title: Systemic trichomoniasis in a squab operation.
abstract: Systemic trichomoniasis was responsible for severe morbidity and mortality in a commercial squab operation. Squabs of 1 to 3 weeks of age were primarily affected. Extensive caseous necrosis of the liver, heart, lung, and intestinal mesentery was observed grossly. Histologically, extensive heterophilic inflammation surrounded the necrotic areas and was observed perivascularly in areas that were uninvolved grossly. Numerous trichomonads were demonstrated in affected tissues with Bodian's silver stain.
