Enteric pythiosis in a Jindo dog

Abstract
|
|
|
A case of enteric pythiosis in the jejunum is reported in a 28-month-old, male Jindo dog.
Grossly, a 20㎝ segment of the cranial jejunal wall was markedly thickened to a thickness of 10cm and the lumen was narrowed.
Histological examination of the jejunum reveals transmurally affected multifocal to coalescing granulomatous inflammation.
The granulomatous foci were composed of a necrotic center with neutrophilic infiltration and occasionally non-parallel, branching, septate hyphae surrounded by numerous epithelioid macrophages, multinucleated giant cells, lymphocytes and fibrosis. Multinucleated giant cells occasionally contain fragment of hyphae.
The diagnosis was based on light microscopical studies and positive PAS and immunostaining for Pythium insidiosum. This is believed to be the first reported case of canine enteric pythiosis in Korea.
