In a fit of excitement Bigjon uttered:

....."People can become infected with a worm that causes blindness simply
by stroking the coats of dogs that carry the parasite. The finding
challenges previous assumptions that the worms only spread to people who
come into contact with dog faeces, and suggests that owners need to be
extra vigilant in washing and worming their pets"...[ ]..."Toxocara canis,
a nematode worm that grows up to 20 centimetres long in the intestines of
dogs. In infected people the worms can grow in the back of the eye, causing
lesions which can interfere with vision or be mistaken for tumours.
Occasionally they cause blindness. If they migrate to other organs such as
the liver or lung they can also cause a form of toxocariasis, whose
symptoms include periodic bouts of lethargy, similar to glandular
fever"......
