Photomicrographs of the small intestine from a Western gull (Larus occidentalis) from California, USA
linkPhotomicrographs of the small intestine from a Western gull (Larus occidentalis) from California, USA. H & E stain. (A) Expanding the small intestinal lumen and distorting intestinal villi are multiple adult metazoan parasites (arrow); similar parasites are within cavitations in the intestinal wall or serosa (arrowhead).
