Q

Describe the general life cycle of D. viviparus

A
  • Adult worms exist in the lung
  • They produce eggs which are released in faeces as L1
  • L1 develops into L3 in the faeces
  • L3 is ingested and the cycle repeats

Q

How do you diagnose D. arnfieldi

A
  • Clinical signs such as cough (in horse, donkeys don’t seem to get clinical signs)
  • Look for larvae or eggs in faeces (in donkeys)
    Lung sounds on ausculations (in horses)

17
Q

What species does Angiostrongylus vasorum affect

A

Dog

18
Q

What species does Aelurostrongylus abstrusus affect

A

Cat

19
Q

Describe the general life cycle of A. vasorum

A

Indirect life cycle

  • Adults exist in the pulmonary arteries
  • Eggs are excreted into the pulmonary capillaries
  • L1 penetrates the capillaries and alveolar wall
  • L1 coughed up and swallowed
  • L1 excreted in faeces
  • L1 develops to L3 in slug/snail
  • Dog eats affected slug/snail
  • Larvae moves to right heart and pulmonary arteries via lymph or circulatory systems
20
Q

How is A. vasorum diagnosed

A
  • L1 detected in faeces
  • Bronchoalveloar lavage fluid
  • Radiograph of chest
21
Q

What are the hosts involved with A. abstrusus

A
  • Cats= definitive host
  • Snails/ slugs= intermediate host
  • Rodents, birds and amphibians= paratenic hosts
22
Q

How is A. abstrusus diagnosed

A
  • Larvae in faeces
  • Larvae in Bronchoalveloar lavage fluid
  • Radiograph of lungs
23
Q

Describe the life cycle of A. abstrusus

A
  • Adults are in the lungs
  • Eggs are produced in the alveoli
  • L1 moves into the trachea and is coughed up and swallowed
  • L1 passes in cat faeces
  • Slugs/snails ingest the faeces L1- L3
  • Cat either ingests slug/snail or L3- arrest in paratenic host whic is ingested by cat
24
Q

What species does Ascaris suum affect

A

Swine (pigs )

25
Q

Describe the general life cycle of Ascaris suum

A
  • Adults and L4 are in the intestine
  • Eggs are passed in the faeces
  • Pigs ingest the eggs
  • Eggs hatch in the intestine to form L2
  • L2 migrates to the liver via the heptaic vein and forms L3
  • L3 exists in the heart and lungs causing symptoms
26
Q

What species does Toxocara canis affect

A

Dogs
