Aetiological agent
Angiostrongylus vasorum
Principal vector
Snails, snakes and sometimes toads
and frogs.
Disease
When a dog swallows an infected host,
the L3 larvae penetrate through the wall of
the digestive tract. These migrate to the
mesenteric lymph nodes, mutate into L4
larvae and finally immature adults that then
enter the circulation. After 10 days, they
reach the right ventricle and the pulmonary
artery; here they reach sexual maturity and
the females lay embryonated eggs. These
develop into L1 larvae, which enter the alveoli
and bronchi, migrate to the trachea to
be swallowed and eliminated in the faeces.
They are eliminated intermittently, alternating
between periods of high elimination
and periods of no parasites in the faeces.
Clinical signs
The disease may remain subclinical for
months or years.
Persistent cough and severe dyspnoea,
lethargy, exercise intolerance, poor coagulation,
prolonged or excessive bleeding,
petechiae, vomiting, abdominal pain, lumbar
spinal pain and heart failure, ascites,
pulmonary congestion.
