The migration and distribution of Toxocara canis larvae in the tissues of Japanese quails, infected orally with 5 x 10(3) infective eggs, were studied, as well as the re-infectivity of these larvae in mice, inoculated with 50 larvae obtained from the liver of these quails. Post-infection, the highest concentrations of larvae were found to be present in the liver of quails while only a few migrated to other tissues like lungs, heart, muscle and brain. The migration and distribution of the larvae in the tissues of mice were studied by necropsy on days 6 and 12 post-infection. On both days the highest number of larvae, 11 and 10, were recovered from the carcase followed by six and seven from the leg muscles and four and eight from the brain, respectively. A few larvae were recovered from the liver, lungs and viscera. This implies that the larvae had a special affinity for the muscle and brain tissue of mice, unlike in the quails. The role of these larvae in relation to paratenism is discussed.

D007814	Larva	Wormlike or grublike stage, following the egg in the life cycle of insects, worms, and other metamorphosing animals.	Maggots,Tadpoles,Larvae,Maggot,Tadpole
D008297	Male		Males
D009068	Movement	The act, process, or result of passing from one place or position to another. It differs from LOCOMOTION in that locomotion is restricted to the passing of the whole body from one place to another, while movement encompasses both locomotion but also a change of the position of the whole body or any of its parts. Movement may be used with reference to humans, vertebrate and invertebrate animals, and microorganisms. Differentiate also from MOTOR ACTIVITY, movement associated with behavior.	Movements

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D001715	Bird Diseases	Diseases of birds not considered poultry, therefore usually found in zoos, parks, and the wild.
