension, heart failure, and organ damage.
Transmission and Life Cycle
Transmission occurs through mosquitoes (e.g., Aedes, Anopheles, Culex), which ingest microfilariae during blood feeding and later transmit infective larvae to other animals. After infection, the larvae migrate through the host's tissues and develop into adult worms in the blood vessels — a process that takes about 6–7 months in dogs and 7–9 months in cats.
Symptoms
In dogs: Chronic cough, decreased stamina, shortness of breath, weight loss; in advanced cases: heart failure, effusions.
In cats: Often asymptomatic or sudden death, coughing, shortness of breath, vomiting, neurological symptoms, FIP-like progression.
Diagnosis
Diagnosis is based on:
- Antigen rapid tests (e.g., VetFor™ Heartworm Test Kit)
- Detection of microfilariae in blood smears or via the Knott test
- Imaging (cardiac ultrasound, X-ray)
Treatment
In dogs: Antiparasitic drugs such as melarsomine, possibly combined with doxycycline (to target Wolbachia bacteria). Additionally: corticosteroids to reduce inflammation.
In cats: Treatment is symptomatic, as adulticide therapy is risky. Prevention is especially important in cats.
