Baylisascariasis

Baylisascariasis is an infection with the US in raccoon endemic ascarids (Baylisascaris procyonis), which can lead to fatal infections of the CNS in humans.

An infection usually occurs in children who play in the dirt or other objects contaminated with the feces of raccoons. It occurs in the United States, above all in the Middle Atlantic, Midwest and Northeast. Although Baylisascariasis in humans is rare, it is of concern because a large number of raccoons living near humans and the infection rate of B. procyonis in these animals is high.

Although Baylisascariasis in humans is rare, it is of concern because a large number of raccoons living near humans and the infection rate of B. procyonis in these animals is high. A migration of the larvae through a variety of tissues (liver, heart, lungs, brain, eyes) leads to VLM and OLM syndromes similar to those of toxocariasis. But unlike Toxocara larvae Baylisascaris larvae grow in the CSF further to a considerable size (up to 24 cm in females and 12 cm for males) and cause eosinophilic meningoencephalitis. Tissue damage and symptoms and signs of Baylisascariasis are often difficult because Baylisascaris larvae continue to grow, tend to spread and not easily die. The diagnosis is difficult because serologic tests are not commercially available, but CSF or serum can be tested in the Centers for Disease Control and Prevention for antibodies if the index of suspicion is high. The views of a larva during an eye examination is often a clue. If the suspected infection is high, immediate treatment with albendazole can (25 to 50 mg / kg p.o. 1 times a day for 10 to 20 days) be effective.
