There is a risk to the sight, particularly in children, from an infection called toxocariasis which is caused by a parasite present in animal faeces, predominantly dogs. [it.bab.la]

The natural final host is the arctic fox; sledge dogs were kept in large numbers by the Yup'ik residents of the island, and voles were most commonly affected where dogs were present. [bioone.org]

• Fever

  Results The clinical features were as follows: 24 children (44.4%) were asymptomatic, pneumonitis was found in 9 (16.7 %), hepatomegaly in 6 (11.1 %), acute posterior uveitis in 5 (9.3 %), strabismus in 5 (9.3 %), leukocoria in 4 (7.4 %), fever in 3 [analesdepediatria.org]

• Asymptomatic

  The patients were divided into three groups: asymptomatic children (n 5 24), those with visceral larva migrans (n 5 16) and those with ocular larva migrans (n 5 14). [analesdepediatria.org]

• Pneumonia

  There was 1 case of keratitis, 1 of cataracts, 1 of myocarditis and 1 case of pneumonia with pleural effusion. Some patients showed more than one clinical feature. Four children experienced loss of vision in the affected eye. [analesdepediatria.org]

• Hepatomegaly

  Results The clinical features were as follows: 24 children (44.4%) were asymptomatic, pneumonitis was found in 9 (16.7 %), hepatomegaly in 6 (11.1 %), acute posterior uveitis in 5 (9.3 %), strabismus in 5 (9.3 %), leukocoria in 4 (7.4 %), fever in 3 [analesdepediatria.org]

The patients received treatment with albendazole 10-15mg/kg/day for 15 days or thiabendazole 25 mg/kg/day in two series of 7 days. [analesdepediatria.org]

The Oxyurida and Rhigonematida are occasionally placed in the Ascaridida as superfamily Oxyuroidea, but while they seem indeed to be Spiruria, they are not as close to Ascaris as such a treatment would place them.[1] These "worms" contain a number of [en.wikipedia.org]

Repeated exposure of voles apparently intensified the immune response to the extent that larvae from exposure subsequent to the first were retarded in development and might have been prevented from completing migration to the musculature. [bioone.org]
