Today’s zoos, however, are serving many roles, chief among them: species conservation of captive animals. The biggest zoo in Brazil, S?o Paulo Zoological Park Foundation, has among its 2000 animals and many species of wild cats. The presence of domestic cats living freely in zoos </span><span style="line-height:1.5;">is</span><span style="line-height:1.5;"> common and can be a source of spreading disease.

The results of this parasitological analysis have been obtained from the laboratory of clinical analysis and correspond to the 4-year period beginning January/2009 and ending December/2012.

We presented a case of progressive blurring of vision in a single eye of a 9-year-old boy.The presence of anti-toxocara antibody in serum samples helps to confirmation the diagnosis in our patient.Despite of treatment,the boy had lost his vision on the affected eye.展开更多
