''T. leonina'' is a little smaller (up to 10cm), but otherwise similar in appearance to ''[[Toxocara canis|T. canis]]''. With a female worm, the easiest way to tell them apart is to cut it open and examine the eggs under the microscope. The eggs of ''Toxoscaris'' are smooth and pale; whilst those of ''Toxocara'' species are dark and pitted.

Scientific Classification

Class Nematoda
Superfamily Ascaridoidea

The biology of T. leonina is generally similar to that of T. canis, except:

  • it infects both felidae and canidae
  • in the final host:
    • there is no prenatal transmission
    • there is no transmammary transmission
    • there is no hepato-tracheal migration
  • in 'paratenic' hosts:
    • develops to L3 in tissues (the 'paratenic' hosts therefore are really facultative intermediate hosts).

Transmission is via ingestion of the embryonated egg or an infected 'paratenic' host. The zoonotic potential is uncertain, but T. leonina is not thought to be as hazardous as T. canis.
