Toxocara

Toxocara

a genus of nematode parasites in the family Ascarididae.

Toxocara canis
the adults are found in the small intestine of the dog and fox; infection is via oral, transmammary and transplacental routes; the larvae migrate through tissues, including to the fetus where they establish a prenatal infection, eventually passing through the lungs and then to the alimentary tract. In hosts other than the dog and fox migration in abnormal tissues occurs and the life cycle is not completed. Is the cause of ocular and visceral larva migrans in humans.
Toxocara cati
the adults are found in the small intestine of domestic and wild cats. Larvae pursue a migratory course through tissues but intrauterine infection of the fetus does not occur.
Toxocara pteropodis
found in flying fox bats.
Toxocara vitulorum
occurs in the small intestine of cattle, buffalo and in sheep and goats. Calves are infected via the milk of the dam.

Se ha especulado que las condiciones climaticas pueden afectar la presencia de Toxocara en el suelo [4], por lo que es posible que las condiciones de altitud (2600 m) y baja temperatura media anual (12 [grados]C) de Toluca explique la menor presencia de Toxocara en comparacion con otras localidades, dado que tambien existe la presencia del fecalismo canino como causa principal de la contaminacion [10].
Otro factor de importancia en la diseminacion del helminto son las malas practicas higienicas [16], que permiten la contaminacion de Toxocara en los humanos [5], particularmente en los ninos de uno a cuatro anos de edad, donde la toxocariosis es mas frecuente debido a los habitos de geofagia, onicofagia, no lavarse las manos, entre otros [6, 19].
