'''''Protostrongylus''''' species
=== Life-Cycles ===
**Indirect life-cycle involving mollusc intermediate hosts
**L1 passed in faeces, penetrate foot of mollusc, develop to L3 in 2-3 weeks
**Infected mollusc ingested with grass
**L3 released by digestion and travel to lungs by lymphatic route
**Adults found in alveoli/parenchyma (''Muellerius'') or small bronchioles (''Protostrongylus'')
**Prepatent period 6-10 weeks (''Muellerius''), 5-6 weeks (''Protostrongylus'')
=== Epidemiology ===
**High prevalence because of wide range of intermediate hosts, prolonged survival of larvae in faeces, long periods of patency (>2 years) and poor host immunity
