The life cycle of ''T. axei'' is typical of the superfamily [[Trichostrongyloidea]], and is direct (see [[Trichostrongyloidea - Overview|Trichostrongyloidea life cycle]]. The eggs develop into infective L3 in around one week. The larvae are then ingested by the host, and the larvae become unsheathed.  They penetrate the mucosa of the small intestine. There are two further moults, and then the larvae become adults.

TRICHOSTRONGYLUS AXEI

General

  • Small trichostrongyle, <5mm long; stomach.

Life-Cycle
