Abstract

Cerebrospinal baylisascariosis as cause of central nervous disorders in two blue-fronted Amazons (Amazona aestiva).

Abstract

A breeding pair of blue-fronted Amazons were submitted for PM examination, having died about 4 weeks after being housed in an outdoor aviary. The birds started to show torticollis, coordination disorders and movement difficulties about 14 days after being put in the aviary. The aviary had previously housed a raccoon (Procyon lotor) for 1.5 years. PM examination of the birds, revealed miliary granuloma in the liver due to nematode larvae, and larvae were also found in the brain. These were identified as Baylisascaris procyonis and had originated from the raccoon, despite the fact that the owner had removed raccoon faeces and wastes from the aviary on a daily basis and had disinfected the soil.
