Crenosoma striatum , also known colloquially as the lungworm , is a host-specific parasite of the hedgehog . It affects the windpipe , the bronchi and the alveolar ducts ( ductus alveolares ).
Features and life cycle
Adult males are 5–7 mm long, females 10–13 mm.
The viviparous females deposit larvae I around 300 µm in size. They are coughed up, swallowed, excreted with the feces and penetrate the snails intermediate host via the foot . The infectious larva III develops in about three weeks and is ingested by the hedgehogs when the snail eats. The prepatency is three weeks. However, hedgehogs can also ingest the eggs directly if they are in places that are dirty with infected feces. The parasite is also passed on to the young in breast milk. Crenosoma striatum occurs everywhere in Europe and Asia where hedgehogs are common.
Infestation symptoms and diagnosis
Most hedgehogs living in the wild are infested with lungworms. While no symptoms need to be recognizable in the case of mild infestation, coughing, shortness of breath, weight loss, decreased appetite, weakness and reduced activity can be observed. In extreme cases, an infestation can lead to the death of the animal.
For diagnosis, the feces can be examined microscopically for larvae (see coproscopy ).
