[2 trichostrongyloid nematode parasites in an African murid. IV. Migration in the vertebrate]

For the species both oral and skin penetrations are possible. The ingested infective larvae pass through the excretory pore of a stomachal gland, leave the bottom of the gland through a blood capillary at H8, cross the liver (portal vein, sinusoids, sus-hepatic vein), the right heart and reach the lung around H12; they dwell in the pulmonary alveoli from H12 to D3, in the bronchi from D3 to D4, ascend the trachea, are swallowed by the host and reach the intestine on D4 and 5.
