Abstract
An adult female lesser flamingo (Phoeniconaias minor), caught in the Africa n Rift Valley in 1991 and subsequently housed at the Baltimore Zoo, died of severe visceral gout in 1996. Necropsy revealed a white, moderately firm, nodular lesion, 1 cm in diameter, in the serosal wall of the small intestin e. Although it was initially thought to be a tumor or focal granuloma, hist ologic examination revealed multiple cestodes deeply embedded at the base o f the crypts between the intestinal villi, with their massive scolices (up to 3.4 mm in diameter) distending these spaces into multiple diverticulae. The mucosal epithelium surrounding the scolices was severely attenuated. Ar ound the diverticulae, in the submucosa and muscularis, was a mild to moder ate lymphocytic reaction and mild fibrosis. The proximity of multiple scoli ces and extensive invasion of host tissue suggested that the infection occu pied a preexisting lesion. The cestodes were cyclophyllids but were distinc t from any species previously reported from flamingos. Helminths should be included in differential diagnoses for gastrointestinal nodules in flamingo s.
